"The installers were professional and courteous, they cleaned up after themselves and left my home in the same condition as when they arrived. The blown-in insulation has made a noticeable improvement over the temperature on our 2nd floor."

"I called Evergreen Electric and setup an appointment for the next day to perform what I figured would be a couple small jobs and to receive an estimate to run cable into new rooms. The original appointment was delayed because of a power outage on another job, but speaking to Josh on the phone, he was willing to come by as soon as he was finished even though it would have been well into the evening. I told him the following day would work fine and we rescheduled the appointment.
Josh arrived the next day and examined our situation. Our house is nearly 40 years old and it turns out the problems were much deeper than I thought. Josh crawled into the attic and rewired the junction boxes that were not just loose but had previously been wired incorrectly. He also spent well over an hour attempting to diagnose why our breaker was tripping without much of a load on it. He was very thorough in his troubleshooting. He replaced the breaker with a higher amp version and the problem is fixed, but he also indicated there is likely more faulty wiring running through the attic buried under the insulation and someone should come back to assess the entire electrical system.
Josh was very courteous and professional and answered all of my questions. After spending about 2.5 hours with us, I was expecting a large bill. I was very pleased when he told me he would only be billing me for one hour.
About 30 minutes after he left, we noticed that a light in the hallway would not turn off. I called to report it and Evergreen responded immediately. Josh came back right away and fixed the problem. He even replaced the light switch free of charge. It is nice to see a company that stands by its work and acts so quickly when something is wrong.
I would highly recommend Evergreen Electric. They are prompt, thorough, and stand by their work.

"I think they did it all in one day. When we decided to go with them. We have one room that doesn't have a second story with recess lights. That room is fairly new, we put it in 6 years ago. He showed me pictures of stucco in there. All those lights were coming in through those recess lights, they were not properly caulked or insulated, so we were losing a lot of beautiful energy through those recess lights. He corrected that. He correct where some of the baffles were covered. He brought it up to high lighting. There was a giant antenna laying across the top of the attic in the main house doing absolutely nothing. They broke it up and removed it. I felt like they were my eyes and ears going up there, something I couldn't do and showed me things that were done incorrectly.  The original insulation was a bluff. It had been displaced. I actually had ceiling drywall in between the structure. They corrected it all. Even the ceiling access was properly insulated and closed. They are just very thorough. They helped us when they troubleshooted from the old company. The price seemed perfectly fair, they didn't try to sell you a cheap product with a cheap price. It seemed like a fair price in line with quality. That's all we really want."

"Expect for them to be on time, that they will cover the floors, that a window may be opened for an extended period if adding
insulation.  There will be loud noise if adding insulation so be prepared.  Find a comfortable place to be while the
work is being performed if you are waiting at the house.

Insulation questions, answered by experts

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.

The amount of insulation you need will vary depending on where you live. Energy Star recommends certain minimum insulation values in different geographic regions. In most cases, however, even adding a little insulation is better than not adding any.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
