If you own a home in Denver or the surrounding area in Colorado, an energy audit with E3 Power is the first step on the path towards:

  • Increased indoor comfort

  • Higher energy efficiency

  • Lower heating and cooling costs

  • Healthier indoor air quality

During our home energy audits, e3 Power uses a variety of high-tech, state-of-the-art tools and instruments to identify the key areas where your home is wasting energy. Included in our audit reports are our recommendations for the most cost-effective ways to improve energy efficiency, comfort, and indoor air quality.

Why e3 Power Home Energy Audits Are Better

What sets e3 Power apart from the other Colorado companies offering energy audit services near you?

1. Our independence

e3 Power doesn’t offer any of the home performance services that most other energy audit contractors do. With our team, you’re getting a truly independent, unbiased home analysis.

Too often, subpar contractors use energy audits as a sales tactic to upsell you on services you don’t actually need. At e3 Power, you can trust that if we recommend adding more attic insulation or sealing your ducts, we actually believe the upgrades are in your best interest!

2. Our building science expertise

We take pride in the long list of certifications and training our team has! From the Building Performance Institute to RESNET, PHIUS, ENERGY STAR®, and much more, the auditors at e3 Power are true building scientists who know what they’re talking about when it comes to home performance.

3. Our experience

Over the years, our team has conducted more than 1,500 energy audits, 5,000 blower door tests, and 500 duct blast tests throughout Colorado. We know the unique ways in which the local climate can affect homes, and we can help you uncover the underlying issues in your home quickly and professionally.

Why Energy Audits Are So Important

Many homeowners wonder if energy audits are worth it, and some decide to skip an audit and go straight to making home improvements themselves. At e3 Power, we’ve seen plenty of instances in which what first looked like an easy fix turned out to be more complex, and the homeowner wasted time and money on services that could have been avoided if an audit had been completed first.

A home energy audit for your Denver home gives you real insight into your home’s energy use, so you can uncover the actual problem and find the right solution for your house. To learn more about the impact energy audits can have on your home read through our blogs

What to Expect During a Home Energy Audit from e3 Power

Our approach in conducting home energy audits is to take a comprehensive, whole-house assessment of the home, which distinguishes our "whole-house energy audit" from the free "clipboard audits" offered by many utilities, box stores, and companies that offer a discounted home energy audit as a means to sell products or services.

Our whole-house energy audits look at:

  • The building envelope (all the components that make up your home's outer shell, including windows, doors, insulation levels, and the level of air leakage in between building materials)

  • All combustion equipment including boilers, furnaces, and water heaters

  • The movement of air within the home to ensure that the air you and your family are breathing is fresh, healthy, and safe

During your Denver energy audit, we’ll use an infrared camera to identify air leakage and deficient insulation, a blower door to measure the rate of air infiltration in the home, and a duct blaster test to determine whether your ducts are well sealed, among other tools. 

We also offer drone-based home & commercial building thermal inspections, which can help get to the bottom of particularly complex energy issues in a home. Learn how to prepare for your energy audit here
