"Talked to a lot of companies. Mike was about as dte & real as you get. Immediately got good vibes. He sent his 2 son's out to check out my AC unit outside. I'd gotten varying opinions & estimates. Tbh, I became weary, but I figured Mike wasn't feeding me anything but what was real. His boys showed on time, extremely polite, well mannered, knowledgeable & professional. They went right to work. Found the problem without trying to sell me a bunch of extra stuff or pad the price for something it didn't need. Without hesitation, I said do it! I have to admit for 2 very young guys, they knew what they were doing. When they were done fixing my system was cranking it out & putting like a kitten. I was afraid out what my bill would be. Couldn't believe how fair & reasonable it was. No extra fees, taxes, add ons etc...EXTREMELY IMPRESSED...I definitely found a HVAC + Co on the Eastern Shore I trust and highly recommend them. Family business & it shows with pride they take it seriously..."

"I had HP Services install a new AC system in my home. David, the salesman, sized the unit right and did not try to oversell something that I did not need. I had three quotes from different companies and HP Services was the only company within my budget. So with the best price, top notch quality workmanship, and a knowledgeable salesman, I will recommend HP Services & Sons, Inc. to anyone."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"After leaving a message on Angie's List on Saturday, Jim Stephens responded within an hour or so. After exchanging information, he volunteered to make a service call the next day Sunday. Because of my 5-day work week, this was a big relief. On Sunday, he called, as agreed, and asked if he could be at my house in a few minutes. As agreed, he arrived promptly. He diagnosed the problems and, at my request, provided details for solution fix. He had the part in his van and explained how the fix would be done and how it would work. He answered questions and explained clearly and thoroughly. Before beginning the work, he gave me an estimate, which I agreed to. After the work, his stated charge was no more than what his estimate had been. In addition to providing a high-quality solution, he provided, at my request, education about a related issue - the exterior drain for the sump pump. He thoroughly explained how the exterior drain could be extended away from the house to mitigate the fact that the water flow was eroding the soil near the foundation. When Jim left, I was a completely happy customer. I knew that 1) it was not necessary to replace the sump pump and 2) I had the knowledge, going forward, to know how to routinely check and maintain the sump pump functionality. Without hesitation, I can honestly say I will be calling JM Stephens for all my plumbing issues in the future."

"They're very responsive. There were some trouble with the system but they got it. They were persistent and got it fixed. There were problems with the system. I'm not sure whose fault it was that there were problems with a brand new system. I think it was very reasonable."

"Sens Plumbing arrived on time and performed the repairs to the water heater as requested. They recommended a service contract to perform future recommended service which we accepted. We also accepted their recommendation to install a pressure relief tank which is currently code. We would hire them again."

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