"Smart Heating and Air Conditioning was very responsive and came out when we really needed them. We were without heat as our old furnace no longer worked and our AC was on its last leg. Mike came out to give us a quote which was the best out of three that we had. He went over all options with us and now we are very satisfied to have a new and efficient heating and AC system. They lived up to their name as well, by upgrading my thermostat to a WiFi one that added that SMART touch to my system."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

Heating and Air Conditioning questions, answered by experts

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.

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.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.
