Ask the contractor for their Texas license or registration number and verify it on the Texas Department of Licensing and Regulation (TDLR) website. Make sure their technicians who handle refrigerant are EPA Section 608 certified. Request a Certificate of Insurance showing general liability coverage and, if applicable, workers' compensation—do not rely solely on verbal assurances. Also confirm who will pull required permits for installations or major repairs in Houston; a reputable contractor will obtain permits and schedule inspections as required by the city.

Price depends on system size and type, energy-efficiency rating (SEER), brand, and whether you need modifications to ductwork or electrical service. Proper sizing with a Manual J load calculation is essential—oversized or undersized equipment reduces comfort and efficiency. Other factors include labor, required permits, disposal of the old unit, and refrigerant issues (older systems using R‑22 can be much more expensive to recharge). Get at least two written, itemized estimates that include equipment model, estimated SEER, scope of work, timeline, permit responsibility, and warranty information; also check for local utility rebates or financing options.

Yes—regular maintenance improves comfort, efficiency, and equipment life, especially in Houston’s hot, humid climate. Typical maintenance twice a year (spring for cooling, fall for heat or heat-pump checks) should include changing/checking filters, cleaning coils and condensate drain, checking refrigerant charge and electrical connections, inspecting and sealing ductwork, testing the thermostat, and looking for signs of moisture, mold or corrosion. Keep records of maintenance visits—many manufacturers require regular service to maintain warranties—and consider a seasonal tune-up plan that offers priority service and diagnostic checks.
