"My neighbor and I share a furnace room. A couple of days ago, Kevin from Genove was doing her annual service and noticed that the boiler for my baseboard heating had a slow leak. He shut it off so that it wouldn't flood our basement and notified me of the problem, explaining it in detail so I could tell my oil company what was wrong when I called them for emergency service. Thanks to Kevin noticing a problem in equipment he wasn't servicing, we avoided major damage."

"I looked at a number of different options and they had the best pricing and they also specialize in just doing central air. So they were also sort of a plumber and gas fitter, anything like that, and so they really specialized in what I was looking for. So that is sort of their core business. They were good and they did a very nice, clean job. The house was built in 1901 and so they did a great job of removing the old radiators and radiant based heat systems and replacing it with a new central air set up."

"Everclear called near immediately upon my query through Angi. The technician came out within a few days, was very prompt on the scheduled appointment and took care of my dryer service. They were very reasonable in my opinion and would highly recommend them on all counts."

"We've used Atlantic Heating & AC for many years and wouldn't consider any other company. Atlantic is extremely responsive, priced reasonably, and they always do a great job. We've never once had to call them back to resolve any issues associated with their work, and they've done a lot of work over for us over the last 9 years. Recently, our water heater died very suddenly; I came home from my office and water was leaking out of the water heater onto the basement floor. Within minutes, their service manager was guiding me over the phone regarding which valves to turn off etc. and he had me take a few pics to send to him. The very next day, a serviceman was at our house installing a brand new, much better water heater than the house had come with, and we haven't had an issue yet, and this was several months ago. I'm a Realtor and Atlantic has bailed my seller clients out of HVAC issues on a moment's notice, so I will always be grateful for the excellent sales and service that we receive thanks to Atlantic Heating and AC."

"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!"

"Never having had to hire someone to fix my AC unit only to install it (and the company was not reputable), I had serious trust issues. Action was the only one to contact me of all the suggested companies. That made me even more suspicious! They were able to fit me in for the next day. Hmm, more hesitation. But I rested in Action's good reviews on HomeAdvisor and kept the appointment. I was so happy I did. Mike was fantastic. He was personable and extremely informative. He knows his AC and heat pumps really well. I look forward to having them back in a couple of weeks to clean my furnace and do some cleaning and troubleshooting on a Hearthstone gas fireplace. When one finds a company one can trust, well, stick with them and get what needs to be done, done. I am so happy to have done something so out of my nature, like trusting HomeAdvisor. Thank you, Action Plumbing, Heating, and Airconditioning!"

"Thank you Saul from Revolution. Saul was very accommodating with meeting us for a free estimate after hours so I didn't have to take time off work. He was also accommodating by completing the install on two new furnaces on my day off. I look forward to having ac units installed on the furnaces in the spring. I am very happy and would recommend Revolution HVAC to anyone looking for HVAC services. Saul showed up on time and it was a pleasure dealing with him. This is the second time I used Revolution for heating needs. A++++++ services."

Heating and Air Conditioning questions, answered by experts

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
