We are a GREEN Quality Driven company with highest precedence set on customer service. Nate certified, BPI certified, licensed and insured. 100% quality service promise. We have a price match guarantee (must be "apples to apples"). Our quality is the highest in the area. Ask us how we can help you with all of your HVAC needs.

"Paid more than 20k for a brand new system that included a 2 year maintanence warranty from Feb 2023. In April my unit broke and had no a/c in 2023, and they continued to blow my repair requests off until june. Also, for some reason they claim the maintenance warranty is expired as of Feb 2024. Simple math would detirmine that the warranty expires in 2025, but with our repeated emails, they continue to say it is expired. And now there is another issue and it is only the 2nd year having their unit in the house. I would not recommend them to anyone."

Take the first step in doing your part today!!

"I complained twice and they had to come back out twice because they didn't apply the insulation as thick as I paid for. I assume because they were angry about coming back out they covered up two of my vents so I can't attach the pipes to them. I can't even find the ends. I will need to dig the expensive foam out to find them."

We're a refreshingly different kind of company. We take a "whole house" approach to find the best, most efficient energy savings in your home or small business. Focused on quality, "energy saving" spray foam, insulation, and weatherization, we act as a consultant and gateway to your largest energy savings.

"We hired Performance Energy to air seal our attic and add additional insulation. Their representative provided a clear explanation of their process and provided a thorough assessment of our home's energy concerns. I had already done a lot to the house, so I was pleased to have a second set of eyes evaluating my work. They arrived with a crew of four, three were in the attic for several hours sealing all the gaps and cracks between the attic and the living space. They also used a thermal camera to check for leaks in my HVAC ductwork that was in the attic - prior to insulating. Once all the sealing was complete, they proceeded to add additional insulation throughout the attic. The only snafu was their generator died. We looked at the electrical connections and found the brushes in the motor had overheated and melted. It took about an hour to get a replacement generator and they were able to finish the project. Other than the generator - things went smoothly. I would definitely recommend them if you want to make your house more energy efficient. Don't add extra insulation until you have air-sealed!!"

Energy Efficiency Auditing questions, answered by experts

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems.
