TLDR: High Quality, Professional, Excellent Value. Highly recommend. I called Koala for a quote to add insulation in my attic due to high AC bills. Bill Villani came out and did a thorough inspection and evaluation of my home, existing insulation levels, asked about hotspots in the house and even asked how long I intended to stay in my home. He recommended several options, including sealing of ducts and ventilation options as well as handling the SRP rebates. I ended up going with Koala beca

Koala insulation completed our home attic insulation upgrade recently and we are extremely satisfied with the price and quality of work. We were able to take advantage of two SRP energy efficiency rebates which reduced our cost significantly. The real test will be a comparison of last years summer cooling bills with this summers upcoming bills but we are confident we will see improvement. Work was completed quickly and post work cleanup was done e nicely. Before and after photos included.

Bill inspected my attic space and discovered that my AC unit was blowing cool air into the attic from a torn seam. He demanded to come back the next day and repair it at no cost. Because of this action, we selected Koala Insulation for our job. After discussing our options we elected to use foam. The owners Bill and Jim were very professional in completing the work. I highly recommend them.

I want to express my respect and appreciation for Bill Villani and Koala Insulation of the East Valley. After hearing their radio show on how attic performance affects home energy use, I scheduled their free attic evaluation for a home I had just purchased. With a background in building energy performance, I found their explanations on the show to be grounded in solid, proven science. Based on what I expected to find, I assumed Bill’s inspection would lead to a proposal for a few thousand dolla

Upon hearing from my HVAC company that I needed insulation and duct replacement at a very high cost; I decided for a second opinion. I decided to go directly to an installer to get a second opinion and compare pricing. WOW is all I can say! Not only did I NOT need any duct work, the pricing for the insulation job was a third of the price! Koala had 5 star reviews and completed the job quickly, efficiently and left my home spotless. From the first time I contacted them to completion, the process

We just had spray foam insulation done, and I can honestly say we’re so glad we did it. After getting a few quotes, we chose Koala Insulation because of their great reviews and how easy and knowledgeable Jim (one of the owners) was to talk to. Their price was right in line with the others, but their professionalism and expertise stood out. Our attic was a bit tricky, but they handled it really well—from the insulation removal to the final spray foam, they took great care of everything. Even bet

If I could give 10 stars I would! We hired them to remove all of the old batt and blown in insulation in the attic space of our 50 year old home. Everyone that I interacted with at Koala provided the utmost of customer care. This includes Jim (one of the owners), office staff and the work crews. When Jim and I walked our home to review the work he provided solid suggestions or solutions that made sense. While their pricing was not the lowest as compared to another bidder I felt that they gave u

I wanted to increase the insulation in my attic so I made appointments with five SRP approved contractors. I could have stopped with Koala. Everything I can say about them is 5 Stars. Prompt, everyone was super friendly, No high pressure and fair priced. They did a great job. From Fernanda in the office to Bill and his brother and Kevin and Ryan, these folks just try harder to be the best.
