Our AC Repair, Installation & Maintenance Services in Houston, TX
AC Repair
Had your AC stopped cooling in the middle of a hot week? AC repair Services in Houston is what we do every day. Most faults come down to a failed capacitor, refrigerant leak, or a frozen evaporator coil and we find the exact cause before quoting any work. Call us and we will have a technician out the same day.
Central AC Repair
Central AC repair covers the full system from the condenser outside to the air handler inside. A burnt contactor, failing blower motor, or refrigerant pressure drop are the most common faults we find on service calls. We run a full electrical and pressure check before touching anything and give you a written quote on the spot.
Mini-Split AC Repair
Mini-split AC repair is not always straightforward because the fault can sit in the indoor unit, the outdoor unit, or the communication between the two. Dirty evaporator coils, refrigerant leaks, and sensor errors are the issues we find most on mini-split calls. We diagnose the exact problem and fix only what needs fixing.
Heat Pump AC Repair
Heat pump AC repair covers both sides of the system because a heat pump handles your cooling and heating from one unit. The most common faults we find are a failed reversing valve, low refrigerant charge, and a defrost cycle that will not complete. We test the full system before recommending any repair so nothing gets missed.
Emergency AC Repair
AC stopped working on a hot day and you need someone out fast? Emergency AC repair is available the same day across Houston seven days a week. We show up, run a full diagnostic, and give you a written quote before any work starts. No overtime charges, no hidden fees.
AC Compressor Repair
AC compressor repair starts with confirming the compressor is actually the problem because a failed compressor is the most expensive fault in any cooling system. We check refrigerant charge and electrical supply first before recommending repair or replacement. A proper diagnosis here saves you from spending money on the wrong fix.
AC Installation
Thinking about a new AC system for your home or business? AC installation in Houston starts with a Manual J load calculation to make sure the new system is sized correctly for your property. An oversized or undersized unit costs more to run and wears out faster than one that is properly matched.
Central AC Installation
Central AC installation covers the full setup including the new condenser, air handler, refrigerant lines, and electrical connections. Every install is sized to your property and all work carries a full manufacturer warranty plus our labor warranty. We clean up completely before we leave and walk you through the new system before the job is closed.
Mini-Split Install
Need cooling in a room addition, garage, or a space with no existing ductwork? Mini-split installation gives you precise temperature control without running new ducts through the property. We install single-zone and multi-zone systems with inverter technology that adjusts output in real time instead of cycling at full power.
Heat Pump Install
Heat pump installation gives your property cooling and heating from a single unit which makes it one of the most practical upgrades for Houston homes. New installs on high-efficiency SEER2 rated systems qualify for CenterPoint Energy rebates which brings the upfront cost down. We handle the full install from sizing to the final system test.
AC Leak Repair
AC leak repair has to be done at the source because a refrigerant leak does not fix itself. The longer it goes unaddressed the more it reduces cooling output, raises energy bills, and strains the compressor. We locate the leak, fix it properly, and recharge the system to the correct refrigerant level using our certified technicians.
AC Replacement
AC replacement makes more financial sense than repair when the system is over 10 to 12 years old, running on R-22 refrigerant, or has had three or more component failures in recent seasons. We size every replacement using a Manual J load calculation so you get a system that actually fits your home, not just the same unit swapped back in.
AC Tune-Up and Maintenance
AC tune-up and maintenance is the easiest way to avoid a breakdown in the middle of summer. A proper service covers refrigerant charge verification, capacitor test, coil cleaning, condensate drain flush, thermostat calibration, and static pressure check. Schedule it once a year before cooling season and catch small issues before they turn into expensive repairs.
Ductless AC Install
Ductless AC installation is the right call when there is no existing ductwork or when you need independent temperature control in a specific area. Single-zone and multi-zone configurations are available depending on the layout of your property. We handle everything from sizing to installation and final performance testing.
AC Troubleshooting
Not every AC problem is obvious. Short cycling, warm air from vents, unusual noises, or a system that runs constantly without hitting the set temperature all point to different faults. We run a full AC troubleshooting & Diagnosis to find the actual cause before recommending any repair or replacement so you are not paying to fix the wrong thing.
Commercial AC
Got a business property that needs reliable cooling? Commercial AC Service in Houston covers rooftop units, package units, and commercial split systems for offices, retail spaces, restaurants, and medical facilities. Preventive maintenance agreements are available so building managers get scheduled visits and priority response without chasing down a contractor every season.
Residential AC
Residential AC Service covers everything a Houston home needs including repair, installation, replacement, and maintenance. All work is carried out by licensed and insured technicians and every job comes with a written quote before work starts. We serve single-family homes and multi-family properties across all Houston service areas.

What Professional AC Service Actually Does for Your System
Most AC problems do not start with a complete breakdown. They start small. A capacitor reading low, a condensate drain slowly blocking, refrigerant dropping just enough to make the system work harder than it should. A licensed AC contractor catches these before they turn into a failed compressor or a system that quits on the hottest day of the year.
Every AC service call at 75 Degree AC starts with a full diagnostic performed by licensed and insured technicians. We check electrical components, measure refrigerant pressure, inspect the evaporator coil, and test static pressure across the system. That process tells us exactly what is wrong and what shape the rest of the system is in before any repair is recommended or priced.
Regular AC service in Houston also extends the life of the equipment. A system that gets a proper tune-up from a certified AC contractor every year runs more efficiently, draws less power, and lasts longer than one that only gets attention when something breaks. For Houston homeowners and businesses that run their AC hard, that difference adds up over time.

Frequently Asked Questions FAQ's
How often should an air conditioning system be serviced in Houston?
Once a year before cooling season is the standard. Houston systems run longer and harder than most, so annual maintenance catches worn capacitors, low refrigerant charges, and dirty coils before they cause a breakdown in peak summer heat.
What are the signs that an AC system needs repair or replacement?
Warm air from the vents, weak airflow, short cycling, unusual noises, water pooling near the indoor unit, and a sudden spike in energy bills are all warning signs. A system over 10 to 12 years old showing any of these issues is worth having a technician evaluate for replacement.
How long does a professional AC repair take in Houston?
Most repairs are completed on the same visit once the diagnostic is done and the quote is approved. Complex jobs involving refrigerant work or major component replacement may take longer depending on parts availability.
What does an AC tune-up service include?
A proper tune-up covers refrigerant charge verification, capacitor test, coil cleaning, condensate drain flush, thermostat calibration, static pressure check, and filter inspection. If those items are not on the checklist, it is not a full tune-up.
How do you size a new AC system correctly for a Houston home?
Correct sizing requires a Manual J load calculation that accounts for square footage, insulation, ceiling height, window placement, and occupancy. A system sized by guesswork alone will short cycle, waste energy, and wear out faster.
What causes an AC system to stop cooling even when it is running?
Common causes include a refrigerant leak, a failed capacitor reducing compressor output, a frozen evaporator coil from restricted airflow, or a dirty condenser coil that cannot release heat. A full diagnostic identifies the exact fault before any repair is quoted.
Can 75 Degree AC install a new system for both homes and businesses?
Yes. We handle AC installation and replacement for residential properties and light commercial buildings including offices, retail spaces, and restaurants across Houston and surrounding areas.
What should I check before calling for an AC repair?
Check the thermostat settings first, then check the circuit breaker. Replace the air filter if it has not been changed recently. If the system still will not cool or will not turn on after those steps, the issue is likely internal and needs a licensed technician to diagnose it properly.
About Houston, TX
Houston runs on its own terms. It is the fourth largest city in the United States and the energy capital of the world, home to more Fortune 500 companies than any other American city outside New York. The Texas Medical Center, the largest medical complex on the planet, sits right in the middle of it. NASA’s Johnson Space Center is down the road. This is a city built around serious industry.
The people here are just as diverse as the economy. Over 145 languages are spoken across Houston’s neighborhoods, from the Heights to Midtown to Alief. The food scene reflects that directly. Some of the best Vietnamese, Mexican, Indian, and West African food in the country is found right here. No other city in Texas comes close to Houston’s range.
The neighborhoods spread across a massive footprint with no zoning laws, which means Houston grew fast and grew wide. Older bungalows sit next to new construction. Historic districts border commercial corridors. Every area has its own character. Summers are long, hot, and humid. The kind of heat that puts real demand on air conditioning systems from April through October and keeps HVAC contractors busy year round.
