A new air conditioner is a big purchase, and in Atlanta’s heat, it’s a purchase you can’t afford to get wrong. When the temperature climbs past 95 in July and your old system gives out, you need a company that shows up, quotes a fair price in writing, and installs the unit correctly the first time. Coldharbour Heating & Air has served Atlanta homeowners since 2003 as an independently owned member of the Kingswell network. We answer the phone with a live person around the clock, every day of the year. If your AC has failed or is nearing the end of its life, call (478) 223-8776 and we’ll walk you through your options honestly. Victor Mancini, our owner, built this company on one idea: put everything in writing before the work begins, and stand behind it after. That’s The Kingswell Way, and it applies to every AC installation in Atlanta we perform.
Furnace Installation
Furnace Installation means replacing or newly installing the gas or electric heating unit that warms your home’s air and pushes it through the ductwork. You need it when your existing furnace has a cracked heat exchanger, rusted burners, or is more than 15 years old and costing you repeated repairs. A typical furnace installation in Atlanta runs $3,500 to $7,500 depending on the unit’s size, efficiency rating, and whether ductwork modifications are needed. Coldharbour Heating & Air always hands you a written price before any work begins, and every installation includes the 365-Day Done Right Promise.
When Replacement Beats Another Repair
A furnace that is 12 years old or older, needs a blower motor replaced, and has already had two repairs this winter is telling you something. Put that repair money toward a new high-efficiency unit instead. We will show you the math honestly, and we never pressure you either way.
Sizing Done Right
A furnace that is too big short-cycles and wastes gas. One that is too small runs constantly and still leaves cold spots. We measure your home’s square footage, ceiling height, insulation levels, and window orientation before recommending a unit, so the furnace fits the house, not the other way around.
Styles & brands we work with







HVAC Installation
HVAC Installation covers the full heating and cooling system: the furnace or air handler, the air conditioner or heat pump, the thermostat, and often the ductwork connections. You need it when your home’s entire comfort system is outdated, mismatched, or was installed incorrectly by a previous contractor. Full HVAC installation in Atlanta typically costs $3,500 to $7,500, with the final number driven by system size, brand, and efficiency level. Coldharbour Heating & Air technicians are trained on Carrier, Trane, Lennox, and American Standard equipment, so whatever system fits your home best, we can install it properly.
Matched Systems Matter
Equipment installed as a mismatched pair – a high-efficiency condenser on an older furnace, for example – often fails early and rarely delivers its rated efficiency. We install matched systems that share a manufacturer’s AHRI rating, which protects your warranty and your energy bills.
Ductwork We Actually Check
Leaky or undersized ducts can waste 20 to 30 percent of the air your system produces. Before we quote any HVAC installation, we inspect accessible duct runs and factor sealing or replacement into your written price. Most companies skip this step. We don’t.
Heat Pump Installation
Heat Pump Installation is the process of installing a single system that both cools and heats your home by moving heat rather than burning fuel or running electric resistance elements. You need it when you want to replace an aging air conditioner with something that handles Atlanta’s shoulder seasons more efficiently, or when you’re adding central comfort to a home without gas service. A heat pump installation in Atlanta commonly runs $3,500 to $7,500, influenced by the unit’s HSPF and SEER ratings and whether backup heat strips are required. Coldharbour Heating & Air provides a written price before work starts, and the installation carries our 365-Day Done Right Promise.
Cold-Climate Models for Atlanta Winters
Atlanta does get freezing nights, and a standard heat pump loses capacity as the outdoor temperature drops. We can install cold-climate-rated units that keep working efficiently down into the 20s, so you won’t watch your backup heat run all January. For most Atlanta homes, a properly sized heat pump handles 90 percent of the heating season.
Why SEER and HSPF Both Count
SEER is the cooling efficiency rating. HSPF is the heating one. Many homeowners get quoted a high SEER and never ask about heating, then wonder why the winter bill moved. We walk through both numbers before installation, so you know what you are buying in every season.
Ductless Mini Split Installation
Ductless Mini Split Installation means mounting one or more wall, floor, or ceiling units connected by slim refrigerant lines to an outdoor compressor, giving you room-by-room climate control without ductwork. You need it when you’re finishing a garage or attic, your home has boiler heat and no ducts, or you have one room that never gets comfortable. Ductless installation in Atlanta runs $3,500 to $7,500 depending on how many indoor zones you need and the total BTU capacity. Coldharbour Heating & Air sends uniformed, background-checked technicians to every job, and the written price you get before installation is the price you pay.
Zoned Comfort, Room by Room
A ductless system lets you set different temperatures in different rooms. That means the sun-blasted upstairs bedroom can run cooler while the shaded downstairs stays warmer. For homes with add-on spaces or stubborn hot spots, that control changes how the whole house feels.
When Ductless Beats Extending Ducts
Some Atlanta homes, particularly older ones with radiator heat, would need extensive and invasive ductwork to support a central system. A ductless mini split avoids all that. We’ll show you the side-by-side cost of extending ducts versus going ductless before you commit to anything.
AC Replacement
AC Replacement is the job of removing your old, failing outdoor condenser and indoor coil (and often the furnace or air handler) and installing a new, correctly matched cooling system. You need it when your current AC is over 12 years old, uses R-22 refrigerant, needs a compressor replacement, or has needed three or more service calls in the last two summers. AC replacement in Atlanta generally costs $3,500 to $7,500, and the price depends on the brand, tonnage, and efficiency level you choose. Coldharbour Heating & Air provides a written price before any work begins and backs every replacement with the 365-Day Done Right Promise.
R-22 Phaseout Means Replacement Math Changed
If your existing system runs on R-22 refrigerant, a recharge now costs a fortune because the refrigerant is no longer manufactured or imported into the U.S. at scale. Atlanta homeowners in that situation usually find replacement is the smarter money. We’ll check your system’s refrigerant type during the estimate and factor that into your decision honestly.
Efficiency Rebates Are Worth Asking About
Georgia Power and some local utilities in the Atlanta area offer rebates for high-efficiency AC replacements, and federal tax credits often apply. We’ll point you to the programs that fit your system choice at no extra charge. The rebate paperwork is handled as part of the job.
Central Air Conditioning Installation
Central Air Conditioning Installation is the process of installing a full split system: an outdoor condenser, an indoor evaporator coil, refrigerant lines, a condensate drain, and the thermostat wiring and controls that tie it together. You need it when your home has ductwork but no working central cooling, or when the existing central unit is beyond economical repair. AC Installation in Atlanta runs $3,500 to $7,500. The bigger your home’s square footage, the more tonnage you need, and that moves the price. Coldharbour Heating & Air will give you an exact written quote before any work starts, and the installation is covered by our 365-Day Done Right Promise.
The Condenser Pad and Clearance Details
A new outdoor unit needs a level pad, proper clearance from walls and shrubs, and correct electrical disconnect placement. These details get skipped by rushed installers and fail inspection later. We handle pad leveling, code clearance, and disconnect wiring as standard, and the work passes Atlanta code on the first inspection.
Startup and Commissioning Matter More Than the Box
A new system is only as good as its startup. We check refrigerant charge with digital gauges, verify airflow across the coil, measure temperature drop, and confirm the system cycles correctly before we leave. That is the difference between a unit that lasts 8 years and one that lasts 15.
Brands We Service
Our technicians are trained to install and service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Every technician carries the training and factory documentation to install these brands to the manufacturer’s specification, which protects your warranty and your system’s lifespan.
We stock common OEM parts for Trane, Carrier, and American Standard units on our trucks, so many repairs on those brands happen in a single visit. If your home runs a Bryant, Lennox, Rheem, York, Daikin, or Goodman system, our techs know those units inside and out too. Whether you have a Trane that’s 15 years old or a brand-new American Standard, the technician who walks through your door can diagnose it and fix it correctly.

- No cooling on a hot day. If your thermostat is set to 74 but the house is climbing past 82, and the vents are blowing warm air, the compressor may have failed or you have a major refrigerant leak. In Atlanta’s summer heat, this is a health risk for children, elderly residents, and pets. Don’t wait it out.
- Ice on the outdoor unit or refrigerant lines. Ice on the copper lines running to the condenser means the system is low on refrigerant or starved for airflow. Left running, a frozen system can destroy the compressor, turning a $300 repair into a $3,500 replacement. Shut it off and call us.
- Strange noises at startup or during operation. A grinding, screeching, or banging sound often means a failing compressor, fan motor bearing, or blower wheel. These parts typically give 10 to 15 years of service, and when they start making noise, they are not going to fix themselves. Early attention usually saves the big bill.
- Short cycling (turning on and off every few minutes). A system that starts, runs 5 minutes, shuts off, and repeats is short cycling, usually from a refrigerant level issue or an oversized unit. Short cycling wastes electricity, wears the compressor out prematurely, and barely dehumidifies the house. It needs a pro’s diagnosis.
- Water pooling around the indoor unit. A clogged condensate drain or cracked drain pan lets water drip onto your floor or ceiling. Beyond the water damage risk, it leads to mold and can cause the system to shut down entirely. This is an easy fix if caught early, and a costly one if ignored.
Our Process, Step by Step
- 1
Call, and a live person answers. You call (478) 223-8776 and speak to a real human being, not a phone tree. We’ll ask about your current system, its age, the size of your home, and what symptoms it is showing. We schedule an estimate at a time that works for you, with a firm arrival window.
- 2
We arrive on time and do a full walkthrough. Our technician arrives in uniform, introduces himself, and inspects your existing system, ductwork, thermostat, and electrical panel. We measure your home’s square footage and check insulation, window exposure, and ceiling height. You get a complete picture of what your home actually needs.
- 3
You get a written price before any work begins. We write down the system recommendation, the equipment model numbers, the scope of work, and the exact price. That price does not change at the door, and you get a copy. There is no pressure to sign that day, and no hidden add-ons appear later.
- 4
We install the system cleanly and to code. The installation team removes old equipment, installs the new system to manufacturer spec, and handles permits. We put down drop cloths and shoe covers, and we clean up every scrap and screw before we leave. The work passes Atlanta building code.
- 5
We test everything and put the guarantee in writing. Before we leave, we run the system through a full startup checklist: refrigerant charge, airflow, temperature split, and cycle testing. We give you a written copy of the 365-Day Done Right Promise. You sign nothing else. If anything malfunctions in the next year, we return and fix it at no charge.
How Much Does AC Installation Cost in Atlanta?
A new AC Installation pricing in Atlanta typically runs $3,500 to $7,500 installed. The most common installations land around $4,500 to $5,800 for a 3-ton unit with a 14 to 16 SEER rating in a standard single-family home. Smaller homes in Grant Park or East Atlanta that need a 2-ton system often come in at the lower end, while larger homes in Buckhead, Sandy Springs, or Morningside requiring a 4 to 5 ton system with high-efficiency ratings and ductwork modifications run toward the top.
What moves the price: the size of your home (tonnage), the SEER efficiency rating you choose, the brand, the condition of your existing ductwork, and whether any electrical or thermostat upgrades are needed. A 13 SEER unit is cheap to install and expensive to run. A 20 SEER unit is the reverse. We help you find the sweet spot based on how long you plan to stay in your home.
How to avoid overpaying in Atlanta: get a written quote that itemizes equipment, labor, and any sheet metal or electrical work. Never accept a verbal number. Ask whether the quote includes a new thermostat, a new pad, a new disconnect, and a new refrigerant line set. Our free estimate includes all of that in writing, and our price is the price, period. Call (478) 223-8776 and we’ll come out at no charge and put your number on paper.
