What it is, and why it matters.
Variable-speed equipment runs at the speed the house needs instead of full blast and off. The result is steadier temperatures, better humidity control, quieter operation and lower electricity use, since slower speeds are very efficient.
We explain what to expect, show you the efficiency ratings, check that your ducts can handle the lower, longer airflow and recommend the level that makes sense for your home and budget.
