"Rob was the service technician who came by for check up on our Trane AC Unit. He was professional and courteous. He took time to explain and label damper settings for future reference. He was the best HVAC technician I have ever encountered thus far. Rob is definitely an asset to McCrea company. If I ever need service again, I want Rob to be the one to service my AC Unit. Thank you!"

"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. 👍"

FAQs for central a/c service or repair projects in Hanover, PA

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.
