"Very quick response time from my initial contact through Home Advisor. Came out and evaluated my split-type air conditioner which was at it's life's end. Gave me a fair and complete quote for the job and completed the system replacement. Very knowledgeable, tested the system fully before leaving. I will continue to use this company for scheduled maintenance and any issues that arise. I would recommend this company."

"I had originally thought that a high velocity mini-duct central a/c system was the only option for my Victorian home with baseboard heating. But when Joe Carnevale from Airco explained the benefits of a multi-zone slim-duct system with concealed air handlers in the attic to cool the second and third floors and a conventional system tied to existing (unused) floor registers on the first floor, I was intrigued. After rebates and tax credits (which aren?t available for high velocity systems) the cost was extremely competitive and the fact that the system has four individually controlled zones means that I can adjust the cooling levels to keep operating costs lower. The installation was a little tricky as I asked (owner) Steve Duarte and his crew to run the refrigerant, electrical, and condensate lines through an unused chase to the second and third floors rather than affix a conduit to the outside of the house (which wouldn?t have been allowed due to my home?s historic designation.) The work was done efficiently and with practically no disruption to the day-to-day living that went on during the installation. The left the house and basement very clean. I have been very satisfied with the system?s performance during the several heat waves we?ve experienced this summer. All in all it was a very professional job from start to finish and I would highly recommend Airco Home Comfort Services to anyone considering central air conditioning, and in particular to owners of older homes without existing ductwork.

"I have been a Palmer customer for 5 or 6 years at least. My experience with the front office and the technicians has always been great. We have always been on automatic oil fill and we have never had an issue. My most recent experience was today - we needed a service and a replacement part. The technician was very polite, experienced, knowledgeable and respectful of our time (David). He also had a more junior team member with him (Domenic) who was very respectful as well. I continue to be impressed with Palmer and will remain a customer for the foreseeable future!"

"Keith did a great job. Very professional, right on time, got the job done fast and done right at a very competitive price. Took the time after installation to show me the job and explain the features of the water heater, and also gave me information on how to properly maintain the unit and other services he offers. I would strongly recommend anyone consider Keith's services."

"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"Talked to Matt the owner one very hot Sunday in June when my A/Cs were not working. I had my regular folks tell me it was shot and had a leak. Matt sent his team out on Monday and the A/Cs were up and running in about 40 minutes. There was no leak. They worked beautifully all summer. My neighbor's went out this year - her unit was about 5 years older than mine. I gave her NextGenAire's contact info and she just replaced her unit. She is very happy with the price and service."

"The water pump for my over 16 year old central air conditioner stopped working and, as a result, I discovered water in my basement. I searched Home Advisor for a company to fix the problemand selected NSHEC based on customer reviews. I was able to schedule a service call online for that afternoon, then had a few questions about the issue and repair that I wanted answered before having them come out. I called and left a message, they returned my call within minutes, discussed my issue, explained what the possible issue was, how long it would take to fix it as well as the estimated cost of the repair. The technician, I believe his name is Jake, arrived on time and had the part on his truck. He quickly made the repair, explained what he did and that it is common for the these pumps to eventually stop working. If that should happen again in the future, the new pump was wired to shut down the ac and getting water in the basement would now be averted. The final cost was a few dollars more than the phone estimate, service was very prompt, the technician knowledgeable, quick, very pleasant and answered all of my questions before and after the repair. I wouldn't hesitate to call NSHEC again should another issue arise in the future."

FAQs for central a/c service or repair projects in Exeter, NH

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
