In Texas, HVAC contractors who install or service air conditioning equipment must be registered with the Texas Department of Licensing and Regulation (TDLR). Ask the contractor for their TDLR license or registration number and verify it on the TDLR website. Also confirm the technician(s) who will handle refrigerant have EPA Section 608 certification (a federal requirement). Request proof of general liability insurance and ask whether the company carries workers’ compensation or how employee injuries are covered—lack of coverage can expose homeowners to liability in some situations. Finally, check for any required local registrations or permitting requirements in the City of Houston and read online reviews and references.

Consider repair versus replacement based on system age, repair frequency, efficiency, and cost. Most central AC systems last roughly 10–15 years; if your unit is near or beyond that range and repairs are becoming frequent or costly, replacement is often more economical. Compare the cost of a repair to the remaining expected life and the energy savings of a new higher-SEER unit—if a single repair approaches 40–50% of replacement cost, replacement is usually the better choice. Also consider refrigerant type (older systems using R‑22 are more expensive to service), increased cooling demand in Houston’s hot, humid climate, and whether the system was properly sized and installed (a contractor should perform a load calculation). Ask contractors for written estimates that include efficiency ratings, expected energy savings, and projected payback.

A clear written estimate or contract should list the scope of work, specific equipment brand and model numbers, efficiency ratings (SEER/HSPF as applicable), itemized costs for equipment and labor, any required permits, and who obtains them, and a timeline for completion. It should state whether removal and disposal of old equipment is included, detail warranty information (manufacturer’s warranty and any installer warranty), payment schedule, and conditions for change orders. The contract should also describe any required inspections and final testing and include a contact for follow-up service. Before signing, verify that the contractor will obtain Houston permits and inspections and keep copies of permits and final inspection approvals.
