In San Antonio, winter rarely sticks around for long—but when a cold front rolls in, it can drop temperatures fast. As we move closer to spring, most homeowners start thinking about A/C tune-ups and preparing for the first real stretch of heat. That’s exactly why late-season heating problems are easy to ignore: the heater “mostly worked,” and you assume you’ll deal with it next year.

But putting off heating repairs can backfire. Small issues often get worse while the system sits unused—then next winter you’re stuck with no heat, higher repair costs, or an emergency call during the busiest season.

At Cowboys Air Conditioning & Heating, we provide furnace and heating repair in San Antonio with 24/7 emergency service, and we work on gas and electric systems, plus heat pumps. If you’ve noticed any of the issues below, call (210) 495-7771 now—before the problem turns into next season’s surprise.

We serve San Antonio and nearby communities throughout the metro area, including places like Boerne, Helotes, Converse, Schertz, Cibolo, Universal City, Live Oak, and New Braunfels.

1) Faulty thermostat issues

A thermostat is the “command center” for your heating system. If it’s not reading temperatures correctly—or it can’t communicate properly with your equipment—you’ll see problems that look like major heater failure, even when the heater itself is fine.

Common signs your thermostat needs repair or replacement

• The heater won’t turn on when it should

• The system runs continuously and won’t shut off

• The display is blank, unresponsive, or frequently resets

• Temperatures feel inconsistent from one cycle to the next

Thermostat malfunctions can cause nonstop operation (which wastes energy and accelerates wear) or short cycling (which reduces comfort and stresses components).

Why you should fix it now

Even if you won’t rely on heat much over the next few weeks, a thermostat problem can still matter because:

• It may also affect cooling performance if the thermostat controls both heating and A/C

• It can hide bigger issues (wiring, safety switches, control board problems)

• It’s easy to forget about until the first cold night next year

Cowboys AC can troubleshoot thermostat communication issues and recommend the right fix—whether it’s calibration, wiring repair, or upgrading to a modern programmable/smart thermostat.

2) Uneven heating and cold spots around the house

If some rooms were warm this winter while others stayed cold, don’t assume it’s “just how the house is.” Uneven heating is often a sign your system is working harder than it should—and it can point to issues that will also affect summer cooling.

What uneven heating usually means

Uneven temperatures can be caused by:

• Duct leaks or disconnected ducts (conditioned air never reaches certain rooms)

• Dirty filter / restricted airflow

• Blower or burner issues inside the heating system

• Thermostat placement problems (thermostat reads one area, not the whole house)

Cowboys AC specifically lists uneven heating or cold spots as a common sign your system may need repair.

Why late-season is the perfect time to address it

When it’s not freezing outside, diagnostics and repairs are often easier to schedule—and you’re not risking comfort while repairs are being completed. Plus, fixing airflow problems now can improve A/C performance when San Antonio heats up again.

3) Furnace runs constantly (or seems to “never stop”)

If your furnace ran nonstop this winter, that’s not something to ignore—especially if your home still didn’t feel comfortable. A heating system that can’t cycle normally is often fighting one or more hidden problems.

Common reasons a furnace runs all the time

• Thermostat issues or incorrect settings

• Dirty filters and restricted airflow

• Failing components (sensors, limit switches, blower problems)

• Duct leakage (the home never reaches set temperature efficiently)

Continuous runtime is a known symptom tied to thermostat or system problems and can drive up energy bills and wear out parts faster.

Why it matters even if “winter is basically over”

A furnace that ran constantly likely:

• Wasted energy and added strain all season

• Needs a proper inspection to prevent bigger failures

• May have airflow issues that will also hurt A/C efficiency in spring/summer

Cowboys Air Conditioning & Heating offers heating maintenance and seasonal tune-ups designed to keep systems running safely and efficiently through San Antonio’s fast-changing winter weather.

Bonus: Don’t skip maintenance just because the season is ending

The end of heating season is a great time to schedule maintenance because you’re catching problems before they compound. Cowboys AC offers an HVAC maintenance program designed to help prevent breakdowns, reduce surprise repairs, and support lower long-term operating costs.

Even a simple inspection can uncover issues like:

• Worn igniters or flame sensors

• Airflow restrictions and dirty filters

• Safety switch problems

• Duct leaks that reduce comfort and efficiency
