The representative, Tommy was very knowledgeable, patient, & honest. As perspiration dripped down his face being that the house was so hot - he explained the process of what was the cause, & what it would take to repair it. I'm looking forward to the repairs being that it was not addressed the second time they came out. Hopefully three times will be a charm.

Tommie did an exceptional job fixing our AC when it wasn't cooling properly, and the level of service he provided went far beyond a standard repair. He was incredibly knowledgeable, worked hard to resolve the issue completely, and took the extra time to explain helpful tips on how to keep our system running smoothly and well-maintained. Tommie also reviewed previous work done on our system to identify and pointed out lingering issues, giving us complete peace of mind. To top it off, he offered ongoing support—letting us know we could reach out if we noticed any further quirks down the road. If you want a skilled, hardworking technician who truly cares about long-term reliability and great customer care, ask for Tommie!

Tommy was very courteous. I explained the problem the a/c was having, he thoroughly checked the system inside and outside. I had corrected the drainage problem but wanted to make sure and have everything checked anyway. He gave me tips on how to keep the drain from getting stopped up again. Tommy is very knowledgeable about a/c systems and explains things in layman's terms. I would recommend him to anyone. Best warranty technician I have used.

I went through Choice Home Warranty and they assigned 24 Seven A/C as the repair company. They were great and accommodating to my busy schedule. They installed a new condenser and evaporator coil. I have been having issues with my system all summer. I used two other vendors previously. Glad that 24 Seven finally was assigned and they fixed it. I also paid extra to upgrade my system from a 4-ton to a 5-ton Trane! Love it and the system is working perfect now.

Frequently Asked Questions (FAQ)

Because of the intense humidity and year-round usage in the Houston area, we recommend biannual maintenance—once in the spring for your AC and once in the fall for your heating system. Regular tune-ups help prevent unexpected breakdowns during summer days and keep your energy bills manageable.

 

Yes. We are a fully licensed and insured HVAC contractor in the state of Texas. Our License No: TACLA122806E ensures that all our work meets the strict safety and technical standards set by the Texas Department of Licensing and Regulation (TDLR).

 

In the extreme Houston heat, warm air usually points to one of three common issues: a clogged air filter restricting airflow, low refrigerant levels (possibly due to a leak), or a malfunctioning compressor. If your air isn’t cold, turn the unit off and call us immediately to prevent permanent damage to the motor.

 

The Department of Energy recommends setting your thermostat to $78^{\circ}F$ when you are home. However, to combat Houston’s high humidity, you may want to ensure your system is also in “Auto” mode rather than “On” to allow the moisture collected on the coils to drain properly between cycles.

 

While many units are rated for 15+ years, the heavy workload caused by the Texas climate often results in a lifespan of 10 to 12 years. Regular maintenance is the single best way to push your system toward that 15-year mark and avoid early replacement.

 

Absolutely. We understand that AC failure in the middle of a Houston July is a safety concern. 24SevenAC offers 24/7 emergency repair services throughout Katy, Fulshear, and the Greater Houston area.
