Replacing your air conditioning system is one of the most significant home investments you will make. In Greenville's hot, humid climate, getting the sizing, efficiency, and installation right is more important here than in most of the country. An improperly sized or poorly installed system will underperform, waste energy, and fail prematurely.
We start every AC replacement with a Manual J load calculation. This engineering standard accounts for your home's square footage, insulation R-values, window area and glazing type, ceiling height, building orientation, number of occupants, and Greenville's specific climate data. The result is a precise cooling load in BTUs that determines the correct system size. We never use rules of thumb or simply match the old system's tonnage.
Proper sizing is critical in Greenville's humidity. An oversized AC will cool the air temperature quickly but shut off before removing adequate moisture, leaving your home feeling clammy at 72 degrees. This short-cycling also increases wear on the compressor and other components. An undersized system runs constantly without reaching the setpoint, consuming excess energy and struggling on the hottest days.
We install high-efficiency air conditioning systems from trusted manufacturers in efficiency ratings from 14 SEER (the current federal minimum) to 22+ SEER. The higher the SEER rating, the less electricity the system uses per unit of cooling. For Greenville's long cooling season (typically May through October), a higher-SEER system pays back its additional upfront cost faster than in milder climates.
Every installation includes professional removal and disposal of your old system, proper refrigerant charging to manufacturer specifications (verified with subcooling and superheat measurements), thorough ductwork inspection for leaks, new thermostat setup or smart thermostat integration, and a comprehensive system test including airflow measurement at every register. We do not cut corners.
Financing is available with no surcharges. We offer flexible payment plans that make a new high-efficiency AC system affordable. Many customers find that the monthly energy savings from a new system offset a significant portion of their financing payment, especially when replacing an older, low-efficiency unit.
Signs You Need AC Installation & Replacement
System Is 15+ Years Old
Most AC systems last 15-20 years. If yours is in this range, it's using older, less efficient technology and likely approaching end of life. Planning ahead avoids an emergency replacement in the middle of summer.
Frequent Expensive Repairs
If you're calling for AC repair multiple times per year, those costs add up quickly. A new system eliminates repair bills and comes with manufacturer warranty protection.
Rising Energy Bills
Older AC systems lose efficiency over time. If your energy bills keep climbing despite regular maintenance, a new high-efficiency system can significantly reduce your monthly costs.
Uses R-22 Refrigerant
R-22 (Freon) has been phased out and is now extremely expensive. If your system uses R-22, replacing it with a modern system using R-410A or R-454B saves money long-term.
Uneven Cooling Throughout Home
Hot spots, rooms that won't cool, or large temperature differences between floors often indicate your current system is improperly sized or failing.
Excessive Noise
A properly functioning AC should run relatively quietly. Increasing noise levels typically indicate worn components that may not be worth repairing in an older unit.

What We Offer
What it costs
A new central air conditioner is $4,000 to $8,000 installed. A full heating and cooling replacement is $8,000 to $15,000. A 5-ton or 19 SEER2 variable-speed system runs higher, typically into the high teens. Your price depends on system size, efficiency tier, and the condition of your existing duct. Estimates on replacements are free.
These are our own prices, not a national average. They are typical, not caps: size, efficiency tier, and access move the number. Your flat-rate quote comes before any work starts, and estimates on replacements are free.
