Upon arrival I found thermostat reading aux heat but very cold in house. Went to AHU and found system getting 24v to W but no aux heat. Went into Cool Cloud app and had to update software for control boards. Once updated, I enabled aux heat by selecting correct heater pack, 15kw. Once I applied changes the aux heat contactor pulled in, measured amps and operation. Aux heat operating normal. Went to HeatPump outside and found it was idle, called for HeatPump heat from thermostat and found only 1st stage running. Enabled 2nd stage operation on thermostat by reprogramming settings. Verified refrigerant pressures and temps for HeatPump. Set thermostat to normal temp and checked operation of both HeatPump and aux heat. Let unit run for some time because I wanted to see defrost operation. HeatPump went in and out of defrost normally, then back to heating. Unit operating normal.

When I arrive customer explain to me they are in process of closing on their home in the next two weeks. house inspector found some type of growth, mildew of some type inside indoor furnace at coils. I gave customer three options of estimates. Coil cleaning today while I’m here on site or scheduling out whole house duct cleaning and also, while I am here on site get inside furnace clean While coil is in place. Customer gave his wife a call to explain everything and ask if I can email the three estimates over, after a little while customer decide to go ahead with one of the options and that’s to mitigate the problem of cleaning the coils & inside of area. while I was here on site. After taking care of the job I ask a customer to take a look behind me to make sure everything was correct in sight to customer satisfaction.

Customer recently replaced the air filter. I checked the electrical wiring and electrical systems, all are within specification. I checked auxiliary heat strips. I operated the unit in heating mode #12 and confirmed proper flow rate and heat of rejection. Unit has 25-30 degrees temperature rise. Loop pressures are in recommended range. Unit operating normal. I replaced the humidifier water panel, cleaned the humidifier drain line and tested the solenoid valve that feeds the water to the panel. Humidifier is operating normal.

Upon arrival I spoke with manager and she informed me that they would like a quote to replace both condenser coils for rear 40ton unit. Previous company was out and provided quote, was given report, took picture and uploaded to file. Went to roof and confirmed it is rear 40ton unit that needs repairs, disconnect off. Circuit A low with oil in condenser fins. Circuit B flat, no refrigerant. Quoting customer to replace both condenser coils. Also was told od temp sensor isn’t working, as well as Comfort Link scrolling display. Including these in the quote to replace as well. We will need crane for coil replacement. Roof is about 20ft high, unit is about 50ft away from edge. Uploaded all info to invoice, office please follow up with formal quote to manager.

Upon arrival I was shown to indoor and outdoor units. Found HeatPump not rejecting much heat so I put gauges on and found very low suction and normal discharge. Shut off unit and inspected indoor coil to find TXV frozen. Left system off for a few minutes to let it thaw. Ran ac again and found high Superheat and low subcool. Added a few ounces of 410a and high pressure increased over 60psi in 10 minutes. TXV is not regulating refrigerant and needs to be replaced. Quoted customer and he called Home Warranty Company, I gave them information on equipment and cost for repair. Warranty Company declined repair and they said they would have to send their own tech out to confirm diagnosis because a repair cost that high needs to be done by their technician.

Upon arrival found auxiliary pan pinched by unit, water draining over side opposite float switch. Found condensate line kinked upward from installation approximately 3/4”-1” causing water to flow out of pan into auxiliary pan. Float switch mounted on high side of pan. Removed all water from auxiliary pan and moved float switch to low side of pan. DO NOT HAVE SUPPLIES to run new condensate line. Require another visit with supplies to remove old line and run new line with proper slope so water will flow out of unit. Visit scheduled for tomorrow 6-9-19 between 9 A.M. - 1 P.M.

I operated the unit on cooling mode and measured 20+ degree delta temperatures across the evaporator coil. I had normal refrigerant pressures and 8-9 degrees superheat. I checked the electrical wiring and electrical systems, all are within specification. I replaced the filter, the customer needs to pick up more filters. I cleaned the condensate pan and drain lines and ran hot water to flush the debris and to make sure it drained properly. I noticed that because it’s an up flow air handler there is no pan under the unit and no safety device so I recommended installing EZ Trap. I do not have one in the van to install now. I filled in a parts order form and customer paid $100. Unit operating normal.

During heating pm 2 years ago customer told me that the neighbor was having issue with the water freezing in the yard from the sump pump discharge and that the humidifier drain line was the only source of water filling up the sump basin. I tried restricting the flow with the ice maker valve then and it only slowed the flow when it was almost closed. Over time sediment or mineral build up made it where water would not flow through. I opened it up all the way. There is an orifice in the humidifier supply tube. Everything is operating normal except the humidifier does use a fair amount of water. The only viable solution I could find is to empty the condensate drain line into a pump and then pump it to the sink basin which drains into the city. I made an estimate for this but the customer does not want to change anything unless it really becomes an issue with the neighbor.
