Credentials That Matter for Atlanta HVAC Installation
Our dealer and contractor credentials aren’t marketing designations. They reflect verified performance in training, installation quality, and customer satisfaction reviewed independently by the manufacturers themselves.
- Dave Lennox Premier Dealer: Premier status is maintained through an independent customer-satisfaction review process and requires meeting Lennox’s ongoing performance standards, giving you access to premium Lennox equipment installed by a team the manufacturer has vetted.
- Mitsubishi Elite Diamond Contractor: The highest accreditation level in Mitsubishi’s Diamond Contractor Program, earned through performance in sales, training, service after the sale, and verified customer satisfaction. It’s the credential you want behind a ductless mini-split installation.
- NATE & EPA Certification: Our technicians hold nationally recognized NATE certification confirming professional competency in HVAC installation, along with EPA Section 608 certification required for refrigerant handling.
Cunningham Associates has been a Certified Best Pick through Best Pick Reports since 2005 and has received multiple Angie’s List Super Service Awards. We participate in Georgia’s Drug-Free Workplace Program and conduct employee drug screening, so the technician who arrives at your home has been background-verified. We’re available 24/7 for urgent installation needs and don’t charge extra for evenings or weekends.

HVAC Systems We Install & When Replacement Makes Sense
We install and replace the full range of residential HVAC equipment: central air conditioning systems, heat pumps, gas furnaces, and ductless mini-split systems. As a Dave Lennox Premier Dealer and Mitsubishi Elite Diamond Contractor, we have direct access to equipment from two of the most recognized manufacturers in the industry.
Recognizing When Replacement Is the Right Call
Most residential systems have a service life of 10 to 15 years. If yours falls in that range and is requiring frequent repairs or struggling to hold consistent temperatures through an Atlanta summer, replacement is often the more cost-effective path. Newer systems carry significantly higher SEER2 ratings than equipment installed a decade ago, which can translate to lower monthly energy costs during the region’s long cooling season.
Sizing & Load Calculations
Proper sizing matters as much as equipment selection. Before recommending a system, we perform load calculations that account for your home’s square footage, insulation, windows, and ductwork. An undersized system runs constantly without reaching your target temperature. An oversized one short-cycles and leaves indoor humidity uncontrolled. Atlanta’s older homes inside the Perimeter and newer builds in surrounding communities each present their own installation variables, and our team has worked through them across more than two decades of local service.
How the HVAC Installation Process Works
The process starts with a free estimate on select services. A technician visits your home, assesses the current system and mechanical space, reviews your ductwork, and recommends equipment sized for your specific conditions. You get a clear picture of the work involved and the options available before any commitment.
A full replacement typically includes removing the old system, installing the new indoor and outdoor units, connecting to existing ductwork or installing new ductwork if needed, refrigerant charging, electrical connections, and a complete system startup test. HVAC installation in Atlanta and Fulton County requires permits, and we handle that process as part of the job.
Our NATE-certified technicians perform every installation. If your system fails during peak summer heat and you can’t wait, our 24/7 availability means we can address emergency replacements outside standard business hours without additional fees.
Schedule Your Atlanta HVAC Replacement Estimate
If your system is aging, underperforming, or has failed outright, don’t wait through another Georgia summer. Our team is ready to assess your home and recommend the right equipment for your situation.
