Before Calling for HVAC Repair, Check These Possible Issues

Even though it pains us to say it, not everyone loves having to call the heating and cooling repairman. In fact, we’re pretty sure no one does. Instead of crying into our AC drain pans though, we’re going to tell you something you want to hear: that phone call is not always necessary. There are more times than we can count where we get a call, arrive on the job, and the fix is something the homeowner could have easily done themselves. Before you call for HVAC repair, look into these 8 possible issues that may be affecting your system.

  • Is your refrigerator running? No, seriously, is it? If it’s not, then it could be a sign that your power is out, which could also be affecting your air conditioning. Check the electricity to ensure that the power supply to your house is on and functioning properly.
  • What about the gas meter? While you’re checking the electricity, go ahead and ensure the gas meter is turned on. This happens sometimes with new homes, or when people have just moved in.
  • Have any circuits been tripped? Take a look at your breaker box to see if any circuits have been tripped; if so, reset it. If the circuit continues to act up, you may need to call an electrician to check out the wiring to the panel.
  • Check the air filters. Your system is equipped with air filters that need regular changing. If it’s been awhile since you changed the filter, chances are it’s dirty and is now restricting air flow to the units, which will negatively impact heating and cooling in your home.
  • Is the thermostat on? Sometimes HVAC problems can be attributed to a simple dead battery situation in your thermostat. If the display is blank, swap out the batteries and see if that solves the issue.
  • Make sure your thermostat is set to the proper function as well, as it could have been accidentally switched to heating or cooling. Also, ensure that the temperature setting is where it’s supposed to be.
  • Take a look at the condensation pump and AC drain line. Most AC units are equipped with a safety switch that will stop the unit from operating if there’s a damaged drain line. Check the water pan underneath the unit to see if it’s holding water; if it is, there may be a clog in the drain line. Flush out the line and see if the unit operates normally after that.
  • Overcrowding around the unit. Take a look at the unit itself to ensure it has adequate air flow around it, and that something isn’t interfering with the ventilation around the machine. For outdoor AC units, make sure dirt and plant debris hasn’t found it’s way inside, and blow anything you see out.
