"I've had ice dams for years. I finally researched it enough to realize it was an insulation problem (I wish I had been smart enough to figure it out sooner). Anyway Speciality Insulation came out and gave me a truly reasonable estimate. The technician found an uninsulated heating pipe, missing batts, in addition to the original find of inadequate insulation. They fixed all of that. I have a room that was perennially cold, it's warm now, no ice dams and I am sure my gas bill will go down. They cleaned up after themselves and were very pleasant people. Very pleasant, efficient and did what they said they could do for an affordable price."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"Overall, Jim and his crew worked efficiently and long hours (7:30 a.m.-4:30 p.m.)  When they couldn't figure out how to manage taking the air handler through the crawl space opening, they called Randy.  It had to be disassembled, which is one of the positive features of the Amana, and then reassembled on spot.

I am very glad that we had the duct cleaning company also do pest control, because the ACI crew discovered hobo and brown recluse spider carcasses in the crawl space, as well as dried cat urine on the visqueen and in the insulation. 

We had not realized how much damage the cat urine had done to the ductwork until the ducts were removed.  There were rusted holes and corrosion streaks throughout the ducts!

The first day was spent mostly by removing the old equipment, which apparently had been installed used and incorrectly, ductwork, visqueen, and insulation. They were very concerned about keeping the house clean and tidy. The second day was spent with the installation of the new components and getting it in working order.  The crew had to come back an extra day, because they lacked the necessary supplies, such as enough visqueen and insulation, to complete the final steps. The entire crew was friendly and answered both my questions and spoke with my husband, via telephone. Very nice, indeed.

Just today, October 20, Jim came back to show me how to work the thermostat because "replace air filter" scrolled across the screen.

Randy, when showing us the possible equipment to be installed, explained the Avista rebate and tax credit that would be available with the purchase of the new equipment.  He is handling the Avista rebate, which is what I call substantial.  We haven't received it yet.  He also worked with us to make replacing the system more affordable. 

As a side note, we did not know at the time of purchase that the seller had purchased the house from a person, who had bought it from a lady who had 13 cats. He flipped the house.  We found this information out from neighbors.  We didn't notice any cat urine smell because each time we visited the house all the windows and doors were wide open; we attributed it to the fact that that was the way the seller liked living.  We have since found urine smell on the walls in many of the closets and near the vents.  We have used Nature's Miracle, which seems be helping. There should be house-fax just like carfax.  I thought that was what inspectors and real estate agents were supposed to do.

All in all, we are glad that the work is done and that ACI did it and that we found them, and other companies, through Angie's List.  Thank you.

Insulation FAQs, answered by experts

Upgrading insulation offers several benefits, including improved energy efficiency, which leads to lower heating and cooling costs. It also enhances indoor comfort by regulating temperature and can provide noise reduction. Additionally, better insulation has a reduced environmental impact and can increase your home's value and overall livability.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency.
