This is a question that we get frequently. RHI Supply sells only to Mechanical Contractors that are in the business. If you need a part most likely we will inform you if it's available. Then we will direct you to your HVAC Contractor. That way you get the part you need, installed correctly with the full factory warranty.

Only if you are a licensed HVAC contractor. If we are unfamiliar with you we may ask for supporting documentation. If you are not a licensed HVAC contractor we’d be happy to help you find someone in your area who is able to purchase parts or equipment in your area.

Yes! Our online store makes it convenient for businesses with accounts to order any time of the day or night. Go to

We do not offer online sales to the general public (see question #1).

You will be able to see your pricing, see our stock levels live, place orders and handle accounting needs at our website.

Absolutely! Locating odd or hard to find parts is one of our specialties. We may also be able to find you generic options that may be less expensive, more readily available or both!

We have an emergency phone number for each store and we actually answer it! These phone numbers are listed on our Contact Us page. We can meet you at one of our locations to get you the products you need to get up and running. An after hour fee applies.

You can send it back with your delivery driver or salesman. Or you can send it back to your local RHI Supply location. We’ll need to know if you just didn’t need it or if it’s warranty. If we need more information or if any special charges will apply to your return we’ll contact you.
