"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."

"I turned to finding a dryer vent contractor on this website when I was unsuccessful in finding one through Google. Either the company didn t call back or didn t show up. My current HVAC contractor stopped cleaning dryer vents. When I began the search, it was very late at night. Y&M Airduct Service phoned me the very next morning. They were rated very well and see why. They are honest and explain everything in detail. There were a few things I knew that needed to be addressed, such as the attachment to the hose behind the dryer and the vent that had been broken to the outside of the house. Everything has been fixed and/or replaced at a very reasonable rate. Not only was this experience very positive but have decided to not renew my contract with my exiting company that I ve had for over 10 years. I will be having Y&M perform all of my HVAC needs. If you decide to hire Y&M Airduct Service, you will have everything done right the first time. No hidden agenda, no hassle and piece of mind knowing one less item is taken care of."

"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

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

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.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Yes, a mini split AC system can replace central air—and quite easily, too. Since mini splits don’t require ductwork, homeowners can convert their central air system to a mini split to save money and energy. Consult with an HVAC professional to learn more about the process of replacing your central air with a mini split.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.
