"We found CLIMATE MECHANICS from their stellar reviews while searching for a knowledgeable and competent HVAC company. For years, we were dealing with a condensation problem with our LG mini split air conditioner, and no one could find the source of the problem. We can honestly say that we've never experienced a company like CLIMATE MECHANICS so committed to making things right. Nate, the awesome climate mechanic that came to our home, and Robert, the owner of the company, could understandably have walked away because they did not install the system and were not responsible for the problem. Nate worked for hours trying to locate the problem. In the end, after so many years of leaking, CLIMATE MECHANICS went above and beyond and resolved our ongoing problem. Toni, their wonderful contact person, told us repeatedly that Robert just wanted us to be happy in the end. And we are. Totally. Thank you Robert, Nate and Toni."

"Our furnace failed on a rather cold day. We called Arctic Air Conditioning and they sent a technician the same morning. The system was ~30 year old, and we know we needed to replace. Once we confirmed that the furnace is not salvageable, they sent an advisor, Chris, to do the measurement and gave an estimate. Chris was able to arrange the installation in 2 days. The team came and completed the work as expected. The work was done in about 5 hours: removal of the old gas furnace & AC unit, installation of new units and new thermostat. They made sure we inspect their work, and showed us how the furnace works. The AC will need to be fully charged when the weather is warmer. A couple things to know is that the utility rebate is small and not worth taking into purchase decision. The Lennox thermostat works well, but the phone app does not work (rated extremely poorly on app store), so don't bother. We picked the better upgrade, which is reflected in the project cost."

"I'm very happy with the work performed by this company plus the technician explained to me in detail of the work he was going to do as well as the correct way the dryer vent should have been installed before as the the exhaust vent was connected to the lower vent instead of the higher vent, saying that connecting it to the higher vent gave it more room for the lint to collect before it started clogging up the exhaust. The air duct cleaning was also conducted professionally and I have no complaint about their work. I would hire them again the next time my heating and cooling ducts needs cleaning. I'd recommend them to my friends."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

Air Conditioning FAQs, answered by experts

Your AC might not cool after a power outage because of a tripped circuit breaker, blown fuse, or damage to the compressor or capacitor. If you notice your AC not working after a power outage, in most cases, the breaker has tripped or the system has built-in brownout and blackout protection. Reboot the AC by turning it off at the thermostat, resetting the circuit breaker, and waiting 30 minutes to turn the AC on again. 

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit.
