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 information with Rohn. Install was created by another company and the first floor is 4-5 deg cooler than 2nd floor in winter. System is single zoned inverter communicating Rheem system. Recommended zoning if possible and adding a return to the first floor.
