4 Tips to Keep Your AC Running This Summer


Your home is more than just four walls; it equates to security and comfort for you and your family. When the outdoor temperatures soar, you’ll want to escape to a cool dwelling space. However, like all things mechanical, your air conditioning system is prone to malfunction without routine maintenance.

If your air conditioner has stopped working properly, try these DIY tips to troubleshoot potential issues.

Is Your Thermostat Malfunctioning?

If the temperature is too warm, your thermostat might be at fault.

The thermostat will display two temperatures: setpoint and room. The setpoint is your desired temperature; the room is the temperature of the space. When the room temperature rises to the setpoint, the thermostat is supposed to send a signal to the AC system to drop the temperature.

If your home is warmer than it should be, your thermostat may not be communicating with your AC as it should be. Try these tips to self-diagnose the issue:

  • Calibrate your thermostat. You’ll need to consult the user manual for instructions, as every thermostat is different.

  • Check the connections. Remove the cover to expose the wire connections. Does something look disconnected? If so, consult your user manual or contact our team.

  • Check the battery. Some thermostats are battery operated. When the battery dies, the display will go blank. The solution is simple: just replace the battery.

Is It Time to Replace the Filters?

Sometimes an air conditioner problem can be fixed by simply changing your air filter. A clogged air filter restricts airflow, compromising your comfort. It can also damage your central air unit.

As a general rule, you should replace the filter in your HVAC unit every 30 to 90 days. 

Is Anything Blocking Your Vents?

Make sure all the return and supply vents are unobstructed. Furniture, rugs, and drapes are common culprits of blocked vents.

Did the Breakers Trip?

Find your home’s main electrical panel. Hopefully, your breaker switches are clearly labeled. If the breakers to your AC unit tripped, switch them back to the “on” position.
