Built on quality and value.
Still is.
API of NH and Delta T opened in 1969 with a straightforward idea: sell heating and cooling equipment that works, and back it with service worth paying for. That has not changed. Our reach has.
We are now part of mSupply, North America's largest HVAC, plumbing and appliance parts distributor. So your local counter comes with a nationwide network behind it. A full parts catalog, same-day shipping, and next-day delivery to 93% of the U.S.
We remain a Master Distributor for Rheem's premier HVAC lines. The equipment we sell heats and cools homes, restaurants and retail centers across New England.
We also stock the efficient end of the market. Hydronic heating, geothermal, solar. Product lines that pull less electricity and keep saving your customer money year after year.
THE API ADVANTAGE
Four reasons contractors keep coming back.
Quality products and people who answer the phone. Plus hydronics and sheet metal fabrication under our own roof, so you are not chasing three vendors for one job.
Certified Technical Support
System design, application, heat load calculations. Our certified team works the problem with you, before you order the wrong equipment.
Same-Day Quotes
You need a number to win the bid. You get one the same day, not next week.
On-Demand Delivery
Nearly 20 company-owned vehicles. Same-day residential and jobsite delivery, on demand.
Training
Technical, business and sales classes twice a year, taught by industry experts and our own trainers. When you are better, we are better.
OUR PEOPLE
The people behind the counter.
We see every customer as a partner. These are some of the people who made that real.
