"Excellent communication from Keith; outstanding service from Roger. Professional, timely, and reasonably priced. They came in under estimate on my boiler repair and advised that a second bit of work that had previously been discussed was not going to be necessary. I will definitely use them again and highly recommend them!"

"Bill was willing to install a heat pump system that I purchased, even though his default was Bosch. His son and helper did the install over two days. It was getting late when they finished and the unit worked, although it whistled. I let Bill McGinley know but couldn't get them to come out to resolve the problem for over a week. Bill figured out that air was being sucked in between the top bottom front panels on the ACIQ central unit and did a workaround -- taping over it. The manufacturer ACIQ was no help in acknowledging that there was a problem with their product. I made a mistake paying on the basis of the quote rather then requiring an invoice. When I tried to apply for the NHSaves rebate, they wanted an invoice. Bill was not very responsive in sending me the invoice. He did when I told him NHSaves would be contacting him. But he was very accommodating in doing the work i wanted done instead of doing what he was used to doing."

"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 received a response within 15 minutes and scheduled service call right away to fix nonworking furnace. Arrived 20 minutes earlier than scheduled and diagnosed and repaired furnace within a half hour. Everything up and running quickly and totally satisfied with the service. Will definitely use for any future needs and absolutely recommend Minuteman if you are in their service area."

"Rd.I had to pay an extra $15.00 because I had an extra air duct or intake vent. He discussed how often the ducts should be cleaned and offered another service that would help disinfect and keep dust mights down. The extra service also extended the length of time before I would need to have the vents cleaned again. I chose the extra service and will not have to have it done again until 8-10 years from now. My nephew who is 45 was not happy I was having the ducts cleaned but he was pleased with their work in the end. I had this done in my last house twice so I am not new to this. I was pleased with their work. They started immediately and finished about an hour and fifteen minutes later. I have house that is almost 2,000 sq. feet. The $230.00 includes the $89.00 I paid when I ordered it through Angie's List.

"The service was handy when my oil heat quit over a Saturday night. Many other potential responders were closed for Sunday, and it was important to find help for my emergency. Dale was prompt and professional. Due to his contacts, he was able to obtain the part we needed and finished the job with the one visit. I am very happy with the service and grateful for Dale's professionalism. Highly recommended!"

"Called Hudson Heating and spoke to Gill. He was super nice and told me a couple of things to try since I am a bit of a handyman. What he told me over the phone fixed the problem and saved me a service call. You don't get people like this today. He could have taken advantage of this situation and come out for a service call. I really appreciated what he did and I will use Hudson in the future for any and all of my needs. I highly recommend Hudson and Gill."

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

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