"Highly recommended and I will be calling next time I need help. My heater wasn't heating so I called around. Dylan was able to come straight over, less than 2 hours after I called the house was warm. Luckily it was a simple fix, no parts needed (a spider had built it's web in there), so the whole repair was covered under the $89 service fee. Dylan was respectful of me and of my home. AND he told me they work on swamp coolers, which is sort of hard to find these days."

"So happy with my new furnace! Habib was super responsive and squeezed me in right after our first cold snap, right before Christmas. Did a great job explaining things both about the new unit and the concerns about my old/broken. Very competitively priced. His whole team was professional and respectful. They left my place spotless after the install. Will be contacting ComfAir again when my 30 year old AC inevitably bites the dust! "

Heating and Air Conditioning questions, answered by experts

You should service your AC at least once per year, in the spring, and twice per year if your unit is 10 years or older. As your unit ages, more maintenance can catch problems early and help the system reach its full lifespan potential, usually 15 years.

Get on your HVAC technician’s schedule in early spring so your unit is ready to go for the season. If you’re doing two inspections per year, aim for one in the spring and one in the fall. You should also service your furnace once per year in the fall.

The first sign you're not getting enough return air is if some parts of your home feel hotter or colder than others. If nothing else is causing that, leaky air ducts are your next clue. If the air pressure feels different in every room, this is also usually a sign of insufficient return air.

AC capacitors last between five and 15 years, with an average lifespan of 10 years. Most people only need to replace a capacitor once during an AC unit’s lifetime. You don’t need to replace the capacitor unless something is wrong with it, which an HVAC repair pro can diagnose. 

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.
