Another great visit.

Chris came to service our new heat pump for the summer months. He gave the same professional care as the installers; answering questions and providing helpful tips. A pleasure to deal with DiBiase.

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.
