Furnace and Heating Repair in Keller, TX

Most Keller homes heat with gas. According to the Census, 63 percent of them use utility gas and 36 percent use electricity, so when a cold front comes through and the heat quits, the problem is usually a gas furnace that sat idle for months. Our technicians offer same-day heating repair and 24/7 dispatch for no-heat emergencies, give you an upfront price before any work starts, and include a safety check on every heating repair. Call us at 817-290-3373 or book online.

The Gas Furnace in a Keller Home

With more than half of Keller built between 1990 and 2009, and a median house that dates to 1999, a lot of Keller furnaces are original to the house or on their first replacement. A gas furnace brings its own set of problems on top of the ones any heating system has, and one real risk: a cracked heat exchanger or bad venting can leak carbon monoxide, which you cannot see or smell. Furnace calls in Keller come to the same team that handles Keller HVAC, plumbing & electrical work all year. Who lives in the house sharpens the picture. Among Keller homeowners, 70 percent heat with gas, while 72 percent of renter households heat with electricity, so an owner’s no-heat call is usually about a burner and a flue, and a tenant’s is more often a heat pump or an electric furnace.

That is why every heating repair we do includes a safety check. If your carbon monoxide alarm sounds, you feel dizzy or nauseated, or you smell gas, leave the house, do not flip any switches, and call 911 and your gas utility from outside. Then call us.

The First Cold Night of the Year

A hot, dusty smell in the first minutes of the first cold night is usually dust burning off the heat exchanger and burners after months of sitting, and it fades. A smell that lingers, gets stronger or comes with smoke is a different call. On a heating visit we check the ordinary items that fail after a long idle stretch: the filter, the blower, the ignition, the controls and the safeties. Outside Keller, we bring the same furnace and heating repair to homes across Fort Worth.

Keller’s hard nights are few but real. At the NOAA station at Fort Worth Alliance Airport, about 7 miles from the city, the low reached 22 degrees or colder on 4 to 12 nights each winter from 2020-21 through 2025-26, and 2 below zero on February 16, 2021.

Heating Problems We Fix in Keller

  • No heat, or a furnace that will not turn on
  • Weak airflow, or cold air from the vents
  • Short cycling, where the furnace turns on and off repeatedly
  • Ignitor, flame sensor or pilot problems
  • Blower motor failures and strange noises
  • Thermostat problems and uneven heating

Our trucks carry the common parts, so most heating repairs are done in one visit. For the 36 percent of Keller homes that heat with electricity, we work on every type of heating system, heat pumps included.

What Keller's Code Says About Heat and Gas

Keller adopts the 2021 residential and fuel gas codes with its own amendments. A few of them matter on a heating call:

A 22 degree winter design temperature

Keller’s climate table sets the winter design temperature at 22 degrees Fahrenheit. That is the outdoor temperature a heating system is sized to keep up with, so a furnace that falls behind on a night in the low 20s may be at the edge of what it was sized for, while one that falls behind at 40 degrees has a problem.

No unvented heater as the only heat

One or more unvented room heaters may not be the sole source of comfort heat in a Keller home. Existing approved units may stay in use unless the code official finds them unsafe.

Gas piping rules

Underground gas piping must be buried at least 18 inches, medium-pressure gas piping must be tagged at both ends with its operating pressure, and shutoff valves on flexible stainless steel (CSST) gas piping must be supported within 12 inches of the valve.

Pressure testing

New gas piping is pressure tested before it goes into service, at no less than 3 psi unless the code official allows the lower mercury test, using a calibrated gauge.

Keller Problems We Solve, and How

A kitchen hood that pulls against the furnace. Keller amends the makeup air rule: where a gas appliance that is neither direct-vent nor mechanically vented sits inside the house, a kitchen exhaust over 400 cubic feet per minute needs makeup air. If you have added a large range hood since the house was built, mention it when you book a heating call.

A system that sat all summer. The first cold night is a poor time to find out the furnace has a problem. Gold Star Membership includes an annual tune-up and safety inspection, priority scheduling and 15 percent off repairs, so the check happens before the first cold snap instead of during it.

An older furnace near the end. When the problem is a blower motor or a heat exchanger rather than an ignitor or a thermostat, the repair costs more, and on an older furnace replacement may be the better value. We give you a flat price for the repair and tell you honestly when replacement makes more sense.

The Rest of the System in a Keller House

The furnace blower also pushes the cooled air in summer, so a weak one found on a heating call matters for Keller AC repair too. A gas water heater shares the furnace’s gas service, and the plumbers who handle water heaters in Keller work on those lines. An electric furnace that keeps tripping its breaker goes to the electricians who work in Keller.

Frequently Asked Questions

Keller’s code sizes heating to a 22 degree winter design temperature, and the Alliance Airport station near Keller has reached that or colder on 4 to 12 nights every winter since 2020-21. On those nights even a healthy furnace can run nonstop and fall a little behind.

Every heating repair we do includes one, because a cracked heat exchanger or bad venting can leak carbon monoxide you cannot see or smell. If the CO alarm sounds, leave the house and call 911 from outside.

Yes. The Census counts 72 percent of Keller renter households on electric heat, and we work on every type of heating system, heat pumps and electric furnaces included. If the owner or manager approves repairs, they get the price before work starts.

It can. Keller’s amended makeup air rule applies where a gas appliance that is neither direct-vent nor mechanically vented sits inside the house: a kitchen exhaust over 400 cubic feet per minute then needs makeup air. Mention a large range hood when you book.

The ordinary items that sit idle for months: the filter, the blower, the ignition, the controls and the safeties. We check each of them on a heating visit and give you a flat price before any repair begins.
