AfterFast, Reliable Furnace Repair Across Converse
Most furnace repairs in Converse run $150-$700 and are completed in a single visit, with our Furnace Repair team dispatching from our San Antonio office to reach Converse homes the same day you call. When your furnace quits on a January morning or your heat pump blows cold air during a freeze, you need a technician who knows the quirks of Converse’s 1980s-2000s builder-grade housing stock, not a generic checklist. We’re Coldharbour Heating & Air, independently owned and operated since 2003 as part of the Kingswell network, and we’ve been tracking the specific failure patterns in Converse’s attic-closet furnaces and undersized ductwork for years. Call (817) 402-2972 anytime - a live person answers, even at 2 a.m.
Why Coldharbour Heating & Air Is Converse’s Preferred Furnace Repair Company
Converse homeowners have long memories about who shows up and who doesn’t. We’ve built our reputation here by keeping four promises in writing: the price before the first tool comes out, a firm arrival window, a clean job site, and our 365-Day Done Right Promise. If a repair fails within a full year, we come back and fix it at no charge. That guarantee isn’t verbal; it’s on paper before the technician leaves.
Our crews know the terrain. We understand how the 78109 ZIP’s slab-on-grade tract homes route ductwork through unconditioned attics, and how that 20-40-year-old metalwork loses efficiency every summer when temperatures hit 100°F for weeks straight. We know the neighborhoods - Converse Valley, Rolling Meadows, the streets off FM 78 - and we know which subdivisions were built with builder-grade furnaces now hitting their third decade of service.
Speed matters when the heat goes out. Our dispatch coordinates from San Antonio to get trucks to Converse quickly, and because our technicians are trained on nine major brands including Trane, Lennox, Goodman, and Rheem, the first visit usually finishes the job. No waiting for a “specialist” who never arrives.
Victor Mancini leads Coldharbour with the same steady approach that built the Kingswell name: say what you’ll do, do it, and put it in writing. No corporate runaround, no franchise boilerplate.
Heat Pump Repair in Converse
Heat Pump Repair in Converse addresses a system that both heats and cools your home by moving heat rather than generating it - and in our climate, that dual duty means these systems run hard most of the year. When a Converse homeowner’s heat pump switches to defrost mode too often, blows cold air in heating mode, or won’t shift out of cooling, the culprit is usually a failed defrost board, stuck reversing valve, or refrigerant charge issue. Most heat pump repairs in Converse fall in the $150-$700 range, with diagnostics identifying whether the problem is electrical, mechanical, or a sealed-system leak.
Defrost and Reversing Valve Failures
Converse’s humid winters and occasional hard freezes stress heat pump defrost cycles. A stuck reversing valve - the component that switches your system between heating and cooling - leaves you with one or the other, often at the worst possible time. We test valve coil voltage and refrigerant pressures to confirm the failure before quoting replacement.
Refrigerant Charge Problems in Older Systems
Many Converse heat pumps still run on R-22 or have been topped off with substitute blends by prior owners or handymen. These blends can mask underlying leaks and may void any remaining equipment warranty. We document the refrigerant type and charge level so you know exactly what you’re working with, not what the last tenant left behind.
Heating Repair in Converse
Heating Repair in Converse covers furnaces, heat strips, and the full range of components that keep your home warm when temperatures drop. Given Converse’s position in northeastern Bexar County, where February 2021 proved that central Texas freeze events are real and destructive, heating repair here often means addressing systems that were never sized for sustained cold. Most heating repairs in Converse run $150-$700, whether we’re replacing a failed ignitor, a cracked heat exchanger, or a heat strip that couldn’t keep up during a hard freeze.
Heat Exchanger and Combustion Safety
Original furnaces from the 1980s and 1990s in Converse are now well past their designed service life. Cracked or corroded heat exchangers leak combustion gases into your home’s airflow - a genuine safety hazard we check with visual inspection and combustion analysis. We don’t patch these; we document the failure and explain your options clearly.
Heat Strip and Blower Motor Issues
Many Converse homes rely on heat strips as backup or primary heat, especially in all-electric subdivisions. Undersized strips or weak blower motors can’t move enough air across the elements, causing the system to cycle on limit or blow lukewarm air. We measure amp draw and airflow to find the real bottleneck, not just swap the obvious part.
Trusted Brands We Service in Converse
Our technicians carry diagnostic tools and common parts for Trane, Lennox, Goodman, and Rheem systems - the brands we see most often in Converse’s original and replacement installations. Because we train on the full lineup of nine major residential brands, including Carrier, York, and American Standard, the technician who arrives can work on whatever system is already in your home. We don’t believe in sending a “sales specialist” to diagnose what a technician should repair. For Converse customers, that means faster turnaround and fewer return visits.
Common Furnace Repair Problems We See in Converse Homes
- Heat exchanger failures in original 1980s-1990s furnaces. Corroded cells hide behind attic closet panels, and the system limps along with reduced airflow until a carbon monoxide risk or complete failure forces the issue. We document these with photos and combustion test results.
- Failed heat strips and undersized backup heat. Many Converse homes have no emergency heat strategy beyond the original equipment spec, so a February freeze event flips straight to no-heat calls. We evaluate whether your strips match your home’s heat loss calculation.
- Leaky or disconnected attic duct runs causing high static pressure. The original flex duct in Converse’s tract homes has often sagged, torn, or pulled loose at boots. This stresses the blower motor and can make a furnace short-cycle or trip on high limit - a problem a new motor alone won’t fix.
- Substitute refrigerant blends masking low charge on R-22 systems. Prior handymen or landlords top off leaking systems with blends that void warranty and disguise coil damage. We identify these during heating-season calls when the system runs in heat pump mode, before a summer compressor failure leaves you with no cooling at all.
Pricing for Furnace Repair in Converse, TX
We give every Converse homeowner a written price before any work begins. No exceptions, no surprises at the door. Here’s what typical repairs cost in our market:
| Service | Price Range |
|---|---|
| Furnace repair (diagnostic and common part replacement) | $150-$700 |
| Heating repair (heat strip, blower, or limit switch) | $150-$700 |
| Heat pump repair (defrost board, reversing valve, or charge adjustment) | $150-$700 |
| Tune-up (furnace or heat pump safety and performance check) | $80-$200 |
What moves the needle within these ranges? The part itself, whether the failure is accessible in an attic closet or requires additional labor, and whether we find secondary damage from deferred maintenance. A simple ignitor replacement runs toward the lower end. A heat exchanger failure in a 30-year-old furnace usually pushes higher and triggers a replacement conversation. We explain where you land and why, in writing, before you decide. Estimates are free - call (817) 402-2972 to schedule.

FAQs About Furnace Repair in Converse
A furnace limit switch trips when the heat exchanger overheats, usually from restricted airflow or an overfired burner. In Converse’s older homes, the most common cause is a clogged filter combined with sagging attic ductwork that can’t move enough return air - the blower works harder, the heat builds up, and the switch shuts things down for safety. We measure static pressure and temperature rise to find whether it’s a filter, a duct problem, or a failing blower motor. Call (817) 402-2972 and we’ll sort it out - estimates are free.
Yes, heat strip replacement is typically a straightforward repair that doesn’t require a full system changeout, provided the air handler and ductwork are in reasonable condition. We see this call frequently in Converse’s military rental properties near Randolph, where PCS turnover means new tenants inherit equipment with unknown history. We test the strip’s amp draw, sequencers, and airflow before quoting, and we document everything in writing for your property manager. Call (817) 402-2972 to schedule.
Sometimes, but only after we inspect the heat exchanger and evaluate the full system. Original furnaces from that era in Converse are now 35-40 years old, well past design life, and heat exchanger cracks are common. If the exchanger is sound and the repair is minor - a ignitor, a gas valve, a blower capacitor - repair can buy you time. If the exchanger is compromised or the ductwork is severely undersized, we show you the numbers and explain why replacement saves money long-term. We don’t push either direction; we put the facts in writing and let you decide.
Converse’s transient military rental population and frequent property flips create a market for quick, cheap HVAC “fixes” that hide problems rather than solve them. Prior owners or handymen top off leaking R-22 systems with substitute blends like MO99 or R-407C, which can mask coil leaks and void any remaining manufacturer warranty. These blends often work poorly in heat pump mode, causing heating problems that show up in winter. We identify and document the refrigerant type on every call so you know what you’re actually working with.
We prioritize no-heat calls when temperatures drop below freezing, and our San Antonio dispatch coordinates to get trucks to Converse as quickly as road conditions allow. During widespread freeze events, demand spikes across Bexar County, but our live-answer phone coverage means you’re never stuck in a voicemail tree - a real person logs your call and gives you a realistic arrival window. We recommend calling (817) 402-2972 at the first sign of trouble; waiting until nightfall means longer queues and colder houses.
