NASA Heating and Cooling did an outstanding job of helping me with the procurement, and installation of a new Air Conditioner. The NASA Team is highly knowledgeable, deeply experienced, and very customer-oriented. They were highly recommended from a friend, and did a stellar job of exceeding all of my expectations on all fronts. I am eagerly looking forward to working with the NASA Team for all of my future Air Conditioning, Heating, and Hot Water Rental needs. What differentiates NASA from other organizations is their unmatchable customer-orientation, deep expertise, and high responsiveness. Mr. Amit Gupta, leads this terrific organization, and goes out of his way to ensure his team delivers everything which was promised, and even more. For example, Mr. Gupta didn't charge for extra material, which was required as my house size is relatively larger compared to others in my neighbourhood. NASA's quotation was the lowest among 6 suppliers I had considered, and they delivered on budget, and on time. Unlike other organizations, NASA doesn't cut corners to make extra profit, and delivers the best quality. Mr. Gupta himself is a highly qualified engineer, and is a veteran in this industry. Mr. Gupta can accurately, and quickly diagnose the root cause of an issue, which is key to troubleshooting it in a timely and cost effective manner. He has built a high performing team - nimble and responsive in troubleshooting issues in a timely manner, which is a critical requirement, when an A/C or Furnace fails. Last but not the least, NASA provide an outstanding after sale service support. I highly recommend without any hesitation NASA Heating for all your A/C, Furnace, and Hot Water Rental needs.
