"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!"

"Bill was amazing from the start. Within an hour of submitting an inquiry through home advisor he immediately contacted me. Not only did he have questions but also provided minor troubleshooting steps to ensure it wasn't anything small causing my forced air system from consistently power cycling. Highly recommended."

"After another vendor recommended major repairs to a central AC system, so I called Parker Heating and Cooling to get another quote. Although I did not ask for a diagnosis, Jeremy inspected the system and discovered an overlooked minor problem, which he took care of. His diligence and honesty saved us thousands of dollars! Jeremy was very responsive and easy to deal with and checked back to make sure the problem was resolved. These days "five stars" has diminished in meaning, but this truly was excellent service!"

"I highly recommend ASL Mechanical! Austin recently replaced the compressor in my AC unit after I had an extremely frustrating experience with two other companies. One company did a poor job with the wiring and was unreliable with scheduling, while another recommended replacing the entire system?even though the unit is only four years old. Austin was a breath of fresh air! His professionalism, knowledge, honesty, and fair pricing were greatly appreciated. He took the time to properly assess the situation and provide the service that was actually needed. It?s refreshing to find a company you can trust. I wouldn?t hesitate to recommend ASL Mechanical to anyone looking for quality work and dependable service!"

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"The tech that came out was amazing and provided great service , the customer service people answering the phone weren?t very friendly , they mixed up dates , and never emailed things they said they would . The fact that the technician was so good was what saved them in my eyes. To be fair right now many companies are struggling for help and are forced to hire mediocre people they wouldn?t normally because people don?t want to work so I tend to give them a break on criticizing. If they worked on the clerical end they would be an all around solid place I would be happy to use again."

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