Seguin sits on the Guadalupe River, and the water shapes its homes. Victorian and Craftsman houses downtown, river lots in McQueeney and Lake Placid, and farmsteads near Kingsbury all bring their own heating challenges.
Comfy Air AC and Furnace Repair has served Central Texas since 1986. We diagnose the real cause, explain it in plain terms, and fix only what your Seguin home needs.

Homes near the Guadalupe River in McQueeney and Lake Placid deal with damp air, and older downtown homes can have closets or crawlspaces that hold moisture. Over time rust forms on burners and cabinet panels, connectors corrode, and drain components clog, any of which can stop a furnace from firing or shut it down.
Our technicians look for the source of the moisture, such as a drain problem or poor ventilation, then clean or replace corroded parts and test the full sequence. We explain what caused the damage and whether the furnace is still worth repairing.
