Our Company

Our Family Serving Yours, For Over 70 Years!

Climate Design Systems, originally founded in 1946 under the name of Haverhill Sheet Metal, is a full-service heating, air conditioning and indoor air quality contractor. We are locally owned and managed by some of the most experienced HVAC specialists in the Northeast.

We always take the time to educate our clients on guidelines, new and old, that need to be followed. As a green company, we are concerned with preserving our environment and inform our clients of local and federal funding available when they install systems that are energy efficient. Our Design Build Division always takes into consideration rebates from local utilities when designing mechanical systems.

All of our engineers and technicians are fully certified and trained. We have a staff of 150+ employees and maintain a fleet of 75 digitally-dispatched service vehicles equipped with the parts needed for a majority of repairs. Our staff keeps up with the latest in heating and air conditioning technology and is ready 24/7 to help with all of your home comfort needs!
