Excellent service

Chris was remarkably thorough and communicative with lots of information about options open to us. Instead of pressure to take the expensive way, he provided ideas on how to simplify and save. The service itself was excellent.

Amazing!

We have used many HVAC companies and found a true gem in DiBiasi! Professional, knowledgeable, courteous and prompt. We have used them for maintenance for nearly 4 years and just recently replaced our 12 year old system with wonderful success. Thank you DiBiasi!

New Heat Pump Installation

Performed Precision Air Conditioning Tune Up on First Floor and Second Floor Systems. Replaced all Air Filters for both Systems. Closed Damper on Humidifier and turned off at the Humidistat Control. Cleaned Drain Lines and the Condensation Pump that is with the First Floor System. The Vinyl Tubing appears to be dirty and getting debris in it. While cleaning the Pump removed Vinyl Tubing and blew through to ensure it was clear. Filled Pump and tested operation to ensure it was primping out. Checked Electrical Components on both Systems. Measured Refrigerant Charge on both Units. Both systems are running, but are doing so inefficiently. Amp Draw on each Compressor is within rating, but is slightly higher than normal. This could be attributed to the age of the Systems. The Compressors are working harder to run than usual. Do to age of the Systems, would recommend begin planning for replacement of the First Floor and Second Floor Systems. Thank you for renewing your Service Membership fo

Checked no cooling complaint, found breaker tripped, found bad dual run capacitor, also a shorted compressor on 14 year old heat pump can’t read outdoor label but the unit next door is a 2 ton heat pump. Recommend replacing system due to age.
