A central AC system typically lasts 15 to 20 years with regular maintenance. In Austin’s heavy-use climate, that lifespan often falls on the shorter end. Knowing when to replace saves you from repeated repairs on a system that is past its useful life.

Frequent repairs over the past two years signal the system is reaching its end. If you are calling for service more than once a season, the equipment is wearing out faster than parts can fix it.

Rooms that stay warm while others cool point to a system that can no longer handle the full load. Rising energy bills with no change in usage often mean the compressor is losing efficiency.

Refrigerant type matters too. Older systems using R-22 are no longer supported. Replacement parts for these units are scarce and becoming harder to source. Homes in Travis Heights and Bouldin Creek built in the 1950s through 1970s often still run second-generation systems well past their expected service life.

System size is measured in tons. One ton removes 12,000 BTUs of heat per hour. Picking the wrong size creates problems that last the entire life of the equipment.

A 3-ton unit is not automatically right for 1,500 square feet. Insulation quality, window count, sun exposure, and ceiling height all change the calculation. A home with large west-facing windows needs more cooling capacity than one with heavy tree cover on the same street.

A Manual J load calculation accounts for every factor that affects your home’s cooling demand. This includes square footage, ceiling height, window orientation, insulation rating, and local climate data for the Austin area.

An oversized system short cycles, wastes energy, and leaves your home humid. An undersized system runs nonstop and cannot reach the set temperature on 100°F+ days. Downtown Austin homes range from 900 square foot condos along South Congress to 3,000+ square foot properties in Tarrytown. Each needs a different tonnage based on a professional calculation, not a rule of thumb.

A few steps before the crew arrives help the installation go smoothly. Preparation reduces disruption to your household and keeps the project on schedule.

Clear a path from your front door to the indoor air handler and outdoor condenser location. Move furniture, boxes, and stored items away from the indoor unit and ductwork access points. Most Downtown Austin homes run ductwork through the attic, so make sure the attic access is clear as well.

Secure pets in a separate room during the installation. The crew will move between indoor and outdoor work areas throughout the day. Expect a standard replacement to take one full day.

Spring and early fall are the best seasons to schedule installation in Austin. Demand drops and lead times shorten between October and March. Booking outside of peak summer gives you shorter wait times and cooler working conditions for the installation crew.
