Why Old HVAC Units Are Bad for the Environment

Posted on AC Tips, Blog April 15, 2018

We all want to get as many years as we can out of the equipment we buy for our homes, but sometimes the dangers and drawbacks of using an old HVAC unit are just not worth it. If you’re trying to decide if its time to buy a new unit, take these factors into account.

Hazardous Chemicals

Older HVAC units commonly use a chemical called R-22 for cooling. In the United States, we now know that this substance is harmful to the ozone layer and contributes to global climate change. As a result, R-22 is being phased out of production and replaced with a refrigerant called R-410A.

Energy Consumption

HVAC systems last about 15 years before they need to be replaced. The technology that goes into these systems advances much faster. The high-efficiency models available today use significantly less energy to heat and cool the same area than those manufactured just a few years ago. Modern units also have a better Seasonal Energy Efficiency Rating (SEER) than older ones. These changes put less strain on the power grid and the natural resources used by the power plants.

The Cost of Disposal

When it’s time to replace your HVAC unit, you can’t just set the old one out with the trash. In fact, in most places, it’s illegal to dispose of an old unit in a landfill because of the hazardous chemicals inside. You may be able to recycle it or hire a professional, like All Year Cooling, to help you out when installing a new one.

The Likelihood of Leaks

As an HVAC unit ages, valves and seals wear out and break down. Tiny spaces allow leaks to develop, releasing refrigerant chemicals into the environment. Most states have laws requiring the homeowner to get these issues repaired right away.

If your HVAC unit is more than 15 years old, it might be time to have it replaced. Visit our website for money saving coupons on the installation of your new HVAC system or talk to a professional about your current unit and get a free estimate today!
