Furnace Repair in Palacios, TX
Flue pipes and vent terminations on the bay take the same salt air that eats condenser coils, and unlike the coil, nobody looks at them until the heat quits. In Palacios that is the most overlooked part of the heating system.
Cannell Air Conditioning & Heating has worked in Matagorda County since 1966. On coastal furnace calls we inspect the venting first, because that is where the problem usually starts.

Signs Your Furnace Needs Repair
On the bay, heating trouble often traces back to something outside the house.
- The furnace lights and then shuts down within a minute
- Repeated lockouts on cold, damp mornings
- Visible rust or scaling on the flue pipe where it exits
- A whistling or rushing sound at the vent termination
- The inducer runs but ignition never happens
- Uneven or lazy burner flame
Any of these deserves a venting inspection before parts get replaced.
Furnace Problems We See Most Often
Salt exposure reshapes the usual list of furnace failures.
- Corroded flue and vent piping causing draft and pressure switch faults
- Oxidized flame sensors that cannot maintain a reliable signal
- Rust in the burner compartment producing an uneven flame
- Corroded electrical terminals causing intermittent operation
- Seized inducer motors after long humid idle periods
- Blocked or corroded combustion air intakes
Catching corrosion early is what keeps a repair from becoming a replacement conversation.
Our Furnace Repair Process Explained
Every Palacios heating call begins outside as well as in. We check the vent termination, the flue run, and the combustion air intake for corrosion and blockage, then move indoors for the heat exchanger inspection, gas pressure verification, and the full ignition sequence.
Components are tested under real operating conditions before anything is quoted. Our technicians are NATE certified and trained on all makes and models, so the diagnosis does not depend on the brand on the cabinet.
A Recent Furnace Repair Call in Palacios
Roberta had a furnace that locked out most cold mornings and ran fine by midday. The ignitor and sensor both tested good. Corrosion at a flue joint was letting the draft weaken on damp mornings, which kept the pressure switch from holding. We replaced the corroded section of vent pipe, resealed the run, and verified draft across several cycles.

Frequently Asked Questions
Why should the flue be inspected on a coastal furnace?
Because salt air corrodes vent piping and terminations from the outside in. A corroded flue weakens draft, which trips safety switches and can allow combustion gases where they do not belong. It is the most common coastal heating fault we find.
My furnace fails on damp mornings and works later in the day. Why?
Humidity and temperature both affect draft. A vent run that is marginal from corrosion or a partial blockage will draw acceptably in dry midday air and fail in the damp cold of early morning. The pattern itself is a clue for diagnosis.
How often should a furnace be inspected here?
Once a year before heating season. Run hours are low on the coast, but corrosion happens whether the unit runs or not, so the annual inspection matters as much here as it does in a colder climate.
Do you charge for the estimate?
Estimates are free and are performed by the owner or a technician instead of a commissioned salesperson. There is a diagnostic charge for a service call, and service agreement members pay a reduced rate.
Can you handle both heating and cooling for my home?
Yes. We are a full service heating and air conditioning company and a one stop source for heating, cooling, and indoor air quality needs. One company knowing your whole system saves time on every call.
