What Our Customers Are Saying
EXCELLENT Based on 424 reviews Posted on Google Tamara ManuelTrustindex verifies that the original source of the review is Google. They came out stated they fixed my unit said I had to much Freon. Said my stack drain was clogged that I needed to call a plumber, called the plumber the plumber stated nothing was clogged. Have been calling them back and texting for 2 days no response, can’t leave a message from the number left on the card nor the website phone number. So unprofessional and my unit is still not working in this hot humid summer. Next will be to contact BBB and my warranty company that sent them.Posted on Google Bill PiggTrustindex verifies that the original source of the review is Google.

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.
