Furnace Replacement in Marietta, GA

Furnace replacement across Marietta usually comes up after a cracked heat exchanger, a rusted-through burner assembly, or a unit that has needed three repairs in two winters. We look at what fuel you have, whether a heat pump pairing makes sense, and how the venting runs before recommending anything. Ductwork and return sizing get checked too, because a new furnace pushed through undersized returns stays noisy and short-cycles. Give us a call to talk options, or fill in the quote form and we will schedule a look.

What brings Marietta homeowners to this job

We have had heating repair out three winters running Repeat failures on an aging heat exchanger, board or inducer motor
It kicks on, runs two minutes, shuts off, then does it again Short cycling from oversizing, restricted return air or a failing limit switch
There is a burnt or sooty smell when the heat starts Combustion or heat exchanger problem that needs inspection before any replacement talk

What a furnace replacement job involves

We start with a load calculation for your actual house, not a match to the old nameplate. Older furnaces in foothill homes are often oversized, which is why rooms overshoot then go cold. From there we handle removal of the old unit, gas line and venting connections, condensate routing, electrical, and duct transitions at the plenum. Crawlspace installs get extra attention because red clay stays damp and holds it. We finish with a startup, combustion and airflow checks, and a walkthrough of the new thermostat.

What we check and what we install

Before quoting anything we look at your ductwork, return air, filter location, flue condition, and gas pressure at the unit. A new furnace fed by undersized returns will run hot and fail early, so we call that out up front. We install gas and propane furnaces, and dual-fuel setups where a heat pump handles mild days and the furnace takes the cold snaps up on the ridges. Where the old venting no longer suits the new equipment, we replace it rather than reuse it.

How we decide replacement is the right call

Repair is usually the better answer, and we will say so. Replacement makes sense when the heat exchanger is cracked, when parts for the model are no longer available, when repair costs are stacking up on a system well past its expected years, or when the furnace can no longer keep the house at setpoint on a cold morning. We show you what we found and give you both paths. Nobody on our crew works on commission, so the choice stays yours.

Furnace Replacement in Marietta — quick answers

How long does a furnace replacement take?

Most straightforward swaps are a single day. Jobs that need new venting, duct transitions, or work in a tight crawlspace can run into a second day. We tell you which one you are looking at before we start.

Can I put a new furnace on my existing ductwork?

Often yes, but we measure first. If returns are undersized or the trunk lines leak badly, we will recommend repairs alongside the install so the new furnace is not fighting the duct system every cycle.

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.
All major brands, gas & electricOne independent crew for Carrier, Trane, Lennox, Goodman, Rheem and more.
