 Trustindex verifies that the original source of the review is Google. J1 Heating and Air did an outstanding job installing our on-demand water heater, new furnace, central air, and HRV system. From start to finish, the team was extremely professional, knowledgeable, and respectful of our home. The installation was completed efficiently, with great attention to detail, and the quality of their work really shows. Everything was clearly explained, and the job site was left clean and tidy. We’re very impressed with their workmanship and would highly recommend J1 Heating and Air to anyone looking for reliable, high-quality HVAC services.

 Trustindex verifies that the original source of the review is Google. I have had J-1 out twice, they did a new blower on the furnace and cleaning maintenance on the furnace and outside AC unit.  Also had them run a gas line for a new appliance.  Each time they were great to work with, good communication, Kason is so nice and polite, they did a great job!  Reasonable price, fast and reliable.
