Since our inception back in 1969, API of NH & Delta T has prided itself on delivering not only quality services you can depend on but also the best value in heating and cooling products.

We are proud that Rheem Manufacturing selected API of NH as the Master Distributor of its premier HVAC product lines and is now distributed to many of our professional contractors.
