AC & Heating Contractors in Texas

AC & Heating in Texas: what to know

Texas summers are long and hot statewide, so a home's HVAC system runs hard for much of the year and cooling capacity does most of the work — but occasional hard freezes (like the February 2021 storm) mean the heating side has to be ready too, which is why many Texas homeowners replace as a matched system or move to a heat pump that does both. Air conditioning and refrigeration work is regulated in Texas: the contractor must hold a TDLR Air Conditioning & Refrigeration (ACR) license, Class A or B. Correct sizing — a Manual J load calculation rather than a rule of thumb — matters more here than in milder climates, because an oversized or undersized system fights a long cooling season and handles humidity poorly. New equipment is also rated on the current SEER2 (cooling) and HSPF2 (heat-pump heating) standards.

What affects the cost

• System type: a matched AC + furnace “split system” versus a heat pump that handles both heating and cooling — each is priced and installed differently.
• Sizing from a Manual J load calculation (square footage, insulation, windows, ceiling height, sun exposure) — the right tonnage drives both the equipment and long-term comfort.
• Efficiency tier: higher SEER2 (cooling) and HSPF2 (heat-pump heating) equipment costs more up front but uses less energy over the long Texas cooling season.
• Whether it's a full matched-system replacement or a single component — pairing a new outdoor unit with an old indoor coil can hurt efficiency and void warranty coverage.
• Ductwork condition and any sealing, resizing, or replacement needed so the new system's airflow is correct.
• Line-set, thermostat, electrical/breaker changes, permits, and inspection required to bring the install up to current code.

How to choose a AC & Heating contractor

• Verify the contractor holds a current TDLR Air Conditioning & Refrigeration (ACR) license, Class A or B — you can look the license up on the TDLR website.
• Insist on a Manual J load calculation for a replacement, not a “same size as the old one” guess, so the system is matched to the home.
• Get an itemized written proposal listing equipment model numbers and the SEER2/HSPF2 ratings, so you're comparing bids on the same equipment.
• Ask that the outdoor unit and the indoor air handler/furnace be replaced as one matched system, and get both the manufacturer's equipment warranty and the contractor's labor warranty in writing.
• Confirm they pull the required permit and schedule the inspection where the city requires one.
