Home AC and Heating System Replacement in Austin, TX
Licensed Texas Contractor TACLA00116720C · 512-992-5537
Replacing a system is the largest single repair most homes ever face, and it is the one most often sold on pressure rather than measurement. Setpoint Services has spent years sizing and installing equipment for Austin-area businesses, where an undersized system shows up on the power bill every month. We bring the same approach to homes.
When Replacement Makes Sense
Plenty of systems that get quoted for replacement should be repaired instead. These are the situations where replacing genuinely is the better spend.
- A failed compressor or heat exchanger on equipment that is already well into its service life
- Repair costs approaching a meaningful share of what a new system would cost
- Repeated failures across a single season — a pattern rather than one bad part
- A system that cannot keep up on the hottest days no matter what is done to it
- Equipment using a refrigerant that is being phased out, where charge is getting expensive
- A unit that was undersized or oversized when it went in and has never worked properly
Sizing Comes Before Anything Else
The most common mistake in residential replacement is matching the tonnage of whatever is already there. If the old unit was wrong, the new one inherits the problem. Worse, oversizing is not the safe choice people assume — a system that is too large cools the air quickly, satisfies the thermostat, and shuts off before it has pulled the humidity out. The house ends up cold and clammy, and the equipment wears out faster from short cycling.
We size against the house: square footage, insulation, window exposure, ceiling height, and the ductwork that has to carry the air. In Austin, humidity control matters nearly as much as temperature, and that is a sizing decision more than an equipment one.

What Gets Replaced
A residential system is a matched pair — the condenser outside and the coil and air handler or furnace inside. Replacing only the outdoor unit and leaving an older indoor coil in place is a common shortcut, and it usually costs you the efficiency rating you paid for. We will tell you when a partial replacement is genuinely fine and when it is not.
- Outdoor condenser or heat pump
- Indoor coil, air handler, or furnace matched to the outdoor unit
- Refrigerant lines — evaluated, flushed, or replaced depending on the refrigerant change
- Thermostat compatible with the new equipment’s staging
- Electrical, drain, and pad or stand work to bring the installation up to current standards
