AC & HVAC Replacement in Katy, TX

Houston-area planning ranges for 2026 run from about $5,500 for basic scopes to $18,000 or more for high-efficiency or larger projects. Capacity, matched indoor equipment, ductwork, electrical work, access, controls, refrigerant, and commissioning all affect the actual estimate.

An isolated failure on an otherwise reliable system may support repair. Repeated repairs, a major compressor or coil failure, poor comfort, aging equipment, or an unfavorable combination of repair cost and future risk can make replacement worth comparing. There is no universal percentage rule that decides every home.

Timing depends on the equipment, scope, access, electrical or duct changes, inspection requirements, and conditions found during installation. APCA confirms the expected schedule for the specific project instead of promising every replacement can be completed in one day.

Not automatically. The answer depends on the furnace condition, age, blower capability, indoor coil, controls, efficiency goals, and compatibility with the proposed outdoor equipment. Compare quote scopes carefully because a condenser-only change and a complete matched system are different projects.

Square footage and old tonnage are useful inputs, but they are not enough by themselves. Insulation, windows, orientation, air leakage, duct conditions, occupancy, and changes to the home affect the load. When a formal residential load calculation is required, Manual J is the recognized residential sizing method.

SEER2 is the seasonal cooling output divided by the electrical energy used under the current federal test procedure. It helps compare rated cooling efficiency, but comfort, sizing, equipment matching, controls, ductwork, and installation quality also matter.

Yes. Existing R-410A systems are not automatically obsolete or illegal. EPA rules allow components to remain available for servicing existing systems, subject to equipment compatibility and parts availability.

Many current residential systems use lower-GWP refrigerants such as R-32 or R-454B, depending on the manufacturer and matched equipment. EPA's 2026 rule also allows qualifying pre-2025 higher-GWP inventory to continue being installed while supplies last. The quoted equipment and refrigerant should be confirmed before purchase.

Heat pumps can provide both cooling and heating and are one system type to compare for the Houston climate. The electrical service, backup-heat strategy, indoor equipment, controls, home load, and comfort goals determine whether a heat pump is a suitable option.

Available brands and equipment families can change with distributor inventory, system requirements, and matched-system certification. APCA discusses currently available options for your scope rather than promising every brand or model on every project.
