How To Troubleshoot Common HVAC Problem

No one can predict the time an HVAC system can break, but the winter months are the worst time to be without heat. Even the most well-maintained equipment can break down at inopportune times. 

You should do certain things to keep your HVAC system running smoothly and troubleshoot any problems that may emerge. Still, you should always call in the experts for routine maintenance and any necessary repairs. Agape Air Heating and Cooling are experts in heating repair, heating installation and ductless HVAC service in Gilbert, AZ and can help you with any of your HVAC needs. 

Common HVAC Problems and Their Troubleshooting.

Dirty Air Filters

This is a prevalent issue affecting the efficiency of a home’s HVAC system. Fortunately, this issue may be resolved with minimal effort. Changing your home’s air filter frequently is highly advised. A dirty filter may require replacement every month. This will depend on the air quality in your location and whether or not you have pets at home.

It is essential to examine the MERV rating on the filter, as there are numerous classifications. If the number is greater, air will be filtered through the material more efficiently. So contact us for the indoor air quality service in Gilbert.

An Improperly Operating Thermostat

If there is a problem with the thermostat or any of the accompanying remote control devices, it will influence the rest of the system. When your heater or air conditioner begins to operate inconsistently, you first should inspect the thermostat, as the solutions to this common problem are simple and inexpensive.

Given that batteries power many thermostats, the first step is to install brand-new batteries. If the batteries run out, the thermostat cannot communicate any information, including temperature changes, back to the system. It is conceivable that incorrect settings were entered into the thermostat during the installation which caused problems. So call the expert HVAC contractor in Gilbert, AZ to resolve your problem.

Pilot or Ignition Problems

There are several potential causes of ignition problems that may require heating repair or heating service in Gilbert, AZ. A dirty pilot, flame sensor, or burner can result in a pilot failure, short cycling, furnace lockout, or delayed ignition of the burners. It could also be due to a gas supply issue or simple wear and tear on an ignition component, such as the hot surface ignitor or thermocouple, that requires replacement.

It is in your best interest to have these problems fixed by a competent service professional, as they contain potentially hazardous elements such as high voltage and natural gas.

Blown Fuses or Tripped Breakers

The most common reason a furnace’s circuit breaker trips is the blower overworking. If something impedes airflow into your system, your blower must work harder to compensate. When the air filter is dirty, the blower must work harder to push air through the filter because the filter inhibits airflow. This increases the energy consumption of the blower and may occasionally trip the circuit breaker. 

Before resetting the circuit breaker, inspect the filter and replace it with a clean one. You can contact a competent expert for heating repair in Gilbert who will be able to safely determine if it is due to a problem with the furnace or whether the circuit breaker itself is to blame. Other issues that can cause the blower to overwork are duct leaks, closed or clogged air registers, and dirty coils.


Occasionally it’s easy to determine what’s wrong with the HVAC system, but it’s usually best to call professionals if it is unclear what created the issue or if the solution itself is difficult. Many problems that can arise with furnaces, air conditioning units, and heat pumps require extensive knowledge to resolve, and attempting to do so on your own may cause damage or even void the warranties.
