Houston HVAC

Ask for the contractor’s Texas HVAC license number and verify it on the Texas Department of Licensing and Regulation (TDLR) website. Request proof of general liability insurance and ask whether they carry workers’ compensation or other coverage for their employees. Also check local requirements—some cities or counties require additional registration or permits—and ask for references or online reviews from recent Houston-area jobs.

A reputable contractor will perform a heat‑load calculation (commonly called a Manual J) that accounts for your home’s square footage, insulation, windows, orientation, occupancy and local climate conditions (Houston’s hot, humid summers are an important factor). They should also inspect ductwork and air distribution to avoid undersizing or oversizing. Properly sized equipment and well-designed airflow are important in Houston to control temperature and humidity; oversizing can cause short cycling and poor humidity control.

Expect two types of warranties: the manufacturer’s parts and compressor warranty (terms vary by brand) and a contractor-provided labor or workmanship warranty—get both in writing. Annual preventive maintenance (at least once before cooling season) is recommended in Houston’s climate to maintain efficiency and reliability. Most replacements or major installations require local permits and inspections—check with the City of Houston or your county building department—and a reputable contractor should handle permit pulls. Typical straight-forward replacements often take a day or two; more complex jobs (ductwork, electrical upgrades, or permitting delays) take longer. Always get a written estimate that lists scope, equipment model/efficiency, timelines and warranty details.
