If your AC is over 10 years old, costing more to repair than it's worth, or just can't keep up with a Carolina summer anymore, it's probably time for a replacement. Total Plumbing Pros installs central air conditioning systems across Mooresville, Charlotte, Lake Norman, and surrounding NC and SC communities — with proper Manual J sizing, brand options that fit your budget, and financing for every project.
We install Carrier, Trane, Lennox, Goodman, Rheem, American Standard, and other major brands, in efficiency tiers from solid 14 SEER2 single-stage systems to high-efficiency 18+ SEER2 variable-speed inverter units. Every install includes the in-home assessment, the manufacturer warranty, removal of the old equipment, and a workmanship guarantee from us.
Signs You Need AC Installation & Replacement
OVER 10–12 YEARS OLD
Central ACs in our climate typically last 12–18 years. Once a system passes 10, repair-vs-replace math starts to favor replacement — especially for older R-22 (Freon) units.
REPAIR COSTS APPROACHING HALF OF REPLACEMENT
A common rule of thumb: if a single repair is more than 50% of the cost of a new system, replacement is usually the better long-term value.
RISING UTILITY BILLS
If your summer power bills have crept up despite normal usage, your AC's efficiency is dropping. A new high-SEER system can cut cooling costs significantly.
UNEVEN COOLING OR CAN'T KEEP UP
Rooms that won't cool, long run times, and a system that just can't hold the setpoint on a hot afternoon all signal that the unit is undersized, failing, or both.
What's Included
- Free in-home assessment with proper Manual J load sizing — not rule-of-thumb tonnage

Typical Pricing
$5,500 – $12,000
Most central AC replacements in the Carolinas fall in this range, including a new condenser, coil/air handler, refrigerant line work, and removal of the old equipment. Larger homes, high-SEER variable-speed systems, or significant duct modifications add to the total. Financing is available on every install.
Our Process

Free in-home assessment

- 3
Install day
The old equipment is removed, the new condenser, coil, and any necessary line/duct work installed to manufacturer spec, and the system fully commissioned.
- 4
Commissioning + thermostat pairing
Refrigerant charged to spec, airflow verified, and the thermostat (or new smart thermostat) is set up and tested.
