Fast, Reliable AC Repair Across Converse
AC repair in Converse typically runs $150-$650 and most calls are completed same day. When your system quits in July, waiting isn’t an option. Call Coldharbour Heating & Air at (817) 402-2972 and a live person will pick up, 24 hours a day.
We’ve been dispatching crews to Converse from our San Antonio office long enough to know the local housing stock inside out. The 1980s-2000s tract homes off FM 78, the military rentals cycling through near JBSA-Randolph, the original slab-on-grade builds in the 78109 zip - our technicians have worked on all of them. That matters because a compressor that fails in a Converse attic in August is a different job than the same failure in a shaded two-story. We know where the ductwork runs, which panels are original 100-amp service, and why a “simple” refrigerant top-off from the last tenant’s handyman usually means a buried coil leak.
Our AC Repair team carries capacitors, contactors, and refrigerant for the nine brands we see most often in Bexar County neighborhoods. We don’t order parts from three counties away and make you sweat through another night.
Why Coldharbour Heating & Air Is Converse’s Preferred AC Repair Company
We’re independently owned and operated, part of the Kingswell network since 2003, and we work to standards most companies won’t put in writing. Every repair in Converse comes with a written price before any tool comes out of the truck, a firm arrival window, and our 365-Day Done Right Promise - if the repair fails within a full year, we return and correct it at no charge. The guarantee is on paper, not verbal.
Our technicians are background-checked, uniformed, and trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in Converse, where one street might have a 1995 Rheem and the next a 2018 Daikin, both needing same-day attention.
Phones are answered by a live person around the clock, every day of the year. No voicemail trees, no “call back in the morning” when your compressor seizes at 9 PM on a Saturday in July.
AC Not Blowing Cold Air in Converse
AC Not Blowing Cold Air is the most common call we get from Converse homeowners, and it almost always traces to one of three causes: a failed capacitor, low refrigerant from a leak, or a compressor that won’t start. In Converse’s 1980s-2000s tract homes, there’s a fourth factor we check first - attic ductwork so leaky it never delivers the cold air you’re paying to generate. Most repairs run $150-$650, and we diagnose before quoting.
Capacitor and Contactor Failures
The run capacitor is a small cylinder that jump-starts your compressor and fan motor. In Converse, where systems run 10-12 hours daily through June to September, capacitors bulge and fail predictably. We stock the common ratings for Rheem, York, and Bryant systems found locally. Replacement takes 30-45 minutes, and we test the compressor amp draw before leaving to catch a motor that’s working too hard.
Refrigerant Leaks and Coil Problems
Low refrigerant means a leak somewhere. In Converse’s military-rental market, we frequently find R-22 systems that prior handymen “topped off” with substitute blends - a patch that masks a leaking evaporator coil and leaves the next tenant with warm air a month into the lease. We leak-search with electronic detectors and nitrogen pressure tests, then document what we find so you know whether you’re looking at a repair or a system replacement.
AC Maintenance in Converse
AC Maintenance in Converse is preventive work that pays for itself in systems that last longer and fail less often in peak summer. A tune-up runs $80-$200, takes 60-90 minutes, and includes a written report of what we actually found - not a sales pitch. We recommend it every spring, before the sustained 95-100°F heat that defines Converse summers.
What the Tune-Up Covers
We clean the condenser coils, check refrigerant charge against manufacturer specs, test all electrical connections, measure amp draw on motors, and inspect the evaporator coil for buildup. In Converse’s older homes, we also spot-check attic duct seams with a smoke pencil - we’ve found 30% leakage in systems that “seemed fine” to the homeowner because the condenser ran constantly to compensate.
The PCS Turnover Problem
Military families near JBSA-Randolph move every 2-3 years. That means AC systems often go unserviced between tenants, and new renters inherit equipment with no maintenance history. Our tune-up includes documentation of refrigerant type, charge level, and any prior substitute blends - a written baseline that protects the next tenant and the landlord’s investment.
Trusted Brands We Service in Converse
Our trucks carry common parts for Rheem, York, Daikin, and Bryant - four brands we see constantly in Converse’s builder-grade housing stock. Rheem and York dominated the 1990s installs; Daikin and Bryant appear more in the 2000s builds and recent replacements. We don’t special-order a capacitor and make you wait three days. If your system is one of the nine major brands we train on, the technician who shows up can work on it. That includes Carrier, Trane, Lennox, Goodman, and American Standard for the brands not named above.
Common AC Repair Problems We See in Converse Homes
- Attic ductwork leaking 20-30% of conditioned air. Converse’s slab-on-grade tract homes route flex duct through unconditioned attics that hit 140°F in July. After 20-40 years, tape fails and seams open. The condenser runs all day, homeowners blame the unit, and the real problem is duct leakage masking as low refrigerant.
- R-22 systems with substitute refrigerant blends hiding coil leaks. Prior handymen top off leaking systems with MO99 or other R-22 substitutes to get through a lease turnover. The next tenant gets cold air for six weeks, then nothing. We document these systems before any repair commitment.
- Failed capacitors in original air-handler closets. Converse’s 1980s-1990s builds tucked air handlers into small closets with poor ventilation. Heat kills capacitors faster. We see this weekly in the neighborhoods between FM 78 and Gibbs Sprawl Road.
- Undersized electrical panels blocking modern replacements. Original 100-amp panels in older Converse homes can’t handle the locked-rotor amps of a modern heat pump or the heat strips needed for a February 2021-style freeze event. We flag this before quoting any system swap.

FAQs About AC Repair in Converse
A “top-off” without leak repair means refrigerant is escaping through a hole in the evaporator coil or line set. In Converse’s military-rental market, prior handymen often use R-22 substitute blends that work temporarily but mask the underlying leak. When the charge drops again, the system can’t absorb enough heat to cool your home. We leak-search with electronic detection and nitrogen pressure testing, then give you a written diagnosis - repair or replace - before any work begins. Call (817) 402-2972 for a free estimate.
Because the original 3-ton unit was probably oversized or undersized for the actual load, and the ductwork has changed condition over 40 years. Converse’s 1980s slab-on-grade homes often have attic ducts leaking 20-30% of their air, meaning a new 3-ton unit still can’t deliver comfort. We perform a Manual J load calculation and duct evaluation before recommending any replacement. A new system matched to the real load, with sealed ducts, performs better and costs less to run. The written price includes both calculations.
Warning signs include a humming outdoor unit that won’t start, intermittent cooling, or a fan that spins only after you give it a push. In Converse, where systems run 10-12 hours daily in peak summer, capacitors typically show stress by July or August. We test capacitance and microfarad ratings during every tune-up and carry replacements for Rheem, York, Daikin, and Bryant systems on our trucks. A failing capacitor left unattended can damage your compressor, turning a $200 repair into a $3,500 replacement. Call (817) 402-2972 if you notice these symptoms.
Many do. Original 100-amp panels in 1980s-1990s Converse tract homes can’t supply the locked-rotor amps a modern heat pump demands on startup, or the auxiliary heat strips needed when temperatures drop below 35°F. The February 2021 freeze proved this painfully. We check panel capacity, wire gauge, and breaker sizing as part of any replacement quote. If an upgrade is needed, we include it in the written price - no surprise add-ons at installation.
Our tune-up includes coil cleaning, refrigerant charge verification, electrical connection testing, motor amp draw measurement, and duct leakage spot-checking. For military rentals near JBSA-Randolph, we also document refrigerant type and any substitute blends found, creating a written baseline for the next tenant and landlord. This prevents the cycle of unknown repair history that defines so many Converse service calls. Tune-ups run $80-$200. Call (817) 402-2972 to schedule before peak summer hits.
