AC Installation in Chattanooga & North Georgia
The Right System, Installed the Right Way
Replacing an air conditioner is a major investment, and the installation matters as much as the equipment. A unit that's oversized cools in short bursts and leaves the house humid; one that's undersized runs all day and still can't keep up during a Chattanooga heat wave.
Metro sizes every new system to your home, considering square footage, insulation, windows, sun exposure and ductwork rather than simply matching the old unit. We install matched indoor and outdoor components, check refrigerant line sets and electrical, and seal connections so the system performs to its rating.
You'll see clear good, better and best options with an all-in upfront price, plus financing for qualified customers. We remove your old equipment and walk you through the new thermostat before we leave.

Signs You Need AC Installation
Your AC Is 12 to 15+ Years Old
Systems reaching 12 to 15 years old are less efficient and more prone to major failures.
Facing an Expensive Repair
When a repair costs a large share of a new system on an aging unit, replacement is usually the better value.
Uses Older, Phased-Out Refrigerant
Older systems may use phased-out refrigerant that's increasingly expensive to service.
Repeated Breakdowns
Multiple service calls in a few seasons are a sign the system is wearing out.
Summer Bills Keep Climbing
Rising bills with the same usage point to declining efficiency.
Home Never Feels Comfortable
Persistent humidity, hot rooms or a system that never catches up may mean the equipment is the wrong size.

Transparent, Upfront Pricing
What Affects the Cost of AC Installation?
A new air conditioning system's price depends on the size your home needs, the efficiency rating you choose, whether you're replacing just the outdoor unit or a matched indoor and outdoor system, and the condition of your ductwork, electrical and refrigerant lines. Single-stage, two-stage and variable-speed systems also differ in cost and comfort.
We calculate the right size for your home rather than matching the old unit, show you good, better and best options, and give you an all-in price. Financing is available for qualified customers.
You always get the price before any work begins. Financing is available for qualified customers on larger jobs.
Expert Tip From Metro's Master-Certified Team
Ask How the System Was Sized
When comparing AC quotes, ask each contractor how they sized the system. If the answer is simply matching the old unit's tonnage, that's a red flag. Homes change over time with new windows, insulation and additions, and the right size today may be different.

Frequently Asked Questions

(423) 855-0967How long does a central AC system last?
Many central AC systems last around 12 to 15 years with regular maintenance. Heavy use, coastal or dusty conditions and skipped maintenance shorten that.
Why does sizing matter so much?
Bigger isn't better. An oversized AC cools quickly but shuts off before removing humidity, leaving the house clammy. We size the system to your home's actual load.
Do I need to replace the indoor unit too?
Matching the indoor coil and outdoor unit ensures rated efficiency and protects warranties. Replacing only one half often reduces performance.
How long does installation take?
Most replacements are completed in a day once equipment is on hand.
Is a higher-efficiency system worth it?
Higher efficiency systems cost more up front but use less electricity. We'll help you weigh the upfront cost against expected savings for your home.
Do you offer financing?
Yes. Financing is available for qualified customers on new systems.
