AC Installation
AC installation in Chattanooga, sized to your house — not the old box.
Most replacement systems are sized by matching the tonnage of the unit being removed. If that unit was wrong, the new one inherits the mistake. We start with a load calculation and finish with a commissioning report.
Why sizing matters more than brand
An oversized system is the most common — and most expensive — mistake in residential air conditioning. It cools the air fast, shuts off before it pulls the humidity out, and leaves you with a clammy house, short-cycling equipment, and a compressor that wears out early. Bigger is not better; correct is better.
The only way to size correctly is to calculate the home's actual heating and cooling load. The equipment that gets installed should answer that number, not the label on the box that's coming out.
Our installation process
Every installation starts with a Manual J load calculation for your specific house — its windows, insulation, orientation, and air leakage. Manual S selects equipment matched to that load. Manual D sizes and designs the duct system so the equipment can actually deliver what it's rated for. Each load calculation gets an independent engineering review before the quote.
Then we install, and we commission. Verification against ACCA Standard 5 — measured airflow, static pressure, temperature split, and refrigerant charge — confirms the finished system performs the way it was designed to, with the numbers documented before we invoice.
Ductwork is half the system
New equipment bolted onto an undersized, leaky duct system will disappoint you no matter how efficient the box is rated. We measure static pressure and test for duct leakage, and we correct the duct problems that would otherwise rob the new system of performance — instead of pretending the equipment alone will fix a comfort complaint.
Replace or keep repairing?
Replacement isn't always the answer, and we won't push it when a documented repair makes more sense. When the numbers do favor a new system, you'll see the load calculation, the equipment selection, and the duct plan — a written, measured case for the recommendation, not a high-pressure pitch.
Common questions
AC Installation questions, answered straight.
- How do you size a new system?
- With a Manual J load calculation for your specific house — windows, insulation, orientation, air leakage. We size the equipment to that number, not to the unit being removed. Oversizing is the most common and most expensive mistake in residential air conditioning.
- Why does the ductwork matter if I'm buying new equipment?
- New equipment on an undersized, leaky duct system disappoints no matter how efficient it's rated. We measure static pressure and test for duct leakage, and we correct what would otherwise rob the new system of performance.
- What is commissioning, and why does it matter?
- After install we verify the system against ACCA Standard 5 — measured airflow, static pressure, temperature split, and refrigerant charge — and document it before we invoice. It confirms the system performs the way it was designed to.
