Ok service, ok associate




Review of DiBiase Heating and Cooling Company

everyone I've talked with or worked with previously was great. This particular associate needs a little refresher in customer service. When asked exactly what service(s) he'd be performing as part of the check up, he looked shocked as if he'd never been asked that before then struggled to find the words. When at the end he indicated a part was needed and I asked what the part was and what the issue was, he actually said "how do I explain this". I'm well educated son, I'm pretty sure if you use English and explain it at a laymen's terms, I'll be able to understand.


Great Service, Great Team




Review of DiBiase Heating and Cooling Company

At this point homeowner is going to try and run an 18/8 thermostat wire from second floor to basement. We will then come back to re mount eco bee and make connections down at furnace.

Returned to site to further diagnose the Water Pressure issue. Was informed by Homeowner about issue with the Hot Water Pressure. Tested Hot Water Pressure at the Fixtures which was very low. Checked Water Pressure at the Water Heater which measured around 65 PSI. Lowered Pressure slightly to about 60 PSI. Turned Water Off at the Water Heater and drained the Water Heater. Removed the Tank Booster and found the Strainers were very clogged with Dirt and Debris. Installed new Strainers and repiped the Tank Booster Valve Back into the System. Turned Water Supply Back on. Tested Water Pressure at the Fisxtures and Measured Hot Water Temperature at 115 Degrees.We will follow up with an estimate for a Whole House Water Purification System.

When I arrived found circulator pump running and boiler firing, could also hear air in the lines. Homeowner has 5 zones all on zone valves. When I disconnect t stat wire from boiler it would stop everything. Found 4 older t 87 thermostats,and one slightly newer electronic thermostat. Disconnected all thermostats from wall and still continued to run. Issue is somewhere over at the zone valves, they are not very accessible. Homeowner just wanted to purge air out for now and shut off breaker. Purged air out of lines and re filled boiler to 12 psi.

Performed precision heat tune up on rudd gas furnace. Replaced 16x24x1 air filter. Checked all electrical conections and components. Checked manifold gas pressure. Performed combustion test. Cleaned flame sensor, and blew out all condensate and pressure switch tubing. Rudd gas furnace is working fine at time of service. Also homeowner stated that after the water heater was replaced in 2017, we also replaced the pressure reducing valve in 2017, that the water pressure has changed especially on the hot side . Took water pressure from bottom of water heater and it was 43lbs with no fixtures running. After turning on kitchen sink , water pressure dropped down to 36 lbs possible sediment or just a failed pressure reducing valve. Told homeowner it could be a possibility that everyone is experiencing a lower water pressure. Homeowner is going to talk with neighbors first before making a decision.
