What Causes the Most Common Heating and Air Conditioning Repairs?

What causes the most common heating and air conditioning repairs? HVAC technicians service thousands of home furnaces each year, and what they see is astounding.

• 60 percent of calls are for the limit switch breaches
• 30 percent of calls are for run capacitor issues
• 10 percent of calls are for miscellaneous conditions

The majority of these common heating and air conditioning repairs can easily be prevented. How? With good usage habits and a service necessary just twice a year.

60 Percent of Heating and Air Conditioning Repair for the Limit Switch

The limit switch, or the safety switch, is a mechanism inside the heating and air conditioning system. Its primary function is to shut off the furnace when it senses a dangerous situation. Typically, the limit switch flips when the furnace or air conditioner overheats. Once the limit switch flips, the furnace will not turn back on until the system is reset. This generally signals for heating and air conditioning repairs.

What causes these heating and air conditioning repairs? Heating and air conditioning repairs from limit switches often result from dirty air filters.

Air filters play an important role.

• They prevent heating and air conditioning repairs
• They protect furnace and air conditioner parts
• They improve indoor air quality
• They maintain energy efficiency

Air filters need to be changed every few months in order to remain effective. Homeowners are encouraged to learn how to replace air filters to avoid heating and air conditioning repairs caused by the limit switch.

30 Percent of Heating and Air Conditioning Repair for the Run Capacitor

Thirty percent of heating and air conditioning repairs are caused by bad run capacitors. These run capacitors are attached to the blower motor and their batteries have a tendency to spoil.

Homeowners can help reduce the likelihood of heating and air conditioning repairs for the run capacitor by keeping the furnace as clean as possible. Reducing dirt, dust and other buildup helps protect heating and air conditioning parts from repairs.

10 Percent of Heating and Air Conditioning Repair for the Circuit Board

The remainder of heating and air conditioning repairs is for miscellaneous issues like:

• Extinguished pilot lights
• Stalled blower motors
• Troubled circuit boards

These smaller issues don’t take long to fix and happen for a number of reasons. Most typically, these minor heating and air conditioning repairs occur from normal wear and tear, old age or technical hindrances.
