Get matched with top air conditioning pros in Frederick, PA

"I was shown pictures of problems that I did not know was going on. I have had a heat pump in my Attic and I showed that mold was in and around my unit. I am thankful to James for showing me this and I was told about equipment that can be installed to make sure that we do not breathe this air that can come into our house. I got the repairs done today. I asked James to send me information about the type of unit that they can install to help with this problem."

"Great guys to work with. Installed 2 AC units and a furnace in one day with only 2 days notice in the middle of July. All at a decent price."

"JP Works responded immediately to our request for an estimate. Dave did the preliminary inspection and estimate. Very knowledgeable and professional. Jim did a second inspection of our house and provided additional information about the work to be done. Jim and Victor did the installation of a new oil-burning furnace and central air-conditioning unit, as well as removing and disposing the old furnace and duct work. It was a professional job from start to finish. We were amazed at the amount of work that needed to be done, but Jim and Victor made it seem effortless. We are so grateful to finally have the central air-conditioning, just in time for the recent heat wave! We hired JP Works based on numerous positive online reviews and we were not disappointed. We highly recommend them!"

"Greg and Chris did a great job. Very professional and thorough. They even cleaned the dryer vent and sanitized the air ducts free of charge. I definitely recommend them ."

"Came out for emergency air conditioning service. Had to shut down air conditioning for a night to thaw out the ice that formed around the unit. We had to put up window units though because it was way too hot in the house to sleep. Originally, we were told we might need to replace our entire unit. After I called back stating our current unit was still under warranty, they came back the next day, and remarkably all we needed was a freon top off. Total cost for the 1/2 cup of Freon and initial visit = $300. I will not be using them again."

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"Matt was prompt and gave his professional advice at no charge. In the end we donâ t need to install a centralized dehumidifier, but because of his honestly and level of experience we have decided to use this company for all of our future HVAC needs"

"Hl bowman were amazing they fixed the issue very quickly! They do quality work and are very honest. Our ac is working without any issues!!"
