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!

Emailed over bids to add mini splits or ducted system in attic
Performed consultation for new ac system and ductwork. Reviewed home. Need to calculate building load before sending proposals.
Performed QA on Trane Gas Furnace/AC system. Tested system in heating and cooling. Performed static pressure tests and temperature splits. Performed combustion testing and measured propane gas pressure. Reviewed airflow settings and programming on system. Removed yard sign from property. Completed checklist form in system. Reviewed installation with homeowner. No additional follow up is needed.
Completed AC tune up for 3.5 ton Amana AC system Replaced Aprilaire 313 filter Measured temperature split and static pressure Inspected EZ trap and drain. Inspected condition of indoor and outdoor coil Inspected wiring controls, electric motors and components Monitored R410A refrigerant pressures and diagnostics REME cell was expired before 2 year bulb lifetime. Determined ultimately that the ballast itself has failed. Removed REME including low voltage conductor and transformer and temporarily patched ductwork. We will return with new REME asap. Next week is better for Barbara’s availability System is operating well at this time. Homeowner paid for filter replacement today,
Completed AC tune up for 2 ton Amana AC system Inspected condition of both the indoor and outdoor coil; clean frame of coil and drain pain of mold. Left estimate for UV bulb system (2 year bulb) Measured temperature split (67-46=21°Good) and static pressure Ensured drains were clear and properly pitched. Left estimate for EZ trap. Inspected wiring, controls, electric motors and components including fan speed. Discussed and left email estimates for surge protectors. Verified integrity of compressor motors using megaohmeter. Monitored R410A refrigerant pressures and diagnostics: Good
Repiped intake and exhaust according to the fact that the homeowners plan on building a deck to the right. I left fittings unglued in case we need to pipe in a different way. There are (2) shower heads that have slightly low pressure since the boiler install was done. One of the shower heads is new including the plumbing (was replaced 3 weeks before we did boiler install). Remaining fixtures in house water pressures in good. She said she will investigate the strainers and shower heads herself. System operating well at this time.
Completed tune up for BOSCh Inverter 5 To 20SEER: Homeowner replaces 20x25x5 filter annually. I recommend replacing every 6 months. He uses MERV 16 filters for allergen control. He said he will replace more often now, Measured temperature split and static pressure. Inspected condition of indoor and outdoor coil Checked ez trap, drain and components Inspected wiring, controls, electric motors and components. Left estimates for surge protection for indoor blower motor. Also left estimate for APCOX whole home air purification system. Monitored R410A refrigerant pressures and diagnostics. 117/232; Subcooling 8° System is operating well at this time.
Completed AC tune up for Bosch Inverter 3 Ton 20SEER 20x20x1 and 12x12x1 filters in good condition. Measured temperature split and static pressure Inspected condition of indoor and outdoor coils Inspected wiring, controls, electric motors and components. Recommend surge protectors for indoor equipment circuits. Intermatic and X13 Checked drain and EZ trap drain terminate behind outdoor equipment (runs with lineset) Monitored refrigerant pressures and diagnostics: 116/145 8°Subcooling. System is operating well at this time. Ultimately determined I could not use an Intermatic surge protector based on wire sizing at line side of breaker. Offered another style of Ecm surge protector that will serve the same purpose. Homeowner agreed to install (2) ECM style surge protectors. 1 for blower motor and 1 for the main circuit at breaker.
Found manual resettable spill switch on draft regulator OPEN. There is water around boiler. Also water on domestic coil. The cause of the open spill switch was a completely blocked chimney. I disassembled flue piping and cleared chimney of debris allowing for clear passageway for flues. Also inspected heat exchanger and noticed while attempting to brush that the boiler leak has caused debris to clog up certain parts of heat exchanger. See photo. Combustion and draft tests pass. Low limit on aquastat 160, high limit 180. Discussed and encouraged upgrading system. Consultation should also involve discussion about how domestic hot water should be addressed moving forward (when system is replaced) options include indirect tank or a separate hybrid hot water heater. Homeowner mentioned that they use a lot of hot water. 4 kids 2 adults. Currently using a domestic coil. Boiler operating ok for now. Homeowner is in tough with a contractor regarding installing a chimney liner. Homeow
Performed QA on Laars Combi Boiler. Glued the front panel onto the door of the unit. Reviewed all settings on boiler and at the new thermostats. Ran system in heating and ran the domestic water. Checked gas piping with an electronic leak detector. Completed checklist form in system. Homeowner mentioned the exhaust vent blows right into the mud room doorway. They use this door all the time to let the dog out. She asked if we could redirect the exhaust pipe to blow away from the door. Will need to come back with some 3” PVC fittings to cut the exhaust and redirect. She said she works from home on Mondays and Fridays.

Inspected wiring, controls, electric motors and components including fan speed. Discussed and left email estimates for surge protectors. Verified integrity of compressor motors using megaohmeter.
