Great service under warrantee

Called Dibiase in the morning - Kurt and crew were here to fix leak and were finished PDQ with report and invoice ($0) issued by 2.15pm. Kurt took the time to explain the issue and what corrective action they had taken. Can't ask for better.

Matt is settling on the home in 2 weeks and looking to ensure system s are designed and installed properly and looking for energy savings solutions. Reviewed all of the systems in the home and highlighted several areas that were recommended for improvements.

Reviewed equipment in attic space ,9 year old Trane Tam air handler with 9 year old 16 seer ac unit. Measured all equipment to provide estimate. Looking for Cooling only options. Inspected wiring to outdoor unit, found broken wire to contactor from fan motor. Temporarily fixed wire to test. Found when unit started, suction pressure went below 40 psi for a second which caused contactor to jump off and on, when this happened the compressor reversed rotation. Bypassed pressure switches to test and checked system charge. Charge is good on unit . Left system to cool without pressure switches in the circuit. Recommend replacement and not repairing pressure switches at this time. Proposal will be emailed.

Reviewed expectations with Bob and current situation with home and importance of health and safety. Looking for HE solutions for air filtration and air scrubbers for whole house for 2 systems. Also would like proposal for air sealing and insulating the attic space. The outside walls are being spray foamed from the outside and the rim joist were spray foamed.

Performed QA on Bosch Heat Pump/Coil install on an existing oil furnace. Homeowner had questions about the scheduling features and the reminders on the thermostat. He said their was an alert the other night for Aux Heat running above 35 Degrees. Found his sleep temp set to 64 and awake temp set to 68. This 4 degrees is over the 2.9 Degrees Auxiliary Heat droop. We went through and adjusted the sleep temperature to 65 degrees to help alleviate the oil furnace from running. Also adjusted the hold setting so it was following the schedule instead of a permanent hold. Tested system in heat pump and turned the Auxiliary Heat on to make sure the oil furnace would run. Tested ez trap safety and filled condensation pump. Completed checklist form in system. No additional follow up needed.
