Taking the right steps to increase the efficiency of your heating and cooling system can have a big impact on your utility bills, as well as the comfort and health of your home.

Replace an old, inefficient, or oversized HVAC system

An older HVAC system has two main disadvantages. First of all, it’s unreliable, forcing you to pay high maintenance and repair bills. Secondly, an older HVAC system is inefficient, which means that you end up paying too much to stay comfortable in your home.

Any HVAC system that’s more than 15 years old is probably causing both of these problems. But even a well-functioning older system can be expensive to operate because of  it’s inefficiency. For example, a 20-year-old furnace probably operates at a maximum of 75% efficiency even when it’s in perfect condition.

According to the U.S. Dept. of Energy, an older furnace or boiler operates with an efficiency of 56% - 70%. A new, high-efficiency furnace can operate at 96% efficiency. Depending on the cost of fuel and electricity, an upgrade to a high-efficient HVAC system can pay for itself in just a few years.

High-efficiency air conditioner & heater upgrades and replacements

In the U.S. and around the world, HVAC technicians have made huge gains in heating and cooling technology. Today, ultra-high-efficiency furnaces and boilers are available that deliver up to 96% efficiency.

A high-efficiency HVAC system looks and works differently than old-style equipment. It’s compact, quiet and reliable. Instead of requiring a chimney to vent flue gasses, a high-efficiency furnace and boiler relies on plastic pipe.
