Upon excellent reviews I called Service Wizard to diagnose, fix or replace a furnace that was not working. We were having our first winter freeze during the holidays. We had no heat. I called Friday morning, they arrived Friday afternoon after texting/calling me to alert me of their arrival. They even showed a picture of the person who would be arriving to assess the problem. After inspection, we were presented with our options, from the least expensive to the most expensive. ALL my questions were answered, Terry was professional, trustworthy, and down-to-earth. I have never felt, when hiring a professional for anything, more comfortable with or so right about my decision to hire this company. They did not "try" to do a service or sell me a product I did not need. The work was done on Monday. Voila! They laid down a runway so as not to track anything on to my floor. When they were done, they brought in their own vacuum cleaner to make sure the area was clean. Their estimation of time to do the job was right on t he mark. I will never hire another company for any problem that falls within the scope of their business.
