Current Offers

Free Estimate on Any New AC Installation

If your air conditioner is 12 years old or more and you’re weighing repair against replacement, we’ll come to your Marietta home and give you a written, fixed-price estimate for a new system at no charge. Victor Mancini often walks homeowners through this one personally, comparing what a repair buys you versus what a new system costs per year of expected life. Valid through March 31, 2027. Mention this offer when you call (762) 240-5599.

Seasonal Furnace Tune-Up at Current Rate, Written Report Included

Before the first cold snap hits Cobb County, have one of our background-checked technicians go through your furnace top to bottom, including the heat exchanger, burners, and safety controls. You get a written report of what was found, and our techs are not paid on what they sell, so the report is what it is. Valid through March 31, 2027. Mention this offer when you call (762) 240-5599.

First-Time Customer Courtesy on Any Repair

If you’ve never called Cold Harbour Heating and Air before, ask about our first-time customer courtesy when you book your AC or furnace repair. You’ll still get the written price before work starts, and the repair still carries the full 365-Day Done Right Promise in writing. Valid through March 31, 2027. Mention this offer when you call (762) 240-5599.

Senior and Military Courtesy on Any Service

We extend a standing courtesy to seniors and active-duty or retired military on any repair or installation. It applies to the labor portion of the job and it’s applied automatically when you let our dispatcher know you qualify. Valid through March 31, 2027. Mention this offer when you call (762) 240-5599.

AC Repair Diagnostic Applied to the Repair

When a technician comes out to diagnose what’s wrong with your AC and you go ahead with the repair the same visit, we apply the diagnostic toward the total. You see the written price before any tool comes out of the truck, so you know exactly where that credit lands. Valid through March 31, 2027. Mention this offer when you call (762) 240-5599.

Furnace Repair Guarantee, 365 Days, Written Before We Leave

Every furnace repair already comes with our written guarantee, good for a full year. If it fails inside that window, we return and correct the work at no charge. It’s not verbal, not conditional, it’s on paper. Valid through March 31, 2027. Mention this offer when you call (762) 240-5599.

Why Marietta Homeowners Use These Offers

These specials are not gimmicks. Cold Harbour Heating and Air has been serving Marietta since 2003 as an independently owned and operated member of the Kingswell network. Every job follows 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 cold harbour was a roadside shelter where travelers waited out the weather. Comfort in any season is the job. That’s why the offers above are straightforward and apply to whatever brand of equipment is already in the home. Our technicians train on nine major residential brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard.

When summer hits Marietta and the humidity makes a broken AC feel like an emergency, or when January nights drop into the 20s and a furnace quits, the last thing you want is a bait-and-switch coupon. You want a number, a window, and a written guarantee. That’s what these specials deliver.

If you’re not sure which offer applies to your situation, call anyway. A live person answers the phone around the clock, every day of the year. Tell us what your system is doing and we’ll point you to the right starting point.
