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!

PECO Air Sealing and Insulation Project * Perform blower door test and calculate target for the home. * Install rafter vents at attic roofline to ensure ventilation is not negatively impacted by adding insulation. * Move insulation and air seal attic plane with single part spray foam and place insulation back into place. * Replace (2) 4" flex bathroom vent lines with insulated flex to prevent condensation. * Install recessed light covers on 3 light fixtures and seal from attic space. * Add more insulation into attic space with blown in insulation to achieve desired value. * Build dam around attic hatch, increase insulation value with foam board, and install weatherstripping on hatch to seal. * Air seal sill plate and space between drywall and block wall in garage area with single part spray foam. * Dense pack garage ceiling with fiberglass insulation. Try and feed insulation into soffit where ducts are located. Holes will be drilled to fill cavities, we will plug h

Performed QA on Trane Gas Furnace/AC system. Reviewed installation with homeowner. He wants his NEST thermostat to control the heating stages, not the control board. It is only 5 Wire ran to the thermostat so their is not enough wires to do W1 and W2 at the thermostat. He claimed that we ran a new wire so he’s not sure why they didn’t run enough wires. Wire looks accessible to replace. It goes through some spray foam when it runs up next to duct work through the floor. He would also like to schedule the Six Month inspection for the spring so we can check the refrigerant charge. We need to replace the Flue Piping also. They left the original flue piping except for one section. The flue is rusting and should have been replaced. Will need 3 - 2’ Sections of 4” Round Pipe and 3 - 4” Elbows. I did not mention anything about the flue pipe to the homeowner. His concern is the thermostat controlling the heat stages.
