What customers say about emergency ac repair
…Now, my A/C is running perfectly, much quieter when sitting on the porch, and it isn’t an eye sore like my old unit was. Now, I don’t have to stress anymore about emergency outages or paying for repair cost. They also provide a 10 year warranty. If you are having any sort of A/C issues, this is the only company l would use. Honesty and integrity go along way in my book and you can tell that is what they pride themselves on. Hard to find that these days

What customers say about emergency ac repair
I am always so very impressed with Aire Serve. I have been a customer for a few years and they keep my AC unit running smoothly with two visits per year. They also have helped out on several occasions when there was an emergency after a storm, or when there was an issue. They are prompt, courtesy and a good value. Highly recommend!

What Every Houston Resident Should Ask Before a Service Call
- What counts as an emergency AC repair vs. a regular service call?
- Total system failure on a 95°F+ day, refrigerant leak causing rapid loss of cooling, or fan/compressor seizure are emergencies. Tune-ups, slow cooling decline, and off-season checks don't qualify for emergency rates.
- Should I expect a premium for after-hours or weekend dispatch?
- Most providers add $150–$300 over the standard diagnostic fee for evenings, weekends, and holidays. Ask for the premium before they dispatch — a few shops publish flat-rate emergency pricing, and the gap can be $400+ on the final bill.
- When is the peak season for HVAC maintenance in Houston?
- The busiest season for HVAC maintenance in Houston, Texas, occurs during the peak of summer and throughout the hurricane season from June through November. Extreme heat and tropical humidity cause high demand for emergency repairs and system tune-ups. Scheduling your annual maintenance well before the summer heat intensifies can help you avoid long wait times and ensure your system is prepared for the high-stress conditions common in our climate.
- How much does HVAC service cost in Houston, TX?
- AC repair typically runs $115–$535 in Houston, Texas. See the HVAC pricing table on this page for the full per-service breakdown.
