Know your equipment
Figure out if it's a Lennox equipment problem or just a room control issue.
Lennox got home heating and cooling gear, mini-splits, thermostats, and zoning. If only part of your house ain't comfortable, tell us which rooms or zones got issues. Let us know if the thermostat changes like normal and if other rooms still get air, instead of just thinking the outdoor unit need to be replaced.
If you got a Lennox system with a few thermostats or indoor units, figure out which control goes with the area that’s having trouble. Write down any alert just like it shows up. If you’re thinking about getting a new system, talk about which rooms are hard to keep comfy and how old your current equipment is.
Equipment to identify: Air conditioners, furnaces, heat pumps, mini-splits, thermostats, and zoning controls.
Manufacturer resources
Use the official info for your model.
Check the equipment model, serial number, install date, and registration papers before looking at coverage. A manufacturer link doesn't mean a repair, replacement part, or labor is covered. Double-check the terms that apply to your equipment.
For help from the manufacturer, use the company contact below. Have your equipment or part’s model, serial number, when you bought or installed it, and proof of purchase ready. What’s covered and how to file a claim depends on the product’s terms.
