Proper HVAC system sizing involves much more than square footage. Insulation, windows, layout, air leakage, home orientation, and local climate all affect how much heating and cooling your home actually needs.
A system that’s too large or too small can lead to comfort issues, higher energy costs, and unnecessary wear over time. That’s why proper sizing and installation by a licensed, certified HVAC professional are so important.
