Awhile back, I had a termite inspection and the guy who crawled under my house mentioned that some of my 55-year-old duct work was rusted and he saw a couple of small holes in it. No wonder my gas bill was so high. I called a couple of places for estimates and chose All-Temp because the price seemed very reasonable and they were able to do the job during a convenient time for me. Well, Mike and his partner came everyday for a week and worked until it was done. They did a great job, sometimes under very difficult conditions(narrow crawl space). Now my house is toasty warm and I’m not heating the neighborhood!
