Heating, Cooling and Home Energy Company

For over 25 years, Dean DeMague has worked in the heating and cooling industry. As the owner of High Performance Energy Solutions, Dean realized that homeowners really need help making their homes more energy efficient. Between construction, heating and cooling equipment, and poor insulation, homeowners are losing hundreds of dollars in energy waste. So at High Performance Energy Solutions, we have made it our mission to create healthy, safe and energy efficient homes. We also strive to deliver an unparalleled customer experience.

The Best Home Energy Solutions Come from the Best Diagnostics

We aren’t just a service company. Like our name suggests, we are in the business of providing solutions. Many, many things affect your home’s energy efficiency. When we come to your home, we look at the whole picture. We have the tools and equipment to test your home’s entire envelope to really see where energy is escaping. From your furnace or air conditioner to your windows to your ducts to your insulation, we’ll show you how to make your home as energy efficient as possible and save you money.

We Are More than Just a Heating and Cooling Company

Our state-of-the-art tools, including the latest and most accurate digital equipment, blower doors, duct testers, etc., will help pinpoint the problem areas and then we can show you your money saving options. Most heating and cooling companies don’t have this level of equipment because they don’t need it. Their business is repairing, installing or maintaining your furnaces, air conditioners and heat pumps.

At High Performance Energy Solutions, our business is making your home as energy efficient as possible. We invest in this equipment because it helps us find the problem areas, assess the potential savings, and ensure happy customers. Because our instruments are more advanced, they help us diagnose equipment faster and more accurately, enhance your system’s performance, and eliminate callbacks.

Heating and Cooling Accounts for Half of Your Home’s Energy Costs

It really is amazing what we can save homeowners on their energy bills with just a few changes to their furnaces and air conditioners, ductwork, and insulation. When you call us, we won’t just repair your heating and cooling equipment quickly and accurately, we will give you cost-effective ideas on how to make your home more energy efficient, saving you hundreds each year.

Let High Performance Energy Solutions fix your furnace and AC and fix your high energy bills while we’re at it. Our goal is to create lifelong relationships with customers who trust us to improve their homes and businesses. Whether you have an air conditioner, furnace, geothermal heat pump, or commercial rooftop unit, High Performance has the experienced service & installation technicians to repair and improve any HVAC equipment. Let us make your home or business healthy, safe, and energy efficient.
