Review of Interstate Heating & Air Conditioning

Technician Joe R. was really conscientious and explained that the blower wheel for the furnace couldn't be cleaned properly without removing it from the housing. He tried cleaning it while inside the housing but not done to his satisfaction. He called before proceeding because it would be labor charge to remove the wheel. I agreed with Joe that this prevention would keep the furnace running perfectly and help prevent problems later. Not everyone would take time to see that something is done right. I was very satisfied.

Came out to perform preventative maintenance on heat pump system. Discussed with customer about maintenance, filters, and any issues. Inspected air ranger filter, uv bulb and HEPA filter. HEPA filters will need to be changed in the attic, and we need to order more air Ranger filters for customer. I let customer know that we will order all filters needed and come back to replace them. I inspected the blower assembly, heating elements, wiring, and overall condition. Cycled emergency heat and checked amps on heating elements. Checked heat pump operation and pressures. Overall system is operating properly at this time.

Jake Kring. 02-13-25. I arrived for a 21 year old infinity furnace tune up. I spoke with the homeowner and found that the system has been running well but they keep the temperature low at night and turn the system up to 67 deg during the day. I inspected the system and found the return grill to be missing and the blower wheel and coil to be in need of cleaning. The system will cycle on and run in heat normally. The drain on the fur is clear and moving water without any issues. I informed the owners daughter to plan on replacing the system and get it filtered correctly to keep the system running well. I also recommended to replace the system due to age and cost of repairs and cleanings. They wanted to let the system run for now and not do anything to get the system clean at this time.

Austin 2-13-25 Completed the furnace tuneup on the carrier 80% downflow system. During the visit, I went through the system, thoroughly checking all of the mechanical parts even with the homeowner outside with me he was even able to see all of the things I was checking and doing and threw my analysis of the system to ensure that it has the best functionality as possible. Everything passed the test as it should, and no reason to repair any parts or be concerned. As of right now everything was running how it Should, I did clean up inside the furnace a little and adjust some of the gas pressure on the gas valve but outside of that nothing else was needed. I didn’t even need to really clean the flame sensor but I did during today’s visit anyways just as a precautionary, but all in all the system is running great, and it is holding temperature inside the home very well . I got to meet the homeowner Jeffrey and he was a very nice man and it was a pleasure to meet him. We were able to tal

Jake Kring. 02-11-25. I arrived for a club member duct work estimate. I inspected the system and found the unit to be a upflow in a hall closet. I sized the air flow to all rooms and bid to replace the duct per the correct air flow to all rooms. The homeowner wanted a bid to leave the same size duct in place and not to replace the grills or supply boots. I explained that there will be no comfort guarantee if we only replace the duct with what size is already in place. They wanted to go over both estimation and see what they will want to replace the dust work with.

I found the thermostat set to 68 calling for heat, and the system idle. Inspected furnace and found it locked out. I reset the lockout and the system cycled into heating. I checked all amps/ and motors. Verified evap and blower wheel are clean. Tested safeties for weak or loose connections. Checked gas pressures and heat rises. All pressures and heat rises are within manufacture specs. Discussed findings with homeowners. We decided to leave it be for now and to call in when/ if it stops again to catch what is going on. As of now the system is working properly at this time. Thanks!

Jake Kring. 02-07-25. I arrived for a club member tune up X2. I inspected the downstairs system and found the blower wheel to be dirty and the system to have a good amount of biological growth in the air handler. I checked all electrical components and found the system to be running on 10 KW and all electrical components to be running but the system shows a lot of age and rust. I then inspected the upstairs system and found it to be in the same condition but one set of the heat strips are not operating as it should be when the heat comes on. Only half of the heat is working. This system is also dirty and needs to be disassembled and cleaned to get the blower wheel and housing to move air better and more efficiently. This system also has a good amount of biological growth in this system and both units could use a air scrubber and/or a UV light to help keep the system from having a buildup of bacteria and to keep the systems clean and functioning better. I recommended to think about repl

I adjusted down to 3.5 which it what the gas valve calls for. The system is operating correctly at this time.

Completed the install of the recommendation to the homeowner. They decided to do the air, scrubber and duck cleaning but as of today’s visit, I installed the air scrubber for them and show them how I was exactly going to get it all installed and wired in after doing so they saw that the light from inside the supply was shining through the coil a little bit where they could see it then I was able to reseal the coil up, showing everything working and got the system, turned on and circulating air as it should, no issues as of right now everything is currently working how it should and as of now the air scrubber is doing his job and 24 hours from the exact time it was installed it will be working at 100% efficiency.

Jake Kring. I arrived for a new customer system replacement and a mini split install in the separate garage. We discussed the system and the filters and that she wanted a new filter. I looked the system over and we decided to bid a 95% furnace with a condenser and not go back with a heat pump. We also went over UV lights and how they benefit the system. We decided to add a new filter base in the utility closet and to ass a IAQ 3000 to the system. We also looked at the garage and decided to add a 18K mini split. I explained that both systems will have a 10 year parts warranty and a one year labor warranty. I will be following up with the homeowner this Friday.
