Service from Tommy was outstanding and quickPosted on Google Maziyar SamadzadehTrustindex verifies that the original source of the review is Google. I cannot recommend 24/7 HVAC based on my experience. They were assigned by my home warranty company to replace the condenser fan motor on my AC unit. During their testing—before the technician even left—the outdoor unit began making excessive noise, and the fan was visibly wobbling. I immediately pointed this out to the technician. He attempted several adjustments but was unable to eliminate the noise or wobbling, yet the repair was still considered complete. The installation also raised several concerns. A generic aftermarket fan motor was installed instead of the original OEM motor, modifications were made that left wiring exposed, and components were not reassembled correctly. I reported the issue to both 24/7 and my home warranty company the same day, but no corrective action was taken. A second technician from 24/7 later inspected the unit and agreed that the original repair had not been performed properly. Before the issue could be corrected, the fan blade failed, leaving my AC completely inoperable. What is most frustrating is that the current explanation focuses on the broken fan blade, even though the excessive noise and fan wobbling were present immediately during the repair while the technician was still on site. Those problems were reported before the blade ever failed. In my opinion, the original repair should have been corrected at that point instead of allowing the system to continue operating with an obvious problem. As a result, my family has been without air conditioning during the Texas summer while my warranty claim has remained unresolved for nearly two months. I have photos, videos, repair records, and correspondence documenting the entire sequence of events.Posted on Google Cynthia KnightTrustindex verifies that the original source of the review is Google. 24 Seven AC arrived early and installed my new AC condenser very quickly and professionally. They did a perfect job! I would recommend this company highly to anyone looking for AC services.Posted on Google David BerrierTrustindex verifies that the original source of the review is Google. 24-Seven recently replaced my air conditioning condensor and coil. My air conditioning is now working GREAT!Posted on Google Nishchay ChadhaTrustindex verifies that the original source of the review is Google. Amazing experience, great service. Tommie was super helpful. I highly recommend himPosted on Google lxxney igTrustindex verifies that the original source of the review is Google. Not sure why advertise and not pick up calls. This tells me these people are not very good at communication.
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.
