We replaced both systems in our Skybrook house. The advisor measured every room and actually recommended a smaller upstairs unit than we had. He was right. The bonus room is finally comfortable and our July bill dropped noticeably. Install crew was tidy and done in a day and a half.
A new air conditioner, sized right
A new air conditioner should keep your house cool and dry for the next 15 years. We measure your home room by room, size the system for Charlotte humidity, and back every install with a 10-year parts and labor warranty.

Many Charlotte homes have systems that are too big. An oversized air conditioner cools the air fast and shuts off before it has time to pull moisture out, so the house feels cold and clammy at the same time. Mold on vents and musty closets are common signs.
We run a full load calculation on every replacement. That means measuring windows, insulation, attic conditions and which way the house faces. Sometimes the right answer is a smaller system than the one you have now, with a variable-speed blower that runs longer at low speed to dry the air.
Efficiency ratings in plain language
New systems are rated in SEER2, which measures cooling efficiency under realistic conditions. Current minimums in the Southeast are around 14.3 SEER2 for split systems. Higher ratings cost more upfront and save more on power bills, and the payoff is stronger here because our cooling season is so long.
For most Charlotte homes, a mid-range two-stage system hits the sweet spot of comfort, humidity control and cost. Variable-speed systems are quieter and best at moisture removal. Federal tax credits and Duke Energy rebates may apply to higher-efficiency equipment, so check current eligibility before you decide.
What a Calloway install looks like
A typical replacement takes one day. Our install crew protects your floors, removes the old equipment and refrigerant safely, and sets the new outdoor unit on a level pad. We replace the refrigerant line set when the old one is undersized or damaged, and we add a float switch and a secondary drain pan where needed.
Before we leave, we test airflow and refrigerant charge, show you the thermostat, and register your warranty. A lead installer comes back within 30 days for a follow-up check, and our 1-year comfort promise means that if a room still is not right, we make it right.

AC replacement, five stars.
Renata came out herself to walk us through three options for our 22-year-old system. No pressure at all. We chose the two-stage option and used the monthly payment plan. The house is quieter and far less sticky than before. The 30-day follow-up visit was a nice touch.
Original builder system in our Kingsley house finally gave out after 16 years. They handled the York County permit and inspection, installed in one day and cleaned up like they were never here. Chris even called the next week to check in.
Good questions.
Still wondering? Call (704) 555-0164, a real person answers.
How much does a new AC cost in Charlotte?
A typical new central air conditioner in Charlotte, installed with a matching indoor coil, runs about $6,500 to $12,500 in 2026. Price depends on size, efficiency, whether the line set and pad need replacing, and how easy the equipment is to reach. We give you a flat quote in writing before anything is scheduled.
Do I need to replace my furnace at the same time?
Not always. If your furnace is under 10 years old and its blower is in good shape, we can often replace only the outdoor unit and indoor coil. If the furnace is older, replacing both together usually saves labor costs and gives you a matched system with better efficiency and a single warranty.
Do you offer financing?
Yes. We offer monthly payment options on new systems, subject to credit approval. Your comfort advisor can show you the monthly cost next to the full price for each option, and applying takes a few minutes. There is never any pressure to finance, and paying upfront is always an option.
How long does installation take?
Most replacements take one day. If we are also replacing ductwork, moving equipment or adding a new system in an attic, it can take two days. We will tell you the timeline in your quote, and we never leave you without cooling overnight in summer without offering portable units.
