Get matched with top central a/c installers in Unionville, PA

"ECC installed a new condenser and coil. Tony, who is one of the owners, did the job himself with two assistants. He was very personable, respectful, and thorough in his explanation of the work. The work was done in a timely and efficient manner, the work zone was left in clean condition and the installation itself appears to be very neat and professional. My strong impression is that Tony and his co-owner, Ed, are two highly experienced and professional craftsmen in this business who take pride in their work and I appreciated having the actual owners, not salesmen and crews, developing the proposal and performing the installation. The entire experience, beginning with Lisa at the office, Ed, who developed the proposal, and finally with Tony and his team, was excellent and I will certainly hope to engage them for future HVAC needs."

"This was the 2nd AC system I’ve had installed. The Mattioni team installation team corrected a few items I now realize were not installed correctly the first time. I do recommend Mattioni."

"Sales rep measured rooms and windows to perform a load cal'n. Proposed a quality Carrier system at a reasonable price. The installation took a little longer than expected due to use of an inexperienced helper, but eventually it appeared to be a quality installation. They met my requests for minor modifications/enhancements to allow easier maintenance. Workers wore masks at all times, used drop cloths along walking paths and shoe covers, so the job was kept clean. Took time to explain system, installation and maintenance points. Were honest about risk of condensate pipe freeze-up and potential remedies, and "orphaned" water heater. Overall, quite satisfied with the equipment and installation. Awaiting finalization of punch list paperwork items."

"Both our inside and outside A/C unit was freezing up with ice.  When the ice would thaw, we would get a lot of water in the basement.  We had a different company come out first who told us nothing was wrong.  We then called DiBiase.  Joe came to our house on time as scheduled, found the problem and fixed it.  He was very helpful and got the job done quickly at a reasonable price.  I would definitely recommend them, we will be using them again in the future.

He put on she covers to protect my wood floors, worked very neatly and gave us some tips about ongoing maintenance. He did a perfect job. This review us for Petro in central NJ. i was not able to change the company location. We hired them through Amazon."

"Everyone was professional, knowledgeable, and helpful. The sales process was not too aggressive, and I didn't feel like they were over selling me something. The installation was done quickly and efficiently. I would recommend them and use them in the future."
