Design Air Inc — Heating and Air Conditioning in New City, NY

Allow us to introduce ourselves. Design Air Inc is a locally–operated full service HVAC company. We are located in Hillburn, NY, one minute past Suffern, and service Rockland, Westchester, Orange and North Bergen Counties. We’re proud to offer some of the area’s finest heating, cooling and indoor air quality products, with prompt and professional customer service. Regardless of the season or the temperature outside, we can make your home feel perfectly comfortable.

Part of the reason that customers choose us is our reliable 24–hour emergency repair service. If your system ever goes down we will have someone sent to your home ASAP to repair it. The majority of our competitors don’t take on the added expense of offering 24 hour emergency service, and because we have a large home base fully–stocked with replacement parts, we can repair most HVAC systems on the spot.

We’ve had the same owner since we started over 25 years ago, so you know that you aren’t hiring a company owned by a giant corporation that has to answer to stock holder. We are a local company run by a man who knows that honesty, integrity, and customer service is our future. In fact, the majority of the management team has been with the company for over 20 years, and all of our staff, including managers, are available to speak to our customers and help them out with whatever they need.

To further prove our dedication to quality service, here are a few of the major industry awards we’ve received:

  • Lennox ’Centurian Award’ – Top 100 Dealer in District – Specifically in customer service & Quality Installation
  • Angie’s List – Superior Service Award (2012)
  • BBB – Accredited Business – Link to BBB Design Air Inc Reviews
