"I was recommended to McCrea in 2018 for a new furnace and a/c. From the very beginning I was impressed by their promptness, delivery of estimates and ability to accommodate my schedule. They did a great job and the system they recommended for me worked out perfectly for my home. I was so happy that I contacted them again in 2019 to replace my hot water heater. To save time I was able to send pictures of my existing unit and they were able to provide an estimate within the hour. The estimate was competitive and McCrea was at my house the next day 10 mins before start time. I highly recommend them and would call them again."

"It was terrible. I hired Jesus to STAIN my deck. I started powerwashing the deck myself to save some money, but I ran out of gas. You'll see the first two pictures of where I power washed vs where Jesus powerwashed (my job is the smooth looking part). The second two pictures are to show you how small my deck is- and I was charged $800.00!! I didn't have time to search around for other handymen because my deck was, at that point, halfway powerwashed and I was in a rush. Also, I'm a 30 yr old clueless female with handymen stuff, which I'm sure Jesus used to his advantage. But when people came over and told me how much I was ripped off, I asked for him to redo it or give me money back. Jesus was rude and said if I write a bad review he knows what he'll say back. "One year warranty" is bull."

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