Introduction
Hey, Tony Marino here. Over the years, I’ve seen how a quality HVAC system installation can make or break your home’s comfort and energy bills. But here’s the kicker: even the best 3 ton R-32 AC and gas furnace won’t perform as promised if the installer cuts corners.
Finding a reliable HVAC contractor for your installation is crucial. So in this guide, I’m going to share what I look for when hiring a contractor — the certifications, experience, customer service qualities, and red flags you should know.
If you want your new HVAC system to run efficiently, last long, and keep you comfortable without surprise costs, this is the blog for you.
🔍 Why Choosing the Right Contractor Matters
You might be thinking, “Can’t anyone install an AC and furnace?” The answer is no — not when you want it done right.
Poor installation leads to:
-
Reduced energy efficiency (up to 30%, according to the Department of Energy)
-
Frequent breakdowns and costly repairs
-
Voided warranties
-
Uneven heating and cooling
-
Safety hazards
Choosing a reputable contractor ensures your 3 ton R-32 AC and gas furnace system will perform at peak efficiency and last for years.
✅ What Certifications and Credentials Should You Look For?
1. NATE Certification
The North American Technician Excellence (NATE) certification is the industry standard for HVAC techs. It ensures the technician has passed rigorous tests and keeps up with the latest technology.
You can verify certified techs on the official NATE website.
2. EPA Section 608 Certification
Because your system uses R-32 refrigerant, your contractor must be certified under EPA Section 608 to handle refrigerants safely and legally. This is a federal requirement.
Learn more about this certification on the EPA’s Section 608 page.
3. License and Insurance
A licensed contractor complies with state and local laws. They should also have liability insurance and workers’ compensation — don’t hire anyone who can’t provide proof.

🛠️ Why Experience With R-32 Matters

Contractors unfamiliar with R-32 can cause leaks, void warranties, and create safety hazards. Make sure your installer is up to date on R-32 best practices.
