Improving home performance and energy efficiency for our customers.

Energy efficiency has long been a focus for homeowners and contractors alike. In a changing world, the importance of home performance is only increasing with time, and at Greiner, we stress this to each and every customer we serve. Improving home performance is one of our primary goals with every project we take on, which is why we offer energy upgrades that can help take your home's energy efficiency to the next level.

The Benefits of Energy Upgrades with Greiner

At Greiner, we work hard to assist our customers in taking steps toward an energy efficient future. Making energy upgrades to your home such as those outlined above includes a number of benefits:

  • Lower energy bills
  • Longer duration of systems life
  • Improved home comfort
  • Safer, cleaner indoor air
  • Reduced impact on the environment

Your home is a complex system. We understand it, inside and out.

Home performance is not unlike the human body or an automobile. When everything is running smoothly, the overall system functions as it should. Should one thing go wrong, however, everything is affected. Keeping all aspects of home performance operating at their peak is essential for your home to function properly as a system, and it all starts with a home energy audit.

Increase your home comfort year-round with high-performance insulation.

At the end of the day, there’s nothing more important than being able to come home to a comfortable living space. California summers can be overwhelmingly hot, and no one wants to be chilly on a cold winter’s night in their own home. In both scenarios, indoor comfort levels can often come down to whether or not your home is properly insulated.

When was the last time you took a moment to consider the quality of your home's ductwork? Duct systems are considered to be among the most often overlooked aspects of a home, yet the role they play is undeniable. Think of your home's ductwork as its lungs. When things are clear, clean and well-designed, you've got nothing to worry about. Not all ductwork is created equal, however, and over time, duct systems can become dirty and loaded with dust and other contaminants.

Boost comfort and save energy!

Plus, we'll help you get up to $6,500 in home efficiency upgrades.
