"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."

"Exceedingly STELLAR work; BEYOND professional decorum elicited by the company’s OWNER AND staff MEMBERS (specifically the technicians that performed the installation). Overall, we HIGHLY recommend this company to neighbors, family, friends, coworkers & even strangers in our community that may be in need of any HVAC or others services for their homes and/or businesses. Financially, they were on par with our anticipated costs for the work we needed done. FAST, QUALITY WORK that we’d NEVER hesitate calling on again for any future needs that this EXCEPTIONAL, ‘5-star worthy’ company provides! Thank you especially to Ron, Carlos and Brandan… we truly enjoyed meeting you and the pleasure of your company while you worked diligently in our home was all ours. Perhaps this review seems “over the top”or contrived, but we truly wanted to reward this company properly with a review that sufficiently and congruently matched their “talk with the walk” behavior. As you (a co-consumer) know there are so few these days that that elicit good, old- fashioned business ethics. We want you to know this was honestly a job TRULY well done!"

"Bill and his assistant were very nice, friendly, experienced and professional. I was very happy that Bill contacted me within less than half hour of my submitting an inquire through home advisor, and I also like he confirmed his work before leaving and explained the problem of system during the work. This is the kind of customer service that will make me use him for all future plumbing work. Highly recommended."

"Jeremy and his team gave me the best contractor experience I've ever had. He listened to what I wanted, provided a fair quote for a central A/C replacement (air handler and condenser), and never pressured me or tried to upsell. In passing, he mentioned a heat pump option for the shoulder months to reduce oil use, but that was it. After doing my own research, I called him back with questions, and he took the time to walk through the pros and cons honestly. There was no sales pitch, I actually asked for a quote heat pump quote too, because I saw the benefits myself. I ultimately chose the heat pump and appreciate that Jeremy gave me the information needed to make an informed decision. His crew was fantastic, friendly, professional, and thorough. They removed the old system and completed prep work on day one, then finished the install on day two and walked me through everything. Great communication, great pricing, great workmanship. I highly recommend Jeremy and his team!"

"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."

"It's a rare thing when you find any contractor who is both an expert at their craft AND honest! When initially calling on Lloyd for help with my failing central air system, I was skeptical about all the 5 stars reviews. However, I quickly learn that the reviews were spot on. I plan retaining Lloyd's services for all my future HVAC needs."

"Found on HomeAdvisor. Nice woman answered. Booked a service call for one hour. Tech arrived a few minutes early. Dwight was very knowledgeable. Assessed the situation and fixed it. Fair price and I would both use again and recommend to anyone needing service of this type. Iâ  ve grown used to being disappointed in most service companies. This one was a great exception to that. Thank you. Rob"

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