We’ve been driving to Houston homes since 2018. From Meyerland to Memorial, from Braeswood Boulevard to the brick-veneer ranches of southwest Houston, we know the houses. We know the attics that hit 150°F in July. We know the original ductwork laid directly on those attic floors back in 1985, the capacitors that cook to death in the heat, and the condensate drains that clog with algae before Labor Day. When your system goes down in Houston, you’re not just uncomfortable - you’re fighting Gulf humidity that turns a 78°F house into a sauna. We answer the phone 24 hours a day, every day, with a live person. No voicemail tree. No “press 1 for service.” Just someone who can get a technician to your door.

Our AC Repair & Installation Services in Houston
AC Repair
Houston’s combination of extreme Gulf-driven humidity and attic-installed air handlers destroys capacitors and refrigerant lines faster than almost anywhere in the country. Dew points routinely hit 75-80°F from May through September, and your attic bakes to 130-150°F. Our crew replaced a failing Trane compressor in a 1980s brick-veneer home on Braeswood Boulevard, where the original ductwork had been laid directly on the attic floor. The system was short-cycling because of a degraded capacitor - common in Houston’s attic heat - leaving the home clammy at 78°F with 70% humidity. We installed a correctly sized 3-ton unit and sealed the flex ducts, dropping humidity below 50%.
Most AC repairs in Houston fall between $150-$650. A failed capacitor might run $150-$350. A refrigerant recharge with leak detection runs higher. We diagnose before we quote, and we quote before we work.
AC Installation
New AC installation in Houston demands more than square-footage math. An oversized unit short-cycles, dropping the thermostat reading while leaving relative humidity above 65-70%. That’s the clammy, mold-prone condition that generates callbacks. We size for latent heat load - dehumidification first, cooling second - because that’s what Houston’s Gulf proximity demands.
Standard installation for a Houston home runs $3,500-$7,500. This includes removal, disposal, new pad, electrical connections, and commissioning. We seal ductwork as standard, not as an upsell. And we manage attic heat load because a correctly sized and installed system in Houston will outlast an identically spec’d unit in Dallas or San Antonio by years.
AC Replacement
Replacement becomes the straight talk when repair costs approach half the value of a new system, or when your 15-year unit still uses R-22 refrigerant. In Houston’s 1970s-1990s housing stock - especially Meyerland, Memorial, and southwest Houston - we often find aging original ductwork that undermines even a new compressor. We tell you honestly whether replacement makes sense, and we never sell you a system you don’t need.
Refrigerant Recharge
Low refrigerant means a leak, period. In Houston’s heat, refrigerant lines degrade from the outside in - thermal expansion, vibration, and attic heat stress the copper. We find the leak, repair it, and recharge to factory spec. A recharge without leak repair is throwing money into your condensate drain.

Common AC Repair & Installation Problems We See in Houston Homes
- Compressor failure from capacitor degradation in 130-150°F attics. Houston’s near-universal practice of installing air handlers in attics means capacitors operate at extreme temperatures for months straight. A $25 part fails, and the compressor overheats trying to start. We check capacitors on every service call because we’ve seen too many compressors die from a preventable $200 repair.
- Duct insulation breakdown in attic floor ductwork causing thermal loss and humidity issues. Original flex duct laid on Houston’s superheated attic floors degrades in 10-15 years. The insulation compresses, the vapor barrier cracks, and your cooled air warms before it reaches the register. We see this in Memorial and Meyerland ranch homes constantly.
- Condensate drain clogs from algae and biofilm triggered by constant runtime and humidity. This is so endemic in Houston that we treat a flush and pan-tab treatment as standard on every tune-up, not an upsell. Year-round heat, 2,400+ hours of annual runtime, and ambient humidity turn neglected drain pans into a petri dish within one season. Float switches shut the system down, or worse - water damages your ceiling.
- Short-cycling from oversized equipment in older Houston homes. Many 1980s installations were sized for the house as built, before energy-efficient windows and added insulation. The unit blasts cold air, satisfies the thermostat quickly, and shuts off before dehumidifying. You feel clammy. Mold risk rises. We measure load properly and right-size when we replace.
Pricing for AC Repair & Installation in Houston, TX
Here’s what AC work costs in Houston’s market. These are real ranges, not teaser rates.

What moves the needle? Attic accessibility affects labor time. Ductwork condition determines whether sealing suffices or replacement is needed. Electrical panel capacity may require an upgrade for modern high-efficiency units. And Houston’s humidity means we always verify dehumidification performance before we sign off - that’s non-negotiable for us.
We offer $50 off any repair over $250, a free second opinion on any written estimate, and $89 seasonal tune-ups. Seniors and veterans receive 5% off, always. Call (833) 313-7291 for your exact quote. Estimates are free.

FAQs - AC Repair & Installation in Houston
Ice on your evaporator coil almost always means restricted airflow or low refrigerant, and Houston’s humidity makes the freeze-up faster and thicker. When warm, moist Gulf air can’t move across the coil properly, the coil temperature drops below freezing and builds ice that blocks airflow completely. We check filter condition, blower operation, and refrigerant charge - the three culprits - and we clear the ice properly so you don’t damage the compressor. Call (833) 313-7291 and we’ll diagnose it today; estimates are free.
In Houston, flush your condensate line annually and replace flexible sections every 3-5 years due to algae and biofilm buildup. The combination of year-round heat, near-constant runtime, and 75-80°F dew points creates conditions found almost nowhere else; neglected drains clog within a single season. We include flush and pan-tab treatment in our $89 tune-up because we’ve seen too many ceiling collapses from backed-up drain pans. Book a tune-up at (833) 313-7291 and we’ll handle it.
Yes, a two-stage or variable-speed system is worth the investment for most Houston homes because it runs longer at lower capacity, removing far more humidity than single-stage equipment. Houston’s latent heat load often exceeds sensible heat load on mild days, and an oversized single-stage unit short-cycles, leaving you clammy at 78°F. We size for your actual load and recommend two-stage when the budget allows - the comfort difference is immediate, and energy savings typically recover the premium in 5-7 years. Call (833) 313-7291 for a load calculation and honest comparison.
Your attic unit fails faster because Houston’s attics reach 130-150°F while simultaneously housing equipment that must dehumidify 75-80°F dew point air - a double threat found almost nowhere else. Capacitors, refrigerant lines, and duct insulation all degrade faster under thermal stress, and the lack of basements means virtually no Houston homes have conditioned mechanical rooms. A correctly sized system with proper attic heat load management will outlast a poorly installed identical unit by years. We address this on every installation. Call (833) 313-7291 for an assessment of your attic setup.
Replace degraded ductwork when it’s laid on the attic floor, has crushed or separated flex connections, or shows visible insulation breakdown - conditions we find constantly in 1970s-1990s Houston homes in Meyerland, Memorial, and southwest Houston. New ductwork sealed to modern standards typically pays for itself in 3-5 years through reduced cooling load and improved humidity control. We inspect your ductwork before every installation and tell you straight whether it can be sealed or needs replacement. Call (833) 313-7291 for a free evaluation with your replacement quote.
