Preparing Your Heater for Winter in Texas
Texas winters are short but unpredictable. When the temperature drops 40 degrees overnight, you want a heater that has already been checked.

Heating season in The Woodlands is short compared to states further north. That is part of the problem. A furnace or heat pump that sits idle from March through November can develop issues you will not discover until the first real cold front arrives. A cracked heat exchanger, a failed ignitor, or a seized blower motor will not announce itself until you need the system and it does not respond.
Why Fall Maintenance Matters Here
In The Woodlands, Spring, Conroe, and Magnolia, the shift from cooling to heating can happen in a single day. One afternoon it is 85 degrees. By midnight it is 38. That rapid swing means your system has to switch modes with no warm-up period. A dirty flame sensor, a clogged filter, or a worn-out capacitor will pick that exact moment to fail.
Fall maintenance is about catching those failures before they leave you without heat. The best time to schedule it is October or early November, before the first cold front and before every HVAC company in the area is booked solid with emergency calls.
What a Heating Tune-Up Covers
A proper heating maintenance visit is not a quick filter swap. It includes a set of checks that directly affect safety and reliability:
- Inspect the heat exchanger for cracks or corrosion (a cracked exchanger can leak carbon monoxide)
- Test the ignitor and flame sensor, clean or replace as needed
- Check thermostat calibration and verify the system responds correctly to mode changes
- Inspect the flue and venting for blockages or separation
- Measure amp draw on the blower motor to catch early bearing wear
- Replace the air filter if it is restricted
Heat Pumps vs. Gas Furnaces in This Climate
The Woodlands sits in a climate zone where both gas furnaces and heat pumps work well. A heat pump is efficient down to about 35 to 40 degrees, which covers most Texas winter days. Below that threshold, heat pump output drops and the system relies on auxiliary electric heat strips, which use significantly more electricity.
A gas furnace produces warmer air at the registers and does not lose efficiency in extreme cold. The tradeoff is that it requires a gas line and annual combustion safety checks. Both are valid choices, and the right answer depends on your home, your ductwork, and whether you have natural gas service. The Woodlands Plumbing & Air installs both gas and electric systems and can walk you through the tradeoffs for your specific situation.
Lessons from the Texas Freeze
The February 2021 winter storm taught Texas homeowners that "it doesn't get that cold here" is not a plan. Pipes burst, systems that had never been tested in sustained freezing conditions failed, and homes that had no backup heat source lost it entirely. Even if your heater runs fine most winters, a maintenance check that includes the heat exchanger and gas valve gives you confidence that the system will hold up when it actually matters.
Insulating exposed pipes, sealing gaps around ductwork in the attic, and confirming that your thermostat's emergency heat mode actually works are small steps that pay off during a real freeze event.
Carbon Monoxide: The Risk You Cannot See
A cracked heat exchanger is the most dangerous furnace defect because it is invisible. Carbon monoxide is odorless and colorless. If your home does not have CO detectors on every level, install them before heating season starts. If your detectors are more than five years old, replace them. This is not a substitute for a professional inspection, but it is a safety net that costs under $30 per detector.
