"I called and scheduled an appointment for repair of our central air conditioning unit. These guys are on point! Sucoy showed up on time and knew exactly what the problem was and advised me on what I should do. He was very knowledgeable to say the least and a super nice guy. I would highly recommend this company to anyone looking for an excellent HVAC company! I see now why they are rated so highly on Yelp and they deserve the great ratings."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"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.

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.
