I had King Insulation come out for an estimate on new insulation on my old attic. Steve was incredibly helpful, informative and polite. He suggested I do an energy audit and referred me to another great company - AZ New Image. Long story short I ended up getting a packaged deal on new insulation, duct sealing, air sealing, new A/C duct work and upgraded energy-efficient canned lights. Throughout the whole process they worked with me and answered all my questions, no matter how many phone calls it took. Not only did they literally work around our holiday schedule - blowing in the insulation on New Year's Day - but they even submitted the SRP rebates for me, which I received about a week later.
As great as that experience was, King Insulation just re-blew the insulation for me over a patio ceiling that had collapsed due to previous (unknown) water damage. No hassles, no negotiating or trying to get extra money from me. They recognized the unfortunate accident and helped me out when I really needed to catch a break. On top of all that they were able to come out and do the work on the same day that I called. That's probably not typical so I know I got lucky, but it was great to be able to call and get immediate response and results.
I highly recommend King Insulation and their partner companies for anything in your home that needs to be more energy efficient.
