Atlas AC Repair LLC

In Texas, HVAC contractors who install or service air conditioning and refrigeration systems must be licensed through the Texas Department of Licensing and Regulation (TDLR). Ask the contractor for their TDLR license number and verify it on the TDLR website. Also ask for proof of general liability insurance and any workers’ compensation coverage they carry (Texas does not require employers to carry workers’ comp, but many reputable contractors do). Verify local requirements as well: the City of Austin requires permits for most HVAC installs and replacements, so confirm the contractor pulls required permits and follows Austin Energy and building-code rules. Always get written references, a detailed estimate, and contact information before work begins.

Ask the contractor to perform a proper load calculation (Manual J) for your home rather than relying on unit tonnage rules of thumb; proper sizing avoids short-cycling and comfort problems in Austin’s hot, humid summers. Request details about the complete system (indoor coil, condenser, matched components) and the unit’s SEER (Seasonal Energy Efficiency Ratio) rating—higher SEER typically means lower cooling costs in a warm climate, but there are diminishing returns. Ask about variable-speed or two-stage compressors for better humidity control, current refrigerant type (new equipment uses R‑410A or approved alternatives; R‑22 is phased out), and whether ductwork needs sealing or adjustment. Also check for available utility rebates from Austin Energy or other local programs that can offset high-efficiency upgrades.

Expect two separate warranty types: the manufacturer’s warranty for parts and compressors (length and coverage vary by brand and model) and a contractor labor or workmanship warranty. Get both warranties in writing, including what is covered and how to file a claim. Ask about recommended maintenance (most contractors advise a biannual tune-up: spring for cooling and fall for heating) and whether they offer service or maintenance plans with prioritized service and discounts on repairs. Confirm emergency or after-hours response policies and typical response times. Also require a written contract/estimate that lists equipment model numbers, projected timeline, who pulls permits, cleanup responsibilities, and payment terms before work starts.
