Prompt and professional follow up service

I was experiencing a problem with my dual fuel system controlling and engaging the auxiliary heat properly. My system had been newly installed in the summer, so when I brought the heating issue to Dibiase's attention, they promptly dispatched the technician later in the afternoon after calling them to follow up and troubleshoot my issue. My technician, Luis, double checked the wiring components in my system and diagnosed the software and setup issues in the thermostat which corrected the issue. He also promptly took care of some some other concerns I had with the system very satisfactorily and made some helpful suggestions. He also pointed out a minor propane leak he identified while he was working so I could follow up the safety issue with my propane supplier. His service and attention was much appreciated, as was Dibiase's attention to thier service and installation.

A great vendor for a landlord to use

I have used DiBiase before, when my previous HVAC vendor let me down because "it was inconvenient". My tenants texted me this morning, and the team was there by noon, and done in an hour. But best of all, they were courteous and communicated with the tenant. So, my tenant is impressed, and happy with a warm home. And that makes me happy.

Highly Recommend DiBiase for their service. Their technicians are very knowledgeable and professional. They prepared a proposal before the work was completed so we knew the cost upfront. The technicians were on time and friendly and we liked getting a text knowing they were on the way.

a happy repeat customer

This is the first time that Brian, the technician serviced some rental property heaters, as part of the maintenance plan. There are no surprises, and a lot of communication before, during and after the appointment. DiBiase wants to know that the customer is satisfied....and I am!

Found water on floor around pressure relief valve piping of MrsGodwin’s Utica Boiler. In conversing with Mrs Godwin the pressure relief valve started opening a couple of months age. I Dried floor area and emptied buckets that were being used to catch relief water. Cycled boiler on using first floor stat; watched T/P grage on boiler. Relief valve started trickling at 25 psi. Boiler pressure climbed to 30 psi within 5 min of making the call for heat. There is a severely corroded gate valve in the piping of the drum style expansion tank. Replace boiler pressure relief valve, fitting in piping upstream of expansion tank. Replace expansion tank with bladder style tank.

Filled pump basin and tested to ensure it was pumping out properly. Inspected and tested electrical components on indoor and outdoor units. Put system in cooling mode and measured refrigerant charge. Used Charging jacket to elevate outdoor temperature at the Condensing unit. System operating to standards upon completion. Homeowner is looking into having the Ductwork cleaned. Recommended contacting Mold N More for duct cleaning. https://moldnmoredecon.com/ Would also recommend having an Air Purifier installed after the ductwork is cleaned to help with the Air Quality in the ductwork and in the home.

Found communicating carrier system locked out at air handler on a code 44 at control board. Looked up code and found it to be control board not communicating with ecm motor. Recommend to homeowner to replace both indoor control board and ecm blower motor and add a surge protector to motor. Called distributer for price and availability. Was not able to get a hold of distributer, will contact on Monday to get price and availability. Homeowner has hot water baseboard for this area of the house.

Performed precision a/c tune up on 2 trane a/c systems. Both Aprilaire 413 air filters are ok. Blew out condensate drains. Tested condensation pump with water. Checked all electrical conections and components. Checked temperature split, checked refrigerant pressures. Both a/c systems are working fine at time of inspection. Also notice 8 year old Bradford white water heater was constantly re lighting itself during a call for hot water. Possibly failing gas control valve, recommended due to the age of the water heater replacement would be a better option. Gas estimate for replacement.

Installed new Bradford white 50 gallon natural gas powervented water heater. Adapted to exsisting copper piping with new 3/4” copper and propress fittings. Homeowner had an exsisting flood stop set up and wanted it transferred over to new water tank. Transferred over flood stop control. Checked fittings for leaks. Set water heater to hot setting. Found no pressure reducing valve in the house and found pressure at 80 psi. Let homeowner know this is a little high. Let him know if pressure becomes an issue, a pressure reducing valve would need to be installed and drywall would need to be cut. Water heater is working fine at time of install.
