I recently contacted Infinity Air to replace the 32 year old HVAC system in my home. I called at around 2:30 PM on a Tuesday and Doug came out the same day to assess my situation. I had estimates in my hands less than 3 hours later, and Doug answered a couple of additional questions that weren't covered in our initial assessment. I accepted one of the estimates, and the service appoint was made for Friday at 8:00 AM. They arrived promptly, and my new system (complete replacement) was in and running by 2:00. They cleaned up completely, and did an excellent job of installation and of keeping me informed on their progress. Highly recommended.
