Came out to call to recheck system and verify issue. Customer stated that the electrician needed to have the unit removed to access the electrical, but then stated it could be the thermostat. I checked system over and did come to the same conclusion about improper power to the unit and it causing issues with the relays inside the system. The thermostat was not the cause of the problem. Explained to customer about the issue and what’s needed to resolve it. Customer wants us to come back out Monday to pull the unit, so the electrician can fix the power problem, and then we will reinstall it. Dec 9, 2024 Isaac & Andrew Came out to pull a pancake air handler out of a closet space to allow an electrician to fix the main voltage issue. Pump down AC system and then disassembled the air handler. Allowed time for the electrician to come and fix the problem. Came back and reinstalled the air handler back in place. Brazed line set back in and pressure tested unit. Ended up finding a leak in the

Came out to perform preventative maintenance on furnace for customer. Discussed maintenance being provided, if filters needed to be changed, and any issues customer may be having, if at all. Customer stated he changed the filters this week and so far the system has been running fine. I inspected the blower assembly, motor, electrical components, evaporator coil, heat exchanger, heating components and overall condition of equipment. Found heat exchanger to have some hot spots, but no breaches detected. Cleaned flame sensor and dust off the burners. Checked operation, amps, temperatures and gas pressure of both stages of heat. Customer doesn’t use the humidifier anymore and doesn’t want to have it operational. System is still heating properly at this time.

Jake Kring. 12-06-24. I arrived for a no heat call referral from friends and family. I spoke with the homeowner and she showed me the location on the system and I found it to be a natural draft furnace in the attic that is feeding the duct work in the slab. I informed the homeowner that we cannot get parts for this furnace and that I recommended to replace the system. We discussed the system and agreed to replace the return duct and plenum and reconnect the duct in the wall. The new system will have a 10 year parts warranty and a 1 year labor warranty. I explained that we will be hanging the system to get it off the cycling and be putting a new drain pan under the unit. We also discussed the line set and that it will be ran outside of the home to the condenser and it will be exposed.

I first inspected the home and duct work and sized the home per the existing system size and what sizing the home would need if we ended up replacing the system and duct work with removing the undersized system and duct work. We went over the details of the duct work with and with out the system replacement. We went over all guarantees and the life time warranty on the duct work. I explained our 10l% satisfaction guarantee that all rooms will be equal per every room air flow and CFM requirements per the system and size of home. If it’s not correct and we have one or more rooms not keeping temperature we will correct the issue at no additional cost. We went over the apples to apples guarantee and I explained that we will preform the same work and quality with the guarantee. All work will be installed per local and state code.

Came out to call to perform preventative maintenance on furnace. Discussed with customer about maintenance being provided, filter, and any questions she may have or anything I can help her with. Customer asked if I could clean off the register in the kitchen. It had some grease residue on it, and customer would like it cleaned. Customer gave me a hot rag and some cleaner and I removed as much grease as I could. Recommended customer have all the ducts cleaned out as soon as of the others had some dust build up on them a little bit. Customer will look into having them cleaned in the spring. I inspected the filter, blower assembly, motor, electrical components, heat exchanger, evaporator coil, heating components and overall condition. Cleaned flame sensor and dust off the burners and components. Cycled furnace on and checked amps, temperatures, and both stages of gas pressure.
