The short story: I recommend Cold Craft. I had a great experience with Cold Craft for removing and replacing a furnace in a residential (3BR/2BA) home. The long story: Tenants in my 3BR/2BA rental reported the home's 40 year-old furnace had basically fallen apart. I called around to a few HVAC repair/replace outfits, including Cold Craft. (I used the Yellow Pages; I did not have any recommendations or references.) After talking to Steve at Cold Craft, I somehow got a better feeling of competence than other operations. Cold Craft came out for an inspection. Emiliano and Roy were on time (early, actually). They confirmed the old furnace's death, explaining its multiple problems and deficits. They gathered measurements and details, and explained options, recommendations, etc. They were clear, and did not pressure me. I received an email the next day with a detailed estimate. I arranged a schedule with Steve. I was glad to see Emiliano and Roy again (and on time again) to do the installation. They finished the installation within their estimated time. Their finished work is clean and professional; they cleaned the furnace closet; and they cleaned up after themselves. They explained the new furnace operations, maintenance, warranties, etc. What more could I ask? Kent Penning (president) included a feedback form with the paperwork, indicating he cares about customer satisfaction. (And with all of us on Yelp and the Web, I think Kent's strategy is wise.) All in all I had a surprisingly pleasant experience with Cold Craft. (I wish I could say the same for dozens of other contractors I deal with!) I think Cold Craft pricing is reasonable and competitive. Sure, I could have shopped more and saved a few bucks, but my satisfaction is worth a lot more than that.
