A gas furnace is the one piece of home equipment that burns fuel inside your house, so furnace work is safety work first. Air 911 Heating and Cooling LLC covers both sides of it: furnace repair and maintenance when the heat goes out or the system starts acting up, and furnace installation when the unit has reached the end of its service life.
Our technicians hold gas appliance certification and NATE certification, with factory training and carbon monoxide safety expertise. Every repair and every tune-up includes combustion analysis and a multi-point safety check, not just a filter swap.
We install Armstrong, Rheem, Lennox and Trane gas furnaces and service the rest. As an Armstrong ProTeam Dealer we have factory support behind the equipment we put in.
Pick the service that matches your situation, or call and we will point you to the right one.
No Heat, Short Cycling, or Ignition Faults
Ignition failures, flame sensor problems, blower motor faults and limit switch trips. We work through a systematic diagnostic sequence, then verify the fix with combustion analysis and safety control testing before we leave.
Furnace Repair & MaintenanceReplacements & Efficiency Upgrades
Heat loss calculations, gas line capacity verification, venting analysis and ductwork inspection before installation day. We explain the difference between 80 percent, 90 percent and 95 percent AFUE equipment and what each means in this climate.

An 80 percent AFUE furnace uses proven technology, costs less up front and vents through a metal flue. A 90 percent or higher furnace uses condensing technology, vents through PVC and costs less to operate. Higher efficiency equipment suits Chattanooga well because our heating season is milder.
We install Armstrong, Rheem, Lennox and Trane gas furnaces, and we are an Armstrong ProTeam Dealer. We service most major furnace brands no matter where you bought your system.
A furnace that has been inspected, tested and correctly installed is not something you should have to think about. Air 911 Heating and Cooling LLC handles the safety side and the comfort side of gas heating for homes across the Chattanooga area.
