"I actually had two services completed - The installation of a heat pump and a new water heater. They arrived right on time and completed both jobs in a day. Jesse and Jonathan did an excellent job. This was a 3rd-floor condo unit so the outside unit was on the roof of the 5th story, I could not have been more pleased with the outcome - a very professional and thorough job. They even relocated the thermostat to a better wall location. Very easy to work with and the most important thing to me was they obviously take a lot of pride in their work and it's always a pleasure to deal with people who do what they say. Highly Recommended!!"

"Really amazing job. They stayed longer than the intended timeframe, to make sure everything was scrubbed down (even in hard to reach areas, etc). They also were very reasonable. I had to insist on giving them more than they were charging, because of the extra time they spent on the job."

Heating and Air Conditioning FAQs, answered by experts

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.
