My Central Heat isn’t Working, but the AC is… What Gives?

Updated: January 29, 2023

Most homeowners in Arizona appreciate the importance of having their HVAC systems working perfectly. Sadly, at some point, you may realize that your AC is working, but the central heat is not. You need to know that this problem is not unique to you. An experienced HVAC contractor can fix this problem but before contacting one of these repair guys, let us first look at the common causes of this issue, shall we?

4 Reasons Why Your Central Heat is Not Working

A Faulty Thermostat

You need to start by checking if your thermostat is powered and working properly. Try turning on the thermostat and adjusting the temperature so that your HVAC is turned on. If it fails to come on, check the circuit breaker and ensure that the switch is functioning properly. If you find that it had tripped, turn it back on. This should fix the problem.

Clogged Filters

The HVAC has coil air returns which help in filtering the air coming into your home. You need to clean these filters at least twice a year. However, depending on the usage of the system, you may need to clean the filters more than twice in a year.

Pilot Light or Igniter Problems

If your central heating unit uses gas or propane, then it is essential to check if the pilot light or igniter is operational. If you discover that the heat does not come on even after you have reset the thermostat, you should then shut off the gas and verify if you have gas, then reset the igniter. If you have gas and the igniter still fails to light after the reset, you should consider replacing the igniter or calling an HVAC repair technician to help check your central heating unit.

Poorly Maintained Furnace

It is common to find that the central heating stops working abruptly. This is often caused by the furnace detecting some problems which can easily be corrected through regular maintenance by an HVAC repair technician. Routine furnace maintenance is necessary because it will ensure that:

• Motors spin with no resistance
• The furnace does not experience too much stress
• The central air system stays in perfect condition and gives you service for longer.

We got prompt service when our air conditioner stopped working. Technician J.C. stuck around to investigate the issue and made sure our system was up and running. Very grateful to Howard Air and J.C. for exceptional service. Also we are grateful to Tanner who’s always helped us with our system. He called back make sure we were ok and I appreciate that so much!
