"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, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.
