If your system is breaking down more often than it used to — or your energy bills have quietly crept up year after year — you’re probably wondering whether it’s time to replace it. The big question most homeowners ask first:
what is this actually going to cost me?
The answer depends on several factors, but this guide will walk you through what to expect for HVAC replacement costs in Marietta so you can plan with confidence.
What Affects the HVAC Replacement Cost in Marietta?
The HVAC replacement cost in Marietta typically ranges from
$10,000 up to $30,000
, depending on your home’s size, the type of system you need, and the complexity of the installation. When replacing an air conditioner, the indoor coil must be replaced as well, which ranges between $7,500 – $11,500. Here are the main factors that move the price up or down:
Home size and system capacity.
Larger homes need larger systems. A 1,500 sq ft home might need a 2.5-ton unit, while a 3,000 sq ft home could require a 5-ton system. Bigger capacity means higher equipment and labor costs.
System type.
A standard split system (the most common setup) costs less than a heat pump or a zoned system. Ductless mini-splits are another option — great for additions or older homes without ductwork.
Brand and efficiency rating.
Higher SEER2-rated equipment costs more upfront but lowers your monthly utility bills. Many Marietta homeowners find the investment pays off within a few years.
Ductwork condition.
If your ducts are leaking, undersized, or need to be replaced entirely, that adds to the overall project cost.
What Does a New Air Conditioner Replacement Cost?
For homeowners replacing just the cooling side of their system, the air conditioner replacement cost in Marietta typically falls between
$3,500 and $7,500
, including equipment and installation labor. Central air conditioner pricing varies by:
-
Tonnage
(1.5 to 5 tons for most residential homes)
-
SEER2 efficiency rating
(higher is more efficient but costs more)
-
Brand and warranty terms
-
Whether the air handler or coil also needs replacement
It’s common for the indoor and outdoor components to age together. Replacing only half the system can reduce efficiency and may void manufacturer warranties.
What Is the Furnace Replacement Cost for Marietta Homeowners?
If your heating is the primary concern, furnace replacement costs in Marietta generally run between
$2,500 and $5,500
, installed. Key pricing factors include:
-
Fuel type
— gas furnaces are most common in Marietta; electric or propane units may cost differently
-
AFUE rating
— higher efficiency models (90%+ AFUE) cost more but save on gas bills
-
BTU output
— sized to your home’s heating load
-
Venting requirements
— two-stage or modulating furnaces with PVC venting may require extra installation work
What About a Full System Replacement?
Replacing both the heating and cooling system together is often the smartest financial move. Many homeowners save on labor costs by bundling the work, and you ensure the equipment is matched for peak efficiency. Full system replacement in Marietta can run
$7,000 to $13,000+
, depending on system type and home size.
Are There Ways to Lower Your HVAC Installation Cost in Marietta?
Yes. A few ways to make the project more affordable:
Utility rebates.
Georgia Power and other local utilities sometimes offer rebates for high-efficiency equipment. Ask your installer if current rebate programs apply to your system.
Manufacturer financing.
Many HVAC brands offer promotional financing options, especially during peak seasons.
Compare quotes.
Always get at least two or three quotes from licensed HVAC contractors in the Marietta area. Make sure each quote covers the same scope of work.
Frequently Asked Questions
How long does HVAC replacement take?
Most residential HVAC replacements in Marietta are completed in one day. Complex installations involving ductwork repairs or new system configurations may take two days.
Is it better to repair or replace my HVAC system?
A general rule: if the repair cost exceeds 50% of the replacement cost and your system is more than 10–12 years old, replacement is usually the smarter investment. Newer systems are significantly more energy efficient.
Does HVAC replacement include a warranty?
Yes. Most new systems come with a manufacturer’s parts warranty (typically 5–10 years) and a separate labor warranty from your installer. Always ask about both before signing.
