AC Installation in Kennesaw, GA — Book a Visit Today

When repairs start stacking up on a system that is fifteen years old and losing refrigerant, replacement is the honest answer. We handle AC installation in Kennesaw with a load calculation first, because sizing off the old nameplate is how homeowners end up with a clammy house. We look at duct sizing, return air, the condensate path and the crawlspace before we recommend equipment. Red clay crawlspaces around here are hard on line sets and pans, so we plan for that. Call us or send the quote form with the age of your system and what it has cost you lately.

AC Installation in Kennesaw — quick answers

How do you decide what size system my house needs?

We measure the house instead of copying the old label. Room sizes, window area, insulation, ceiling height and duct capacity all go into the calculation. Oversized cooling short cycles and leaves the air clammy, so getting the size right matters more than the badge on the outdoor unit.

Can I keep my existing ductwork?

Often yes, but we check it first. We look at duct size, sealing at the joints, insulation in the crawlspace and attic, and whether the return is big enough for the new system. If the ducts choke airflow, we repair or resize those sections during the install.

How long does an AC replacement take?

A straight changeout of an outdoor unit and indoor coil is usually a one-day job. Add duct repairs, a new line set, electrical changes or a difficult crawlspace and it can stretch into a second day. We tell you which one you are looking at before we start.

Is a ductless mini-split right for my house?

Mini-splits work well for additions, bonus rooms, converted garages, sunrooms and older homes with no duct path. They also help rooms that a central system never reaches. We can install a single indoor head or several off one outdoor unit depending on the layout.

How soon can you get to my Kennesaw home?

Call us and we will tell you honestly where you sit in the day's schedule. Same-day visits are common in Kennesaw when a system is down, and we tighten arrival windows as the day goes so you are not sitting by the door all afternoon.

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.
