Isaac was great! He was thorough and polite and answered all my questions. He did a complete inspection and changed the filter for me, and then offered to help with anything else I might need, like changing smoke detector batteries or light bulbs. This isn't the first time a tech from Interstate has done that. I've used this company for years and highly recommend.

Call back. Joe(JC)R. 01/22/2025 I arrived and found that a plug had been pulled free when I was picking up yesterday. I made sure that everything was running well.

21JAN2024 Jason Brown Arrived for a call back on recent repairs. Spoke with tenants about the systems performance. They explained that the system would not heat all morning, but this evening it started working. I cycled the heater and found water inside the inducer housing. I allowed the system to run until it could no longer close the pressure switch. I then inspected the Acid trap and found the trap mounted improperly and rusted. After inspecting the acid trap I set up my shop vac and cleaned the drain lines again. Spoke with homeowner they bought the property this year, so there is no history on the equipments performance. After clearing the drains again system still builds up water recommend replacing the Acid trap and running heat tape with the condensation line. The heat tape is a preventative measure to keep the lines from freezing but has nothing to do with the current issue. I will call you tomorrow with pricing for the trap.

3 systems blue shield club heater maintenance. Joe(JC)R. 01/21/2025 Performed full system evaluation and safety inspection. I arrived to perform the customer’s annual heater maintenance. The customer didn’t have any questions. There are 3 systems. We only have access to 2 of the thermostats. The system that we can’t get to its thermostat was running so I was able to inspect it easily. I fully inspected the furnaces. The heat exchanger was in good shape and the heater components were operating correctly at this time. The systems are operating correctly at this time with the exception of a thermostat with damaged display that they want to leave for now.

Tom M. 1-20-25 no heat. Tenant stated she recently moved in and the furnace is not heating. Found water in the drain pan, you can hear water in the collector box not allowing the pressure switch to close you can also water over spilling from the trap due to the drain being clogged. I advised the homeowner quoted for the repair and she told me to fix it. I cleared the drain line removed water from the pan, I allowed the system to run for over 30 to 45 minutes . It’s draining at this time. The line is armaflexed and terminates in the garage closet I saw no evidence of ice. If problem persist a trap may need to be ordered. The current one is glued in and cannot be removed to clean. I

Jake Kring. 01-20-25. I arrived for a recall on a humidifier. I spoke with the homeowner and found that the system has been leaking water and the humidifier pad was not getting wet. I inspected the unit and first found the pad to have been installed upside down. The system was running and we only seen water on one small part on the front of the pad. Once I corrected this issue is then reassembled the system and found the drain port to be cracked and was leaking a small amount of water. We will be ordering a new drain spud and I left the water off at this time until we can get back with the new part to get this system running again. The homeowner was going to try and rig something up and turn the water back on to the humidifier with what ever drain line he works up. I let him know that I left it off due to the system not being able to drain and prevent it from running water everywhere but he was going to try and rig it up at this time.

Jake Kring. 01-17-25. I arrived for a club member noise issue on a system that is heating. I inspected the furnace and found the systems induced draft motor to be making a humming grinding noise. I checked the amp draw and found it to be over amping and the motor is too hot to touch. I informed the homeowner of the issue and we discuss the repair or the replacement of the furnace due to the cost of repair and the age of the system. We decided to replace the furnace this Monday morning.

Austin Z.
Austin 1/15/25 Completed the furnace tuneup on the carrier unit after going through the system thoroughly checking all of the parts. I did discover that there is a bad flame sensor in the unit and a gas leak on the shut off valve for the gas portion and on the blower motor, the capacitor was out of range, but everything else was good Mechanically on the system so I gave these options to the homeowner about taking care of them today so that he doesn’t have to worry about it or so they don’t get worse and he agreed upon doing them so I went through and completed all of the repairs for him and even got the hot water tank relit after I shut off the gas to the home Because the furnace and hot water tank are the only two appliances that use gas in the whole entire home so after finishing the repairs, I turned everything on to recheck and make sure everything was gonna work and it certainly did no further issues on the equipment during today’s visit And all of the filters are changed by th

Jake Kring. 01-15-25. I arrived for a club member no heat. I spoke with the homeowner and found that the system is working now but only after turning the breaker off and on. I inspected the two zone system and found the system to be running in both zones. I tested the system in low and high stage heat on both zones and found the static pressure in low heat to be 0.62 IWC and in high heat to be 0.94 IWC. The max static pressure that the system is allowed to produce is 0.50 IWC. I found the system to run in all modes and have no faults at this time. I informed the homeowner and explained that a system with high static pressure will cause the system to retain heat and can over heat the system to fault out on night temperature limits switches. If this happens three times the system will go into a permanent lock out and will need to be reset. This is what I suspect happened before the homeowner turned the breaker off and on. I let the homeowner know that if it happens again within 30 days t

14JAN2024 Jason Brown Arrived for two system red club tune up. Spoke with homeowners about the systems performance. They explained everything is working fine, however they recently had some water damage and want to be sure it won’t happen again. I inspected both systems in the attic. I checked through all electrical connections and safeties. I inspected the heat exchangers, blower wheels and evap coils for dirt dust and debris. I found both clean and working well. I adjusted the gas pressure down to 3.5 on both systems and found the heat rise within manufacture design. Checked all ductwork connections. Both systems are heating properly at this time. My only advice for preventing further damage is not not store things on top of the drain lines.
ISAAC J.
Came out to call to check a system over that customer had concerns about initially, but customer had fixed the issue. Customer had the roof redone last year and the roofers had to move the flue vent when doing the roof and didn’t reconnect it properly. Customer was able to get the flue situated back on the adapter and metal taped it. He just wanted the system looked over and make sure the system is working properly. He stays on top of the filters and didn’t need them changed. I checked the blower assembly, motor, capacitor, electrical components, heating components, evaporator coil and overall condition. Cleaned flame sensor and dust off the burners and components. Checked thermostat operation, amps, temperatures, pressures and carbon monoxide levels. System is heating properly at this time. Customer signed up for maintenance plan and used today as their first service.
ISAAC J.
Came out to perform preventative maintenance on 2 furnaces. Discussed with customer about maintenance being provided, filters needing changed and any questions she might have. Customer stated that she believes she is due for the duct cleaning that’s included in here maintenance plan. Told her I would have the office contact her for scheduling. Changed out all filters for customer. Inspected the blower assemblies, motors, electrical components, heating components, heat exchangers, evaporator coils and overall condition of equipment. Cleaned flame sensor and dust off the components. Checked thermostat operation, amps, temperatures and gas pressure. Both systems are heating properly at this time.
Austin Z.
Austin 1/13/25 Completed the furnace tuneup on the carrier equipment. During the visit, I went through the system, thoroughly to check all of the mechanical parts on the equipment to ensure the functionality of each part of that system and throughout my check up, I did not discover any mechanical issues with the equipment everything was in range on my voltmeter, and everything was in resistance. However with further evaluation of the equipment I did discover there was some debris and buildup getting inside of the primary drain on the furnace since this is a 90% condensates during the heat and AC season so all year long it will do that and at some point it has backed up and water to get into the drain pan underneath the system which overtime it does rust, and with enough rust and water that water will actually start seeping through that pan itself, which will start getting on the wood and then sheet rock and cause damages and I never want a homeowner to to deal with that so I did bring
Thomas M.
Tom M. 1-13-25. Silver club furnace maintenance. Replaced air filter customer provided. Cleaned flame sensor and electrodes. Blower capacitor is weak reading 13.7 rated for 15. Blower motor bearings are starting to get loose. Set gas pressure to 3.5 inwc. Inspected the heat exchanger noticed no issues. Flue Co 5 ppm. Induced draft motor is at its max amp draw 1.0. Recommended upgrading the furnace due to age, efficiency and multiple components starting to fail. Customer stated he’s unable to do anything at this time.
Austin Z.
Austin 1/13/25 Completed the furnace tuneup on the American standard furnace equipment as I went through everything on the system to verify that is all working good the homeowner was outside in the garage, watching as I was maintaining the equipment and during the visit there was no issues present during today’s check up I only adjusted the gas pressure which is a very common occurrence which now that it is adjusted and working better. Everything on the system should work just fine this winter I even went inside and turned the thermostat back on to make sure everything was going to kick on for heat, and it certainly did , just like I knew everything would but at the end of the visit they did not have any questions or needed anything else which I said my goodbyes and that ended today’s tuneup. The homeowners also change the wrong filters and they did it recently and they also buy and provide their own filters for their home filter. Changes was not needed during today’s visit.

Jake Kring. 01-10-25. I arrived for a previous customer no heat call. I spoke with the homeowner and found that the system was not heating yesterday but the system has met its thermostat set point of 72 deg at this time. We inspected the system together and we checked all electrical components, gas pressures, static pressure, temperature rise and cleanliness. We found that the system was operating close to the correct gas pressure and I dialed it in to 3.5 from 3.2 IWC. We also found the temperature rise to be 32 deg and the static pressure to be 0.8 IWC. I explained how the system is designed to operate within the systems manufactured specifications and we compared the systems reading to the real time readings we were seeing in the system. We discovered the system to be undersized on supply and return duct. We inspected the return filter and found it to be howling as the system runs and the filter has turned into a bowl due to the system trying to breathe. We removed the return filter

Austin 1/9/25 Completed the furnace tuneup on the 90% comfort maker furnace. During the visit I went through the system thoroughly to make sure everything was running how it should during the operation of heat and as I went through my check up everything passed the test and was working how it should nothing was out of range or getting close. As of now we have done a good job of taking care of the system and cleaning it up and testing it to make sure the customer won’t have issues of comfortability in the cold weather, so as of now, everything is working good I did mention that the coil could use a secondary safety switch since there is only one in the pan and water has backed up out of the secondary at some point in time and to prevent that pan from rusting out and water dripping through or other issues having another safety switch would be good for the system and safety of the home but as of now the homeowner wanted to wait on doing so, and will periodically look at the furnace to se
