Great service

Chris performed several tests to make sure all potential issues could be addressed. He was able to get the heater up and running so that we could at least have heat until we replace the unit.

Cooling Tune-Up and Minor Issue

As always Luis was prompt, and professional. He did his annual cooling maintenance and also addressed a minor issue with the furnace. During the COVID-19 pandemic, he wore the proper protective gear and I just let him do his work. As always, a happy customer.

Excellent work at a reasonable price.

Kurt, Paul, Dave, Stephanie, Sarah & Joe are just the best. It's been my experience that they are highly customer-focused & regularly go above & beyond to ensure a quality experience for their clients. Can't say enough good things about DiBiase HVAC!

Concerned over gas leak.

Luis was our technician. Because he has done much of the maintenance on our units after install, he is very familiar with our system. Luis is friendly, efficient and takes the time to listen to all of your questions and explain everything in detail. I've dealt with a number of different HVAC professionals as we used to have a home warranty company. Luis and the other DiBiase techs are significantly better than any of the other HVAC company's that serviced our older HVAC system.

Fall Maintenance

Luis was the technician who serviced our Central Air in the spring, and serviced the furnace for the fall as well. Luis was prompt in his appointment window, friendly and answered all of the additional questions I had. Everyone from DiBiase has been very professional. Luis was great with offering little tips on what I can do as general maintenance in order to keep the unit running well into the future.

Emergengy Call

There was concern I smelled gas coming from an area right by my water heater. I called DIBIASE at about 10:30 AM thinking I would have a technician out the following day. The scheduler recognized the urgency of the situation and had a tech out the same day at 5:30 PM. The tech had been to our house before so it was nice to see a friendly face. He was able to diagnose the issue quickly and completed the repair quickly as well. The repair was completed in about an hour. As always, The tech was very friendly, personable and answered all my questions.
