Houston summers don’t forgive a weak AC system. Refrigerant leaks, failed capacitors, frozen evaporator coils, and clogged condensate drains are all common problems we fix every week.

AC Repair & Installation in Houston, TX
AC repair in Houston and AC installation both start the same way. A technician runs a full diagnostic before any work is recommended or priced. We service all major systems, including central air conditioning, mini-split units, and ductless systems. The right fix gets applied regardless of what is running in your home or building.
Emergency AC Repair
When your AC stops working, it usually comes down to a failed capacitor, tripped breaker, frozen coil, or a compressor that won’t start. We run a full electrical and refrigerant diagnostic on every Emergency AC Repair service to find the exact fault before touching anything. Most repairs are completed on the same visit once the quote is approved.
AC Compressor Repair
The compressor is the most critical part of your cooling system. When it fails, the system stops producing cold air entirely. During AC Compressor Repair, we diagnose compressor faults, check refrigerant charge and electrical supply, and give you an honest assessment on repair or replacement that makes more financial sense.
AC Leak Repair
Refrigerant leaks reduce cooling output, raise energy bills, and put strain on the compressor over time. With AC Leak Repair, we locate the leak, repair it at the source, and recharge the system to the correct refrigerant level. All refrigerant work is handled by certified technicians.
AC Troubleshooting
Not every AC problem is obvious. If your system is short cycling, blowing warm air, making unusual noises, or running constantly without reaching temperature, our AC Troubleshooting process runs a full diagnostic to find the actual cause before recommending any repair.
Central Air Conditioning Repair
Most calls come down to the same parts: a failed capacitor, burnt contactor, refrigerant leak, or a blower motor pulling too much current. For Central Air Conditioning Repair, we run an electrical test and refrigerant pressure check before quoting anything certified, diagnostic first. You get a written quote on-site. Nothing gets touched without your approval.
AC System Replacement
If your system is over 10 to 12 years old, on R-22 refrigerant, or has had three or more component failures, AC System Replacement makes more financial sense than another repair. We run a Manual J load calculation on every job so the new system is properly sized, not just swapped out. Most installs qualify certification and CenterPoint Energy rebates.
Mini-Split & Ductless AC
Ductless mini-split systems are built for room additions, garages, server rooms, and spaces without existing ductwork. Our Mini-Split & Ductless AC service installs Mitsubishi, Daikin, and Fujitsu systems using inverter technology that adjusts output in real time instead of cycling at full power.
AC Tune-Up & Maintenance
An AC Tune-Up & Maintenance in Houston covers refrigerant charge verification, capacitor test, coil cleaning, condensate drain flush, thermostat calibration, and static pressure check. Schedule it once a year before the cooling season hits. A maintenance agreement is available for priority scheduling and reduced repair rates.

Air Duct Repair & Sealing in Houston
Duct leakage forces your system to work harder, run longer, and consume more energy just to hit the temperature you set. We handle air duct repair, air duct replacement, and duct sealing across residential and light commercial properties.
Air Duct Repair
Fixing crushed flex duct, disconnected joints, pest damage, or deteriorated duct insulation restores proper static pressure across the system and improves overall performance without touching the equipment itself.
Air Duct Replacement
Makes sense when ducts are undersized, heavily deteriorated, or laid out inefficiently. New duct systems are completely sized to Manual D specifications and thoroughly tested for leakage before completion.
Duct Sealing & Air Purification
Mastic sealant is applied at joints, boots, and connections to cut energy loss. We also install whole-home air purification systems like UV lights and high MERV-rated filtration directly into your duct network.
