"These guys are great. They came to assess the situation (problems with our oil furnace) and thoroughly reviewed options. We went with them for a furnace replacement, as well as a heat pump to replace our standard a/c units. They came in much cheaper than the two other companies we consulted (one of which we had used for almost 50 years (since the house was new). We're thoroughly happy with our new HVAC setup, and even the fancy Nest thermostat. Highly recommended!"

"Sila installed a new Lennox HVAC system 2 years ago and when there was a leak today they showed up within hours! Not like some places that would have many excuses and complain about Fri being too busy. Their Tech Calverton is a special tech, knowledgeable, polite and willing to go the extra mile. Not only did he fix the leaking problem he took his time to adjust dampers to ensure all rooms are toasty! This has always been a problem for us and not fixed until now. It takes a patient problem solving tech to make a happy customer! A special thanks to the service manager ,Doug Bines , who always seems to help when needed."

"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."

"They installed central air conditioning in our house. They gave us the best price for what we wanted. Their installing technicians were extremely careful, clean, helpful and quiet. They installed a whole house  (2 floors) system with 12 registers in 3 days. The air handler was installed in the attic and compressor was installed outside. I would recommend them to my best friend and I would use them again if I move to another house."

Heating and Air Conditioning questions, answered by experts

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.
