When your furnace won't start, blows cold air or keeps shutting off, Otis Heating & Air Conditioning will find the problem and get your heat back on.

We are a family-owned heating and cooling company based in Crosby, Texas, and we service all makes and models of furnaces, gas and electric. Our technicians test the whole system, from the thermostat to the burners and blower, so the repair fixes the cause and not just the symptom. Winters here are short, but the cold snaps that roll through Harris County can drop overnight temperatures fast, and that is when a furnace that sat idle all summer tends to fail.

Signs Your Furnace Needs Repair

Call for furnace repair when you notice any of these:

No heat at all The thermostat calls for heat, but the furnace never starts, or the blower runs with nothing warm coming out.

Cold air from the vents A furnace that blows cool air usually has an ignition, gas supply or overheating problem that shuts the burners off.

Short cycling The burners light, run for a few minutes and shut down again before the house warms up.

Noises and smells Banging, squealing or rattling, or a burning smell that lasts well past the first run of the season.

A yellow, flickering flame Gas burners should burn mostly blue. A lazy yellow flame points to a dirty burner or a combustion problem that needs a closer look.

Climbing utility bills A furnace that works harder than it should costs more to run, even when the weather hasn't changed.

Common Furnace Repairs We Handle

Most no-heat problems come down to a handful of parts:

Ignition and pilot problems Furnaces in the Houston area sit idle most of the year. Pilot lights go out, igniters wear out and gas valves can stick after a long cooling season.

Thermostats and controls A thermostat that has lost calibration or a control board that stops sending the call for heat can look like a dead furnace.

Blower and airflow Clogged filters, worn blower motors and blocked returns make a furnace overheat, which trips its safety switch and shuts the burners down.

Electric heat and backup heat strips Many homes here heat with an electric furnace or with heat pumps that switch to backup heat strips on cold nights. Burned-out elements and failed relays leave the house cold and the power bill high.

Heat exchanger concerns A cracked heat exchanger can let combustion gases mix with the air you breathe. A gas furnace that smells odd or keeps shutting itself down should be checked, not restarted over and over.

Why Furnaces Fail in Crosby Winters

Heating seasons in Southeast Texas are short. A furnace may run a few dozen nights a year, then sit through eight months of air conditioning weather in a hot attic, closet or garage. Dust settles on the burners and flame sensor, pilot lights go out, and parts that haven't moved since February are asked to work on the first cold night of November or December.

That is why the first cold front of the season is when so many furnaces quit, and why the February 2021 freeze showed how quickly a house loses heat once the system stops. A furnace tune-up in the fall catches most of these problems before you need the heat.

How a Furnace Repair Visit Works

Diagnosis The technician checks the thermostat, power, gas supply, ignition, flame, blower, filter and safety switches to find what failed.

A clear explanation You hear what is wrong, what the fix involves and whether any other part is close to failing, so you can decide what to do.

The repair We replace or repair the failed part and fix the cause, such as a clogged filter or blocked return, so it doesn't happen again next week.

A full test We run the furnace through a complete heating cycle to confirm it lights, heats the house and shuts off the way it should.

What to Check Before You Call

A few quick checks can save you a service visit:

Thermostat Make sure it is set to Heat, set above the room temperature, and has fresh batteries if it uses them.

Air filter A filter packed with dust can make the furnace overheat and shut off. Replace it if you can't see light through it.

Power Check the breaker and the furnace's power switch, which usually looks like a light switch on or near the unit.

Gas If you smell gas, don't run the furnace or flip switches. Leave the house and call your gas company from outside.

If those all check out and the heat still won't come on, call us at (281) 328-3255.

Repair or Replace Your Furnace?

Most furnace problems are a single failed part, and repairing it is the right call. Replacement is worth talking through when the furnace is older than about 15 years, when the heat exchanger is cracked, or when repairs keep stacking up winter after winter. A common rule of thumb: if a repair would cost more than half the price of a new furnace, replacing it usually makes more sense.

We will give you a straight answer either way. When a new system is the better spend, we handle furnace installation with Armstrong Air equipment sized for your home, and you can spread the cost with financing through Goodleap.

Frequently Asked Questions About Furnace Repair

The usual causes are a clogged air filter, closed or blocked vents, leaky ductwork, a thermostat that needs calibration, or a furnace that is worn or sized wrong for the house. Start by replacing the filter and opening every vent. If the house still falls short of the setting, we inspect the furnace, airflow, and ducts to find the cause.

Check the thermostat first: it should be set to HEAT, a few degrees above room temperature, with fresh batteries. Then check the circuit breaker and the furnace power switch, and make sure the air filter isn't clogged. If the furnace still won't start, call (281) 328-3255 instead of attempting repairs on gas or electrical parts.

Banging, squealing, rattling, or grinding sounds point to different problems, from delayed ignition and loose panels to a worn blower motor. Strange noises are one of the common signs that a furnace needs attention, so have it checked before a small repair turns into a breakdown. Regular maintenance catches most of these issues early.

A dusty, burning smell for the first few minutes of the heating season is normal: dust on the burners and heat exchanger is burning off. A smell that lingers, a burning-plastic or electrical odor, or any smell of gas is not normal. If you smell gas, leave the house and call your gas utility from outside, then call us.

The heat exchanger keeps combustion gases, including carbon monoxide, separate from the air your furnace blows into your home. A crack can let those gases mix with your indoor air, so a cracked heat exchanger is a safety problem, not just a repair. That is why our fall heating service includes a heat exchanger inspection and carbon monoxide safety testing.

If a repair would cost more than 50% of what a replacement costs, replacing the furnace is often the more cost-effective choice, especially when the system is 10 to 15 years old with frequent repairs and rising energy bills. We lay out both options so you can decide, and we offer flexible financing through Goodleap.
