If you have an ancient type of HVAC air conditioner/heater that needs parts, Morin Distribution is probably a good starting point. The plumber wanted to upcharge me over double what the part actually costs, but Morin was able to ship it directly to me without issue saving me about $ 600! Sherie was incredibly helpful over e-mail, making sure the correct part was ordered. And if you wanted to save even more money, you can pick up your order at their warehouse, thus saving on shipping costs. Now my A/C is working like new(new being 1980, when the A/C was first installed)!
