Last week I had my home A/C serviced, the guy cleaned up all the required items gave it a shot of Freon, and gave my system a clean bill of health. :thumleft:
But he said the return air on my system was a bit undersized, which could be causing my A/C to run more than it should, and he included a quote to increase the return air capability of my system for what seemed to be a reasonable, but I'd like to make sure.
Is anybody here a home A/C wizz? What is the formula for calculating return air for a home A/C system??
TIA
