4 Reasons Your HVAC Heat is Not Working

If your heating system isn’t working correctly, call a professional to help repair your problem.

Making an emergency call to an HVAC technician in the middle of the night is often painful and expensive. The best way to prevent doing so is by hiring a professional to perform regular HVAC maintenance to ensure that things run smoothly. However, as any homeowner knows, things don’t always go as planned.

If you find that your HVAC system isn’t working correctly, there are times when it becomes necessary to call a professional to fix your problem. Before making that call, there are a few things you can check.

Your Filters Need to Be Changed

One common cause of HVAC heat not working is dirty air filters. Over time, filters can become clogged with debris, which can limit airflow and cause the HVAC system to work harder than it should. If you notice that your thermostat is struggling to maintain the desired temperature or your HVAC system is constantly turning on and off, checking and cleaning your filters should be the first step.

The Thermostat Isn’t Working

Another potential culprit for HVAC heat not working is a malfunctioning thermostat. If you are constantly messing with the thermostat and can’t get the room to the temperature you want, then you might want to consider that it isn’t an HVAC system issue at all. It might just be that your thermostat isn’t working correctly – or at all. Try replacing the batteries first to make sure that it has full power. Next, check to make sure that there isn’t an excessive amount of dirt and debris on or around it. If you can’t get it to work, replace it with an HVAC specialist.

The Pilot Has Gone Out

If you can’t get your heat to work, then the first place to research is to ensure that the pilot light hasn’t gone out. The pilot light should have an electronic ignition that you can see under the panel. If you don’t see a small flame lit, then it is likely that your pilot light has gone out and needs to be lit. If you light it and it goes out again, however, it is time to call a technician to figure out the problem. Since it is highly flammable, make sure you know what you are doing to ensure you don’t get hurt. Never take chances with gas lines – it is better just to call and have someone take a look than to risk injury.

Your System Just Isn’t Working

If you have tried all of the above, and your HVAC heat still isn’t working, it’s likely time to call a professional to diagnose and repair the problem. Trying to fix the issue yourself can be dangerous, especially if your system uses gas, so it’s best to leave it to the experts.

No one wants to make an expensive repair call if they don’t have to. However, if you troubleshoot the minor issues and find something minor, or you can’t find anything at all, then it is best to call in someone who can fix your problem quickly and correctly.
