Customer stated she wasn’t sure how long it’s been since the filters were changed, so I said that I would check them. Inspected and changed filters for customer. Inspected the blower assembly, motor, electrical components, evaporator coil, drain and overall condition of equipment in closet. Washed condenser coil thoroughly and inspected the internals of the AC. Checked operation, amps, temperatures and pressures of AC. System is cooling properly at this time.

Jake Kring. 10-11-24. I arrived for a water leak issue for a previous customer. I spoke with the homeowner and started to show me the indoor utility closet in his garage and show me his drain line and water heater. I informed the customer that there is a diagnostic fee and we discussed what it covers and why he had us out today. He had a drain line that was leaking and had damage to his home from the water leak. I informed him of the cost and that he has not had us out for him maintenance for a year and that the system was installed 11 years ago. I did notice that the water heater was newer and let him know someone could have cut the drain line to replace the water heater and that there is no telling what has been done to the system when he has not had us out to inspect the system as it should be from year to year. We decided to not touch the system at this time and he will save his money to address the repairs on his home.

Jake Kring. 10-11-24. I arrived for a blue club maintenance summer tune up. I spoke with the homeowner and she shows me the location of the 32 year old system. I first replaced the filter and inspected the indoor system and found the evaporator coil drain pan to be siliconed in place and the system to be corroded and the system to have a layer of dirt in the blower wheel and coil. I found the blower motor to have been replaced but the capacitor to already to be getting weak. I inspected the outdoor heat pump and found the system to be running and cooling well. I explained that the new motor and capacitor are getting weak due to the undersized duct work on this 3 ton system. I explained that the best option to for the system to run would to be putting the system in the attic and addressing the undersized duct to let this system run more efficiently and have shorter run cycles. We bid a system with all new duct work and to bring the system up to code but we are not ready to move forward.

She showed the the location of the thermostat and the furnace closet and where the condenser was located. I first removed the filter and cleaned the condenser and the washable filter. I then checked the furnace operation and found the capacitor to be reading under the manufacturer range of operation. I then inspected the condenser and found the condenser to be running but the capacitor in the condensate was also weak but running. I cleaned the condenser coil and let the homeowner know the issue with both the indoor and outdoor capacitor. I explained to the husband what the capacitor is and how it operates. We decided to replace both capacitors and he used his $25 gift card for this preventative repair. Once I replaced both parts I cycled the system back on and checked the systems electrical components and refr

Came out to call for a system not cooling well. Customer stated that the system was freezing up again, and the unit was running a lot. Told him I would check system over and see what needs to be done. Cleaned electrostatic filters out and let them dry. Checked system over and found the unit running low on refrigerant again. Discussed with customer about options in regards to leak searches and possible repairs. Customer wanted to look into doing a leak search in the spring time, and charge system again for now to get it operational for the remainder of the warmer weather. I added 2lbs to system to get pressures back in range. Informed customer on rerouting copper line set if that was the issue and what avenues we could go with that. Customer will call us back out next spring to check for a leak.

Jake Kring. 10-08-24. I arrived for an inspection on a furnace. I spoke with the homeowner and she explained to me that the light in the furnace was orange and the warning sticker was orange. The sticker said to have qualified technician or approved personal work on the system. I had to explain that the color of the light and the color of the sticker has nothing to do with each other and it doesn’t mean that the system has a warning. I showed the homeowner that the light in the system flashes when the system had a breakdown and the flash code helps us diagnose the system when it fails to operate correctly. We decided to preform a tune up on the system and I showed her that the system is running correctly. It’s 85 degrees in the home due to her shutting the system off when she seen the light and I ran the furnace for 30 minutes to check the systems temperature, gas pressure, amps, volts and other components of the system. I found no issues with the system. I did adjust the gas pressure

Jake Kring. 10-04-24. I arrived for a new customer no cool call. I spoke with the customer and found that the system is a 11 year old system and is running inside but not outside. I inspected the indoor system and found the filter to be in need of replacing but the electrical components to be running well. I then inspected the outdoor system and found that the system is in need of cleaning and the compressor and condenser fan motor are over heating. I found the capacitor to have completely failed and was causing the issue. I explained my findings and let them know it needs to be cleaned. I could not clean the system due to the water port leaks inside when I tried to use the water hose to cool the system off and clean the system. We agreed to replace the capacitor and see if the system will come on and run. Once the part was on I cycled the system on and found the system to come on and run. I checked the systems amp draws and refrigerant charge and found it to be running at 8.9 out of 1
