"Decided to give MSD a call as I had another company over the house today to fix my AC and they were not able to repair it as they needed to order parts. Mehmet answered the phone and couldn't have been more professional/helpful. He spent 10 or so mins on the phone with me trying to understand the problem and give me advice. He unfortunately couldn't send some one out as he was super jammed with the current heat wave. I will not hesitate to call Mehmet again as he is a true professional and very knowledgeable."

"I'd become increasingly concerned about the company I was using for my AC and heating needs. When I knew we needed a lot of work doing, I decided to search for a new company that I could trust. We needed to get 4 new AC units installed. They were 17 years old and leaking, so we took the plunge and decided to replace them. I had a lot of questions around the systems in my house and what to install. During my phone conversations Donny was extremely helpful and patient. He answered all my questions and I believe that he gave me honest suggestions on the best solutions for my home and living situation. I found him to be honest, trustworthy and very knowledgeable. The install went smoothly, one of the units was tucked away in a tight closet in my daughters room, and they dealt with that easily. They installed 4 new controllers. They were tidy, and worked long hours to get the job done. In addition they spent time explaining the new systems to us and answering questions of ours that arose. We are really pleased with the new systems and controllers, we have peace of mind that we've installed good, reliable systems, and that we have a great company looking after our AC and heating needs. I also hired them to do annual service visits for our heating and AC. So far they have performed the winter maintenance visit, and identified a couple of things that needed addressing to prevent possible problems this winter. What they recommended made sense to us, and we thought they were valid and worthwhile repairs. As we trust this company, we decided to go ahead and get the work done. Chris D came to do the repair job. He was very friendly, helpful, hard working, and did a great job. He also took time to make sure we knew what was going on. I'm hugely relieved that I found this company. It's increasingly rare to find companies to help out in the home who are good at what they do, honest and trustworthy. I highly recommend them. BTW I'm also impressed with their office support staff. They are super friendly and helpful, calling back when they say they will. Booking appointments is super easy with this company."

"Inspection and work performed was extremely thorough, well communicated throughout the job so I could understand the status and look to the future of our units. He also allowed me the opportunity to look at what he had done, and what the duct cleaning company had or had not done. Specialist (Dennis) offered me a very reasonable service plan for the season that seemed very good value and which I paid for."

"I was always called a "valued" customer by their people. No wonder, I finally got around to shopping for oil and found a local reputable heating oil supplier and service for slightly over $1 less per gallon! Service was fine but given what I now have I was paying far more for EQUAL service. This is a large conglomerate of bought up oil companies. Not even local to me."

"I decided to go with Cassidy because out of the 4-5 different companies I contacted, they were the first to respond in a timely manner and their dispatch fee was affordable ($79 vs >$100). The actual service they provided went well. They were on time, finished the whole project within a couple hours and were professional. However, I did remove a star from my rating because they do overprice everything. I was able to cut down my total cost by >$300 by just buying my own supplies (ex: water faucet, basket strainer, faucet aerator, etc.). They were going to charge me $125 for something I was able to get for $4 and fix on my own, which I thought was ridiculous. Overall, I would recommend because they made the whole process go smoothly but I would just be aware of their pricing and make sure they don't trip you off."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

"I feel confident in Ryan and Sons’ knowledge and expertise in caring for my 250-year-old house. They have serviced my water softener, hot water heat, furnace, as well as performed other services that come up in an old house. Their communication is excellent, sending emails and calling so I know when to expect them. With a service plan on my water system, I get a discount on other services , too - you can’t beat that! Highly recommend!"

"We used Schede to replace our central air conditioner. Overall, we are satisfied with the new system and the price but the customer service was not satisfying. I think they did everything we needed in terms of the mechanical work. But they should better train their office help. After we agreed on the installation date, I asked what time the crew would arrive that morning. They gave a vague answer so I asked again the next day. But they arrived two hours later than expected. After they were done, we discovered that we needed a minor adjustment and scheduled a time for them to come. An hour after they were due, I called and was told they were not coming that day. The next day was the same ? I called after they were overdue and was told they were not coming that day. They finally came the third day. The technician solved the problem and was apologetic. But it was quite frustrating that they did not come as scheduled and did not initiate the call to say they would be late or there was a problem."

FAQs for central a/c service or repair projects in Danbury, CT

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.
