"By far the most professional and customer friendly company I found after an exhaustive search to replace a single zone high wall ductless system. They responded without delay and were able to perform the work the next day. The Service representative who did the survey for a quote (Nick) was very knowledgeable, understood what I was looking for and provided a quote accordingly. I felt he was looking after my best interests instead of selling me something I did not need or want. The installation team (Dara and Charlie) were on time, customer friendly and did excellent work. I am now a big fan of this company due to their excellent customer interaction and quality work. Job well done."

"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.""

"Darryl McDowell, the technician from ARS of Laurel, did an outstanding job while performing my AC tune-up/inspection. He was extremely knowledgeable and very professional; explained all findings in a thorough and easy to understand manner. As a result of his honest assessments and diligence in addressing all issues in a very comprehensive manner, I feel confident moving forward with needed repairs and/or system replacement. Without a doubt, he provided the best service ever!"

"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."

"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.

"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.

"We had a problem with a drain from a window well that would result in continuous flooding in our basement. We were finally able to fix the problem with the drain and hopefully prevent further flooding. So we contacted two businesses about mold remediation and removal of the damaged drywall and paneling. The first company, provided a good estimate but they were not as professional or reliable as we wanted. After searching online we were able to located American Home Services and then used Angie's List and saw they had great reviews. I immediately called them about receiving a free estimate and they offered to be out at my house the next day to give us an estimate. The President of the company was the person who came out to give us our estimate. He was able to explain everything that would need to be done a reasonable time frame (2 days). I received the completed estimate within 24 hours and scheduled the appointment shortly there after. American Home Services responded on time and placed plastic down in the hallway that leads to our basement to prevent any damage to our floors. My wife and I then waited as they worked for the day and after they completed the days work, they then showed us the basement and what they completed. Overnight they left a dehumidifier and other equipment to complete the work. The next day they came back and hand cleaned any spots that weren't completely cleaned within the first day's work. After they were done, I was then shown the basement and the work that was done. I then received a receipt for the services and a print out of all the work/chemicals that were used in the basement during the repair. American Home Services then provided us with a warranty to come back and fix any problems within the first year. Overall American Home Services is a great business that is willing to work with their clients and make sure that their needs and concerns are met.

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