Performed QA on Trane Heat Pump/Air Handler installation. Reviewed installation with homeowner. She had questions about using the Schedule feature on the thermostat. Went through with her how to setup the schedule. Also reviewed with her how the heat pump operates and when to switch it over to the oil boiler in the winter. There old system was a straight AC. Tested wet switch and ez trap safeties. Did not find any signs of water in the drain pan. While testing system, found a lot of Oil around the suction line under the insulation. I soap tested the Lineset connections and did not see any leaks. Refrigerant charge was good as well. This could have been oil from during the install. Also there are only 2 Wires going to the outdoor unit. If there is ever a communication issue we will need to try to run a new thermostat wire to the outdoor unit. Both of these things are for us to monitor, no follow up is needed.
Taking measurements to prepare a Spray foam insulation estimate for the attic.
No ac, found system off upon arrival asked customer to turn the ac on, noticed compressor does not start. Check capacitor Reding very low, tried installing new capacitor still did not came on, tried hard start assist and compressor started, customer does not want to spend any money in this current system, would prefer system replacement option, home comfort consultant to come out on Monday between 1 and 3 pm
Performed heating maintenance, replaced air filter. Cleaned burners and flame sensor, inspected heat exchanger. Blew out condensate trap and drain. Serviced humidifier, cleaned and replaced water panel. Started humidifier, checked operation and set humidistat to 35%. Checked voltage, amperage and electrical connections, measured capacitor values. Started gas furnace, tested limit and safety switches. Performed combustion test. Checked operation and temperature rise.
We over System with bob and after tracing everything found that the next step is to located the zone valve for the nursery area to see if it is operating correctly. Also old computer system that runs the entire system may not be programmed correctly, bob will try to locate the zone valve and test it to see if it needs replaced.
Performed heating maintenance, found condensate pump has a broken discharge housing where the fitting connected to. Replaced condensate pump, tested pump. Cleaned burner and flame sensor. Inspected heat exchanger. Blew out condensate trap and drain. Checked voltage, amperage and electrical connections. Started boiler, checked boiler pressures and temperature. Tested limit and safety switches. Performed combustion test.
Performed heating maintenance, cleaned ignitor and flame sensor. Blew out condensate trap and drain. Checked voltage, amperage and electrical connections. Cycled circulators started boiler, tested limit and safety switches, measured fuel pressures. Performed combustion test. Checked boiler pressure and temperature. Need to set up an appointment for a ductless mini split for the basement.
Relative Humidity exceeds 55% during demanding days. even with AprilAire Whole home dehumidifier. Monitored Relative Humidity/Indoor return wet bulb throught my time at the house. %RH did not exceed 52%. Wire R, C, and G from equipment to DEHUM control, following install manual. ( Prevents outlet air from entering inlet of dehumidifier). Will make comfort consultation appointment with Joe to attempt to give a definitive solution to humidity problem. (Second attic AC system or another Whole home dehumidifier).
Return visit to perform combustion test on boilers 2 and 3, check gas pressure incoming and manifold pressure, incoming is 5.8 wc burner can’t be adjusted at this time firing rate should be equivalent to 4 inches water column, customer need to contact peco to increase gas pressure so we can get 4 inches water column on manifold side to archive the 200 k btu firing rate there will be an extra charge for next visit
Performed cooling maintenance, checked air filter ok. Blew out condensate trap and drain. Checked voltage, amperage and electrical connections, measured capacitor values. Started air conditioner, checked refrigerant charge and temperature drop across coil
Checked no cooling complaint, set thermostat to cooling, started air conditioner, checked air filter, blew out condensate trap. Checked refrigerant charge ok. Checked run capacitor. Found a failed hard start kit. Replaced start kit. Cycled air conditioner. Checked operation and temperature drop across coil.
