I called Exxel about what I thought was an airflow issue, and upon investigation, they determined there was nothing to fix and gave suggestions on how to deal with it. They didn't try to sell me services I didn't need and I was really impressed with their honesty. When I asked about the overall health of my heat pumps because of their age, again, they determined they were fine and replacement wasn't eminent. Their integrity was impressive and I highly recommend their company. I will definitely use them for all future needs!
Awesome work on our boiler and indirect water heater install. Excellent, quick, responsive service. Highly recommend! :Mike
Super impressed with Exxel Mechanical Services. We woke up to find our HVAC acting up. I called Exxel at about 9am to see if they could help. Bob and another gentleman were able to arrive around 1pm and had everything back in working order only 30 minutes later. They were extremely quick, helpful and professional. Also very reasonable pricing. I can't thank them enough!
My air conditioner went out on a very hot and humid day. Exxel was able to squeeze me in same day. The technicians were very polite and courteous and answered all of my questions. They quickly found and fixed the problem. I thought the price was very reasonable.
I called Bob @Exxel in the late AM, he was out with his apprentice Eric right after. We discussed the problem and they started checking things. They were very professional and explained everything along the way. Thanks for everything, Exxel! Now I've got a happy wife & 5 month old.
