AC Installation in Calhoun, GA, Done by the Numbers

The Problem

Why most AC installs fail before the truck leaves

Here's the uncomfortable truth in this trade: the most common cause of a brand-new system underperforming isn't the equipment brand. It's a bad install. An air conditioner is sized, charged, and ducted to move a specific amount of heat out of a specific house. Skip the math and you get a unit that's wrong for the home from the first day, no matter how good the nameplate.

The two classic mistakes are oversizing and ignoring the ducts. An oversized AC blasts the thermostat satisfied in a few minutes, shuts off, and never runs long enough to pull humidity out of the air. So a Calhoun summer leaves you cold, damp, and reaching for the thermostat. And if the ductwork leaks into a hot attic or is too small to carry the airflow, even a perfectly sized unit starves and underperforms.

Our Process

How Anderson sizes and installs a system

• Manual J load calculation. We calculate your home's real heat gain (square footage, insulation, windows, orientation, air leakage, ceiling height) instead of guessing by the ton.
• We measure the building. Most shops can't. We run a blower door to see how much outside air leaks in and a duct blaster to see how much conditioned air leaks out. That tells us whether the ducts need sealing or resizing before the new unit goes in.
• Right-sized, matched equipment. Outdoor condenser and indoor coil chosen as a matched pair at their rated efficiency, no mismatched parts that quietly waste the efficiency you paid for.
• A real commissioning. Deep vacuum on the lines, refrigerant charged to the manufacturer's spec by measurement, duct static pressure and airflow checked, and the temperature split verified before we call it done.

Local Conditions

Why this matters more in a Calhoun summer

Long stretches of humid, 90-degree afternoons punish a system that's mis-sized or ducted poorly, whether the home is older with retrofitted ducts or newly built. Getting the install right the first time is the single biggest thing you can do for comfort and your power bill.

Our Story

Founder John Anderson learned this the hard way

Customers kept telling John their new units were in but the power bill was still sky-high. So he went deeper than the box outside, into insulation, air sealing, and the building science of the whole home. That's why Anderson sizes from a load calculation and measures the house instead of selling tonnage. We'd rather install the right system once than the biggest one twice.
