"I am a long time customer who pays Rodenheiser a monthly fee which covers annual maintenance and some priority in the event of any necessary repair required. I had an a/c compressor failure. I had to wait 3 weeks to have a technician visit and tell me that the unit’s motor was dead and the compressor needed replacement. Then, after ordering a new compressor, which was available within 3-4 days I was scheduled for an installation 3+ weeks later. I had to complain strenuously and threaten to cancel the order to get the installation moved forward to within 10 days. Apparently being a long time customer and paying a monthly fee for better service means absolutely nothing. The installation went well. Not sure about future relationship."

"Two men, Jerry and Tommy, arrived on the morning of May 19, 2017 to install the system. Tommy dug a hole on one side of the house, poured a concrete foundation in said hole, and also set up metal tubing, which created a stand on which the condenser sits to protect it from runoff. Meanwhile, Jerry was inside, drilling holes through my bedroom and dining room interior and then exterior walls for the refrigerant pipes which run from the condenser to the air handlers. He mounted each air handler high up on the wall. There was also electrical work performed to connect the units to the main panel in the basement. The whole job took several hours. Both men worked quickly and efficiently. At the close of it, Jerry presented me with my remotes and instructions, and showed me the basics. I used the system for the first time just a couple of nights after installation. The first night (it was the start of a heat wave) the air from the system was cool-ish - tolerable, but not quite as comfortable as I'd hoped - but I was still uncertain about the controls so I didn't tab down the temperature. The second night I did tab down the temperature, and that's when I found out that, though the fans and vanes in both air handlers worked, the cooling mechanisms did not. Considering the amount of money I'd just spent i was more than a little upset. Visions of law suits danced in my overheated head that night. I called the next morning. Jerry came out that day and diagnosed the problem (something to do with the solenoids, or maybe it was the thermistors). In any case, he did fix it, and this time, it worked as designed, and has done so ever since. I should add that NETR offers a service contract. Despite the added expense - for me, 234.99 a year for 3 years (the annual rate is fixed for that period, plus I get a 5% discount) - it makes total sense to have this complex system undergo periodic maintenance. I will pay the total at the time of the first inspection, in 2018."

"Replied quickly, had lowest quoted price (significantly lower than my other quotes), did a really nice Roth tank installation in a tough spot, did NOT price gouge me for some extra piping that was needed, on time, cleaned up after work was completed. Solid A rating from me, I would recommend his services if your in need of an oil tank replacement or upgrade."

"That was the second time we used them. It was about a year before. We have our chimney cleaned usually once a year. I want to say it was less the first time but I think maybe we had some special coupon. It might have been about $40 or $45 less, possibly."

"Our heating system is older, and this was not a common job. Peter conducted the necessary research to make our steam system worry-free. The communication and customer service were excellent. Peter and his partner were conscientious of not tracking in dirt and snow and cleaning up their work space. They were also wonderful with my chatty three year old. Peter's knowledge and advice made me confident in the work he performed and has made him our new plumber for future needs. Best of all, Peter's prices were quite reasonable. I recommend Zereski Plumbing without hesitation!

"Sila Heating and Air Conditioning is the only service I found that can service my Buderus oil burner. John was the tech this time and he did an excellent job of taking care of the burner and then explaining the problem that arose with my chimney liner. Since I didn't have heat or hot water until the liner was fixed, I had to use a company I didn't know as an emergency repair. I was able to speak with their tech using the information provided by John and therefore felt comfortable with the costly repair. John even came back after his last call to turn the burner back on. I have the warranty on my burner so I pay a discounted price and have the coverage if I need it."

"Working with AccuTemp (and specifically Damon) was extremely easy! I called on a Sunday because my forced hot air system had stopped blowing warm air and, with children in the house and the temperature dropping, I needed assistance right away. Damon first talked me through what some of the issues might be, then gave me my options for how I would like to proceed with fixing it. At no point was he ever pushy and he provided me with all of the information that I needed to make an informed decision. Damon came out later that evening, fixed the problem in about 30 minutes and even gave us information about how we could save money on the repair by signing up for a service contract. I would be happy to recommend AccuTemp to anyone who needs HVAC assistance."

FAQs for swamp cooler service or repair projects in Millis, MA

A well-maintained swamp cooler can last between 10 and 15 years. Its longevity depends on usage frequency, water quality, and proper care. Regular maintenance, like winterization and protective measures, can preserve your system's efficiency and prevent premature breakdowns, ensuring reliable cooling performance over its lifespan. Hiring a professional to take care of any repairs over your swamp cooler’s lifespan will ensure it’s restored to proper functioning and can help it last longer.

You should consider replacing your swamp cooler if it shows signs of severe corrosion, inadequate maintenance, advanced age, restricted airflow, or ongoing leaks. When repair costs and performance inefficiencies make restoration impractical, replacement may be the best option. Evaluating these issues with a professional ensures you choose the most effective solution, preserving comfort and cost efficiency while avoiding further deterioration of the system.
