Common Heating & Furnace Repairs We Handle
Most no-heat calls trace back to a handful of culprits, and because we stock the common parts on every truck, most repairs are finished in a single visit:
- Furnace won't ignite or stay lit — failed igniters, flame sensors, or gas-valve issues on gas furnaces.
- System runs but blows cold air — often a heat-pump reversing valve, a tripped limit switch, or a thermostat miswire.
- Short cycling — the furnace turns on and off rapidly, usually from a dirty flame sensor, clogged filter, or overheating limit.
- No power or no response — blown fuses, failed control boards, or a tripped safety switch.
- Loud or unusual noises — worn blower motors, cracked belts, or debris in the system.
- Weak or uneven heat — failing blower motors, duct problems, or an aging system losing capacity.
We service every major brand of gas furnace, electric furnace, and heat-pump heating system — not just the ones we install.

Furnace & Heat Pump Installation in Round Rock
When a heating system is past the point of a smart repair — usually 15+ years old, needing frequent fixes, or driving up your energy bills — we'll lay out honest replacement options with no pressure to spend more than you need. We size every system to your home rather than upselling the biggest unit, walk you through efficiency and cost trade-offs (gas furnace vs. heat pump, single-stage vs. variable-speed), and give you a clear, upfront quote. As a Carrier Factory-Authorized team (and a Lennox dealer), we install high-efficiency systems backed by strong manufacturer warranties — and we stand behind every install with our own 100% satisfaction guarantee. You can see installed prices for gas-furnace and heat pump systems on our system replacement cost page before anyone visits.
Heating Maintenance & Tune-Ups
Round Rock furnaces sit idle for most of the year, so the first hard freeze is when problems surface — usually at the worst possible time. A fall tune-up catches worn igniters, dirty flame sensors, and safety issues before they leave you without heat, keeps your energy bills down, and protects your manufacturer warranty (most require documented annual service). Our maintenance visit covers a full safety inspection, a 15-minute carbon monoxide test, and checks of the flame sensor, ignitor, safety switches and airflow so your system is ready before the cold arrives. Koala Club members get a Heat Check at the start of every heating season — see what the Koala Club includes.

Frequently Asked Questions
Do you repair all furnace brands, or only the ones you sell?
We service every major brand of gas furnace, electric furnace, and heat-pump heating system — not just the ones we install. Our techs are Carrier Factory-Authorized and trained across all major manufacturers.
My heat pump is blowing cold air — is that an emergency?
Not always, but it's worth a same-day look. It's often a reversing-valve issue, a thermostat setting, or a system stuck in defrost — some are quick fixes, others need a tech. Call (512) 759-8800 and we'll help you figure out how urgent it is.
Should I repair or replace my furnace?
As a rule of thumb, if your system is under about 15 years old and the repair costs less than a third of a replacement, repair usually makes sense. Older systems with frequent failures or rising energy bills are better candidates for replacement — and we'll give you an honest recommendation either way, with no pressure.
How fast can you come out?
Same-day service is available whenever we can, especially for no-heat calls during a cold snap. Call (512) 759-8800 and we'll get you the soonest available window.
How much does furnace repair cost in Round Rock?
Most common furnace repairs run $109 to $277 at our standard published prices, or $98 to $249 for Koala Club members, plus the $131 service fee ($49 for Club members, waived when you have paid work done). Your tech shows you the exact price from our pricing book before any work starts.
Do you install new furnaces and heat pumps?
Yes. We're a Carrier Factory-Authorized Dealer and a Lennox dealer and install gas furnaces, heat pumps and complete heating and cooling systems. Replacement estimates are free.
What's included in a Heat Check?
A Heat Check is our pre-season furnace and heat pump maintenance visit: a full safety inspection, a 15-minute carbon monoxide test, and checks of the flame sensor, ignitor, safety switches and airflow so your system is ready before the first freeze. It's included in every Koala Club membership, and non-members can book one too.
