"Joyce Cooling and Heating installed a new high-efficiency Lennox furnace and air conditioner. The installation looks great and was professionally completed. The furnace is working fantastic and is so quiet we can't even hear it running. We are warm and comfortable all the time and the new high-efficiency design should save us money for many years to come. The technicians answered all of my numerous questions."

"We had a leaking 35 year old oil-fired boiler that needed to be replaced. This was just at the start of the heating season in 2021. We got quotes for price & installation dates from several HVAC companies Clear All HVAC supplied several boiler replacement options and also quoted an earlier delivery date than any other quote. We selected a boiler/indirect water heater combination that was significantly less than competing quotes. Clear All installed the system within a week and responded quickly to any concerns & questions we had. We highly recommend Clear All HVAC for anyone that needs HVAC installations, repairs, service and values good customer service. In our opinion they are outstanding and we will continue to use them as our go to HVAC Services company."

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"They cleaned my dryer vent. There was a lot of disassembly involved because there was an auxiliary fan involved due to the long run to the outside of my unit. They were very efficient and cleaned up all debris afterward. I will use them again."

"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

Heating and Air Conditioning questions, answered by experts

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

Trick question: There is no difference between an AC and a furnace blower motor. Whether you have central air and heat or just one of these, the same blower motor carries hot and cold air throughout the ductwork in your home. Certain systems may have separate blower motors for the AC and furnace, but each serves the same function.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.
