What does a Houston HVAC contractor do, and when should you call one?
A Houston HVAC contractor installs, repairs, maintains, and troubleshoots the systems that keep your home cool in long Gulf Coast summers and safe during winter cold snaps. In practical terms, that means AC repair when the system blows warm air, heating service when a furnace or heat pump stops producing heat, system replacement when an older unit is draining money, and maintenance when you want to catch capacitor, drain-line, or airflow issues before they turn into a no-cool emergency. 75 Degree AC handles residential and light commercial HVAC work across Houston with licensed service, same-day scheduling in many cases, and clear pricing before the job begins. Our team has served the city since 2016, and our Google profile currently shows a 5.0 rating across 230 reviews. For immediate help, call (713) 598-2737.
What Houston Customers Say About Our HVAC Service
Professional HVAC Services in Houston TX by a Local HVAC Contractor
75 Degree AC provides professional HVAC services for residential and light commercial properties in Houston TX. Our work covers cooling, heating, and full HVAC system support, with a focus on proper diagnostics, correct installation, and dependable long-term performance.
AC Repair
If your system is blowing warm air, short-cycling, freezing up, leaking water, tripping breakers, or making a hard-start noise, we diagnose the problem at the component level and tell you what failed. That includes capacitors, contactors, blower motors, condenser fan motors, thermostat controls, drain lines, low airflow, and refrigerant-related issues.
HVAC maintenance
Most Houston systems run long enough each year that maintenance is not optional if you want to avoid preventable summer failures. Tune-ups catch weak capacitors, airflow restrictions, dirty coils, drain-line buildup, and thermostat problems before they become after-hours calls.
AC installation and replacement
Houston homes punish oversized and undersized systems in different ways. Oversized units short-cycle and leave humidity behind. Undersized units run too long and wear out early. We install and replace systems based on load, airflow, and equipment fit, not whatever size happened to be in the house before.
Heating service
Houston heating problems show up fast during short cold snaps because many homeowners do not run the heat for months at a time. We service furnaces, heat pumps, thermostats, and heating airflow issues so you are not left troubleshooting on the first cold morning of the season. Start with Heating Services Houston
Indoor air quality
Humidity, dust, attic leakage, filtration problems, and duct contamination all affect comfort. If your home feels sticky even when the AC runs, or if one family member is always dealing with dust and allergy complaints, the issue may be airflow or filtration rather than just temperature. Our Air Quality & Systems services cover those problems directly.
Emergency AC repair
When your AC stops cooling in Houston heat, fast response matters more than anything else. Homeowners get urgent diagnostics, clear repair options, and 24/7 emergency service when immediate help is needed.

How our Houston HVAC service process works
You call and describe the problem
We ask what the system is doing, when it started, and whether the problem is cooling, heating, airflow, leaking, noise, or a total no-start condition.
We schedule the earliest practical service window
For many neighborhoods in Houston and nearby suburbs, same-day service is available depending on the time of day and current call volume.
We inspect the system and diagnose the cause
That can include electrical testing, capacitor checks, airflow evaluation, thermostat verification, drain inspection, refrigerant analysis, and performance testing.
We give you a written quote before work starts
No vague pricing. No hidden charge after the fact. You know what failed, what it takes to fix it, and what it costs.
We complete the repair or outline replacement options
If the system is a good repair candidate, we fix it. If it has moved into repeat-failure territory, we explain that clearly and show you the replacement path.
We test operation before the call is closed
The system is not just turned back on. We verify cooling or heating performance, airflow, controls, and final operating condition.
Why Houston homeowners call 75 Degree AC first
Most AC problems in Houston are not random. We see the same patterns every summer, failed capacitors after weeks of hard runtime, clogged condensate drains when humidity stays high, outdoor coils packed with debris, and low-airflow complaints from homes with older ductwork in hot attics. That matters because the fix depends on the actual cause, not the symptom. A system that is running but not cooling can need a capacitor, a contactor, a coil cleaning, a blower repair, a refrigerant leak test, or a thermostat correction. Guessing wastes money.
75 Degree AC is built around real diagnostics, not sales scripts. We give written quotes before work starts. We explain whether the issue is repairable, whether you are dealing with a pattern that is likely to repeat, and when a replacement actually makes more sense than another repair bill. If you live in Houston, Katy, Sugar Land, Cypress, Richmond, Pearland, or nearby areas, call (713) 598-2737 and we will walk you through the next step.

How much does an HVAC service call cost in Houston?
Our standard diagnostic fee is $85, and that fee is waived when you approve the recommended repair. Replacement estimates are free. Repair pricing in Houston depends on the failed part, system type, age of the equipment, accessibility, and whether the issue is isolated or tied to a larger performance problem. A capacitor replacement is a very different call from a blower motor failure, a refrigerant leak, or an aging system that has multiple weak components at once. One thing Houston homeowners should know: the expensive-sounding symptom is not always the expensive repair. Every summer we see homeowners panic about a “dead compressor” when the real problem is a capacitor or contactor. That is why diagnostic quality matters. Call (713) 598-2737 if you want a written quote before authorizing work.

How fast can 75 Degree AC respond for HVAC service in Houston?
75 Degree AC provides same-day HVAC service across Houston when scheduling allows, and emergency AC and heating calls are prioritized immediately. If your system stops cooling during Houston heat or your heater fails during a cold snap, we confirm your neighborhood, service type, and earliest arrival window on the call so you know what to expect before dispatch.
Same-day service matters in Houston because the city does not give you much room for delay once indoor temperatures start climbing. Heat index readings over 100°F are routine from late spring into early fall, and once a home starts absorbing attic heat, recovery gets harder every hour the system stays down. Emergency availability is part of our core service mix, not an afterthought, and our goal is to get you from a system-down problem to a real diagnosis as quickly as possible.

TRUSTED LOCAL HVAC COMPANY

What HVAC brands does 75 Degree AC service in Houston?
We work on the equipment Houston homeowners see most often: Carrier, Trane, Lennox, Goodman, Rheem, American Standard, and Daikin, along with common heat pump and mini-split configurations. Brand familiarity matters because diagnostics change from one platform to another. Some systems are more sensitive to airflow and coil conditions. Others have recurring board, contactor, capacitor, or drain-management patterns that show up repeatedly in Houston’s humidity and long cooling season.
If you already know your equipment brand and model, tell us when you call (713) 598-2737. That helps us prepare for the most likely failure points before the visit.
Meet Kenny Ho, the technician Houston customers keep naming in reviews
Kenny Ho is the name that keeps showing up in customer feedback for 75 Degree AC, and that matters. Homeowners mention him because he explains what failed, does not push work that is not needed, and handles both repair calls and major installs with the same straightforward approach.
That kind of technician credibility is hard to fake on a homepage. It shows up when a customer says Kenny replaced two AC units and the job stayed on time and on budget. It shows up when another customer says he fixed a furnace without trying to sell extras. It shows up when an AC repair caller says he was prompt, knowledgeable, and honest. Those are the signals people trust when they are deciding who to let into their house.
Frequently Asked HVAC Questions in Houston TX
Why is my AC running but not cooling my home in Houston?
In Houston, long run times put extra stress on air conditioning systems. Common causes include airflow restrictions, low refrigerant, dirty coils, or electrical components struggling under heat load. A proper system diagnostic helps identify the real issue before it turns into a larger failure.
How do I know if I need AC repair or full replacement?
If the system still cools but struggles to keep up, cycles frequently, or needs repeated repairs, AC repair may still make sense. Replacement becomes a better option when cooling is inconsistent, repairs are frequent, or the system can’t handle Houston’s summer demand. A system evaluation helps decide the most practical option.
Do you offer same-day AC repair in Houston?
When scheduling allows, same-day or next-day service may be available, especially during high heat periods. Response time depends on call volume and system condition, but urgent cooling issues are prioritized whenever possible.
What causes uneven cooling in Houston homes?
Uneven temperatures are common in Houston and are often linked to ductwork issues, airflow imbalance, insulation gaps, or system sizing. Even a working AC system can struggle if air distribution is uneven. Addressing airflow often improves comfort quickly.
Is AC maintenance really necessary in Houston?
Yes. Air conditioning systems in Houston operate longer than in many other regions. Routine maintenance helps reduce breakdowns, improves airflow, and allows small issues to be corrected before extreme heat exposes them.
How much does an HVAC service call cost?
The standard HVAC service fee is $85, which covers system evaluation and diagnostics. This fee is waived when a repair is completed, so customers aren’t charged twice for the same visit.
Do you provide free estimates for HVAC system replacement?
Yes. When replacement is recommended, we provide free estimates on new HVAC system replacement so homeowners can review options clearly and plan without pressure.
Are there any discounts available?
Yes. A 5% senior discount is available on qualifying HVAC services. Discounts are discussed during the service visit so pricing stays clear and upfront.
Can ductwork issues affect AC performance?
Absolutely. Leaking, damaged, or poorly designed ductwork can reduce cooling, cause hot spots, and strain the system. Even newer AC units won’t perform properly if airflow is restricted or conditioned air is escaping.
Do you service both residential and commercial HVAC systems?
Yes. We provide HVAC services for residential homes as well as light commercial properties such as offices and retail spaces. Service recommendations are based on how each system is designed and used.
What should I do if my AC stops working completely?
Turn the system off to avoid damage and schedule service as soon as possible. Avoid resetting breakers repeatedly or forcing the system to run. A diagnostic inspection is the safest way to identify what caused the shutdown.
