AfterFast, Reliable Furnace Repair Across Universal City
Most furnace repairs in Universal City run $150-$700 and our technicians typically arrive within hours, not days. We dispatch from our San Antonio office and carry parts for Goodman, Rheem, and other common brands so your heat comes back fast.
We’re Coldharbour Heating & Air, and we’ve spent years working in the ranch homes around Joint Base San Antonio-Randolph. The 1960s-1980s slab-on-grade houses that dominate Universal City have a personality all their own: original ductwork baking in unconditioned attics, systems patched between military tenants, and furnaces that have been fighting undersized returns since before load calculations were standard practice. When your blower quits at midnight or your heat exchanger cracks mid-winter, you need someone who knows these houses, not a dispatcher reading from a script. Call us at (817) 402-2972. A live person answers, 24 hours a day.
Why Coldharbour Heating & Air Is Universal City’s Preferred Furnace Repair Company
We don’t ask homeowners to take our word for anything. Every repair comes with a written price before we touch a tool, a firm arrival window, and our 365-Day Done Right Promise on paper. If the repair fails inside a year, we come back and fix it at no charge. That’s The Kingswell Way, and it’s how we’ve operated since 2003.
Our technicians are background-checked, uniformed, and trained on nine major residential brands. They know Universal City’s housing stock: the ranch homes off Kitty Hawk Road, the streets near Randolph High School, the properties along Pat Booker Road. They’ve pulled into attics here and found flex duct separated at the trunk for years, quietly dumping heated air while the homeowner thought the furnace was just “weak.” That local knowledge saves time and money.
Phones are answered by a live person around the clock. No voicemail trees. No “call back in the morning” when your furnace dies on a Saturday night.
Heating Repair in Universal City
Heating Repair in Universal City means working on systems that have been through decades of patchwork fixes, military turnover, and south-central Texas temperature swings. Our calls here range from failed ignitors on 30-year-old Goodman furnaces to blower motors burned out from high static pressure caused by collapsed attic ductwork. Most heating repairs in Universal City fall between $150-$700, with simpler fixes like flame sensor cleaning or capacitor replacement at the lower end and heat exchanger work or blower motor replacement toward the top.
When to Call for Heating Repair
Short cycling, loud banging on startup, or a furnace that runs but never warms the house past 65 degrees are all signs something is wrong. In Universal City’s older ranch homes, we also watch for rooms that never get warm while others roast, which often points to separated flex duct in the attic rather than a furnace problem.
What We Check First
We measure static pressure and inspect duct integrity before quoting any repair. An oversized furnace fighting leaky, attic-routed ductwork will fail again if we only swap the part that broke. This step alone has saved Universal City homeowners from repeat calls on the same system.
Boiler Repair in Universal City
Boiler Repair in Universal City is less common than furnace work, but it matters where natural gas lines don’t reach. Rural properties and outbuildings around the city often run on propane boilers or hybrid heat-pump systems, and those setups break differently than standard gas furnaces. Most boiler repairs in Universal City run $150-$700, same as furnace work, though propane valve issues and circulation pump failures can push toward the higher end if parts need to be ordered.
Propane and Rural Systems
Properties with no natural gas access need technicians who understand propane pressure regulation, venting requirements, and the way exposed outdoor lines behave in a hard freeze. We’ve serviced boilers in workshops and outbuildings where the lines were never winterized, leaving heating-side components damaged months later.
Heat-Pump Backup Failures
Many Universal City homes use heat pumps with electric backup coils. When the heat pump side fails, those coils carry the full heating load and draw massive amperage. We check both stages, not just the symptom, because running on backup heat alone will spike your electric bill and stress the electrical panel.
Trusted Brands We Service in Universal City
Our technicians train on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Goodman and Rheem systems locally because those brands appear so often in Universal City’s Randolph-era housing stock. When a capacitor or gas valve fails, we don’t want you waiting days for a warehouse shipment. For Daikin and York systems, we maintain supplier relationships that get us next-day parts when same-day stock isn’t available. Every repair still gets the written price, the written guarantee, and the same 365-day coverage.
Common Furnace Repair Problems We See in Universal City Homes
- Heat exchanger cracking in long-cycle furnaces. When attic flex duct is undersized or disconnected, the furnace runs longer to hit thermostat setpoint. That extended cycling stresses the heat exchanger, and we’ve found cracks at burner inlets on systems that were “working fine” last season.
- Blower motor burnout from high static pressure. A collapsed return duct or a filter that was upgraded to a restrictive pleated style without checking airflow can push amp draw past spec. We measure before and after any motor replacement.
- Failed ignitors and flame sensors on heat pumps never winterized. The February 2021 freeze damaged outdoor units across this area. Heating-side components failed months later, sometimes not until the next cold snap, when cracked boards and corroded sensors finally quit.
- Separated flex duct dumping heated air into the attic. This is the silent killer in Universal City. Homeowners blame the furnace, but the real problem is a 10-foot gap at the trunk line that has been there since a landlord’s quick patch job three tenants ago.

FAQs About Furnace Repair in Universal City
The limit switch shuts down your furnace when internal temperature gets dangerously high, and in Universal City homes the culprit is almost always restricted airflow. Check your filter first, but also consider that your attic ductwork may have separated or collapsed, a problem we find constantly in the Randolph-era ranch stock where landlords patched between tenants instead of sealing properly. We measure static pressure to confirm before replacing any parts. Call (817) 402-2972 for a free diagnosis.
Yes. Propane systems require different gas valve pressure settings, specialized venting, and technicians who understand how outdoor tanks behave in freeze conditions. Heat-pump hybrids need both refrigeration and electrical expertise. Our technicians are trained for all three, and we carry parts for propane conversions and heat-pump backup coils.
That freeze cracked outdoor coils, damaged refrigerant lines, and corroded electrical components on systems that were never winterized. Some failures showed immediately, but many heat pumps developed heating-side problems months later when corroded boards or weakened capacitors finally quit under winter load. We’re still finding damage in 2025 during routine service calls.
Absolutely. Rural properties around Universal City often have detached workshops, barns, or guest quarters with propane or electric heat. We size equipment for exposed buildings with no wind shelter, run proper venting, and make sure combustion air supply meets code. The same written price and 365-day guarantee applies.
We inspect the full system, measure static pressure, check duct integrity, and give you a written price before any work begins. The price includes parts, labor, and our 365-Day Done Right Promise. If we repair it and it fails within a year, we return at no charge. No trip fees, no diagnostic fees hidden in the fine print. Call (817) 402-2972 to schedule.
