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.

Great service

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!

Replaced blower relay and gave thermostat a call for a/c. Found that as soon as new blower relay picked up it chattered and blew 3 amp fuse. Disconnected g wire at air handler and outside unit came on normally. As soon as I attached g wire to terminal block at air handler relay chattered and blew fuse, found a blew wire going from thermostat to air handler. Switched out blue wire from green wire that was on g terminal, still blowing 3 amp fuse. Checked over low voltage wiring going to blower motor found no knocks. As soon as it was getting 24 volts to t4 motor terminal, it would blow fuse. Removed low voltage speed tap from terminal block and cycled on fan on at thermostat. A/c came on . As soon as I reconnected low voltage wiring to x13 blower motor. Fuse would blow. There is a short in the x 13 blower motor. Motor will need to be ordered and replaced.

Service call that there was water on the floor around the water heater. Upon arrival, found water on floor in basement. Checked Relief Valve pipe and found water in pipe indicating the relief had opened. Checked water pressure with the water heater fully heated and no water running which was at 75 PSI. Tested outside hose bib which was around 75 PSI with the Water Running and 65 PSI when the hose bib was closed off. Homeowner also noted intermittent water pressure problems throughout the house. Also noted the thermostat was turned up to “B” setting which was testing at 142 Degree water temperature at the kitchen sink. Turned Water Heater setting down to “Hot”. Also found Rust along bottom side of water heater opposite to where the Relief Valve is. Was informed by homeowner that there was a previous issue that had been corrected with the old abandoned flue pipe leaking onto the water heater. Pushed the jacket aside to look further into the rust damage and found the insulation wa

Found that circulator pump was constantly running. First found digital thermostat for second floor does not have a common and is a battery thermostat. Customer supplied new batteries still thermostat did not work , he is going to replace the thermostat himself. So just touched the wires together for now and found zone head not working correctly, homeowner had just purchased one so installed zone head and cycled on. Turned on both zones independently of each other and now pump is shutting down correctly.
