Homeowners often take their HVAC units for granted. They set the thermostat to the desired temperature and expect the HVAC systems to work efficiently and effectively. However, many fail to realize that weather can greatly impact the performance of HVAC units. Can weather impact an HVAC exterior unit? If so, how?

ClimateSmith, LLC, is your neighborhood residential HVAC maintenance and repair specialist serving clients in Alpharetta, Milton, Cumming, Roswell, Johns Creek, Crabapple and the surrounding areas. Call us with your questions about home or commercial HVAC units and systems.

Hot Weather

Let’s start with the impact of hot weather on our HVAC systems. On a hot day, our air conditioners work hard to cool our homes. This increased workload can put a strain on the HVAC unit’s compressor, causing it to overheat and potentially burn out.

To avoid this, it is important to keep up with regular maintenance, including changing air filters, cleaning coils and scheduling annual tune-ups. Additionally, homeowners can reduce the workload on their air conditioners by using ceiling fans, closing curtains or blinds to block out sunlight and setting the thermostat a few degrees higher than usual.

Cold Weather

In contrast, cold weather can also impact our HVAC units. When the temperature drops, our heating systems work harder to keep our homes warm. This increased workload can cause wear and tear on the HVAC unit, leading to breakdowns and malfunctions.

To prevent this, homeowners should again keep up with regular maintenance, including cleaning air filters, checking for leaks or cracks in ductwork and scheduling annual tune-ups. Additionally, homeowners can reduce the workload on their heating system by ensuring proper insulation, closing off unused rooms and using a programmable thermostat to regulate the temperature.

Extreme Weather

Extreme weather conditions, such as thunderstorms, hurricanes and snowstorms, can also impact our HVAC units. During these weather events, power outages and surges can damage the HVAC unit’s electrical components, leading to costly repairs or replacements.

To protect against this, homeowners can invest in surge protectors and backup generators to keep their HVAC units running during power outages.

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!
