"Through the several steps of getting this generator project done Palmer was on time and on task always. Their communication is outstanding from Michelle's initial visit and proposals through tank delivery by Corey and most centrally through all of Steve's installation work and coordination with inspectors, electricians and me. Two weeks later first power outage and everything worked like a charm. I just started with Palmer four months ago and added oil delivery and service to my generator work and I've been pleased with everything in the office and field. Very grateful."

"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."

"Sunrise Heating and Cooling did an excellent job installing my new Rinnai tankless water heater/boiler. From start to finish, the experience was smooth and professional. The crew was knowledgeable, punctual, and took the time to explain the system and answer all of my questions. The installation was clean, efficient, and clearly done with attention to detail. Everything works perfectly, and I couldn?t be happier with the upgrade. It?s clear they take pride in their work. If you?re looking for reliable, honest, and high-quality service, I highly recommend Sunrise Heating and Cooling."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"I had a written estimate within 24 hours of my initial phone call to them for a complete HVAC replacement. The estimator arrived on time and made a point of first listening to what I thought I needed and what I wanted to get from my new system. He then gathered details of what was existing and came up with a proposal based on what was needed as well as my concerns. the installers were on time, they cleaned up extremely well when finished and the equipment looked great. They made a follow up call after a few day's to make sure all went well and asked if I had any concerns or issue. I did not. In my own job I manage 15 installers and technicians and I know very well what good customer service is. George's delivered by all measures and I would readily recommend them to anyone."

FAQs for central a/c service or repair projects in Greenland, 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.
