"Kason is truly the best. Not only does he answer every time we call for any issue, but he or Connor, show up the same day which is huge when you run a small business! We needed a walk in freezer repair at our catering business- Kason was there on Wednesday to investigate, called me the same day with an estimate and we had the install on Friday. He is meticulous, precise and very knowledgeable. Kason has checked in the last few days to make sure things are still running smoothly and the freezer is doing its job- where can you find better customer service? I know we are a CRS Mechanical customer for life now."

"Kyle is always quick to respond and come out to evaluate, even after hours! He never lets us go without heat or hot water, if he can help it, and for that I am extremely grateful. He is also very knowledgeable in the field of HVAC"

"I am writing to express my deep disappointment with the service provided by McGinley & Sons. Despite multiple attempts to resolve this issue, I have yet to receive the promised refund for work that was never completed. As a cancer survivor undergoing surveillance scans, the refund would greatly assist in covering my medical expenses. The lack of response and follow-through has added unnecessary stress during an already difficult time. In addition to this, I had to hire a lawyer to recover my down payment, which cost me additional money. Moreover, he did not offer to compensate me for the extra expenses, including hiring an electrician to install a wire for the heat pump he could not install. Despite repeated attempts to have the deposit returned, I finally received it after engaging legal assistance. I hope this review will encourage McGinley & Sons to address this matter promptly and fairly."

"George at All Good Services Answered all my calls and text showed up at exactly when he said he would on New Years Eve and didn't rush through the job. He diagnosed the problem and fixed it. I'm totally grateful that he helped me during a tough situation. I would recommend his services to anyone looking to get their heating and cooling needs. A+ for customer service, knowledge and personality."

"While we didnt hire them, the company contacted us right away and were available within an appropriate timeline. The coordinator was friendly and reassuring and had we not had someone lined up I would have felt very comfortable moving forward with this group. They were transparent about their pricing and displayed confidence in their capabilities."

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