Fast, Local AC Repair & Installation

When a condenser stops turning on a July afternoon in Marietta, the heat inside climbs faster than most people expect. Homes along Whitlock Avenue and up toward East Cobb get direct afternoon sun, and a failed AC can push indoor temperatures past 85 degrees within an hour or two. We know this because we’ve worked in those neighborhoods for more than twenty years.

Coldharbour Heating & Air was founded in 2003 as part of the Kingswell network, an independent group of HVAC businesses held to the same written standards. We are independently owned and operated, which means the person accountable for your repair is part of this community, not a distant call center dispatching someone from across the metro.

Our response is straightforward: when you call (762) 240-5599, a live person answers and schedules your appointment. Most AC repairs in Marietta can be completed the same day, often within a few hours of the call. For emergency no-cooling situations, we prioritize your call and give you a firm arrival window, not a four-hour range that slides all afternoon.

What you get on every visit is a background-checked, uniformed technician who arrives in a marked vehicle, introduces themselves at the door, and takes a few minutes to listen before opening a tool bag. The AC repair and installation process in Marietta always starts with diagnosis, moves to a written quote, and only begins work after you approve the price on paper.

We carry the parts most commonly needed for emergency repairs in our vehicles: capacitors, contactors, fan motors, and thermostats. About seven out of ten no-cooling calls we handle in Marietta turn out to be a failed capacitor or a clogged condensate line, both of which can usually be fixed on the spot.

Common AC Problems We Fix in Marietta

Marietta’s climate is hard on air conditioners. High humidity through the summer forces systems to run longer cycles, and the pollen from the area’s dense tree cover clogs outdoor condenser coils faster than in drier climates. Here are the repairs we handle most often:

Refrigerant Leaks and Recharges

Low refrigerant, the cooling fluid your AC needs to run, is a symptom, not a root problem. A system that’s low has a leak somewhere. We find the leak, repair it, and then recharge the system to the manufacturer’s specification. If your system uses R-22 refrigerant, which was phased out in 2020, the cost to recharge has risen sharply, and in many cases replacement is the smarter financial move. We’ll show you the numbers both ways before you decide.

Compressor Failures

The compressor is the heart of your AC, pressurizing the refrigerant so it can move heat out of your home. In Marietta, compressors that run through long, humid summers often fail between years 10 and 15. We diagnose compressors carefully, because Compressor Repair is expensive enough that you deserve certainty before writing a check. If the compressor is under warranty, we handle the paperwork with the manufacturer.

Capacitor and Contactor Replacements

These are the two electrical components that fail most often in Marietta heat. Capacitor Replacement addresses the part that stores the burst of energy needed to start the compressor and fan motor; the contactor is the electrical switch that turns the system on. Both are inexpensive parts on a 20 to 30 minute repair, and skipping them leads to bigger failures down the line.

Frozen Evaporator Coils

A frozen coil is almost always an airflow problem: dirty filter, closed vents, or a failing blower motor. The ice melts into water that can damage ceilings and walls. We thaw the system, find the cause, and correct it so the problem doesn’t repeat on the next hot day.

How Much Does AC Repair Cost in Marietta?

Straight answer: most AC repairs in Marietta run between $180 and $450, with the final price depending on the part and the system. We give you a written price before any work begins, and that number does not change at the door. Here’s what to expect:

  • Capacitor replacement: $180 – $280
  • Contactor replacement: $150 – $250
  • Condensate drain clearing: $120 – $220
  • Thermostat replacement: $180 – $350, depending on the model
  • Condenser fan motor replacement: $325 – $500
  • Evaporator coil replacement: $1,200 – $2,200
  • Full AC system installation: $6,500 – $14,000, depending on size and brand

These numbers reflect what we charge in Marietta, not national averages that don’t match local reality. And because every repair includes the 365-Day Done Right Promise, if the part fails again in 12 months, the second fix costs you nothing.

AC Installation in Marietta

When a repair no longer makes financial sense, or your system is past year 15 and eating you alive on power bills, AC Replacement may be the better option, and we install complete systems for homes throughout Marietta. Our technicians are trained on nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We don’t push one brand; we match the right system to your home’s square footage, duct configuration, and budget.

Here’s how an installation with Cold Harbour works:

  1. Call us at (762) 240-5599. A live person answers and schedules a time that works for you. No voicemail trees, no callbacks.
  2. We assess your home. A technician measures square footage, checks ductwork, evaluates insulation, and reviews your current system’s age and condition. This step takes about an hour.
  3. You receive a written price. The full cost of the installation, including equipment, labor, and any duct modifications, is written down and handed to you before any work begins. That price is final.
  4. We install your new system. Our techs protect your floors, remove the old equipment, install the new system, and leave the work area cleaner than they found it. This is part of The Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails.

A new AC installation in Marietta is a significant purchase, and you should never feel rushed into it. We answer every question, show you the numbers on efficiency versus cost, and let you decide on your own timeline.

Areas We Cover

We’re based in Marietta and serve the surrounding communities of Cobb County and the northwest metro. If you live in any of the following areas, we can usually reach you the same day you call: Marietta, Roswell, Woodstock, Smyrna, Fair Oaks, North Decatur, Dallas, and Holly Springs. If you’re not sure whether we cover your neighborhood, call (762) 240-5599 and ask. A live person will tell you straight.

The name Cold Harbour comes from an old English term: a cold harbour was a roadside shelter where travelers could wait out bad weather. That idea guides how we work. An AC system should be a shelter from the Georgia heat, and it’s our job to make sure yours works when you need it most.

What Our Customers Say

★★★★★ 5.0 from 3+ reviews

"AC quit on the hottest day of the year of course. Coldharbour had a tech out that evening, found a bad capacitor, and had us cool again within the hour. Charged the quote, not a penny more."

- Doug Feeney

"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."

- Russ Tiedemann

"Signed up for a tune up before summer. He found a part starting to fail and showed me the reading, didn't just tell me to trust him. Fixed it then so we wouldn't get stuck in July."
