As New Hampshire residents, we’re lucky enough to experience all four distinct seasons – ranging from bitterly cold winters to hot and humid summers. While we can usually get by with opening the windows during the shoulder months, having an efficient HVAC system is critical to maintaining health and comfort all year round. Luckily, the heating and cooling experts at Heritage can make sure you and your family are comfortable indoors, no matter what mother nature has in store.
Our trusted team of cooling specialists are trained to work on almost all residential AC systems and are backed by a wealth of experience from our 35+ years in the industry. Whether it’s unexpected AC repairs or routine air conditioner maintenance, Heritage has technicians available to help in your area.

Mitsubishi Air Conditioners
Don’t have existing ductwork? Ductless air conditioning may be a good option for you! As a Mitsubishi ductless Diamond Dealer, Heritage can expertly design a system unique to your home and needs and can provide you with a number of solutions to bring cooling where you want it. As a bonus, every Mitsubishi ductless unit also functions as a heat pump (essentially an AC system in reverse) during the colder months, and if you upgrade to a Hyper Heat unit, you can heat your home all year round, even down to -13°F.
