What is HVAC?
HVAC systems are comprised of the heating, air conditioning, and ventilation systems in a residential or commercial building. These mechanical systems provide thermal comfort and air quality in indoor spaces. Types of HVAC systems include air conditioners, heat pumps, furnaces, boilers, rooftop units, chillers, and packaged systems. A building’s HVAC system encompasses components such as ductwork and air handlers which are essential to system performance.

Here’s what just some of our clients have said
I’m delighted to add another 5-star review for Chris from CJ’s Mechanical. His customer service skills are great — he actually LISTENS to find out what the problem is. In this case, it was a problem created by an earlier repair person, and Chris resolved it. If I could give 6 stars, I would!(YELP.com)

Love this guy! I got 3 quotes for adding AC, the last nearly double what he charged. All telling me something different to add on charges, all trying to get me to buy a big unit for my little house. Chris did a great job, and I totally trust what he says. So glad I found him! (YELP.com)

Cliff at CJ Mechanical went above and beyond to fix the ice maker in my refrigerator. He came back twice and never charged me. He was truly diligent at diagnosing the problem and wouldn’t stop until he had it running perfectly. I highly recommend his services. He is honest and hard working. Thank you Cliff.(YELP.COM)

They do dependable work, and they’re a company that will get the job done. I would say just that I didn’t have to worry at all about having to call them back out here because something went wrong. They get everything done correctly the first time around as opposed to other companies I’ve used previously, thank goodness. (DiamondCertified.com)
