After doing a good research, I found Smart Air Electrical prices the most competitive. The team presented good options depending on my budget so I ended up getting the Teco System with a 7 year warranty. The low price range was most attractive. It was also good to get 10% discount as well- so I saved another $900. The crew that installed the AC were very professional. They spent the whole day in my house and were very respectful. I am now enjoying cool air.
