What can you do when your HVAC unit isn’t working?

Everyone likes to think of themselves as at least a little handy, able to do a little DIY. However, not everyone is a handyman, and don’t worry, you’re not alone. Luckily, you don’t have to be a profession to try these 3 basic tips for troubleshooting your HVAC unit when it decides it’s quitting time (at least before you call for repairs).

1. Check the Basics First

Is there power to your HVAC unit? If not, that’s the first thing to check. Look for a blown fuse or check the circuit breaker. If it’s a gas furnace, check to be sure the valve is set to ‘open’. Also, check the pilot light.

2. What to Check if There’s No Warm Air

So there’s power to your HVAC unit, but there’s no warm air. Check the thermostat to be sure it’s set properly. Check the filter to make sure it’s clean and not clogged with dirt or debris.

3. Down to Some Nitty Gritty

Pay attention to see if you HVAC unit seems to be turning on and off too frequently. If this is the case, you should check the blower and be sure the oil ports are lubricated. Check the belt to be sure it’s in good condition and make sure it doesn’t need tightening.

If the blower is running constantly, be sure to check the settings on the HVAC unit thermostat to make sure it’s not set for the fan to be running continuously. If it’s not, the fan might need to be reset or replaced.

These are some basic troubleshooting tips you can do yourself if you’re having trouble with your HVAC unit. While some of these items are easy enough, some might be a little out of the ballpark for those of us that are not handy. If this is the case, the next troubleshooting step is to pick up the phone and call Helms Heating and Air Conditioning and have one of our expert technicians come to your home to assess and repair the problem.
