Furnace Repair in Columbus, TX
High ceilings, original windows, and heating equipment retrofitted into a house built long before central heat existed. That is the Columbus heating challenge in one sentence, and it explains why so many homes here have a furnace that works while the house still feels cold.
Cannell Air Conditioning & Heating serves Colorado County out of El Campo. We are family owned, we started in 1966, and we diagnose the whole system.

Signs Your Furnace Needs Repair
In an older Columbus home, the warning signs are easy to blame on the house.
- The furnace never shuts off during a cold snap
- Upstairs rooms stay cold while the first floor overheats
- A rumble or bang when the burners light
- Registers that blow noticeably weaker than they used to
- Cycling that has grown shorter and more frequent each winter
- Rust or scorching visible on the furnace cabinet
Some of that is the house. A good deal of it is repairable equipment or ductwork.
Furnace Problems We See Most Often
Retrofit heating in historic homes produces a recognizable set of faults.
- Undersized returns causing high limit trips and short cycling
- Leaky duct runs in unconditioned attic and crawl space
- Failed hot surface ignitors after the long idle summer
- Flame sensors coated from dust and infrequent operation
- Flue terminations blocked by leaf debris from heavy oak canopy
- Blower motors worn from carrying an oversized cooling season load
Airflow issues are the thread running through most of them.
Our Furnace Repair Process Explained
We start where safety demands it, with the heat exchanger, the flue, and combustion air, then verify gas pressure and observe a full ignition sequence. In older homes we also measure static pressure, because a furnace short cycling on high limit is almost always being starved of return air.
Once the cause is clear we explain it plainly and give you the price before starting. Our technicians are trained on all makes and models and receive ongoing training.
A Recent Furnace Repair Call in Columbus
Harriet had a furnace in a century old house that ran for six or seven minutes, shut down, and restarted a few minutes later all evening. Nothing in the cabinet had failed. Static pressure showed a return that was far too small for the equipment. We added return air capacity, cleaned the blower, and the short cycling stopped completely.

Frequently Asked Questions
Do you cover Columbus and the surrounding county?
Yes. Colorado County is one of the four counties we serve, along with Wharton, Matagorda, and Jackson. Columbus is a regular part of our route and rural county addresses are included.
Why does my furnace short cycle?
Most often because the high limit is tripping on restricted airflow. Undersized returns, a dirty filter, or closed off registers all cause it. The furnace itself is frequently fine, and correcting airflow solves the problem for good.
Can a historic home be heated evenly?
It can be improved considerably. High ceilings and original windows raise the load, but duct sealing, better return air, and correct equipment sizing address most of the imbalance. We diagnose the distribution, not just the furnace.
Should I be concerned about carbon monoxide with an older furnace?
It is worth taking seriously with any gas appliance. We inspect the heat exchanger and venting on every heating call, and we recommend carbon monoxide detectors on each level of the home with sleeping areas.
Do you handle heating and cooling together?
Yes. We are a full service heating and air conditioning company and a one stop source for heating, cooling, and indoor air quality. The same technicians who service your furnace know your cooling system as well.
