3/23/26. Talked to homeowner about hot water issues. Found that the only time they have issues with the hot water is using the shower. Water will be hot then go cold and get hot again. Got homeowner to run kitchen faucet with no issues with hot water. Let homeowner know they will need a plumber to replace mixer. Also looked for any error codes in the history m no errors found. Also checked incoming gas pressure it was 7.5 w.c. And 6.2 w.c. When running. Lasers combi boiler is working properly at time of service.

3/20/26. Performed quality assurance on recently installed climate master geothermal system. Checked loop pressure it was 45psi very good. Checked temperature rise which was 18 degrees. Checked water loop temperature split it was 6 in heating mode. Checked all electrical connections and components. Duct work was sealed. Found that the geo airflow was correct. Explained to homeowner that it is a variable speed blower and will be louder when it fully ramps up. Also ran geo in cooling mode . Geothermal is working properly at quality assurance.

Swapped out old climate, master geothermal furnace with a new one and tied everything back in the way it was status quo

I arrived for a comfort issue with the oil, furnace and heat pump. Customers can’t get temperature over 65°, they have it set for 67°. I found the air filter was very dirty very fine dust. I recommended to the customer to change out the filter more regularly and to move to a merv 8 or 10 filter. They are using now is too restrictive. Collected fot my diagnostic system is running fine now making temp at 67°.

Replaced outside temperature sensor ( had to work around roofers). Re connected wiring inside boiler. Found there is no way of seeing the temperature on the digital board. Measured resistance and had right around 30,000 ohms which was good. Boiler is working properly at time of service.

Performed precision heat tune up on trane high efficiency gas furnace. Homeowner just replaced 413 air filter. Checked all electrical connections and components. Checked temperature rise. Checked gas pressure tested condensation pump. Cleaned flame sensor. Checked resistance of hsi. Performed combustion test. Gas furnace is working properly at time of service. Also provided estimate to replace water heater, inducer motor is kind of noisy on water heater.

When I arrived found circular pump running and none of the zone valves open. Traced out wiring and first thought something was wired wrong. In the end found that basement thermostat that is never used was turned up just enough to call for heat. ( this zone is valved off). Turned down thermostat and found that homeowner had turned it up. Explained to her that this zone is shut off. Also performed precision heat tune up on 2010 Columbia boiler. Vacuumed soot from heat exchanger and smoke pipe. Replaced Rf1 oil filter and nozzle. Performed combustion test. Circular pump is now pretty loud but still working. Provided estimate in case it fails oil boiler is working at time of service but would consider replacing due to age of boiler.

I arrived to the customers home to service there 1yr old Laars gas boiler. I started with inspecting the temperature and pressure gauge. I looked at the boiler for any water leaks around the whole system. I inspected the heat exchanger, the ignition system and the water drainage . I inspected the expansion tank and the water feeder and the circulator for proper operation. I tested for combustion and checked return and supply water temps . Everything is working fine at this time of service. Found during the check up that the summer weather sensor was engaging not allowing the hot water and boiler to run. I disconnected to test and the boiler will run like normal. I tested the sensor with my ohm meter and it’s shorted showing open no resistance. I left the sensor disconnected temporarily for them to have heat and hot water . We will order a new outdoor Laars sensor. I collected for 129.00 paid by check
