Onsite today for a no heat service call on a Lennox furnace. Diagnosis was giving an error code 311 which indicates air flow restriction. I have checked air filter which was recently changed. And upon further review I have found white mesh type filters within supply vents, which this can cause restriction at supply duct work. I have removed all mesh material and system has been running normally with a 45 degree temperature differential in heating. I have cleaned flame sensor as well. Job Complete.

Rheem Furnace Installed in 2002 - Maintenance Upon arrival, furnace seemed to to be pretty clean as far as dust and debris was concerned. After starting the maintenance , it was discovered that the blower motor is completely caked with dust and debris , and the motor itself is leaking grease and oil and should be replaced sooner than later. Inducer is over amping, and water spots in filter box indicates a freezing and leaking coil. 20x25x1 filters needs replaced, none onsite. Cleaned cabinet, flame sensor and burners today. Furnace is only hitting 1ppm on carbon (nothing to worry about now, but issues are arising) I quoted a blower motor replacement, but I also sent furnace and air conditioner replacements. One of the quotes is for a high efficiency system that will be mandatory after 80% stock runs out in Colorado per the new Colorado Clean Air Act effective January 1st of this year. We are allowed to sell out of stock, then high efficiency equipment is mandatory. Full report sent

He didn't service anything. I got another company to come and service my furnace. It was too small for him to bother with. He quoted me a +$600 to service and clean my furnace or $1400 price to clean my furnace and clean my ducts. The other company came adjusted my gas pressure to get better efficiency with less wasted energy. I think I called the wrong company. 12/16/25 just a note to say this company heard what I was saying and responded by refunding what I paid them. I appreciate this because I ended up hiring another company. Thank you.
