"Sean was very prompt in responding to me request for service and did his absolute best to accommodate my schedule at my convenience. He was very flexible overall and helped get my AC repair ASAP after it was broken. This was especially helpful since it was getting warm outside! He was on time for all of our appointments and communicated what needed to be done/fixed clearly, so I wasn’t left with a huge bill that I wasn’t expecting. Expectations are very important and he seems to understand. I would highly recommend Sean and/or his team for any issues you might have for a cost effective and friendly solution. Thank you so much for your help Sean!"

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself! Glad to have signed-up tonight as a member - eligible for discounts tonight and future maintenance services. Highly recommend!"

"Very satisfied with responsiveness, punctuality and professionalism! Danny was able to squeeze us into Blue Star's full schedule at a time that worked for us and called before the visit for clarification about the problem, and after the visit about how things went. John called before arrival to let us know about exact timing, and was very thorough in investigating the problem and then explaining the situation. After consultation, he was able to repair our system. John also discussed what to look out for in case there are problems in the future. We have had our AC unit serviced regularly by other companies, but we will never use those other companies again. Blue Star is superior in every way! Cannot recommend highly enough. Thank you, Danny and John!!"

"Just had an emergency visit to replace capacitor in one of my two HVAC units. Was able to schedule my favorite tech Kevin through the excellent front desk staff. Called in early morning and same day repair work - and Kevin fixed the problem even though the house electricity suddenly cut off halfway through the visit due to the remnants of Hurricane Debby coming through. Our family been with Holtzople since 2008 with the installation and maintenance of two TRANE heat pump units. We have always been extremely happy with Holtzople. Their expertise and knowledge of HVAC operations is superb. But most importantly, from the HVAC techs and Kevin to the front office staff, the people at Holtzople are kind, helpful and genuinely interested in taking care of us. This shows in our semiannual service plan visits as well as the rare emergency needs that pop up like the situation discussed above. And we have been very happy with our TRANE HVAC units. We will have Holtzople as our HVAC company forever. We highly recommend them to all our local friends and neighbors in central Maryland. Simply a great company with great people. 👍"

"The repairman was professional, courteous, efficient, and friendly. We called for emergency help as the heater failed to come on, on a cold Sunday. He arrived within an hour. He quickly identified and repaired the issue. I recommend their service to all."

"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 Frederick, 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.
