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.

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.
