If you're in the West Chester, Chester County PA area and need HVAC work done - I can't recommend DiBiase highly enough! They were, and are, expertly skilled at what they do, extraordinary communicators before/during/after the install, and a pleasure to work with. The team were all complete professionals. I have high expectations but they exceeded all of them!

Our Spring service was today with Brian and it was another great experience with DiBiase Heating and Cooling. I really appreciate Brian showing up just as scheduled, explaining the service, and being respectful of our home. We are now set for the summer!

Inspected boiler and found boiler has not been serviced in some time. Removed inspection plates and cleaned between sections. Removed and cleaned burners. There was heavy corrosion and rust. Replaced fusible link with 149 degc link which was much lower than the original limit. Put boiler back together and fired. Gathered information for replacement. Performed combustion analysis and draft test and monitored operation.
Reviewed job details and created and sent estimate.
Reviewed job and gathered information to replace classroom systems. Kim would like to balance and relocate reruen duct.
Boiler was overfilled. Drain approx 12-15 gallons to get water level to design. Checked over wiring, One big issue has been thermostat location it is in a corner about 10’ up on first floor where there is a breeze from entrance way. The temperature there is 7° cooler than the temperature in any of the apartments themselves. We installed Honeywell S1200 Elite pro thermostat with equipment interface module and a room sensor. Placed the room sensor on a wall in a second floor apartment and configured new thermostat to use this sensor as the temperature input. Set thermostat target 70° Monitored boiler operations. Set auto water feeder delay period to 10 min. Tightened packing nuts on 3 problem radiator valves. They were very lose. There are a couple air vents that need to be replaced. We will provide estimate. System will run alot less often now by virtue of having temperature being read from an actual apartment.
Reviewed house and equipment. Turned system on and tested operation. Found fan speed for heating at medium high. Ran unit for 10-15 minutes. Measured supply and return air temperature. 115 supply temperature and 69 return.
