Air Conditioner Installers in Harleysville, PA

"I thought the salesman mike was great. He answered every question i had and was most knowledgeable about the inner workings of oil burners. My installation team was outstanding. It was like bang bang. My oil and hot water was installed in 2 days with hot water heater installed on the first day. These guys were clean and efficient . Two thumbs up!"

"Universal Air went above and beyond. My husband and I wanted a second opinion on our water heater replacement, as our was starting to leak. They not only came out the same day that I called, but answered all of my questions and came in with a quote that was half what a larger chain gave us. They were able to come out 3 days after, to replace our unit. They were on time, respectful of our home, and took the time to make sure we understood what was being done and how our new water heater worked. And even when literally a half hour later I called with more questions; took the time to come back over, double check everything, answer my questions, and tweak the system at no cost. Would recommend and use again."

"Andrew very patient and knowledgeable young man. I enjoyed working with him. Not to mention he was the best job and price out there!"

"He is very well spoken and great at what he does! I have already recommended him!"

"My mother was happy to get this done. They worked efficiently and completed the task. They helped her with another job as well. Overall I would hire them again."

"Easy to work with, great work, great installations, I have not had any issues and did it in a timely manner."

"Very professional, cost effective, and competent. Will hire them again!"
