Efficient AC, Electric & Plumbing

Yes. In Texas air conditioning and refrigeration contractors must be registered with the Texas Department of Licensing and Regulation (TDLR), and technicians who work with refrigerants are required to hold EPA Section 608 certification. Local requirements also apply: the City of Austin requires permits for most HVAC installations and replacements, and many homeowners prefer contractors who carry general liability and workers’ compensation insurance. Always ask a contractor for their TDLR registration number, proof of EPA 608 certification, insurance, and any local permit history before hiring.

Sizing should be based on a professional load calculation (Manual J), not a rule-of-thumb or simply matching the old unit. A proper calculation accounts for square footage, insulation, windows, orientation, duct losses, and occupancy — important in Austin’s hot, humid climate. Efficiency is shown by SEER (Seasonal Energy Efficiency Ratio); higher SEER units use less energy but cost more upfront. A qualified contractor should perform a Manual J load calc, recommend equipment and ductwork corrections (Manual D), explain expected energy use and payback, and help identify available local or utility rebates (for example, from Austin Energy) for high-efficiency systems.

Have a professional tune-up at least once a year (schedule before the cooling season in Austin). Routine tasks include checking refrigerant charge and pressures, cleaning coils, inspecting electrical components, calibrating the thermostat, and checking airflow and duct connections. Homeowners should change or inspect filters every 1–3 months depending on use and filter type, keep the outdoor unit clear of debris, and seal/insulate ducts when needed. Regular maintenance extends equipment life, improves efficiency, and may be required to maintain manufacturer warranties; ask for a written maintenance checklist and keep records of service.
