All Iowa Insulation Services

John and his employee did a fantastic job blowing insulation into the walls and attic of our 118 year old home! Our downstairs has central HVAC but the upstairs does not; prior to adding the new insulation our bedroom would sometimes get down to 35⁰ in the winter if the wind was blowing from the south or west. The electric radiant wall heater could not keep the bedroom warm, and even though we had added extra insulation ourselves in years past it simply wasn't enough. The day AIIS blew in the insulation it was windy and 37⁰ out dropped to low 30s overnight; however, that night - with no heater running in our bedroom - the temperature in the room stayed between 70⁰ and 74⁰ all night! They were very friendly and professional and worked quickly but efficiently. They did a great job cleaning everything up when they were done, the price was affordable and I would not hesitate to hire AIIS again! They are the best!
