Jeremiah and Andrew did a really good job replacing our air conditioner and furnace. There are both hard workers. They found a gas leak in our system that we were not aware of and made the needed repairs. We are grateful for their diligence.

Silver club heater maintenance. Joe(JC)R 02/07/2025 Performed full system evaluation and safety inspection. I arrived to perform the customer’s annual heater maintenance. The customer didn’t have any questions. They weren’t interested in having the hot water tank flushed or the dryer vent cleaned. I then inspected the furnace. The heat exchanger was in good shape and the heater components were running well. The system is operating correctly at this time.

Jake Kring. 02-07-25. I arrived for a no heat call on a 30 year old furnace. I spoke with the homeowner and we checked the furnace and found that the systems control board is not sending 120V to the induced motor. The control board on not a type that has a universal board to put in its place. We discussed trying to find the part but the cost of the part and the availability of the part will be costly and a long delay. I recommended to replace the furnace at a minimum and we looked at pricing from the furnace only replacement and a complete system replacement with and without the free furnace special and financing. We decided to think over the options and let them talk when they get together in person to go over the options.

The customer didn’t have any questions and said that everything was running well. The customer wasn’t interested in having the dryer vent cleaned or the hot water tank flushed. I then inspected the furnace. The heat exchanger was in good shape and the heater components were running well. The blower motor capacitor was starting to get weak. It was at 17.1 and is rated for 20. This will place extra stain on the blower motor and wear it out quicker. The customer just wanted estimates for the moment.

Jake kring. 02-07-25. I arrived for a previous customer humidifier estimate and duct work estimate. We discussed how the noise throughout the home is loud at all return grills when the system cycles on. We wanted to see what it would take to increase the duct work to lessen the noise levels. This is a two story home and not all returns are accessible to where we can correct the duct sizing. I did recommend to replace all disposable filters with an electronic air filter and put one filter at every air handler to better filter the system and help drop the static pressures in all systems. We also discussed the humidifiers and that they have tankless water heaters. I explained how they would have to go with steam powered humidifiers to get the results they want with a home that is using tankless water heaters. I also explain that they will need an electrician to run power to the humidifiers and a plumber to get a water line to the humidifiers on the systems they want to install a humidifie

06FEB2025 Jason Brown Arrived for non club no heat. Spoke with Mary Henry about her systems performance. She explained that it’s just not heating. She had someone look at it and it worked until he left. We looked at the thermostat together then she showed me the furnace in the garage closet. Inspected the system and found the acid trap clogged preventing the pressure switch from closing. We then discussed repairs and decided to move forward with cleaning the trap. Disconnect trap from system flush trap out with cleaner and water. Blow out gunk with nitrogen then reinstall trap. Cycle heating on and off several times. Each time pressure switch closes and system lights. Discussed thermostat operation, and high limits. Helped Mary light her fireplace. System and fireplace are working properly. While out we decided to get signed up on a maintenance contract. Thanks it was super cool to meet you! I look forward to your first spring maintenance!

I informed the homeowner of the issue and we decided to order the part and it should come in tomorrow for us to pick up and come back out and get her heat running. Austin 2-6-25 I returned to repair/replace control board in Jake’s absence He gave me a rundown of everything going on and I made sure to pick up the correct OEM board and get it swapped out in the unit after doing so everything was coming on and working however, there was one minor issue, but that was only because the furnace had set for so long and the water had sat inside of the pressure switch long enough to cause it to have a fault. All I need to do was get the water out of it Which was very easy then plug it back in and everything came right back on and I made sure to turn it off and on through the heat cycle three times to ensure that it was comin

Jake Kring. I arrived for a new customer duct work inspection. I inspected the side of the home the customer is having issues with and the system it’s self. I do the system to be a 5 ton system with under sized duct work. The return side is a 12” and one 14” duct. The supply plenum tapers down to a 17” wide plenum. I explained the cfm needed for the system to operate and what the duct sizing is for the carrier system. I sized the new duct work for 15% compression and recommended to replace all the return duct and to replace the supply duct on the side of the home that she is having issues on. We decided to stay with one estimate on replacing the return duct and the supply duct only on the side of the home she is having issues on and leave the rest of the duct the same original duct. The rooms that she wants to address are the master bedroom and bathroom. The middle bedroom and the front bedroom and the bathroom between the front bedroom and the middle room.

Came out to perform preventative maintenance on furnace part of package unit. Discussed with customer regarding maintenance, filter, and any issues. Customer replaces the filter regularly, and doesn’t have any issues or questions at this time. Inspected blower assembly, blower motor, evaporator coil, heat exchanger, burners, flame sensor, ignition, gas valve, inducer motor and overall condition of equipment. Blower assembly will need to be cleaned, as it is acquiring build up on it. Metal plate behind inducer assembly has rust, but has been rusted for a little while now. Heat exchanger has wear, but there are no breaches in the heat exchanger at this time. Made sure customer had carbon monoxide detectors in the home, just for safety purposes. I checked thermostat operation, wiring, amps, temperature rise and gas pressure. Adjusted gas pressure to meet data plate requirements. Furnace is heating within manufactured specifications at this time.

Came out to perform preventative maintenance on furnace. Discussed with manager about maintenance being performed, filters, and any issues. Manager stated that he started in October of last year, and isn’t aware of any issues. I changed all 5 20x20x1 filters in the building. Inspected the ductwork, blower assembly, motor, electrical components, heating components, evaporator coil and heat exchanger. System internally is getting dusty again. We cleaned the blower assembly and coil last time we were out, and those don’t need thorough cleaning yet. Asked manager about their air compressor and he gave me permission to use it. Cleared fine dust out of burner cabinet and blower cabinet with compressed air. Cleaned flame sensor as well. Checked operation, amps, temperatures and gas pressures. Found a couple of the returns dampered off at the plenum, so I opened it up to allow more return air back to the unit. The return by the shop door was the dirtiest because it’s pulling most of the air. A

Austin 2-5-25 Completed the furnace tuneup on the American standard 80% gas furnace. Going through the system, thoroughly and checking all of the mechanical parts on the system to ensure that is running to the manufactured standards that it should be during today’s visit I did not discover any issues with the equipment. Everything was running great, and running exactly how it should, which is always a good thing I did clean the flame sensor and clean some of the debris outside of the Furnace and around the combustion chamber and I also replaced the filters and cleaned off the grills for the homeowner so that the debris on it will not fall down and make the filters dirtier so all of that being clean and testing a pressure differential and temp rise was all coming back with flying colors so as of now, the equipment is working great and they should not have any issues with the heating side of the equipment .

Jake Kring. 02-04-25. I arrived for a silver member fall tune up. I spoke with the homeowner and she showed me the LO of the indoor and outdoor system. I inspected the indoor system and found the blower wheel and return housing to be dirty. I checked the evaporator coil and found it to be fairly clean. I checked the systems gas pressure and found it to be set low at 3.3 IWC and the systems recommended range is 3.2-3.8 IWC. The systems static pressure is running at 0.5 IWC and the max static per manufacture range is 0.5 IWC. The O2 reading is high due to the low gas pressure. The gas pressure is within manufacture ranges per the data plate but the static pressure is high and this reflects a dirty system and or duct work and undersized duct work. The system is running and operating at this time but is not running efficiently due to the system’s dirty conditions and duct sizing.
