"A great experience from start to finish. I found Kingdom Cooling on Angies List and the owner (Gerry) was very responsive and personable and explained to me in detail what he thought was going on after explaining the problem. He was able to give me a very accurate ballpark estimate which was very reasonable. Scheduling and timeliness of the repair was also done very quickly and efficiently. I would definitely recommend Kingdom Cooling for Service for sure!"

"Palmer Gas has been providing our homes with propane gas and services for over 25 years. The office and customer service staff is courteous and helpful. The installers and repair personnel show up on time and leave the area they are working on cleaner than it was when they started the work. The technicians and repair staff explain what they are doing in a very understandable way. That is important for this of us that are not mechanically oriented. I would recommend the company and staff for your propane needs."

"Many people complain about too expensive, but I believe you get what you pay for. Yes I could have picked cheaper but I researched the furnace they recommended, Amana, always in the top 5. When the installation was done I was surprised to find items not included with contract were repaired with no comment. Their service, maintenance and equipment are 5*"

"This was a service call for a annual tune-up/inspection of my boiler and water heater. Great communication from the beginning. Andrew, my primary contact, was the first vendor to reply with a quote, which I thought was very reasonable, and NRG had great reviews on HomeAdvisor, so I booked the appointment. The technicians (a two-man team) arrived on time within the specified window, and were extremely polite and very personable, and they even put on those shoe covers so they would track any debris into my basement. The service was completed in about an hour (no issues), and they were more than willing to answer my questions. I went through the "checkout" procedure right through one of their tablets (paid by check), and I had my receipt emailed to me before they even left. The final cost was the price that was quoted. They were efficient, very easy to deal with, and very professional. I would definitely utilize their services in the future, and would recommend NRG to friends/neighbors. Overall, a very good experience - thanks, NRG!"

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