Home Heating Recommendations by Our Trained Technicians

Installation Approach

FACT: The EPA estimates that nearly HALF of all existing heating and cooling equipment is oversized (too big!) They estimate this costs an average of 20% in wasted energy each year.

The most important day in the life of your heater and air conditioner is the day it is installed. Proper installation, as well as choosing the right size equipment, accounts for almost 75% of the operating efficiency and performance of the system you buy.

At Heritage we GUARANTEE you get the RIGHT system for your home and that it will be installed correctly.
