"If you're looking for honest, dependable HVAC service, I can't recommend Blake enough! My central air unit was leaking and missing some hoses, and he had it fixed up in no time. He was professional, efficient, and took the time to explain everything to me. In a small town, word of mouth means everything, and Blake is the kind of person you want to support hardworking, trustworthy, and genuinely cares about his customers. If you need heating or air conditioning work done, give him a call. You won't be disappointed!"

"We had Jon M. with Presence Air install a whole home humidifier for us. He was very easy to get along with and helped us find a unit that fit our needs exactly. His work was quick and well done. Because of his recommendation, we were able to remove the four humidifiers we had previously used throughout our home. Couldn’t recommend these guys enough and will definitely be calling them for any future needs!"

Heating and Air Conditioning questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.
