5 Benefits of Healthy Indoor Air in Houston, TX

If your Houston, TX home has poor ventilation or a dysfunctional HVAC system, you understand how stuffy and unpleasant the air inside can get. Here are some benefits of healthy indoor air.

1. Easy Breathing

Healthy air is free from dust, excess humidity and unpleasant odors. This is why it enables you to breathe easily. The easy breathing supplies your body with adequate oxygen and reduces the stress on your heart and lungs.

2. Fewer Health Issues

The quality of air inside your house significantly impacts your health. For instance, maintaining high-quality air prevents issues like headaches and airborne diseases. You will also notice that you rarely sneeze or experience throat irritation.

For this reason, ensure that you install high-quality air filters, such as fiberglass and electrostatic types. They will clear the contaminants in the atmosphere to protect you and your family from diseases associated with polluted air.

3. High-Quality Sleep

Sleeping in a healthy environment is very comfortable since you do not have to deal with respiratory irritation or allergens. The clean indoor air ensures that you wake up feeling rested and refreshed.

On the contrary, sleeping in a dusty room is an unpleasant experience because you will spend the entire night sneezing and tossing. The dust and pollen in your room can also cause various sleeping problems like sleep apnea..

4. Lower Energy Bills

Another advantage of maintaining healthy indoor air is that it economizes your energy bills by boosting your HVAC system’s performance. It also prevents it from straining and consuming a lot of energy, trying to eliminate indoor pollutants and maintain a comfortable environment.

The smooth performance further prevents premature breakdowns. For this reason, consider hiring a qualified tech to install a ventilator.

5. More Comfort

Improving indoor air quality will also make your Houston, TX home more comfortable. It ensures that you don’t have to deal with expensive energy bills, bad smells or frequent airborne illnesses. The healthy air will make you more productive if you work from home.

In summary, every homeowner in Houston, TX needs a comfortable place to work or rest after work. Contact Davis Air Conditioning & Heating, Inc. for reliable AC installation services to ensure healthier living.

What Happens If You Skip AC Maintenance?


We talk about the importance of getting regular AC tune-ups each year on a regular basis. We want to make sure that everyone gets a chance to learn how helpful this service is. With this said though we understand if a lot of people are still questioning if this service is truly worthwhile. Can you skip it for just one year, maybe two, and get alright?

While skipping air conditioning maintenance in Pinecrest, FL isn’t going to set you up for an immediate breakdown, there are problems that will pop up because of it. Below we want to explain what the impact of skipped maintenance can be so you know exactly what the risk is that you might be taking…and why it is better to get that tune-up each year.

The Consequences of Skipped Maintenance

If you are considering skipping system maintenance this year, we want you to understand fully the risks that you may be facing as a result.

Reduced energy efficiency

Each year that your air conditioner goes without maintenance it can lose up to 5% of its energy efficiency. That means that each year you run it without getting it a tune-up, the system becomes increasingly inefficient and, by default, more expensive to run.

Minimized system lifespan

An air conditioner that isn’t maintained won’t break down overnight. However, it is more likely to need replacement much sooner than it would otherwise. Without maintenance, you are likely to need an AC replacement after only 10 years of use.

Reduced effectiveness

Another issue that can arise from skipped tune-ups for a year or more can be that your air conditioner is less effective at cooling your home. This is because small problems like dirt build-up, loss of lubrication, and overall wear and tear are allowed to accrue for longer and worsen as a result, undermining the cooling process.

Increased repair risk

Increased strain on your AC can result from skipping maintenance which can increase the chances that you need repairs more frequently. Without maintenance, you can end up needing repairs on a nearly yearly basis. In contrast, a well-maintained system can avoid up to 85% of the repairs that it could need otherwise.

Possible voided warranty

A good number of air conditioners actually require regular maintenance to keep their warranty intact. That means that the choice to skip an air conditioner tune-up for even one year can present the risk of voiding your system warranty. This may not present an immediate problem but it can sting pretty badly if you need a repair in the near future that you now have to pay out of pocket for.

As you can see, while maintenance does take time and money, it is well worth both of these resources. This is because maintenance is going to benefit you far more in the longer run, and will even help you save money too.

How to protect your AC from hurricanes

At, our writers create solutions that put you in control of your HVAC system. Our product reviews and recommendations are researched and backed by real buyers and industry experts, not dictated by our partners.

hurricane blowing trees

Hurricane season lasts June 1 to November 30, with September as the most active month for hurricanes in the Atlantic. The National Oceanic and Atmospheric Association (NOAA) forecasted an above-average hurricane season this year. 

NOAA predicts 14-21 tropical storms in the 2022 season, most of which will occur between mid-August and mid-October. Typically, there are 14 tropical storms per season, which peaks around September 10.

With tropical cyclones becoming more frequent and intense due to climate change, consider adding a few steps to your hurricane prep to protect your HVAC equipment. 

How to prepare your AC for a hurricane

Window AC

If you have a window air conditioner, it’s best to unplug it and remove it as a hurricane approaches. Strong winds can blow a window AC out of place, damaging the unit, your window, and anything in and around your home.

If removing your window air conditioner isn’t possible, purchase a cover with straps like this one to protect it during extreme weather. 

Portable AC

If you have a portable AC inside your home, we recommend running it until the storm arrives. This will cool your home as much as possible before a potential power outage. When the storm hits, unplug the AC to avoid damage due to power surges.

Central AC

Defending your central AC against a hurricane is a little more complex. Follow these steps to keep your AC safe and your home comfortable.

☂️ Put on a waterproof cover Purchase a waterproof cover to protect your AC compressor from the elements. Make sure it’s the right size to cover the whole unit. 
🌊 Elevate the slab In hurricane-prone areas, you should mount your AC on a concrete slab. If yours is not high enough to protect from potential flood waters, engage a contractor to make it taller.
🔩 Check the anchor bolts Tighten the bolts that anchor your compressor to the concrete slab. Yours should be able to withstand 160 MPH winds at a minimum.
❄️ Cool your home Drop the temperature on your thermostat to cool your home before the storm arrives. Close all windows and doors. This will help keep you comfortable if the power goes out.
⚡ Shut the power off Turn your AC off at the breaker box as the storm approaches. This will protect it from power surges.
🔌 Consider a surge protector An HVAC pro can install a surge protector designed to protect your compressor if you live in an area prone to power outages or lightning strikes.
🔒 Secure outdoor objects Put away patio furniture and other large items that may blow into your AC compressor, causing damage. Make sure to trim large tree branches.

Once the storm passes and power restored, go outside and check your compressor for visible damage. Clean out any debris that’s become stuck in the unit. If everything looks OK, turn the power back on and start your AC.

Contact an HVAC professional if you need help getting your AC prepped for hurricane season, or if you suspect a hurricane has damaged your AC.

Best air conditioners for coastal homes

Several manufacturers make HVAC equipment specially designed to withstand the unique challenges of coastal climates. When you’re ready to upgrade your system, consider one of these options.

Carrier coastal ACs

Carrier’s Comfort and Infinity lines of central AC compressors and heat pumps have coastal-specific models. These units feature the company’s WeatherShield protection, which eliminates corrosion from salt air. 

Since most coastal areas experience more temperate climates, we recommend installing a heat pump rather than an AC compressor. Heat pumps have a number of advantages, including improved energy efficiency, cost savings, and the ability to provide both heating and cooling. 

Carrier recommends its coastal systems for homeowners who live within 10 miles of the shoreline.

Bryant coastal ACs

Bryant is a sister brand of Carrier. Many of its models are the same as Carrier’s, but they’re often priced more affordably.

Bryant’s Legacy and Evolution lines of air conditioners and heat pumps have coastal models designed to withstand corrosion from salt air. They also have DuraGuard Plus protection, including a steel coil guard and baked-on powder coating. 

Trane coastal ACs

Trane doesn’t offer coastal-specific models. However, its ACs and heat pumps include aluminum coils and a painted finish that resist corrosion and rust. 

I need a coastal AC!

Though you should still perform the prep tips above when a hurricane is on its way, purchasing an AC or heat pump intended for coastal environments can extend the life of your investment.

Lennox mini split troubleshooting

At, our writers create solutions that put you in control of your HVAC system. Our product reviews and recommendations are researched and backed by real buyers and industry experts, not dictated by our partners.

If your mini-split isn’t working right, these Lennox mini split troubleshooting tips might help you fix it yourself. Of course, if you aren’t comfortable performing these tasks, call a certified HVAC pro. They can help you get your mini split back in shape. 

Connect me with an HVAC repair technician now 👩‍🔧

Lennox mini split is dripping water or not draining properly

First, check your air filters. You should clean these every few months. Dusty filters can cause a host of issues with your HVAC system because of reduced airflow.

Open your evaporator (the indoor cabinet) and remove the air filter. You can rinse it in the sink, or vacuum it with a hose attachment. When it’s clean, return it to the evaporator.

Mini splits remove moisture from the air, so there may be some condensation at your heat pump. But if it’s making a puddle, you have a problem. Some models do have a drain pan under the heat pump that collects condensation. It may be overflowing because of mold or debris.

Turn the power to your heat pump off at the circuit breaker. Clean out the drain pan with an old towel. Open the unit (you may need to unscrew the cover with a screwdriver). Look for clear tubing inside. If you see a visible clog or mold in the tube, use a shop vac to suck it out. Alternatively, you can remove the tubing and use your garden hose to clean it out before replacing it. 

If these Lennox mini split troubleshooting tips don’t work, call a technician. Your issue requires professional attention.

Lennox mini split is not heating or cooling

Check your thermostat. Set it at your desired temperature. Choose “cool” if you want AC or “heat” if you want heat. Put it on “auto” instead of “on.” If you choose “on,” the mini split will blow air when it’s not actively heating or cooling.

Go around your home and feel for air leaks. If you feel a draft, especially near a window or door, seal it with weatherstripping tape. Your mini split may be working but unable to keep up if the cool/warm air is escaping. 

Check the air filters. They may be dirty, blocking cool/warm air from entering the home. Open your indoor evaporator and remove the air filter. Vacuum it with your hose attachment or rinse it in the sink. You can purchase a replacement on Amazon – just be sure it’s the right size and compatible with your model. 

Call a professional if these Lennox mini split troubleshooting tips don’t help. It’s likely your refrigerant is leaking. If this is the case, the coils (metal tubing that zigzags inside your heat pump) may appear frozen.

mini split in home

Lennox mini-split is making unusual noises

Identify where the noise is coming from.

If you hear popping or clicking coming from your evaporator (indoor cabinet), it may just be the plastic cabinet expanding during use. No need to troubleshoot – this is normal.

Check the air filter if you hear a whistling sound coming from the evaporator. Pop it out and clean it. Vacuum it with a hose attachment or rinse it in the sink. Make sure you dry it thoroughly before putting it back.

If you hear gurgling or crackling coming from the heat pump (outdoor unit), it may be turning on defrost mode. This is part of its normal operation. 

If you hear clanking or jangling from the heat pump, turn off the power and remove the cover. You may need to unscrew it with a screwdriver. Check inside for any loose debris. If sticks, rocks, or leaves are inside, clean them out. Check for screws or bolts that have fallen inside. Make sure any visible screws are tight and holding the components in place.

If these tasks don’t alleviate the noise, or if you hear a more jarring noise like screeching or banging, call a professional for help. 

Book an appointment with a technician now.

Lennox mini-split has a strange smell

If your home smells of mildew, it’s possible the cause is your mini split. If mini splits aren’t cleaned regularly, they may not drain condensation properly. This excess moisture causes mold. The Environmental Protection Agency suggests calling an HVAC professional to handle mold removal properly. Check your owner’s manual for cleaning instructions. 

You may have a refrigerant leak if you detect a smell like vinegar or nail polish remover coming from your mini split. Call a technician. They can repair the leak and refill the refrigerant.

If you smell burning or an “electrical” scent coming from your unit, you may have wiring issues or a failing motor. This isn’t a DIY job – call an HVAC pro.

With any of these smells, it’s best to turn your mini split off until you can give it proper attention. You don’t want a mold odor spreading through your home. And you don’t want to further damage your system.

Lennox mini split troubleshooting resources

Lennox has a troubleshooting tool to help identify and fix issues with your system. Its site also has a product literature lookup, where you can find the owner’s manual for your model. These Lennox mini split troubleshooting resources may help you identify parts and determine whether you need to call a pro to fix your issue. 

If you’ve tried our Lennox mini split troubleshooting suggestions and still need help, reach out to a certified HVAC professional. A technician can also perform troubleshooting for you if you prefer not to do it yourself.

Why clean air ducts yourself? 

According to HomeAdvisor, it costs an average of $376 to have your air ducts professionally cleaned. The price may vary based on elements like accessibility and lifestyle factors (e.g., if you have pets or smokers in the house).

DIY air duct cleaning will save you money since it involves tools that most homeowners already have. It can also help prolong the life of your air conditioner and furnace. It eliminates dust in the home and may improve air quality for your family.

Is duct cleaning a waste of money?

Professional duct cleaning is worthwhile. Experts have tools that can reach deep into your ductwork. You won’t be able to access all of your ducts with DIY cleaning.

Additionally, duct cleaning companies can identify and remedy potential issues in your ductwork, including leaks or blockages.

Duct leaks and obstructions can damage your overall HVAC system without immediate attention. They may also result in increased utility bills.

Cleaning your air ducts yourself is also beneficial. You can do a DIY cleaning between professional cleanings to keep your system running smoothly. 

Connect me with an HVAC pro to clean my ducts.

Air duct cleaning: do it yourself

Cleaning your air ducts yourself is a simple process involving tools you probably own already. The job may take several hours, depending on the size of your home and the number of air registers.

Tools for DIY air duct cleaning

Before you begin, gather the necessary tools. These include:

You may also choose to invest in:

DIY air duct cleaning steps

1. Loosen up dust

If you have visible ductwork (in your attic or crawlspace, for example), lightly tap the outside with the handle of your cleaning brush. This will help loosen up dust and dirt.

Turn your thermostat to “fan” and “on.” Let it run this way for a few minutes. The air will push any dust closer to the registers where you can reach it for cleaning.

2. Turn off your HVAC system

The simplest way to make sure everything is off is via your electrical box. Turn off the breakers associated with your HVAC equipment, including the furnace and AC condenser.

Switch your thermostat to “off” as well.

3. Remove your vent grates

They may simply pop out. Or you may have to unscrew them first. Once the grates are off, cover the vent opening with a paper towel. If you have vents on a ceiling or a wall, you can use painter’s tape to secure the paper towel.

Covering the vent opening with a paper towel will prevent dust and debris from entering your rooms as you clean.

If you have different size grates, use a Sharpie to mark the inside with a number. Write the same number somewhere you can see it within the vent. This way, you’ll be able to easily match the grate to the correct vent later on.

Make sure you also remove and clean the grate on your air return. It’s typically larger than the other grates around your home.

4. Clean your vent grates

If your grates are plastic or metal, load them all into your dishwasher (top shelf for plastic) and clean them that way. Ensure they’re completely dry before replacing them.

If your grates are wooden or another material that’s not dishwasher safe, clean them in the sink. Run cold water over them and scrub the dirt and dust off. Dry them immediately to prevent warping.

5. Clean your vents

Start with one vent in your home. Remove the paper towel cover.

Insert your cleaning brush and jiggle it around to knock off anything stuck to the insides of the vent like spiderwebs or dust bunnies. We recommend using a toilet brush because of its long brush handle. But devote the brush to vent cleaning only. Don’t use a brush you’ve already used to clean the toilet (😬).

Insert your vacuum wand into the vent as deep as it will go. Vacuum out all debris.

Using a dampened rag or paper towel, wipe out the inside of the vent as far as you can reach. You can use tap water or your favorite multipurpose cleaner. 

Re-cover the vent with a paper towel when you finish. Continue this step until you’ve cleaned all the vents in your house.

6. Clean your air return

Take out the filter in your air return. Throw it away.

Use your cleaning brush, vacuum, and paper towels to clean out the air return. Only go as far as you can safely reach.

Replace the filter with a fresh new one.

7. Return your grates

Once your grates are clean and dry, remove the paper towel covering each vent. Replace the grates. You may need to use a screwdriver to secure them.

8. Clean your furnace blower compartment

Lots of dust accumulates in this area. To access it, remove the cover on your furnace. You may need to unscrew it with a screwdriver.

Take the furnace filter out and dispose of it. Use your cleaning brush to remove cobwebs and other stuck-on dirt from the compartment.

Vacuum out the blower compartment with your hose attachment. Then clean it out with a damp paper towel. Again, you can use plain water or your favorite multipurpose cleaner. If you can reach the furnace fan, clean that as well.

Replace the filter with a new one. Close and secure the furnace cover.

9. Clean your air condenser

Check out our step-by-step guide for cleaning your air conditioner

10. Turn your system back on

Enjoy your fresh ductwork!

Sound like too much work? You can always call a pro to get your ductwork spic-and-span. 

Connect me with a local HVAC expert.

Benefits of clean air ducts 

Fewer allergens

Keeping your air ducts clean reduces the number of allergens circulating in your home. This includes pet dander, pollen, and dust.

Unattractive to animals

Sometimes, rodents and birds can make their way into your ductwork. Dust and debris provide good nest-building materials for them. Clean air ducts are inhospitable – those pests will leave and find shelter elsewhere.

Additionally, air ducts can host insect infestations. These are much less likely to happen when your ducts are clean and dry.

Mold prevention

Clean, sealed ductwork keeps mold out. If your ducts are dirty with leaky joints, mold can flourish.

Mold inhalation is a potential health hazard. And it smells bad.

Don’t attempt to clean your air ducts yourself if you suspect mold growing in your ductwork. The Environmental Protection Agency recommends hiring a professional for HVAC mold removal. 

Lower utility bills

Clogged ducts make your HVAC equipment work harder than it needs to. Your system can function at max performance with clean air ducts, thus reducing your utility bills.

You may also save money by proactively finding and fixing potential furnace and AC repair issues in the cleaning process.

Prolonged HVAC system life

Maintenance is necessary to keep your HVAC system at its best. Duct cleaning should be part of your regular AC maintenance.

Be sure to schedule HVAC system checkups every year. We recommend having your ductwork cleaned professionally every 3-5 years. Between those appointments, clean your air ducts yourself to ensure your HVAC equipment lasts as long as possible.

The Noises You Don’t Want To Hear From Your AC


Keeping your air conditioner in proper working order when you live in Florida can honestly be more important than it could be elsewhere, if only because of how much longer our hot weather lasts–the truth is that is almost year-round.

With that said, it makes sense that you’d want to keep up on maintenance and address any air conditioning repair in Palmetto Bay promptly. Waiting can undermine your system’s ability to do its job and leave you with a system in need of replacement years too early.

When it comes to getting AC repairs, sooner is always better. So how can you figure out that you need to schedule a repair for your system? Keeps your ears on the alert!

Warning Noises You Might Hear From Your AC Unit

If you hear any of the following sounds from your AC while it is in operation, it is a good idea to reach out to schedule repairs for your system.

  • Rattling: If there is a part that is coming loose in your system, it may create a rattling or even a clanging sound. The sooner this is addressed the better since loose parts can easily cause additional damage to the system that requires more expensive repairs.
  • Hissing: Do you hear hissing while your AC is running? If so, don’t mistake this for the same sound as the air coming from your system. What you are actually hearing is the sound of refrigerant in its gaseous form escaping the refrigerant line. This will rapidly worsen the performance of your AC.
  • Bubbling: If you hear bubbling from your AC unit then it is also likely a sign of a refrigerant leak. The difference here is that you are hearing air bubbles in the portion of the refrigerant line where the substance is still in liquid form.
  • Screeching: Yikes! This sound is highly unpleasant on the ears but it will also be unpleasant for your system’s long-term effectiveness too. What you are hearing is metal grinding on metal such as when you have a dry blower motor belt.
  • Silence: Have you stopped to listen to your air conditioner and instead discovered that you can’t hear anything at all? This is a problem just as much as some of the noises we’ve discussed here. That is because a silent air conditioner is one that isn’t operating at all.

If your air conditioner is fighting to get your home cool then you might hear it make some of the sounds we’ve listed here. The faster your system is repaired, the sooner you can relax at home without worry. What’s more, quick repairs will help keep the overall cost of the service lower than it would be if you wait.

If you need repairs for your air conditioner, you’ll want to reach out to a professional team of technicians to get the task taken care of. This is something that you can trust our team with.

Contact Air On Demand to get your air conditioner back into peak condition again.

Thermostat wiring: how to install a thermostat

At, our writers create solutions that put you in control of your HVAC system. Our product reviews and recommendations are researched and backed by real buyers and industry experts, not dictated by our partners.

Bought a new thermostat and wondering if you can install it yourself? For some, thermostat wiring is a DIY job, but we won’t blame you if you opt for a local pro to handle the work.

We’ll give you all the information you need to successfully install your new thermostat below. Plus, we’ll explain the thermostat color code.

thermostat wires

Before you get started, make sure you have all the tools you need to complete the task. To install a thermostat, you’ll require:

If your new thermostat is a different shape and size than your existing one, you may also need spackle to patch holes and paint to match your current wall color. If you don’t have any leftover wall paint, have your wall color matched at the paint store before you begin.

Keep your cell phone nearby. Its camera will come in handy once you get started.

How to install a thermostat

1. Turn the power off

Go to your breaker box and switch off the power to your HVAC system, including the thermostat.

2. Remove the existing thermostat

Detach the cover by gently pulling it away from the base. If it doesn’t come off easily, check if there’s a screw or latch to release it.

You will see several colorful wires inserted into terminals. Use your phone to photograph the thermostat wiring. Doing so will help you remember which wire goes in which terminal. Alternatively, some new thermostats come with stickers to label the wires. (See our thermostat color code chart below to learn more about each wire’s purpose.)

Once you’ve recorded your thermostat wiring, disconnect each wire from its terminal. You’ll likely need to loosen each terminal screw to free the wiring. Next, remove the screws holding the thermostat base to the wall.

Carefully take the thermostat base off the wall. Hold the wires securely while doing this, so they don’t slip into the wall.

If your thermostat is more than 20 years old, it may contain mercury. Don’t just throw it away. Follow the mercury disposal guidelines for your area.

3. Find the common wire

The common wire is also known as the C-wire because it connects to the C terminal of the thermostat. It’s generally blue, but it may also be brown, black, or purple.

The common wire is necessary for modern thermostats – especially smart and programmable thermostats. Your old thermostat might not have used the common wire.

If you don’t see the common wire, look inside the hole where the other thermostat wiring is coming out. Carefully pull out any wires you find tucked inside the wall.

If you still can’t find it, contact an HVAC technician for help. Or choose a thermostat model that doesn’t require one.

4. Repair the wall

Now is the perfect time to fix your wall. Ensure the thermostat wiring is secure by taping or clamping the wires together – you don’t want them to slide back into the wall.

Fill any holes your old thermostat left behind with spackle. Touch up the wall with your current paint color.

Leave the hole with the thermostat wires open. Wait for the spackle and paint to dry before moving on to the next step.

5. Install your new thermostat

Place your new thermostat’s backplate on the wall. Make sure it’s level, and screw it into place. If it requires drywall anchors, use a drill to make your holes in advance.

Using a wire stripper, ensure about ⅜-inch of the wire is exposed. Then insert each wire into the corresponding terminal, referring to the photo you took or the labels you placed earlier.

Once you insert the wires, tighten the terminal screws. Attach the thermostat’s faceplate.

6. Turn the power on and complete the installation

Turn the power back on at your breaker box.

Complete the installation instructions for your specific thermostat model. For smart thermostat installation, that will likely include connecting to your home WiFi network.

Programming the thermostat is the final step. You’ll need some technical understanding to complete this portion, and we recommend following your installation manual step-by-step. If the programming isn’t completed successfully, your system won’t operate optimally.

Sound like too much work? Hire one of our licensed HVAC pros to install your thermostat.

Thermostat color code

In most cases, thermostat wires have a universal purpose. Each color usually corresponds with the same terminal regardless of the thermostat model.

There are occasional outliers. But for the most part, HVAC systems use the thermostat color code below.

Wire color Purpose Terminal


Power Rc and Rh


Heat pump O


Cooling Y


Fan G


Common C
White Heat W

If your thermostat controls both your heating and cooling systems (e.g., your air conditioner and furnace), you will have two red wires. The Rc terminal connects to the cooling system, and the Rh terminal connects to the heating system.

Depending on your unique HVAC system, you might not have all of these wires.

Thermostat wiring: the bottom line

Installing a thermostat is a DIY job that requires some basic knowledge and tools. If wires aren’t how you prefer to spend a Saturday afternoon (and we certainly don’t blame you), hire an HVAC professional to handle your thermostat installation.

Propane tank sizes for homes and commercial use

Larger propane tanks are typically buried underground near your home. When they’re nearing empty, you can pay a propane delivery company to refill the tank.

120-gallon propane tank uses

A 120-gallon propane tank is typically used to power multiple gas appliances in a home. This can include things like a clothes dryer or water heater.

250-gallon propane tank uses

Like a 120-gallon tank, a 250-gallon propane tank can fuel several home appliances.

350-gallon propane tank uses

A 350-gallon propane tank can power the heating system for a home smaller than 2,500 square feet. It’s the most common size for this use. Alternatively, you can use it for multiple large gas appliances.

500-gallon propane tank uses

500-gallon propane tanks are usually for mid-size and larger homes (2,500-4,500 square feet) and are the most popular for residential use. They can fuel the home’s heating system plus several gas appliances.

A 500-gallon propane tank can also be used commercially by businesses like restaurants or dry cleaners that rely on multiple large gas appliances.

1,000-gallon propane tank uses

A 1,000-gallon tank is used for heating and appliances in extremely large homes (more than 4,500 square feet). They’re also used for commercial and agricultural installations with high-volume gas needs. 

Not sure what size propane tank you need? Connect with an HVAC expert who can help.

Propane tank sizes for grilling and other small appliances

Smaller propane tanks are typically sold by weight. But a 20 lb. propane tank actually weighs more like 37 lbs.

When you buy a 20 lb. propane tank, you’re buying 20 lbs. of propane. The tank itself weighs an additional 17-ish lbs.

These smaller propane tanks are typically portable. You can exchange them for a new full tank when they’re empty.

20 lb. propane tank uses

This is the size propane tank you’ll see at the gas station or in front of the grocery store. It’s commonly used for things like:

  • Grilling 
  • Patio heaters
  • Mosquito traps
  • Small vented heaters (learn more about vented propane heaters here)

40 lb. propane tank uses

This propane tank size is commonly used for:

  • Commercial grills
  • Construction heaters

100 lb. propane tank uses

100 lb. propane may seem heavy, but they’re considered portable. They can be picked up and exchanged for a new tank when they’re empty. They’re not usually buried underground like some larger tanks.

100 lb. propane tanks fuel a single home appliance, such as a:

  • Clothes dryer
  • Kitchen stove
  • Fireplace
  • Water heater
  • Generator
  • Pool heater
