I called in the morning to describe an AC problem and they set up an appointment ..... they arrived ahead of time and were very professional. Problem solved, plus they gave me a quote for a new system, which I requested, during the same visit.

Most professional service provided; right-on-time; courtesy and completeness. Can't say enough positive things about Joe DiBiase and his HVAC team of professionals. Very customer oriented - shame there are not more businesses functioning like they do! Tony


HVAC and Hot Water Heater Replacement




I have been a long time customer and I trust Joe and his team 100%. They are very professional, kind, and technically skilled. I highly recommend them!


The best!!




I know I am in good hands with DiBiase. Nathan is one of the best and takes deep pride in his work. I highly recommend DiBiase for your HVAC needs.


Ok service, ok associate




everyone I've talked with or worked with previously was great. This particular associate needs a little refresher in customer service. When asked exactly what service(s) he'd be performing as part of the check up, he looked shocked as if he'd never been asked that before then struggled to find the words. When at the end he indicated a part was needed and I asked what the part was and what the issue was, he actually said "how do I explain this". I'm well educated son, I'm pretty sure if you use English and explain it at a laymen's terms, I'll be able to understand.


Great Service, Great Team




I lost my air on what felt like the hottest day of the year. Within 1 hour, I made the call, Bryan arrived, diagnosed the problem and resolved it. Great service and Bryan was so nice to work with.


regular service call





Great service by Bryan, but the news (cost) was not a good experience, perse.





Have never been disappointed with this company. Call and your problem can be solved within a day.

Great Service




Its always a pleasure dealing with DiBiase, they have come through in heat outage and are right on top of my annual service, pleasant and Knowledgeable service techs.


Simply the best!




Absolutely love DiBiase and cannot recommend them enough. I've been with them a few years now and bought a new system through them. I trust them so much I'd leave them in my house if I couldn't stay. Shacole in the office is awesome and gets everything set up and ready around my schedule. Bryan was the tech this time and he's great.


Had a new Heat Pump installed




Technicians were great throughout the entire process. They were at my home for about 8 hours and were very respectful of my home the entire time. They worked efficiently and neatly.After they completed the job they tested all the equipment and made sure I was happy with what they had done. They answered all the questions I had and made sure I understood everything they did.


responsive, knowledgeable, understood the problem to be fixed





Everything went very well and on time!




Efficient and knowledgable serviceman... And neat!

Service call that the Gas Furnace was not operating. Arrived onsite and spoke with Homeowner about issue. The system was blowing Cold Air but was not providing Hot Air. Proceeded to the Furnace to troubleshoot. Blower Motor was running and System was in a 13 Flash Code Lockout indicating that a Limit Switch was open. Tested Safety Switches and found the Primary Limit on the Furnace was open. This Limit automatically resets itself and had failed. Bypassed Limit Switch and put system in operation to determine if their was an underlying issue to the failure of the Main Limit. Performed a Combustion Test on Furnace. Inspected and tested Integrity of Heat Exchanger using the Smoke Test. The Furnace is running at higher than normal Supply Air Temperature. Furnace is rated for a 45-75 Degree Temperature Differential and is running around a 85 Degree Differential with a Supply Temperature around 145 Degrees. The Primary Limit is set to reset at 160 Degrees. Inspected the Indoor Coil which had

Service call that the Electric Heat Kit was not working. Upon arrival, Indoor Temperature was at 61 Degrees. Turned Thermostat up to 70 Degrees to test. The Heat Pump was operating in Heat Mode but the Electric Heat was not turning on. The system was only producing about 15-20 Degrees of Heat. Tested Electric Heat Kit and found that it was not receiving Voltage to turn on. Checked wiring at the Air Handler and at the Thermostat. Went through Programming setup on the Thermostat. Put system in Test Mode and the Electric Heat began running. Tested all Heating elements to ensure they were working properly. Turned System back into Heat Mode. The Heat Pump began operating with the Electric Heat. Due to the Nest Thermostat Programming being limited, recommend installing a new Thermostat where the Settings and Thresholds can be set more accurately. Also recommend performing a Tune Up on system to thoroughly test Operation. Recommend the Annual Service Membership Program which provides discount
