"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!"

"Jarod was terrific to work with. He educated me on the HVAC systems he put in. He was efficient and communicated very well with timing of when he would be here and when he would be back. He cleaned up the areas he worked in. I am very happy with his work and highly recommend him."

Customers say: True professional

"Gary and Tina went well beyond my expectations. From a detailed explanation of the job upfront including pricing and finding a break in the duct work after they began the job. They visited 3 times (about 3 hrs r/t each visit) waiting for a hvac company to repair the duct work so they could perform the work previously detailed. Very professional, meticulous in their work and the house was as clean when they left as when they arrived. I will without hesitation call on them to perform their service in the future."

Heating and Air Conditioning questions, answered by experts

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.

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

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.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.
