Carrier builds some of the most efficient residential equipment on the market. The Infinity line in particular runs on closed-loop communicating controls that talk between thermostat, indoor unit, and outdoor unit. That sophistication is exactly why generic service can go sideways. Houston’s humidity and salt air add another layer: coils corrode faster here, condensate drains clog more often, and voltage sags from storm season push variable-speed boards into fault codes that a parts-swapper will misread. If you need AC Repair, we diagnose by the actual fault history and the unit’s behavior, not by swapping parts until something sticks. We diagnose by the actual fault history and the unit’s behavior, not by swapping parts until something sticks.
A note up front: Dalton Heating & Air Houston is an independent Carrier service provider. We are not affiliated with or authorized by Carrier Corporation. What that means for you is simple: we fix what’s broken, we recommend what’s honest, and we stand behind the repair in writing for a full year.
Why Trust Dalton Heating & Air Houston for Your Carrier HVAC?
Our techs see Carrier equipment every week, not occasionally. The difference shows when an Infinity system throws a low-voltage communication fault, or a Performance heat pump’s inverter board won’t restart after a brownout. You can’t learn those failure patterns from a spec sheet. You learn them from pulling panels off hundreds of these units in Houston attics and backyards, in July, when the condenser is 140 degrees and the homeowner has been without air for six hours.
Marco Benitez, owner of Dalton Heating & Air Houston, learned HVAC fundamentals at Los Angeles Trade-Technical College and has spent the better part of two decades in the trade. His crew has logged years of Houston-specific service, including a lot of calls out near the Energy Corridor and into Carrier repair in Baytown territory where summer loads push older Carrier equipment hard. Marco’s approach: diagnose the actual cause, a low refrigerant charge, undersized ductwork, a failing capacitor, then explain it in plain terms. As he puts it: “Tell me what the system is doing, and I’ll tell you what it needs – not what sells.”
Every Carrier repair we perform includes the same terms, in writing, every time: the price is fixed before work starts, the repair is guaranteed for a full year, and if the fix doesn’t hold within that year, we return at no charge. That’s The Garrison Standard, and it’s non-negotiable on every job we run.
Styles & brands we work with
Common Carrier HVAC Problems We Fix in Houston
- Infinity communicating control lockouts on hot restarts (ICS/59MN7 furnaces). The ECM blower module on variable-speed Infinity furnaces can fail after repeated hot restarts, especially when the system cycles hard during Houston’s shoulder seasons. The thermostat shows a system malfunction, the blower won’t ramp, and a lot of techs condemn the board. Often it’s the blower module. We check the fault history first, then the module, before quoting a board.
- Code 83/84 brownout faults on Infinity 19VS variable-speed AC units. Houston’s grid gets storm-sagged in spring and early summer. Voltage dips throw the 19VS into brownout protection, and the communicating control locks out. If you see code 84 or a blinking yellow LED on the outdoor unit, it’s rarely a failed compressor. It’s the control reacting to the grid. We verify line voltage, tighten low-voltage connections, and clear the lockout, then test the inverter. We don’t sell you a compressor for a voltage sag.
- Cracked heat exchangers on older 58MVP and 58MXA 90% furnaces. Those two-stage 90% models were workhorses, but condensation pooling near the coast accelerates rust at the secondary heat exchanger seams. A cracked exchanger leaks carbon monoxide into the airstream. That’s a genuine safety issue. We test with a combustion analyzer, not just a visual. If it’s cracked, the furnace is done, and we’ll show you the replacement math before you spend another dollar on repairs.
- Evaporator coil leaks on 24ABC6 and 24ACC6 Performance units. Formicary corrosion, tiny pinholes caused by chemical reactions in the coil’s copper tubing, is worse in Houston than almost anywhere else because of our constant humidity. A slow leak drops the refrigerant charge, the system runs longer to hit setpoint, and your electric bill climbs. We find the leak with an electronic detector, confirm the exact coil model, and quote either a coil replacement or a refrigerant recharge with leak seal depending on the coil’s age and condition.
- Condensate drain clogs on every Carrier line. Houston air carries so much moisture that evaporator coils pull gallons of water out of the air daily. Algae and sludge build up in the drain pan and trap line. A clogged drain backs water into the secondary pan, and if the float switch fails, into your ceiling. We clear the line, treat the pan, and check the float switch on every tune-up. On slab-foundation Houston homes, that clogged drain is a ceiling repair waiting to happen.
These are the failures we see over and over in Houston. Not the generic stuff from a nationwide service franchise’s training manual. The real patterns, from the actual equipment, in this specific climate.
Carrier Parts & Our Repair-vs-Replace Approach
For Carrier Infinity and Performance systems, we stock genuine Carrier OEM boards, sensors, and blower motors locally. These are the parts where an aftermarket equivalent can create communication mismatches or early failures. For common wear items, capacitors, contactors, universal ignitors, we use quality aftermarket parts that meet or exceed spec, because charging you factory prices for a $15 capacitor doesn’t make sense and we won’t do it.
Here’s our repair-vs-replace rule, stated plainly: we repair first when the compressor and heat exchanger are sound. A failing capacitor, a clogged drain, a dirty flame sensor, a stuck reversing valve, these are repairs. A 15-plus-year-old Carrier with a failed ECM blower module or a leaking evaporator coil? We show you the replacement cost and the likely next failure before you sink another $600 into a unit that’s aging out. On a 108°F Tuesday in Katy, our tech found a Carrier Infinity 19VS throwing code 84 and a locked blower. We replaced the failed ECM module with an OEM Carrier part, tightened the low-voltage connections, and had the system modulating at 18% within 90 minutes. No board swap, no compressor scare, no upsell. The system needed a $400 module, not a $9,000 condensing unit. That’s the difference between diagnosing and guessing.
Call (903) 494-7686 and we’ll give you the same straight read on your Carrier system.
Our Carrier Service Process – Step by Step
- 1
Diagnosis from fault history and live data, not guesswork. We start by pulling the stored fault codes from the thermostat or control board, then confirm with live readings: pressures, temperatures, amp draws, and voltage at the component. On Infinity systems, we use the communicating control’s own diagnostic interface. No parts get swapped until we know what failed and why.
- 2
Written price before any work starts. Once we’ve found the fault, you get the repair cost in writing, with parts and labor separated. You approve the price before a single screw turns. That’s The Garrison Standard, and it applies to every job we run, no exceptions.
- 3
Repair or installation using the right parts. OEM Carrier parts for communicating controls, blower motors, and sensors. Quality aftermarket for wear items. Every connection is tightened, every panel is reseated, and the work area is left clean. We don’t leave attic insulation scattered or a condenser pad looking like a parts yard.
- 4
Post-repair testing that proves the fix. We run the system through a full cycle, watch the temperatures stabilize, verify the refrigerant subcooling or superheat is in range, and confirm the fault codes are cleared. On variable-speed units, we watch the ramp-up and modulation to make sure the blower and compressor are talking properly.
- 5
Full-year written guarantee on every repair. The repair is guaranteed in writing for 365 days. If the same fault returns within that year, we come back at no charge. Not a 30-day courtesy window. A full year, in writing, as standard.

FAQs – Carrier HVAC Service in Houston
No. We are an independent Carrier service provider, not a Carrier-authorized dealer or factory service agent. That independence means we recommend what’s actually right for your system, not what a franchise agreement tells us to push. We carry genuine Carrier OEM parts and we know the equipment inside and out, but we answer to you, not to the manufacturer.
For critical components on Infinity and Performance systems, including communicating control boards, ECM blower modules, and sensors, we use genuine Carrier OEM parts. For common wear items like capacitors, contactors, and universal ignitors, we use quality aftermarket parts that meet OE spec at a lower cost. We’ll tell you which is which on the written estimate and why it matters for your specific repair.
Most Carrier repairs are completed in a single visit. A capacitor replacement or condensate drain clearing takes under an hour. An ECM blower module replacement on an Infinity furnace takes 90 minutes to two hours. A full evaporator coil replacement can run half a day because the system has to be pumped down, the coil swapped, and the charge weighed back in. During Houston’s summer peak, same-day and next-day appointments are usually available. Call (903) 494-7686 for today’s schedule.
We service the full residential lineup: Infinity (ICS/98/80 furnaces, 19VS/18VS AC, 20/19/18 heat pumps), Performance (59TP6/59SC5, 24ACC6/24ABC6, 25HCE4), Comfort (59SC2/59SU5, 24SCA4/24ACC4, 25HCC5), and the ductless 38MGRQ, 40MAHB, and 38MPRA lines. We also work on older discontinued models including the 58MVP and 58MXA furnaces. If you can read us the model number off the data plate, we can tell you what we’re dealing with.
No. Using an independent contractor does not void a manufacturer’s parts warranty. Carrier’s standard warranty covers parts, not labor, and it applies as long as the equipment is installed and serviced according to manufacturer specifications, which is exactly how we work. If your system is under a Carrier extended labor warranty, we’ll work with you and the warranty administrator on claims. We document every repair thoroughly so warranty paperwork is straightforward.
Infinity communicating systems store fault history in memory, and a power outage or brownout can trigger communication errors between the thermostat, indoor unit, and outdoor unit. On hot restarts after an outage, a failing ECM blower module on ICS or 59MN7 furnaces can lock out the system entirely. On Infinity 19VS AC units, a voltage sag during the outage often sets code 83 or 84, a brownout fault, which locks the outdoor unit until it’s cleared. The fix depends on the stored codes. Sometimes it’s a simple lockout reset and low-voltage connection tightening. Sometimes the blower module has failed and needs replacement. Call (903) 494-7686 and we’ll pull the fault history and tell you exactly what the system recorded.
It depends on what actually failed. An Infinity variable-speed compressor that won’t start is often a control or electrical issue, not a failed compressor. A brownout code, a blown inverter fuse, a failed start capacitor, or a communication fault can all mimic compressor failure. A trained tech checks the inverter board, wiring, and compressor windings before declaring the compressor dead. If the compressor itself has mechanically failed, replacement of the outdoor unit is usually the right call rather than replacing just the compressor on a variable-speed system. We’ll show you the test results and the math before you commit to anything.
Code 31 and 33 on Carrier furnaces are pressure switch faults. The pressure switch is a safety device that confirms the inducer motor is pulling combustion gases through the heat exchanger and out the flue. The switch can trip from a blocked vent, a clogged condensate trap, a failing inducer motor, or a bad switch. Clearing the code without fixing the underlying cause can leave the furnace running with an unsafe exhaust path. This is a safety component on a gas-burning appliance. We recommend a trained tech with a combustion analyzer, not a DIY attempt, because carbon monoxide exposure is the risk if the exhaust isn’t venting properly. Call (903) 494-7686 and we’ll check the entire exhaust path, not just the switch.
Yes. We service and install Carrier ductless systems including the 38MGRQ outdoor units and 40MAHB indoor heads, plus the 38MPRA multi-zone outdoor units. Ductless systems are common in Houston additions, garage conversions, and older pier-and-beam homes inside the Loop where running ductwork through limited closet space isn’t practical. The most common ductless issues we see are dirty blower wheels, clogged condensate pumps, and low refrigerant from flare fitting leaks. We stock common Carrier ductless parts and can usually repair these in one visit.
The honest answer: they shorten it. Houston’s 200-plus days of high humidity cause evaporator coils to condense water constantly, which feeds formicary corrosion, pinhole leaks in the copper tubing that slowly drop your refrigerant charge. Salt air near the coast accelerates corrosion on outdoor condenser coils and electrical connections. Most Carrier AC units in Houston last 12 to 15 years before a significant repair like a coil replacement becomes likely. Units that get annual maintenance, clean coils, clear drains, tightened connections, can push past 15. Units that are ignored usually don’t. Our tune-up is $80 to $200 per unit, and it catches the corrosion and clogs before they become a July emergency. Call (903) 494-7686 to schedule yours.
