"HVAC Doctor put a new furnace in my town-home a week ago. They were professional, clean and got the job done on time. I would recommend them to anyone."

"I had my 27-year-old furnace and a/c replaced by them. The entire process was effortless. Joe and John were great to deal with. The 2 techs that came out were very friendly and efficient. They had the whole project done in less than a day. The clean-up and explanation of the new system met and exceeded my expectations. The new furnace works great and is much quieter than the old one. We only had a chance to run the air for one day, and it also worked very well. I would highly recommend Air Comfort Heating and Air Conditioning for furnace and a/c replacement"

"My God! Dan came out this morning, I explained what was done, he went to work on it right away! My furnace stopped working December 25th, 2024, no heat till today! Keep in mind, the last technician I hired in January 2025, charged me 240 dollars for 20 minutes analysis just to tell me I need new furnace and AC central, my AC works beautifully. Then I used 4 space heaters to keep my house warm! Man my electric bill was over 400 dollars the first month and climbing higher each coming months till Spring arrived! I hired B & D Plumbing and Heater Co. to come out and finish the job. It was a gentleman name Dan, he did an extremely awesome job, telling me the details, explaining everything I needed to knowledge. And now the furnace works about as good as it gets beautifully. The impressive part, he took his sweet time. And the most impressive part was when he presented my total bill! I was about to have a major heart attack when I saw the bill! It wasn’t through the roof bill! Cheap cheap"

"I recently had Prolific Mechanical install a new air conditioning system, and I couldn't be happier with the results. The young man who completed the installation was professional, courteous, and extremely knowledgeable. He took pride in his work, kept everything clean, and made sure the installation was done correctly from start to finish. The new system runs flawlessly and keeps the house comfortable even on the hottest days. I highly recommend Prolific Mechanical to anyone looking for quality workmanship and dependable HVAC service."
