AC Installation & Replacement in Dunwoody
NATE-Certified Technicians. Two Manufacturer Paths. One Right Fit for Your Home.
When a cooling system fails or reaches the end of its service life, the equipment choice matters as much as the installation itself. At Cunningham Associates, our NATE- and EPA-certified technicians guide Dunwoody homeowners through that decision without defaulting to a one-size-fits-all recommendation. We work from what’s right for your home, your budget, and your layout.

Signs Your Dunwoody Home Needs AC Replacement
Most central air conditioning systems have a service life of roughly 10 to 15 years. Dunwoody’s median home was built in 1984, which means many original systems in the area have already passed that threshold. Age alone isn’t always the deciding factor, but it shifts the math on repair costs significantly.
Watch for these replacement signals:
- Frequent repairs: When you’re calling for service multiple times a season, repair costs can exceed what a new system would cost over the same period.
- Rising energy bills: A system working harder than it should to hold temperature is usually losing efficiency, and that shows up in utility costs before it shows up as a complete failure.
- Uneven cooling: Rooms that won’t reach the set temperature, or that swing widely from one end of the house to the other, can indicate a system that can no longer distribute air effectively.
- R-22 refrigerant: The EPA phased out production and import of R-22 in 2020. Systems still running on it face limited, expensive refrigerant supply and are candidates for replacement rather than further repair.
What a Professional AC Installation Includes
A proper installation covers more than swapping equipment. Our technicians start by sizing the new system to your home’s actual cooling load using a Manual J load calculation, which accounts for square footage, insulation, window placement, and local climate. An undersized or oversized system can create comfort and efficiency problems from day one.
From there, the work typically includes removing the old equipment, installing the indoor and outdoor units, connecting refrigerant line sets, and verifying all electrical connections. We also inspect existing ductwork for leaks or damage that could undermine the new system’s performance. The job closes with thermostat calibration and a full system test to confirm the unit is cooling correctly before we leave.

Central Air & Ductless Mini-Split Options for Dunwoody Homes
Not every Dunwoody home has the same layout or the same ductwork situation. That’s why we offer two distinct installation paths, each backed by a manufacturer partnership at the highest tier of its brand.
Lennox Central Air Systems
As a Dave Lennox Premier Dealer, we install and service Lennox central air conditioning systems. Lennox central systems are a strong fit for homes with existing ductwork in good condition, offering high SEER2 efficiency ratings and variable-speed compressor options that help maintain consistent temperatures throughout the home.
Mitsubishi Ductless Mini-Split Systems
As a Mitsubishi Elite Diamond Contractor, we install Mitsubishi ductless mini-split systems for homes that lack ductwork, have additions or converted spaces, or need zoned temperature control. Each indoor unit operates independently, so different rooms can be kept at different temperatures without a shared duct system.
The right choice depends on your home’s structure, not our inventory. Our technicians can assess both options and explain which fits your situation before any equipment is ordered.
Serving Dunwoody Since 2002
Cunningham Associates has served the Atlanta area since 2002. Over more than two decades, our work has been recognized by independent sources: we’ve received the Home Reports Best Pick award and the Angie’s List Super Service Award, both of which reflect consistent performance across real customer experiences rather than self-reported claims.
