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!

Found system running thermostat was set to 75 degrees and was at 83 degrees inside temperature. Homeowner showed me were he was getting water at and had already dried up water prior to my arrival. Went over System and found system was low on charge. Only the air handler was replaced ( not the heatpump or lineset). Recommend to homeowner to add refrigerant and leak dye to get the system working for now. Then return and try to locate leak dye in about 30 days. Or replace the outdoor heat pump to match the indoor and replace the lineset. Homeowner want to check for the leak dye fist before making a desicion.
