I had Day & Night come out to assess our AC when it went out for the fifth time in 2 years. After the warranty company kept trying to fix it over a week, I called Day & Night and they were very quick to get an estimate as well as get it installed within days. Over the past 2 years there were several small issues with our brand new Trane AC, installed by Day & Night. After the fourth time the unit broke down, Day & Night replaced the entire unit. I am not pleased that the new unit broke down so many times, but Day & Night had exceptional customer service in honoring their new unit and repairs.
