I had AC/Heating issues with my upstairs system. The first company that came out, at a cost, evaluated the issue(s) and diagnosed it as a bad evaporator coil. The replacement cost quoted was out of this world ! I surfed the internet and stumbled on Total Air, read their impressive reviews (praising Nichole all the way), so I decided to give Nichole a call. She immediately sent out a technician to evaluate the issue (at no cost, yes at no cost). The next two days the coil was replaced to my ULTIMATE SATISFACTION for 65% of the cost quoted by the first vendor!!
