"Of the five bids I received, Michael Bonsby Heating & AC company proposed the best value for the price. From start to finish, through removal of the old furnace to installation & operation of the new furnace, the service technician was knowledgable & experienced in doing the work, and helpful in answering questions and explaining the use and operation of the new furnace. The office staff was also responsive and courteous whenever I called with questions or scheduling of installation. I'm very satisfied with this company and recommend them highly."

"⭐⭐⭐⭐⭐ I had a great experience! He repaired my heat pump quickly and professionally. He was knowledgeable, punctual, and took the time to explain what the issue was and how he fixed it. The repair was done efficiently, and everything has been working perfectly since. It’s hard to find someone who is honest, reliable, and takes pride in their work, but he definitely does. I highly recommend him to anyone needing HVAC repairs or service!"

"JDL called within 30 min of placing my request and set up a visit. They evaluated my AC unit and agreed to repair, despite its age (more than 20 years old!). The cost was a fraction of a new unit. Their lead service tech, Isak, was great - knowledgeable, efficient and responsive to my questions. I was very impressed and will have them return for maintenance and service in the future."

"I cannot say enough of the service, expertise & care of At Your Service. You couldn’t ask for a nicer or a better bunch of guys/team for all your HVAC needs & servicing. I contacted AYS in 2025 for a 2nd opinion of my 20-plus year old system. Jason from AYS arrived the next day & spent several hours inspecting & analyzing my unit. Bad news...it was shot. They could do minor repairs to keep it running as long as possible but I needed a new system. As my finances were tight, I approved the repairs. Those repairs took me through our deep freeze winter & the 100 degree temps of 2026 but she just finally quit. Again, I called AYS & Jason arrived the next day to inspect my unit. He gave me the bad news & offered 3 estimates for a new system. I chose the mid-line Bosh. Their installer, Tommy & his helper, arrived the next morning at 8:45 & worked non-stop until 4:00. I want to personally thank all the guys at AYS & let them know how very much I appreciate them for the kindness, concern & mo"

FAQs for central a/c service or repair projects in Baltimore, MD

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.
