Ok service, ok associate




Review of DiBiase Heating and Cooling Company

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

Review of DiBiase Heating and Cooling Company

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.

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
