The best in the business!Posted on Google Dillon WrightJanuary 15, 2026Trustindex 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.Posted on Google Joy StennesMay 28, 2025Trustindex 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.

You are so welcome. Thank you for trusting us. Have a great Thanksgiving and Merry Christmas.Posted on Google Jake SykesJuly 19, 2024Trustindex verifies that the original source of the review is Google. When our newborn was born with an immunodeficiency, we needed a high-tech air purifier to protect him from any illness while we isolated at home. J1 Heating and Air went above and beyond to make sure we had it installed immediately. They even included a box of charcoal filters to ensure the best results. The technicians were incredibly considerate, wearing masks throughout the installation and being mindful to avoid my son’s room. Their genuine care and attention to our family’s health meant the world to us.

One of your technicians stopped to assist an injured bicyclist on Willow Creek this morning. Amazing compassion and called 911. Blessings 🙌
