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!

Luis 1-12-26 return visit to troubleshoot unit. Found unit with error code e7. I called tech support for troubleshooting, based on the information, from inverter board, discharge sensor should be replaced not reading correctly. We need to replace sensor warranty, customer also has labor warranty, we will need to recover refrigerant and measure how much we take out, and add factory charge once job is completed. No charge 1/15/26 Barry Recovered 5# 13oz R410A; Factory charge is 7# 9oz (121oz) Pressure tested system and it help 360 psi for 40 minutes. Soap bubble leak check all joints. No leaks found. Also no leak detection dye anywhere. Replaced compressor discharge temperature sensor. Triple evacuated system to standards. Less than 500 microns. Charged system factory charge. 121 oz R410A. Started system. Gets stuck at 31 Hz because transducer has failed. Control thinks it’s 455 psi liquid pressure when it is 308 psi measured and therefore prevents compressor from modulating up. Con
Luis 1-15-26 return visit to check hot water issue. After troubleshooting and talking to Joe while onsite. Found that when tub is open at fullest GPM decreases. I time the tub water delivery it takes 1 minute to fill 5 gallon bucket, when hot water valve is full 100%. Water Temp decreases to around 107 F. I told Maria to set valve half way to give time for boiler to catch up with the water demand. At half way water was consistent at 118F. Hot tub takes about 45/50 gallons depending on customer demand. Maria will try This procedure tonight. I called Joe at the end of the call.
Reviewed job and found humidity low in the home. Explained thermostat control and how it can force humidify. Recommend Honeywell S1200 with EIM. Found humidifier valve turned off at water heater. Turned valve back on and tested humidifier operation. Bob would also like to have a price for an inline water filter for humidifier to reduce scale buildup. Discussed options on whole house treatment but Bob was not interested at this time. Add inline water filter to existing quote and resend quote.
Barry was on site when I arrived and installing the S1200 thermostat with EIM. Reviewed kitchen with John and performed thermal imaging on walls and ceiling. There were some cold spots around perimter which is normal and around the drop soffit in kitchen area. The attic is already fully insulated and there is no way to get back into that area above without disturbing the insulation. The walls were rather cold in the kitchen as well indicating minimum insulation. Checked airflows in kitchen space with anemoneter and cacluated airflow at around 100 cfm per run and there are 3 runs in the kitchen. Ductwork is in the attic space and buried in new insulation. Recommended to measure the temperature in the kitchen and keep fan on the system in circulate mode to circulate air and improve air balancing.
