"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."

"We installed a Fujitsu mini-split A/C and heat pump because installing duct work was not an option. The entire process from getting a quote to completing the installation couldn't have been any better. Joe went over the full scope of the project including the ramifications if any additional work was needed. I don't think one could find a better HVAC company than Airco!"

"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."

"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!"

"Saul called me very fast to set up a time for an estimate and came out quickly with Matt. Matt and Nick did a wonderful job installing my forced hot water baseboards for me. They are professional, polite, neat and thorough. I was skeptical about hiring a company off HomeAdvisor, but I am very glad I did. I HIGHLY recommend Revolution HVAC. These guys care about the customer and keeping their business reputation stellar."

"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

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

Your central A/C unit should be professionally serviced and inspected at least once a year to ensure it operates properly and efficiently. This is best done before the peak cooling season. A full-service inspection by a qualified pro will typically include checking safety components for issues like carbon monoxide leaks, verifying cooling components and coolant levels, and inspecting electrical parts like fuses and wiring. Regular servicing enhances efficiency, mitigates potential problems, and maintains optimal performance. Because AC systems contain hazardous refrigerant, professional handling is essential.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.
