Blue Air is great! In addition to doing a great job with the actual installation of my furnace, they followed through with every single thing they promised. They said that they were going to be there at 8:00am, and they were. They said that they were going to e-mail me a copy of the warranty, and they did. They were on-time, courteous, and did it all at a competitive price. That kind of dedication and follow-through goes a long way with customer service. I highly recommend Blue Air! I wrote the above paragraph 8 years ago, and I just wanted to amend it. I recently used BlueAir to install a full HVAC system in my new house two years ago. Since the installation, I have had to rely on BlueAir for some follow-up work. Both Marianna and Mark have been extremely accommodating, and follow through to ensure that their customers are satisfied. Marianna even took my phone call after hours when I needed to speak with her. Thanks for the great customer service!
