Recent Review: After a complete assessment of my 13 year old outside broken air conditioner unit, (furnace, and duct work located in crawl space) under house, I asked for a quotation for repairs and new replacement with several levels of Seer rating. Scott took the time to show me his observations in detail, explain the options, and benefits of each choice, along with expected utility savings. I was somewhat surprised at the total cost for the high end system, but it was not too far out of what I could find on the internet. ( It was rather difficult to get competitive cost information without multiple quotes). The fact that I wanted the best filtration system available ($1500 extra) plus major duct work modifications were necessary to get two zones (with dual thermostats) added to costs. I also got the best available control systems with internet features, and the two zone thermostats synchronize with each other. I am very pleased with the planning, scheduling, installation, and follow up of Scott Walker Heating and Cooling. Still waiting to get my first utility bill, which will take a year to fully realize accurate savings with the new system. I have dealt with various types of contractors in industrial settings for over 30 years and I was very comfortable with the capabilities and performance of this contractor.
