"I am a attorney in Nutley, New Jersey. We had no air conditioning on the second floor of our commercial building yesterday. After our regular HVAC maintenance company claimed to be too busy, we researched an alternate and found excellent reviews for Challenger. Access to our roof AC system is a bit tricky. It was no problem for Jorge of Challenger. He easily navigated the approach and the scuttle. The AC was in tiptop share in less than an hour, portal to portal. The price charged was fair and the work was clean and professional. Challenger has a "can do" attitude and approach to HVAC. Thank you Jorge for an excellent job. Based on our experience, I am very pleased to refer this company to others."

"We recently had the pleasure of hiring Dawson Mechanical to have a new Navien tankless water heater installed. This was a little more than a straightforward job since the water heater was being relocated from a utility closet to the garage which was about 20 feet away. From the time I made the first call to Dawson, I had a good feeling about this company. Dave came over within a few days on a Saturday to look the job over and give me an estimate. He is very knowledgeable and took the time to answer any questions we had. When the day came for the installation, a crew of 3 workmen arrived around 9:00 AM and did not stop until the job was finished around 5:00 PM. They did an excellent job, were very good about keeping everything clean and neat, and the workmanship was top notch. In short, we were very happy with everything and would not hesitate to use Dawson for our future plumbing/HVAC needs."
