Armstrong 418LE Central Air Conditioner Installation

Installation prices can vary for a number of reasons.  Some homes offer easy installation and some are more complex.  If extra refrigerant and lines are used, the price will go up. Installation in an attic or crawl space costs more than installation in a first-floor utility room. You get the point.  Specific factors produce a range in installation costs. These prices don’t include the installation of a gas furnace too.  For a complete HVAC system installation, the price may be double.  For just the AC, your installation should be $1,200-$2,200.


It always makes sense to get at least 3 estimates for the cost of the air conditioner and the installation cost.
