"Very knowledgeable owner-operator. Prompt and personable. He repaired our 30-year-old central ac unit and did not try to upsell us to a new one. He was very thorough in his inspection of our system. I will use him again when we decide to replace our ac."

"This was the best experience with a company that I have never had come to my home before. I run an Airbnb out of my residence and my central air stopped working in the middle of a heat wave. I called all the service people in my area and no one could come for 2 weeks. I was panicked! I found Cawiamca on Angi's list. They are located in Saybrook CT. I wasn't sure they would come all the way to my home in Mystic. The owner himself called me and had someone come out THAT VERY DAY!! And the problem was fixed within an hour. I can't say enough good things about this company and the service man that came out. Fabulous, friendly, and expert service! I highly recommend them!"

"Jeremy, the owner of Parker Home Services quickly - within hours - returned our request for service. He showed up early for the quote appointment. There was no BS. His quote was thorough and accurate. Jeremy removed and replaced the central AC units in a day and a half. His attention to detail is superb. Once the job was done, he brought me over to make sure that the AC worked as intended. While checking vents we noticed that some were not supplying air. Jeremy went back up in the attic and located three supply ducts that had been removed (by previous workers) from their registers and he reinstalled them. He also found a separate supply duct that had a board laying across it, constricting air flow. All of this was above and beyond what the initial job called for and shows that Jeremy takes great pride in his workmanship and making sure his customer is satisfied. We will have them back. Thank you PHS!"

"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."

"When I called a very professional receptionist listened to the issues and told me that Tim would contact me shortly.  Within ten minutes Tim called me.  We discussed the issues and possible causes.  I asked if he could talk to my landlord to discuss the work needed and get answers to questions that I was unable  to answer.  Within another ten minutes an action plan was determined and he was at the home within 45 minutes.  VERY courteous, prompt and got the problems fixed.  I could not have asked or wished for a better plumbing company.  My experience using other plumbing companies in CT (prior to joining this list) was typically frustrating and disappointing.  Thank you Tim. You are now on my Go-To list for anything plumbing-related.

"The repair person was very pleasant and professional. The quote to due the entire job was too expensive for my budget. They did a partial repair per my request which went very well. The primary job I had done by another licensed electrician at a more cheaper rate."

"They had to clean the gutters in 2 parts as some of the gutters had ice in them.  They were very quick and efficient both times they came and gave me a heads-up by telephone before they arrived just to make sure I was home.  They cleaned up all the debris afterwards.  Very happy with their service and would definitely use them again.

"CHW was very responsive to our urgent need! We filed a claim the evening prior when we notices our A/C was blowing warm air into the rooms. Then by 8AM the next day, we had a call from the service technician saying he was on his way to address the issue! CHW worked with the technician to find out the compressor was the culprit and approved it's repair! Great customer service for a family in need during the hot south central Texas summer!"

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