"The service from Bamford Plumbing & Heating Inc. went great.  He kept his scheduled appointments and had no need to come back because he did everything 100% the first time through.  He is a general plumber, but his knowledge of boilers was exceptional, I learned a lot."

"One of my AC compressors was not starting correctly every time. If it did start, it would run fine, but on hot days, when it would cycle frequently, (i.e. cool to target temp, stop, temp would heat up, thermostat would send signal to restart, and eventually the compressor would not restart). I don't remember the exact explanation, but I think there's a small fan linked to the capacitor. The fan provides some cooling to the capacitor which is stressed at startup time. Eventually the capacitor burned out because it wasn't getting its appropriate fan/cooling. First, this is a pretty specific problem. I'm fairly technical myself, and my father can fix anything. We had isolated the issue to the capacitor, but could figure out why it had failed. This is a large home and the large capacitor, so it really was a job for a professional -- capacitors offer plenty of opportunities to electrocute yourself pretty severely if your a "do-it-yourselfer." The No-Frost tech diagnosed the problem within a few minutes and explained it in detail. I called my old man to see what he thought, and confirmed that would definitely explain the problem. Second, the appropriate replacement part was an all-in-one capacitor/fan combo part specifically made by the vendor. Because my unit was a larger-than-typical unit AND these guys rushed out pretty much same day (or next morning -- I think it was a Friday going into a 95 degree weekend). The tech didn't have that exact part on his truck. He gave me two options, he had the same size capacitor and fan unit separately, so he could merge those together and get the unit functioning right then and there, or he could order the part and come back some time the following week -- he called the warehouse and they didn't have it in stock (my compressor is large and 10-years old). Given the weather, and everything else, I had him build the setup I needed, took him about 20 minutes to link the fan and capacitor together and the AC unit was humming along again shortly thereafter. I loved that he took the time to explain the problem in detail. He could tell i was "tinkerer," yet he was very politely patient with my ignorance (I had no idea the capacitor required its own cooling). I loved that he gave me the choice on waiting for the vendor's "officially sanctioned" part or just getting the unit working, and that he took the time to explain why this wasn't a risky workaround. I gave him a nice tip and emailed my neighborhood HOA email group the contact details as a reliable, trustworthy and well-priced service provider who will always go the extra mile for the customer. These guys fixed my furnace a year earlier when I nearly burned my house down by not paying attention to my intake... Would and have definitely recommend these folks for any HVAC needs."

"Our heat came back on and therefore we didn't need the service at this time. However, they called us right away and were willing to come out on a Saturday to at least look at the problem. Professional Service."

"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!"

"Mr. Bost did an excellent job for me for a reasonable price. I know he obtained the best deal for me on the furnace and the air conditioning unit. He answered all my questions. He was on the job when he said he would be; he was professional and courteous. The installation went smoothly, and I have had no problem with the furnace or air conditioner since they were installed in 2008."

"We've had two HVACs and a water heater installed and I would not use them again. They offer an extended warranty that beats their competitors, but their service plans are misleading and after installing one of our A/C units and supposedly doing "maintenance" on it a year later, we learned when we went to replace a filter ourselves that they couldn't have replaced the filter at the last service because the filter cannot be replaced due to the way they installed the unit. We were told on two separate occasions that we had a service plan with them, but when they were scheduled to do our maintenance, they called to say that we didn't have a service plan, it was canceled due to non-payment (it was never communicated that our plan had lapsed during three subsequent calls). Trust the negative reviews and go with another company"

"I had a 13 SEER A/C and gas furnace replaced with a new 16 SEER system. Farnen and Dermer offered the best value out of four estimates I received. Their customer service and sales personnel were professional and knowledgeable and able to quickly respond to requests and provide answers to questions. They were able to begin the work very quickly and did a thorough job. The 60-month no-interest financing was very important in my decision."

FAQs for central a/c service or repair projects in Long-green, 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.
