AC Replacement in Marietta, GA

AC replacement in Marietta starts with a look at the whole system, not just the outdoor unit. We measure the house, check duct sizing, look at return air and the state of the crawlspace lines, then size the equipment to what your rooms actually need. Matching a new condenser to an old indoor coil causes trouble later, so we talk through both. Old refrigerant gets recovered properly and the pad and electrical get brought up to date. Call us or send the quote form to set up a walkthrough.

Why Marietta homes end up needing this

The upstairs is ten degrees hotter than the downstairs Duct design and airflow distribution, zoning or mini-split candidate
My repair quote costs more than the unit is worth Compressor or coil failure on an older system, replacement decision
The addition and the bonus room never had ducts No supply to the space, ductless mini-split application

What a replacement day actually involves

We start by protecting floors and clearing a path to the indoor coil or air handler. The old refrigerant is recovered properly, the outdoor unit comes off its pad, and the indoor section comes out. Then we set the new equipment, run new line set or flush the existing lines, make the electrical and drain connections, pull a vacuum, weigh in the charge, and set up the thermostat. Most single-system changeouts finish in a day. Bigger jobs with duct or crawlspace work can run into a second day.

What we check and install

Before we quote anything we look at the whole system, not just the box outside. We check duct sizing and leakage, the condensate path, the pad and clearance around the outdoor unit, the disconnect and breaker, and the return air. Red clay crawlspaces are hard on flex duct and drain lines, so we get under there and look. On installation we replace the line set filter drier, fit a new thermostat if the old one cannot run the equipment, and seal the plenum connections instead of reusing torn tape.

AC Replacement in Marietta — quick answers

Do I have to replace the indoor unit too?

Almost always, yes. New outdoor units are matched to a specific indoor coil, and mixing old with new causes capacity and drainage problems. We will explain the matching before you decide anything.

Can you reuse my existing ductwork?

Often we can, if the sizing is right and the duct is intact. We inspect it first. Torn crawlspace flex or badly undersized returns get repaired or replaced, otherwise the new system underperforms.

How soon can you get to my Marietta home?

Call us and we will give you a real window for the same or next day in most cases, depending on how the day is running. Tell us whether you have no cooling, no heat, or a system that runs but will not hold temperature, because that changes how we prioritize the call. If you have already checked the thermostat batteries and the breaker, mention that too. It saves time once we are in the driveway.

How it works

Step 1
Tell us the symptom
Call or fill in the quote form and describe what you hear, smell or feel. Warm air, short cycling, a breaker that keeps tripping. That gives us a head start on the likely cause.
Step 2
We diagnose on site
A technician checks the thermostat, airflow, electrical connections, refrigerant performance and the outdoor unit. We work the crawlspace and the attic too, because ductwork and drainage cause more trouble than people expect.
Step 3
You decide, then we fix it
We explain what failed, what it takes to repair it, and what we would watch next season. No work starts until you say go. Most repairs finish the same visit when parts are on the truck.

Why homeowners call us

Mixed heating is normal to usHeat pumps, propane furnaces and dual-fuel setups all behave differently in cold weather. We know how a heat pump should sound in the thirties and when the backup heat is doing too much of the work.
We go under the houseRed clay crawlspaces hide crushed ducts, sweating lines and standing water. Comfort problems often start down there, not at the unit, so we look before we start replacing parts you may not need.
Plain explanationsYou get told what broke and why, in words that make sense. If a repair is a short-term patch on an aging system, we say that out loud so you can plan instead of guessing.
One crew, six statesWe serve homeowners across Alabama, Georgia, Kentucky, North Carolina, South Carolina and Tennessee. Same approach in every one: show up, diagnose properly, repair what needs repairing, leave the space clean.
