Daniel and his company are beyond excellent! His company, installers, and office staff clearly take the time for their customers and are willing to go the extra mile. I had my 28 yr old gas furnace and air conditioner replaced with new Bryant high efficiency units. I am a very research-oriented individual and consumer who likes to understand and know the details and specifications. This was not a project where exceptions were made. I performed months of research on all aspects of energy efficiency, equipment and manufacturers, and HVAC contractors. After interviewing and obtaining bids from at least 10 HVAC contractors, I narrowed it down to two HVAC contractors. AIS was clearly the best choice for a multitude of reasons:

  • Bryant factory certified dealer (this reassured me b/c I knew AIS would have the most highly trained installers thereby guaranteeing a trouble free installation and years of service. Even the Dept of Energy, Consumer AIS Testimonials Reports, etc., state that the HVAC installation is more important than the brand of equipment.)
  • Diamond certified company
  • Competitive pricing
  • 100% satisfaction guarantee
  • 1st year of service included
  • Honeywell FC100 with MERV 11 filter box and filter included (this is a great air filtration brand and it has been clearly evident in our indoor air quality (IAQ). Honeywell delivers proven IAQ efficiency)
  • Manual J load calculation performed to ensure proper equipment sizing
  • Daniel, the owner, came out to provide the estimate (this meant a lot b/c it showed me that he is not a hands-off owner)

As for specific equipment, I strongly considered having Trane/American Standard equipment installed, but Bryant/Carrier is rated equally strong per Consumer Reports reliability ratings (if I recall correctly, differences of less than or equal to 3% were insignificant). I specifically chose Bryant b/c of the greater availability of part vendors and certified technicians/contractors compared to Trane/American Standard. This was quite important b/c if I ever had equipment problems, I did not want to be with non-functioning units any longer than necessary. And, having great equipment installed by Diamond certified Bryant factory certified technicians left me with no doubts that I should not have any unexpected problems in the foreseeable future. Additionally, it was important that all my equipment (gas furnace, coil, and condenser) were made by the same company. In my case, all 3 were manufactured by Bryant. I did not want a coil made by ADP, which is very common with Trane units. And, the specific Bryant AC condenser I chose was the most efficient (high SEER, EER) and smallest footprint unit compared to Trane units in the same rated efficiency class. This was important given the available space I had for the condenser. I’d like to give a specific thank you to the lead installer Brian and second installer Andrew. They worked so diligently and thoroughly, I was amazed. They were very professional and courteous. I was able to easily sense that they took great pride in their workmanship and ensuring excellent customer service.


And, thank you to the office personnel Giao and Jessica. They were so friendly, polite, and responsive to all my emails and calls, as well as keeping me informed of each step.


Also, it was nice to see the owner Daniel come by during the install. This further showed that he goes the extra mile to ensure his customers are satisfied and the jobs performed by his crews are up to his satisfaction. He is a very involved and an easily reachable owner. He provided a quick reply to all my emails and calls. Thank you for maintaining such high standards for your business and employees, as it shows through in your company’s work. I appreciate your high level of integrity and the quality of work that AIS delivers.
