How to Know If Your Home’s HVAC Unit Is Up to Code

There are certain codes and standards that must be followed when installing new HVAC equipment. An installation that’s not up to code can cause all sorts of problems, from wasted energy to a damaged system and more. Here’s how to make sure yours is up to code.

  • Sizing. Make sure your HVAC contractor calculates your home’s heating and cooling loads according to Manual J to get the correct-size unit for your home. If you’re replacing an existing unit, you can skip this step and simply get the same size you had before. However, if you’ve had additions to your home or extensive remodeling since installing the old unit, you’ll need a revised load calculation for the altered space.
  • Location. Your unit should be installed somewhere out of the way, but it still needs to be easily accessible for service and maintenance. An attic or crawl space will work in a pinch, but ideally, you should have a small closet specifically for the unit.
  • Matching. If you’re replacing one part of your split-system AC or heat pump but not the other, it’s important that the new unit be compatible with the old unit. Refrigerant travels back and forth between the two and needs similar pressure levels in both.
  • Efficiency. In addition to installation codes, your system must also meet certain efficiency standards. In Georgia, your AC must have a minimum SEER rating of 14, and your gas furnace must have an AFUE rating of at least 80. To maximize energy efficiency, look for a model with the blue Energy Star logo, which shows the system is proven to save money and energy over similar units for the same basic price and performance.
  • NATE certification. To get the best-quality installation and ensure everything is up to code, ask if your HVAC technician is NATE certified. That means they’ve been trained and tested in the equipment you’re purchasing and have both the knowledge and experience to install it properly.
