Always great!

DiBiase is the company to trust. You get email and text notifications for everything, so you can see who will be arriving and when. They are conscientious about their clients and their employees, as well as prompt and neat. Technician wore a mask, booties and gloves and I felt completely safe while they did their job. Chris had a great personality too!

Great Timely service and great people

After 23 years of maintenance, they replaced my HVAC this month. And I believe they always did their best to maintain my previous system. They responded quickly when my tenant said the A/C wasn't working right. Great consistent service in 2020 and always.

professional, prompt, respectful, knowledgeable

Kurt was very helpful - as always. Quick response to an emergency was much appreciated. However, I only wish that a member of the DiBiase home service team had strongly recommended to us (prior) to deploy the new Ez trap with the safety valve shut-off float; if we had that unit inserted (prior) we would not have incurred the very significant flooring repair/replacement cost that we now face due to water damage!

Great Service

Many thanks to DiBiase Heating and Cooling for sending Luis to service our A/C unit after working hours. Luis was very informative right from our phone conversation. Once on the scene he diagnosed the problem and stated what the cost would be. He completed the task and tested the unit in timely manner and we were cool once again.Highly recommend Joe DiBiase and his team.

Performed precision heat pump tune up on whirlpool heat pump and Mitsubishi heat pump. Cleaned washable filter. Checked all electrical conections and components. Checked refrigerant pressures on main heat pump system. Blew out condensate drain. Checked temperature rise at both units. Found old Aprilaire humidifier not working, gave October promotion pricing for installation of a new Aprilaire 600m. Both heat pump systems are working fine at time of inspection.

Performed Precision Heating Tune Up on Lennox Heat Pump system. Replaced 20x20x1 Air Filter. Inspected electrical components on indoor and outdoor units. Put system into operation to test heating and outdoor unit was going out in a Short Cycling Error Code. Cycled system and unit would revert to the short cycling error code immediately upon start up. Tested compressor and tested Pressure switches on system. Determined that the Defrost Control Board on the outdoor unit is not working properly. While cycling system, unit began operating. Measured refrigerant charge and tested system. The Defrost Board will need to be replaced or the system may not operate properly. The system is about 15 Years old. Due to age and current issue, replacement of entire system over repair would be recommended.

Performed Precision Heating Tune Up on Trane Heat Pump system. Checked 413 Filter. Filter was clean and did not need to be changed. Inspected and tested electrical components on Air Handler and Outdoor Unit. Found blower capacitor testing below rating. Found Dual Capacitor on outdoor unit testing within rating but towards the lower end of the rating. Replaced 15 Mfd Blower Motor Capacitor. While inspected system, found Growth forming inside of Air Handler. Showed Homeowner and recommended installation of a REME Air Purifier for system. Put system in Heating Mode and measured refrigerant charge. Tested Auxiliary Heat Kit and measured Amp Draw on elements. With warmer outdoor and indoor temperature switched system over to cooling mode to verify refrigerant charge. Also noted while onsite that the Hot Water Heater is about 10 Years old. Average life of water heaters is 10-12 Years. Would recommend begin planning for replacement before any issues occur.

Performed indoor coil cleaning on York air handler. Brushed out fins with coil brush and removed the majority of the dirt. Then used coil cleaner spray and ran unit in a/c mode to wash off remaining debris. Coil is clean and will now have better air flow thru the coil.

Performed Precision Heating Tune Up on Lennox Heat Pump system. Checked High Efficiency Air Filter. Filter was clean and in good condition. Performed Humidifier Servicing and cleaning. Cleaned Humidifier drain line and Condensation Pump. Filled and tested pump. Tested humidifier and set control to 35% Humidity. While performing tune up, found outdoor unit was running when the system was not calling for Heating/Cooling. After testing components, found the Contactor at the outdoor unit was seized in the closed position. Also found Oil on and around Dual Capacitor. Installed a new Single Pole 40Amp Contactor and a new 45/10 Mfd Capacitor for the Outdoor Unit. Completed all wiring connections and put system back in operation. Measured refrigerant charge in Heating mode and tested Auxiliary Heat Kit on Unit. System is operating but is 17 years old. Due to age and overall lower efficiency of the system, would recommend replacement of the Heat Pump unit before any refrigerant or component f

Performed precision heat pump tune up on Payne heat pump with York air handler. Replaced air filter with 18x24x1 air filter that customer provided. Homeowner is going to look into a 17 1/2x24x1 to work better inside cabinet. Found indoor coil very caked up with dirt due to air filter not fitting correctly. Checked temperature rise of system at air handler. Blew out condensate drain. Checked operation of emergency heat. Checked refrigerant pressures and temperatures at indoor and outdoor units. Head pressure is 288 on high side for r-22 system. This is most likely caused by debris on indoor coil. Recommend to start thinking about replacement of system to a newer more efficient system. System is working at time of inspection.
