"Called McCrea Friday morning to schedule for a service technician to come out that afternoon. Got a call around noontime from service technician Dwayne Myers to let me know he was on the way and would be there shortly. When Dwayne arrived he introduced himself and we then discussed the problem, after which he went into diagnostic mode explaining along the way everything that he was doing in checking for the problem. Once diagnosed he explained what was needed for repair and again informed me what he was doing in facilitating the repair. After the repairs were completed he did a thorough inspection of my system to ensure there were no other issues and it was blowing cold and working like new."

"It was an all-around good service & project. I had a large out-building that used to have electric to it. I wanted to add electric to the building in hopes that if I had to sell, then electric to the building would increase the sale-ability of the property. It was an extensive project. They had to dig a trench from the house to the bldg, add a panel box, run wiring through the 36'x36' 2-story salt-box style bldg, provided light fixtures, outlets, etc... a few days after the project was completed, a large rainstorm washed out some of the trenching. They came out within a day or 2 after the storm & filled back in the collapsed trenching."

"They put in a new system. They had to take everything existing out. They showed up when they were supposed to and finished in a week. They were clean and efficient. It was not an easy task. They cleaned up after themselves. Very professional. The owner explained everything to us."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

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