"I found this firm on AL and based on the ratings, I hired them to do an annual service check-up on my heat pump. The technician arrived promptly on the date and time we set up. He was thorough, knowledgeable, friendly and professional. I asked him to clean a dusty wall grate and he did it without complaint or additional charge. And $69.95 is more than reasonable for this work. I will definitely use McCrea to service my heat pump from now on."

"They're actually quite good. They're not the cheapest. It's a family-owned business and I believe it was the daughter who assisted me on that evening and while my car was being worked on, she actually drove me to the mall so that my daughter and I could shop while my car was being repaired and that's why I say the service is excellent. This was my first experience with them."

"as convenient for me.  I have a maintenance contract with Valpo and the service was free, as part of the contract.  Also part of the contract is a discount on other  services, like when my heat went out last winter.  They came on short notice and fixed my heat when it was really cold outside.  The receptionist is very organized.  She was the one who called me to remind me that my service was due and then she scheduled it at my convenience.

"Michael arrived exactly on time and took me to sign a lease on my new apartment, stopping twice along the way so I could buy a money order for the security deposit.  He had memorized directions to the new place, which were complicated - we had no problems finding the place and he got me there right on time.  Picking out my apartment and signing the lease took much longer than expected and he waited patiently for over an hour and a half.  He then brought me home.  This was the second time I had used his service and I was just as pleased the second time as the first.  I had to reschedule twice and he was very pleasant about it - in fact he was very pleasant and professional in all our interactions. Even though it took longer than expected and even though I had to reschedule twice, he did not charge me extra.   I would highly recommend him and will use him in the future.

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