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!

Reviewed home and meaured ductwork to configure a plan to relocate return air ducts to first and second floor of home. Plan is to go through living room closet. Also measured space to add a ductless to third floor and repurpose the ducts for the basement zone.
Reviewed home and ductwork. Home performace work was completed by Greenstone and audit was performed on the home by Peco. There is a negative pressure at basement indicating return leakage but ducts are sealed. Need to further investigate. Recommmend zoning or ductless for second floor comfort.
Reviewed home and equipment for relocation of outdoor unit. Measured equipment and scheduled replacement for Thursday with relocation.
Reviewed filter access, filter is being taped on and metal is bent and making it difficult to get filter in and out. Recommend Aprilaire high efficiency media filter 16x25 2410.

Also recommended 1-2 hours of duct sealing in attic space to reduce air leakage and improve indoor air quality.

Recently he discovered mold in basement area. Home has two systems: one for main area of home 1st and 2nd floor with thermostat on 1st floor dining room. Second system does the single room addition in the back of home. Checked settings and wiring for main system. It is a 4ton air handler with 5 ton outdoor.

We need to replace with a 2 stage thermostat T6Pro Wi-Fi for customer satisfaction. Now with the system calling for Y1 it will deliver about 1100~cfm to run longer and help w
