If your residential and commercial HVAC system is more than 10 years old

Update Older Units If your residential and commercial HVAC system is more than 10 years old then chances are it’s not energy efficient at all! Older furnaces and air conditioning units were power hungry because they didn't have any kind of energy-saving features and parts installed in them. Over time, as the technology progressed, newer residential and commercial HVAC systems started to have energy-saving features that is why they are able to provide outstanding performance without taking a lot of power. If you have had your furnace and air conditioning unit for more than ten years, it’s probably time for a major upgrade or outright replacement.
