AC Replacement and Installation in North Georgia

A new air conditioner only cools and pulls humidity out of the house the way it’s rated to when it’s sized, charged and set up for your home. Comfort Medics replaces and installs central air conditioners for homeowners across North Georgia from our base in Kingston. We’re licensed and insured (GA. REG. CR2011437), the owner has 17 years in HVAC, and a real person answers our phone 24/7.

Repair or Replace Your AC? We Price Both

If your air conditioner has quit or keeps needing repairs, we check it and give you pricing on both options so you can decide. A repair visit has a $125 service fee, credited toward the repair when you go ahead with the repair or a new system. Comfort Club members don’t pay service fees. If you already have a replacement quote from someone else, a second opinion before you decide is free. For more on the decision, see repair or replace your HVAC system: 5 things to check.

What We Look At During Your Free In-Home Estimate

An air conditioner is two halves that have to match: the outdoor condenser and the indoor coil, which usually sits on your furnace or air handler. The estimate covers more than the outdoor unit:

• your current outdoor unit, indoor coil and the furnace or air handler they work with
• the ductwork the system blows through
• the refrigerant lines, and whether they can be reused
• the electrical supply and disconnect for the new equipment
• the condensate drain, so water can’t damage ceilings or floors

We size the new system with a load calculation for your home, not by matching the old unit’s label. You get an exact, upfront price before any work is scheduled. Removal and disposal of your old equipment is included.

Installation Day: How We Commission a New AC

Most changeouts take about 2–3 hours. Ductwork or electrical changes, when they’re needed, can add time. We pull the permit on every replacement and install to the manufacturer’s requirements. Then we commission the system, as these steps apply to your equipment:

• flow nitrogen while brazing and pressure test to the manufacturer’s specifications
• flush existing refrigerant lines when reusing them is appropriate
• pull a deep vacuum and verify it holds
• verify the refrigerant charge with superheat and subcooling, and evaluate the TXV where the equipment supports it
• measure airflow and total external static pressure
• check supply voltage, amp draws and control-board settings
• confirm the condensate drains properly before we leave

These are the same checks in the Comfort Medics Installation Standard that we use on every new system.

AC Prices (as of November 2026)

Installed starting prices for our air conditioner replacements in North Georgia:

• Air conditioner only: starting at $5,000 (typically $5,000 to $10,000)
• Evaporator coil: starting at $2,000 (typically $2,000 to $4,000)
• Complete system (air conditioner and furnace): starting at $7,000 (typically $7,000 to $18,000)

Your final price depends on your home’s size, the capacity it needs, the efficiency level you choose, ductwork, refrigerant line and electrical work, where the equipment sits, and permit fees. For the full breakdown, see our HVAC replacement cost guide for North Georgia.

Replacing Your Furnace at the Same Time?

It depends on the age and condition of each one. At the free in-home estimate we look at both and price each option, so you can decide what makes sense for your home. See furnace replacement for how we handle the heating side.

AC or Heat Pump?

A heat pump looks like an air conditioner on the outside, but it heats the house as well as cooling it. A regular AC only cools; heat still comes from a furnace or another heat source. If you are replacing the outdoor unit anyway, we can price both options at the same free in-home estimate so you can compare them on your house, not on a generic chart.

An AC paired with a gas furnace still makes sense when you already have gas service and a furnace that has years left, or when you want gas heat on the coldest days. A heat pump makes sense when you want one outdoor unit to handle both heating and cooling, or when you are already replacing the indoor unit too. We also install dual-fuel systems — a heat pump paired with a gas furnace — and 95%+ high-efficiency furnaces. Which setup fits depends on the gas line, the electrical panel, the existing indoor equipment and the ductwork. We check all of that in person.

As of November 2026, our installed air-conditioner-only replacements start at $5,000 (typically $5,000 to $10,000). A complete AC-and-furnace system starts at $7,000 (typically $7,000 to $18,000). An outdoor heat pump unit alone starts at $2,000 installed (typically $2,000 to $6,000, air handler not included), and a complete heat pump system starts at $7,000. Your final price depends on the size your home needs, efficiency level, ductwork, electrical work, where the equipment sits, and permit fees. Those heat pump figures are the same ones on our heat pump installation and replacement page. For the full cost breakdown, see our HVAC replacement cost guide.

Every replacement includes a load calculation (we do not just copy the old unit’s size), permit, and haul-off of the old equipment. Typical changeouts take about 2–3 hours. New systems include a 10-year manufacturer parts warranty on qualifying equipment (registration may be required), a 10-year labor warranty from Comfort Medics, and our lifetime craftsmanship guarantee. Details are on our HVAC warranty page. If the furnace is part of the decision, see furnace replacement.

AC Replacement FAQ

How much does a new AC cost?

As of November 2026, our installed air-conditioner-only replacements start at $5,000 and typically run $5,000 to $10,000. A complete system (AC and furnace) starts at $7,000. You get an exact price after a free in-home estimate.

How long does an AC replacement take?

Most changeouts take about 2–3 hours. Ductwork or electrical changes, when they’re needed, can add time.

How do you decide what size AC I need?

We run a load calculation for your home on every replacement instead of copying the size of the old unit.

Do I need to replace the indoor coil too?

Often, yes. The outdoor unit and indoor coil have to be matched, and newer outdoor units use newer refrigerants, so an older coil often has to be replaced too. We check that at the estimate and price it.

Do you haul away the old unit?

Yes. Removal and disposal of your old equipment is included.

Do you pull a permit?

Yes. We pull the permit on every replacement.

What warranty comes with a new AC?

A 10-year manufacturer parts warranty on qualifying equipment (registration may be required), a 10-year labor warranty from Comfort Medics and our lifetime craftsmanship guarantee.

Is the estimate really free?

Yes. In-home estimates for a new system are free. A second opinion on someone else’s replacement quote is also free.
