Absolutely the best contractor I've dealt with locally!

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!

Reviewed project with Tom and talked about specifics of what Tom was looking for in regards to equipment options and scope of work. Tom to send over blueprints so load calc can be completed to finalize sizing and change up options to reflect outcome of our conversation.

Reviewed installation for attic gas furnace and ac installation. Trunk system is bubble wrapped and could not see how well sealed the main trunk is. Flex ducts come off of system, most likely there is wall stack feeding the first floor. Covered all of the supply vents for registers and connected the fan to the return. Turned on system and ramped up the pressure to 25 Pascals. Measured duct leakage. Found several areas of leakage around cabinet and return connections. Sealed with tape. Remeasured at 181 cfm25.

Reviewed home to see what the best options are for furnace replacement and or adding ac. Returns on first floor only. Load calc is required and it may be best to insulate the home at the same time.
