I did inspect heat exchanger there are lot of rust and build up. Collector box staring to leak water. Would recommend getting an estimate to replace system. I did provided estimate to come back and replace board. Customer will tall to Tony about system replacement.

I arrived to the customers home to look at a vent in the customers office. The Basement is getting new finished basement , and it’s all finished drywall double insulated. His vent isn’t producing heat . The dry wall will need to be removed in the bay to inspect the supply run out and damper for the arzel system . All the other vents for that zone in the basement are producing good heat .

When I showed up furnace display was “Idl” or idle. There are no active error codes. There are no error codes in the history. Aprilaire 413 filter was very dirty (drywall work being done in basement) After replacing filter I told Karl to make demand for heat from1st Floor Tstat and observed operations. System went to gas heat 5 min into heat pump run time after OAT dropped to 35° as designed. Checked temperature rise. System ran long enough to energize condensate pump. When we made demand for heat from basement zone (Zone 1) Arzel board displayed CL1 there. Basement thermostat was configured as a heat pump as opposed to gas funace AC. Reconfigured and tested. System operating well at this time. Told Karl to keep eye on drywall dust in filter and to limit run time as much as possible during construction of basement.

I arrived for a no heat. The customer had said he just replaced the igniter because he’s getting an error code for nine. I turned the system on it fired up and ran and then shut off within 10 minutes. It tried to start back up and gas valve would not open. I checked my low volts at the valve and checked my pressure on the outlet, I have 24 V from the board, but the valve is not opening. I hammered the valve with my screwdriver. The valve would open and start, but there’s no guarantee for how long the heat will run. Customer needs a new gas valve , I quoted 1111.83. The customer at this time did not want to pay me 50% on the valve. She wants to guarantee the valve will go in on Friday. Doesn’t wanna wait till Monday for $ 99 for tonight for diagnostic. I will follow up with the office in the morning to check availability and pricing on the valve.

Qa on gas furnace and ac. All complete and passed
