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.

This tells me these people are not very good at communication.
A: In 2026, a single-zone installation in Houston typically ranges from $3,500 to $6,000. Costs vary based on the unit’s SEER2 rating and the distance to the outdoor compressor. We offer 0% APR financing to make this upgrade affordable.
A: For specific rooms or additions, yes. They are more efficient because they eliminate “duct loss” (air leaking into the hot attic). For a whole 3,000 sq ft home, a central AC Installation is usually better, but mini splits are the best “supplemental” cooling.
A: Yes! Most systems we install are “Heat Pumps,” providing powerful heating even during Houston’s occasional freezes. If your unit stops heating, check our Furnace Repair or emergency heat pump services.
