Completed PECO Tune Up. Equipment 3 Ton communicating Carrier Heat pump with 20KW electric heat kit. 18 years old Homeowners said electric bill $600+ dollars. However when they talked to previous homeowner they confirmed that this was the average bill. Carrier thermostat does have the option to run “Heat Pump only” as well as “System Control” and “electric heat only”. There is no way to set outdoor temp lockout for electric heat. Controls are carrier communicating. I cannot offer Ecobee or smart thermostat as they are not compatible. Setting thermostat to “heat pump only”will result in some savings. There is no drain protection. Left email estimates. Left email estimate for intermatic surge protector for outdoor equipment circuit and ECM surge protector for blower motor. Bypass humidifier damper is missing which is needed for summer. Left estimate. There is a propane furnace with AC for master bedroom area. (added as an addition to house in 2008). Temperature rise in heat pump

Homeowner explained that noise was coming from expansion tank whenever water had been running and was shut off. Homeowner also mentioned that his water pressure some time last week in the morning was very low but returned to normal in the afternoon. There is a possibility that the municipality has been adjusting water pressure. I did not observe noises while on site. We tried to recreate issue by running water from multiple taps. Water heater air side is still at 80 psi. Expansion tank has not failed. Checked water pressure 85 psi. Considering that 80 psi is still high for water pressure I left estimate for domesticated pressure reducing valve. As I was leaving the noise happened seemingly randomly.
