Furnace and heating repair
Furnace repair in Buda, TX
Furnace repair means finding out why your heat stopped working, fixing the part that failed and checking that the system runs safely before we leave. Cool Kings Heating & Air handles furnace repair and heating repair for homes in Buda, TX, Kyle, South Austin and the surrounding Hays and Travis County area. We work on gas furnaces, heat pumps and the electric heat strips inside air handlers, and same-day appointments are available across our service area.
Heating in Central Texas comes in short bursts. A furnace can sit idle from spring until late fall, then get asked to run all night when the first hard cold front blows through. That long rest is why so many no-heat calls come in the first cold week of the season: an igniter that cracked, a flame sensor that coated over, or a draft inducer motor that stuck after months of sitting still.
Corey and Terry Lutrick started Cool Kings in Buda in 2015, and the same father-and-son standards apply whether we are working on a 20-year-old furnace in an older ranch house or a heat pump in one of the newer subdivisions around Kyle, TX. We tell you what failed, why it failed and what it costs to fix before any work starts.
Common furnace problems in winter
The most common furnace problems we see are ignition failures, dirty flame sensors and airflow trouble from clogged filters. Most of them show up as one of three complaints: no heat at all, a furnace that starts and then shuts off, or vents that blow cool air.
Igniter and pilot problems
Most gas furnaces in Buda and Kyle homes use a hot surface igniter, a small ceramic part that glows hot enough to light the gas. Igniters get brittle with age and crack, and a cracked igniter means the burners never light. You hear the inducer motor start, then nothing happens, and after a few tries the furnace locks itself out. Older furnaces with a standing pilot have their own version of this problem, usually a weak thermocouple. Both are quick repairs once the cause is confirmed.
Dirty flame sensor
If the burners light for a few seconds and then shut off, the flame sensor is a likely suspect. The sensor is a thin metal rod that proves to the control board that a flame is present. A light coat of buildup is enough to make the board think the flame went out, so it shuts the gas off as a safety step. Cleaning or replacing the sensor usually solves it, but a sensor that keeps fouling can point to a burner or venting problem that needs a closer look.
Blower motor and airflow
The blower pushes heated air through your ducts. A failing blower motor or capacitor can leave the furnace hot and the house cold, and you may hear humming or smell something hot near the unit. A badly clogged filter causes damage of its own: the heat exchanger runs too hot, the high limit switch trips and the furnace starts short cycling. Change a dirty filter first. If the problem stays, it is time for service.
Thermostat and control problems
Some no-heat calls turn out to be the thermostat, not the furnace. Dead batteries, a setting left on cool or a loose wire can all look like a broken heater. When the thermostat itself has failed, our thermostat repair and installation service can replace it with a standard or smart model. Inside the furnace, a failed control board or transformer can shut everything down at once, and those parts need a real diagnosis before anyone orders them.
Heat pump repair
Many Central Texas homes heat with a heat pump instead of a gas furnace. A heat pump is an air conditioner that can run in reverse, pulling heat out of the outdoor air and moving it inside. Heat pump repair looks different from furnace repair because the outdoor unit does the heating work all winter, not just the cooling work all summer. Much of that outdoor work, from fan motors and capacitors to refrigerant leaks, overlaps with AC repair, so the same technicians handle it year round.
Defrost problems and ice on the outdoor unit
On cold, damp mornings, frost builds up on the outdoor coil. A working heat pump clears it with a defrost cycle: it switches to cooling mode for a few minutes to warm the coil, and you may see steam rising off the unit. That is normal. An outdoor unit caked in solid ice, or one that never seems to defrost, has a problem with the defrost control, a sensor, the reversing valve or the refrigerant charge.
Auxiliary heat and emergency heat
Most heat pumps have electric heat strips in the indoor air handler. Auxiliary heat comes on by itself during defrost or when the heat pump cannot keep up, and it costs more to run. Emergency heat is a thermostat setting that shuts the heat pump off and runs only the strips. If your thermostat shows aux heat running for hours on a mild day, or the house only stays warm on emergency heat, the heat pump needs repair. Leaving it on emergency heat as a workaround will show up on your electric bill.
Cold snaps and freeze readiness
Winter Storm Uri in February 2021 showed Central Texas how quickly a house loses heat in a hard freeze. A cold snap is the worst time to learn that a heat strip has burned out or an outdoor fan motor is failing, because every heating company in the area is answering the same calls at once. If your heat pump struggled last winter, have it checked before the next freeze instead of during it.
Carbon monoxide and furnace safety
A gas furnace burns fuel, so a cracked heat exchanger, a blocked flue or a failed draft inducer can let carbon monoxide into your home. Carbon monoxide has no color and no smell. The CDC lists headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion as the most common symptoms, and reports that more than 400 Americans die each year from unintentional CO poisoning not linked to fires (CDC).
The CDC recommends having your heating system serviced by a qualified technician every year. The U.S. Consumer Product Safety Commission recommends CO alarms with battery backup on every level of the home and outside sleeping areas (CPSC). If a CO alarm sounds, or several people in the house feel sick at the same time, get everyone outside and call 911 from there. Leave the furnace off until it has been inspected.
What you can safely check yourself
- Make sure the thermostat is set to heat and the setpoint is above the room temperature.
- Check the breaker for the furnace or air handler and the service switch near the unit.
- Replace a dirty air filter.
- Make sure supply vents and the return grille are open and clear.
- On a heat pump, clear leaves and debris away from the outdoor unit.
Stop there. Do not open sealed gas components, keep relighting a furnace that locks out, or keep resetting a breaker that trips. Those are jobs for a licensed technician.
Repair or replace your furnace
Repair makes sense for most igniter, flame sensor, motor and control problems, even on an older system. Replacement starts to make sense when the system is old and the repair is large. ENERGY STAR suggests considering replacement when a furnace is more than 15 years old or a heat pump is more than 10 years old, especially if it needs frequent repairs and your energy bills keep climbing (ENERGY STAR).
The most expensive furnace repair is usually a cracked heat exchanger, and on a furnace near the end of its life that repair rarely pays off. When replacement is the better call, we will say so plainly and show you why. Cool Kings is a York factory authorized dealer, and our HVAC installation services cover furnace installation and heat pump installation sized to the home, with financing available.
What furnace repair costs
Furnace repair cost depends on the part, the type of system and how easy the unit is to reach. Cleaning a flame sensor or replacing an igniter costs far less than a blower motor, an inducer motor or a control board, and a furnace tucked into a tight attic takes longer to work on than one in a hall closet. We diagnose the problem first and give you the price before any repair starts, so you decide with the numbers in front of you.
Furnace maintenance before the first cold front
Many first-cold-night breakdowns can be caught early. A good fall furnace maintenance visit cleans the flame sensor, checks the igniter, tests the safety controls and looks over the venting, so small problems get fixed on a mild afternoon instead of a freezing night. Our HVAC maintenance visits cover gas furnaces and heat pumps, including a check of defrost and auxiliary heat on heat pump systems.
