Compare the diagnosis, system condition, comfort problems, and the scope of a written quote before deciding what comes next.

Compare the diagnosed repair, the system’s condition and service history, its comfort performance, and a written replacement proposal. Frequent repairs and rising energy use can make replacement worth evaluating. An isolated repair on otherwise serviceable equipment may be a different decision. Ask the contractor to explain both options instead of relying on age or a simple rule alone.
AC Answer 18
No. ENERGY STAR identifies an air conditioner older than ten years as a reason to consider replacement, not a mandatory retirement date. Have its condition and performance evaluated alongside repair history and energy use. The decision should reflect your equipment and home, with clear repair and replacement options rather than an age-only recommendation.
AC Answer 19
A contractor should calculate your home’s cooling needs from its actual characteristics, then select suitable equipment. Square footage or the old unit’s size alone is not enough. Oversizing can cause frequent cycling and comfort problems. Ask to review the sizing basis and how the installation will address airflow, refrigerant charge, and ducts.
AC Answer 20
No. EPA says existing systems can continue to be maintained and repaired through their useful life. Requirements for new equipment differ from repairs to an existing system. Before approving work, confirm your refrigerant type and whether the proposal is a component repair or a new system. Ask the contractor to explain the applicable requirements in writing.

There is no single lifespan that predicts when your coastal Texas AC will fail. Maintenance, installation quality, repair history, and exposure all matter. An older system with repeated failures deserves a replacement comparison, while visible corrosion deserves inspection. Use a condition assessment to plan ahead rather than treating a general age estimate as a guarantee.
AC Answer 38
Compare the equipment models, installation scope, sizing basis, efficiency information, warranty documents, and total written cost. Ask whether duct work, permits, and removal of old equipment are included where applicable. TDLR recommends obtaining more than one bid. A lower total may represent different work, so resolve missing details before choosing a proposal.
