Baker-Jones Co. Inc

In Texas, HVAC contractors and technicians are regulated by 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 ask for proof of general liability insurance and, if applicable, workers’ compensation coverage or a waiver; request an insurance certificate with policy dates and carrier information. Finally, check local records for any complaints, ask for references from recent Houston jobs, and confirm the contractor will pull required permits and arrange inspections for installation or major work.

Expect the contractor to perform a formal load calculation (Manual J) to size the equipment properly — oversizing can cause humidity and comfort problems in Houston’s climate. The written estimate should list equipment make/model, SEER efficiency rating, refrigerant type (note R‑22 is phased out and replacement costs are high), labor, expected timeline, and permit/inspection responsibilities. The scope should include evaluating and sealing ductwork, ensuring correct refrigerant charge and airflow, and verifying drainage and condensate handling. Ask about manufacturer and labor warranties (get details in writing) and confirm who will pull the city or county permits and schedule final inspections.

Because Houston has a long, hot, humid cooling season, schedule HVAC maintenance at least once a year for cooling (spring) and once for heating (fall) if you use heating; many homeowners choose biannual tune-ups. Typical maintenance tasks include changing or inspecting filters, cleaning condenser and evaporator coils, checking refrigerant levels and for leaks, inspecting and cleaning condensate drains, testing thermostat operation, tightening electrical connections, lubricating moving parts, and inspecting ductwork and airflow. Regular service improves efficiency, reduces breakdown risk during peak heat, and helps preserve warranty eligibility — keep service records and ask the contractor about maintenance plans and priority or emergency service options.
