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.

Commercial HVAC Services in Houston

Commercial HVAC repair in Houston covers offices, retail spaces, restaurants, medical facilities, and light commercial buildings including rooftop units, package units, and commercial split systems. Preventive maintenance agreements are available for all commercial HVAC services in Houston, giving building managers scheduled visits, written reports, and priority response without chasing down a contractor every season.

Commercial AC repair in Houston covers rooftop units, package units, and commercial split systems across all property types. Commercial AC maintenance includes scheduled service visits, MERV filtration checks, coil cleaning, written service reports, and priority response under a service agreement.

Light commercial HVAC maintenance covers properties under 5 tons cooling capacity including small offices, retail units, strip centers, and small restaurants that need scheduled care without a full commercial contract. Each visit includes coil cleaning, air filter replacement, and a written service report at completion, handled by licensed HVAC contractors serving light commercial properties.

Commercial HVAC installation in Houston starts with a load calculation that accounts for occupancy load, square footage, and building envelope before any equipment is specified. Every installed system including rooftop units, package units, and commercial split systems carries a full manufacturer warranty plus a labor warranty on all installation work performed by our licensed installation team.

Heating & Furnace Repair in Houston, TX

As a licensed heating contractor in Houston, we service gas furnaces, electric furnaces, and heat pump systems for residential and light commercial properties. Every heating services call in Houston TX includes a combustion safety check and carbon monoxide test as standard, not an add-on.

Furnace repair in Houston most often comes down to a failed ignitor, cracked heat exchanger, faulty gas valve, pressure switch failure, or limit switch issues. Every furnace repair includes a carbon monoxide safety test and a full heat exchanger inspection before the job is closed. New furnace installation follows a load calculation for proper sizing, correct flue pipe venting, and is rated by efficiency so you know exactly what you are getting.

Heat pump repairs we handle most include refrigerant issues, reversing valve failure, defrost cycle problems, and capacitor faults that cause the system to lose heating or cooling output. Heat pump replacement qualifies for high-efficiency units and better performance, bringing the upfront cost down.

A proper HVAC inspection is delivered with the thermostat because incorrect temperature readings, failure to call for heating or cooling, and short cycling are regularly misdiagnosed as bigger system failures. We also install smart thermostats including Nest, Ecobee, and Honeywell, with full compatibility for zoned systems and correct wiring calibration on every job.

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 repairs most often involve crushed flex duct, disconnected joints, pest damage, or deteriorated duct insulation that cuts off supply or return airflow. Fixing these 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 for the system, heavily deteriorated, or laid out in a way that was never correct for the home. New duct systems are sized to Manual D specifications and tested for leakage before the job is closed.

Duct sealing for commercial and residential properties in Houston uses mastic sealant applied at joints, boots, and duct connections to cut energy loss without requiring full replacement. We also install whole-home air purification systems including UV light units and MERV-rated filtration directly into the duct system to reduce allergens and improve indoor air quality.
