"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 called to make on appointment for an estimate to replace our 30 year old boiler. The appointment was on my day off a few days later. Mike showed up on time. He inspected the boiler and the house, asked questions about the house and what I wanted. Gave me advice on what I wanted to do. Mike e-mailed me three quotes a few day later, with specs on the boilers. Called me a few days after that to see if I had questions. I made the appointment for the install, again, on my schedule. Mike and his crew showed up on time. We went over what was expected, and his crew was off the the races. They removed the old boiler and installed the new boiler as promised. Mike and his crew were very professional at all times. Highly recommend Ethical Home pro."

"Palmer Gas & Oil just did an entire replacement of the 20-year-old central HVAC + humidifier + thermostats two-zone system in my home with a new state-of-the-art total system and I could not be more pleased. From start to finish each employee was personable, extremely knowledgeable, very courteous, and the consummate professional. There is truth to the adage that you get what you pay for and I know I got the best. All Gold Stars!"

"Patrick called Friday night and showed up at 7:15 AM on a Saturday morning (OMG) to repair a central A/C system that was icing up inside. I'm still waiting to hear from the other 2 companies that were listed in my area. I know they will call Monday which would mean myself and my disabled wife would spend a very uncomfortable weekend and probably longer because most HVAC companies don't work weekends and it usually takes at least a day to schedule an appointment. Not fun when the humidity is 65% and the temp is close to 80. Patrick did a great job, A/C is running like new. Will hire him again and recommend him in a heart beat. Prices are very reasonable. Hire him!"

Heating and Air Conditioning FAQs, answered by experts

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

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.

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.

The top reason to purchase an HVAC maintenance contract is the fact that it ensures you are detecting problems before they turn into expensive fixes. Secondly, this type of contract provides priority service, which is nice if it’s peak busy season. Finally, an HVAC maintenance contract provides discounts on parts and labor for repairs, which can save you a good amount of money if your unit breaks.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.
