"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.""

"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."

"Well temperatures outside were hitting the high 90's for several consecutive days so we were desperate. Unfortunately, every HVAC provider that we called were booked solid for the next week. I was in a hair salon and after being there about an hour I noticed a man in uniform come in the salon the name on his shirt said All City HVAC. I mentioned to my stylist that it felt great in here already and that I was in need of HVAC service at home. She introduced me to Mr. Smith, he pulled out his phone where he had his schedule and said he could meet my husband at the house in an hour because he was just doing service check ups. I phoned my husband who was Leary at first that someone in that field would be available, however he met Mr Smith at our house within the hour. 2-1/2 hours later I returned home and not only had the problem been identified - we needed a new compressor outside and the unit in the attic had never been replaced but repaired it was 22 years old. Mr Smith retired 6:30am the next morning and worked with his assistant for hours in the attic where temperatures were over 100 degrees. By mid afternoon they were cleaning up and my house was feeling like we were in Alaska! Great experience. I would and have recommended Allcity HVAC services"

"Valpo Services provided a great service from start to finish. Our house was built in 1925 and did not have air duct only window air conditioning units.
After we made the necessary research and requested several quotes, we decided
to use Valpo Services for the installation of a Central Air Unit. Walter came
to our home and provided us with several different options for a Central Air
Unit that would fit our home and needs. For the first time we did not feel pressured
to buy a specific Unit. At the end of the day Walter provided us with a really
competitive quote and showed us a timeline for the installation. Our questions
were always answered on a timely manner. Walter, Hector, Alex and the rest of
the team were always on time, worked hard to make sure the unit was installed on
time and always made sure we were satisfied with the work.  We are very pleased with the quality of work,
service and professionalism the company provided us with. We will highly
recommend Valpo Services to colleagues and friends and we will certainly continue
to use their services.

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