"As a new customer, I was surprised and pleased that the service could be performed on the same day I made the request. Mike was very thorough and professional, and provided a clear explanation of our system and new wi-fi thermostats. Everything was done efficiently - I am looking forward to having Grove maintain our system on our annual maintenance plan."

"GAC has always done a good job maintaining my system. When it was time to get a new system, I was given four options by Eric, ranked standard to best. After each option was explained, I decided to go with the better option. The team of Matt, David and Sam arrived on time and did a fantastic job with the installation. When the job was completed, they cleaned up, explained the new system and answered all my question. I highly recommend GAC."

"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 have had a service contract with McCrea Heating and Cooling since I purchased my condo unit new 7 1/2 years ago which included 2 maintenance visits a year. My current contract expired yesterday so I called to renew my service contract and upgrade from "Bronze" to "Silver." The representative took my charge card information over the phone. I asked if the contract was in effect as of today. They said "yes." Then I tried to schedule a service call (my unit was serviced a little over a month ago and now the condo wasn't cooling.) I was told then that the Silver Contract would NOT be in effect after all. The difference in price between Bronze and Silver is the cost of a diagnostic visit so they were getting the money one way or another. My long time history with the company did not persuade them to honor the contract I had just paid for. They wanted to charge me $98 to have my problem diagnosed under the Bronze contract that I pointed out was already expired. I was told the representative "misspoke" and should have told me they would have to send out someone to determine whether the furnace they have been maintaining for the past 7 years (with the most recent service call just a month ago) would "qualify" for the Silver plan. So, I cancelled the order for the Silver Plan. I called another company who came out for $30 and determined the problem was a clogged condensation drain. This drain was supposed to have been "blown out" when the regular maintenance was done by McCrea just a month ago, but obviously was not. The water was backed up in the drain pipe and filled the pan under the furnace/AC unit which turned off the AC. Now that everything is working again, I am seeking a different maintenance service plan provider. McCrea has competitive service contract prices, but if they have no customer loyalty, and the maintenance work is not done properly, maybe it's a question of "you get what you pay for.""

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