Energy-Efficient Heating & Cooling

Is your heater or air conditioner more than 10 years old? It might be time to upgrade. The best time to shop for a new, energy-efficient HVAC product is before your old one completely breaks down. That way you have time to explore your options and compare prices.

Why Upgrade to Efficient HVAC Equipment?

Not only are new systems more streamlined and easier to use, they are held to stricter energy-efficiency guidelines. That means they use less energy and can save you money on your utility bills! Some ENERGY STAR®-qualified heaters and air conditioners can save you up to 30 percent off your annual home energy costs.

Energy-Efficient Furnaces

At Ernst Heating & Cooling, we provide the best service and furnaces, which is why we are a Lennox Premier Dealer.

Energy-Efficient Geothermal Heat Pumps

  • GeoComfort geothermal heat pumps. These systems can use up to 20 to 50 percent less energy than conventional heating and cooling systems.

What Else Can You Do to Make Your HVAC More Energy Efficient?

  • Get seasonal tune-ups. A home’s HVAC system can consume anywhere from 45 to 70 percent of your annual utility usage. Keeping your system well-maintained helps keep that percentage as low as possible. Precision tune-ups from Ernst help keep your system working at its peak efficiency so that you can use less energy and save money.
  • Change air filters every three months. A dirty or clogged air filter makes your system work harder and use more energy. Keep those filters clean, and you’ll save money and have a more comfortable home.
  • Install a programmable thermostat. They customize your home’s temperature to maximize your comfort while saving energy—and money. Learn how programmable thermostats work and which kind is right for you.
