4 AC Noises That Should Prompt a Call to Your HVAC Specialist

When temperatures begin to soar, the AC unit in your Springhill, Florida, home becomes even more important. To lower your risks of major repair or a possible breakdown, it’s crucial to be vigilant about AC noises that your system is making to determine if it’s time to contact an HVAC specialist. If you notice your system making any of the unusual noises below, it might be time to call in the professionals.

Squealing AC Noises

Squealing coming from your system is likely a sign that one of your belts has become worn and is in need of lubrication or replacement. It’s vital to catch this problem before the belt breaks. Otherwise, you risk damage to the other components.

Hissing

Hissing is a sound you should never ignore. Odds are the noise is the result of a refrigerant leak in your system. Refrigerant leaking into the air is prohibited by the EPA, and if your system loses too much refrigerant, it will stop working properly. You’ll need to have a professional come out to replace your refrigerant line and recharge your system if this happens.

Rattling AC Noises

Rattling in your system typically means that something is loose and moving around in the system or that your motor mounts have failed. The longer you wait to have this fixed, the more damage the loose parts can cause to the components of your system.

Buzzing

Buzzing typically is a sign of problems with the wiring or the arcing connections. Even if they have simply come loose, you’ll want to address this issue early. If the buzzing is accompanied by a burning smell, it could be a sign of a serious electrical problem, and you should shut your system down until it’s repaired to prevent a dangerous situation from occurring.

If you’re hearing any of the sounds listed above, don’t wait for a small problem to become a significant one. Contact us at 866-881-5935 today. One of our Senica Air Conditioning technicians will diagnose your problem and help your system running efficiently again.

Boiler Cleaning, a Routine but Crucial Part of Facility Management

Boilers are built for a very specific reason: to provide heated water or steam using the least amount of energy, for the lowest cost, with little to no downtime. The facility manager’s job is simple and summed up in Cleaver-Brooks’ boiler efficiency guide; Routine inspections and preventative maintenance will pay for themselves in keeping boiler efficiency up and fuel costs down.” Unfortunately, maintenance staff sometimes take boilers for granted and forget that, just like any piece of HVAC equipment, a boiler needs maintenance, cleaning, and tuning. Without regular service, boiler performance diminishes and breakdowns become more frequent.

As scale accumulates on the boiler’s waterside from lack of cleaning, heat transfer through the tubes is limited. resulting in temperature spikes within the tube walls that lead to metal fatigue and tube damage. According to the Case Studies for Engineering Failure Analysis’ study on boiler tube failure in power plants, “[t]emperature shoot up above specification is the most common reason of failure for boiler tubes. The reason is either scale formation on internal and/or external surfaces under prolonged exposure at elevated temperature or non-uniform steam flow through partially blocked tubes. Internal scale formation reduces heat transfer rate across tube wall. “

Before the tubes fail, boiler performance will gradually deteriorate, sometimes for years, wasting thousands of dollars in extra fuel as the boiler runs longer to produce needed heat. Johnston Boiler Company has an excellent chart showing the extra boiler fuel costs with each fractional inch of scale buildup. Just a 1/32” layer of scale means an additional 8.5% increase in fuel burned by the boiler. Using Goodway Technologies boiler efficiency calculator, facility managers can calculate how much the built-up scale costs their company each year in extra fuel and lost efficiency. Looking at a 200 HP boiler using No. 2 oil, if the boiler runs 8,000 hours per year with a medium level of calcium scale, the boiler loses 5% of its efficiency costing a whopping $69,091 in additional energy per year! The money saved from descaling the boiler could pay for another maintenance engineer.

Luckily, descaling a boiler costs only a fraction of what the building loses in fuel and efficiency. The patented GDS-15-PH scale removal system with pH analyzer makes descaling easy and efficient. The GDS-15-PH’s fifteen-foot circulation hoses connect easily to boilers and the integrated pump draws descaling chemicals directly from the onboard storage container. There is no need for the operator to stand by, continuously check the pH, or to monitor the descaling progress. Once the unit is turned on, the technician can leave to do other work. The GDS-15-PH’s onboard computer analyzes the return pH and injects additional chemicals as needed. When the cleaning is finished, the neutralized waste water can be safely poured down the drain in most cases, but check your municipality rules first.

Soot laden boilers have even more dangerous consequences than just poor operation. Bryan Boilers Installation and Operating Service Manual for their forced draft steam boilers cautions “[i]f either soot or condensation is apparent [in the combustion tubes], a boiler service technician should be consulted. The presence of soot indicates poor combustion and possibly hazardous boiler operation. Failure to do so may result in fire, explosion potential, or asphyxiation. A combustion test and burner adjustments should be undertaken at once.”

An article by The National Board of Boiler and Pressure Vessel Inspectors provides several examples of how accumulated soot from inadequate combustion air caused carbon monoxide poisoning in maintenance staff. Soot accumulation inside your boiler is a serious issue, but is mitigated with proper tuning and preventative maintenance including cleaning the tubes. When boiler fire tubes are severely fouled, technicians need a cleaning system that allows for removing soot and scale without loose ash escaping into the room and covering everything including the workers. One of the easiest ways to get boiler tubes clean is with Goodway’s RAM-4X-KIT Heavy-Duty Turbine Firetube Boiler Cleaning System. The RAM-4X-KIT includes the RAM-4X machine with a powerful 1HP motor that rotates a flexible shaft tipped with a cleaning tool. The flexible shaft is fed down the boiler tube scraping away combustion contaminants as it travels. The cleaning kit includes an integrated vacuum that draws out loose debris so soot is contained within the system instead of blowing into the mechanical room. The RAM-4X and GCT-540 Soot Vacuum are wheel mounted to make it easy to move between boilers, reducing setup time and giving more time for maintenance personnel to clean and move on to other tasks.

Neglecting your facility’s boiler can mean higher fuel usage/cost, greater wear and tear on the equipment, and a possible health and safety risk to technicians in the mechanical room. The cost of annual descaling and tube cleaning is small compared to the price of a major boiler repair or the inconvenience to tenants when they don’t have heat. Goodway offers total cleaning solutions for any size or type of boiler to keep your buildings warm and running efficiently.

Does It Provide All the Services You Need?

When picking an HVAC company, you need to make sure it can handle all of your HVAC needs. Does it offer emergency repair service whenever you need it?

Are the Service Technicians NATE-Certified?

3 Signs of Poor Indoor Air Quality (and How to Fix It!)

Certain contaminants and airborne pollutants can have a negative impact on the air quality in your home. We know your family’s health is your top concern. It’s important for homeowners in Houston, Texas, and the surrounding area to know these three signs of poor indoor air quality and how to fix it.

1. Cold and Allergy Symptoms

Most people write off a stuffy nose or a sneezing fit as the sign of a cold or allergy season. If your symptoms go away when you leave the house, it’s possible there’s more to it. Poor indoor air quality can lead to congestion, coughing, watery eyes, headaches, or a sore throat. If you find your symptoms get worse over time, schedule a duct cleaning with one of our HVAC technicians. We’ll clean the dust, dirt, and other debris out of your ductwork so air can flow freely.

2. Dust Build-up

Do you find a need to dust your home more often than usual? Excess dust buildup around your vents and on household surfaces is a common sign of poor indoor air quality. A good way to solve the problem is to have one of our qualified technicians replace your air filter and clean your vents. Clean filters and vents trap dust inside, while dirty vents circulate it throughout the house.

3. High or Low Humidity

Humidity levels are an important indicator of air quality. When they are too high or low, your house can feel muggy or dry. This can lead to allergic reactions or worsen breathing conditions, such as asthma. We can test the humidity levels in your home and install a humidifier, dehumidifier, or air conditioning system to help solve the problem.

Poor indoor air quality is not something you want to overlook. Over time, it can have a negative impact on your family’s health. Contact Davis Air Conditioning & Heating to have one of our trained professionals check the air quality in your home. Visit our website or call 888-710-5530.

Help! My AC Still Won’t Cool My Home!

man-fan-chair-hatThere is nothing quite worse than an ineffective air conditioner, especially during a hot summer day! But, what do you do if your air conditioner is in mint condition and your still not getting the relief you’re looking for?

What if we told you that the reason your home isn’t getting cool enough has nothing to do with the air conditioner itself? What do we mean by that, you ask? Well, sometimes, the reason your home isn’t keeping cool is due to outside factors, like the amount of insulation you’ve got in your home or even faulty ductwork.

Below, we’ve described some of the ways HVAC techs like us can give you the cooling relief you need to enjoy a more comfortable summer. Keep reading to find out more!

Here’s What We Can Do

There are two main ways that we can help you achieve greater cooling output in your home:

1. Attic Insulation Services

Insulation is one of the best ways to improve the efficiency and effectiveness of your home’s heating and air conditioning systems. While many homeowners believe that insulation is there simply to keep warm air inside your house, this isn’t necessarily true. What insulation actually does is slows the transfer of heat, meaning it can help in both the cold and warm seasons—a properly insulated attic will retain heat in the winter and keep heat out in the summer.

There are plenty of ways to tell that you need new attic insulation. Here are a few signs:

  • Drafts through the home: A leaky attic will bring significant drafts into the home. Not only can this be uncomfortable, but it will result in your conditioned or heated air being lost.
  • Higher energy bills: Speaking of air loss… Whether the bills are getting higher or you suspect they’ve always been too high, upgrading your insulation could show a nice reduction in your monthly energy costs.
  • Older Home: If your home is more than 10 years old, you’ll most likely need more insulation.

2. Dealing with Faulty and Dirty Ducts

The ductwork in your home is responsible for moving large volumes of conditioned air all of over your home! And without it, your air conditioner would render quite useless. So, when your ductwork system becomes dirty or damaged, it can severely impact your cooling efficiency. In fact, 30% of the conditioned air can end up escaping through breaches in the ductwork, which means that it’ll never end up reaching all the spaces in your home.

To combat this issue, it is important that you schedule regular ductwork services, including ductwork repair and replacement and duct cleaning services.

Hire a Professional

Of course, the last thing you want to deal with is AC replacement, so it is important that you invest in the services designed to keep your system running efficiently and effectively for years to come! Hiring a professional to handle your attic insulation and ductwork services is a great way to keep your AC in tip-top shape!

Q & A with Red Seal Journeywoman Liz Sandwith RSE

We asked Red Seal Journeywoman Liz Sandwith of Black & McDonald to answer 4 quick questions about her experience working in the HVAC industry. Read on to learn the universal reasons why she loves the world of HVAC and get her unique perspective as a woman working in this industry.

1.  How long have you worked in HVAC?

I made a career change in 2014 and went to school 2014/2015. I started my apprenticeship June 2015 and completed it February 2019 and am a Red Seal Journeywoman (the very first and currently only one so far in my province for Refrigeration/Air Conditioning Technician). I have worked in Commercial/Industrial HVAC for the same company since 2015.

2. Why do you love what you do?

I love the sense of accomplishment when I repair something!! I love being up on roofs and seeing views that only a very few people get to see. I love being an example to my sons of what a woman can accomplish when she puts her mind to something and breaking stigmas. I also love the financial freedom that this trade gives me. Pay equity is important (I work for a National Unionized company).

3.  As we talked about in our post Women in HVAC women are severely underrepresented in the HVAC industry. Do you have any advice for women thinking about getting in the field?

If at all possible see if you can shadow someone for a little while as a helper to make sure you want to commit to training. It’s not an easy job, lots of stress and responsibility, you work in all kinds of weather and are on call at times. Shadowing really made me understand how hard the job is and also how rewarding it can be and just to make sure heights/ladders and things like that don’t bother you. Then don’t let anyone stand in your way. Women are different than men, yes, but we are strong and capable!!

4. Did you have any woman mentors in the field?

No, I didn’t have any women mentors but there are lots of ladies killing it on social media and more and more groups supporting women in trades in many cities. Most women in trades are willing to mentor and help out other women. I have been very fortunate to have many contacts in the HVAC world in my city and have worked alongside lots of men that are very supportive and have been my mentors.
