HVAC Inspection

Summertime is here in Alpharetta, Georgia, and temperatures typically remain high. The last thing you want is for your HVAC system to constantly run without turning off. Not only is this frustrating, but it can also lead to higher energy bills and potential damage to your system. Why does your HVAC not turn off in the heat of summer? There are a few possible reasons to consider.

Thermostat Problems

It could be a problem with your thermostat. If your thermostat is malfunctioning or incorrectly calibrated, it may send the wrong signals to your HVAC system. This can result in your system running continuously, even when it doesn’t need to be. Try resetting or replacing your thermostat to see if this fixes the issue.

Also, trying to keep your home cooler than normal during high heat periods can overwork your HVAC system, causing it to run continuously. Try raising your thermostat a few degrees and adjusting to a slightly warmer inside temperature.

Inadequate HVAC System

Another possibility is that your HVAC system needs to be bigger for your home. If your system struggles to keep up with the demand of cooling your home, it may run continuously to maintain a comfortable temperature. Many multi-level homes may require a separate unit for each floor. In this case, upgrading to a larger system or adding an additional HVAC unit may be necessary.

Inadequate Maintenance

It’s also worth checking your air filters and exterior unit to see if they are dirty or clogged. When your filters are dirty, they can restrict airflow and cause your system to work harder. Grass or other debris can collect around your exterior unit and prevent the free flow of air. This can lead to your system running non-stop to cool your home. Regularly changing your air filters and keeping the exterior unit clean and debris-free can help prevent this issue.

Older HVAC System

How old is your home? It’s important to consider the age of your HVAC system. If you are still using the original HVAC system that was installed when your home was new, it is likely old and outdated; it may not be running efficiently. This can lead to it running continuously as it struggles to keep up with demand. In this case, it may be worth investing in a new, more efficient system.

Chris A.
I have recommended this company to everyone. They have a very professional staff, that are timely as well as respectful of your time and your home. Prices are very reasonable and the quality and service are amazing.
Robert B.
They came out right away and properly fixed my AC problem a month after the original AC company came out. Very professional and honest. They could have charged me double (which is what the original company did) and I would not have questioned it and would have gladly paid it. THANKS!
Keith S.
I generally don't post but will make an exception. ClimateSmith is the best HVAC contractor I've used in the 20+ years I've been in Atlanta. They installed a complete heat pump system and ductwork for a very challenging room to cool. Dependable, fair, honest, knowledgeable..highly recommended!
