About H-Mac Systems

Founded in 2003

H-Mac Systems was established in 2003 to serve as a reliable source for commercial/industrial HVAC equipment and parts. We started in a modest, windowless office with a handful of manufacturers and a strong desire to make a contribution to the Heating, Ventilating, and Air Conditioning industry.

Today we are one of the country’s leading e-commerce HVAC distributors, stocking thousands of name-brand products in our purpose-built office/warehouse facility located in Southborough, Massachusetts.

Since the beginning in 2003, customer focus has driven everything we do. We are always working to provide better value through our broad offering of HVAC equipment and parts (over 400,000 and counting), easy-to-find detailed product info, simple ordering process, clear and consistent status updates, and streamlined support systems. All available online 24 hours a day, 7 days a week.

Quality HVAC Products in Stock

H-Mac Systems offers convenient, one-stop shopping for all your HVAC equipment and components. Our selection of high-quality, heavy-duty products is unmatched in the industry, and we only work with reputable manufacturers who stand behind their products.

We keep thousands of popular products in our warehouse so we can ship quickly – usually same day! All of our items are new; no factory seconds or refurbished items. H-Mac Systems is factory-authorized, and we have long-standing relationships with suppliers to get our orders filled quickly.

We continually update product availability to give you the latest information. If a product is not in stock, we provide an accurate estimate of when to expect it so you can plan accordingly.

Save on Your HVAC products

Because we buy in bulk to keep our warehouse fully stocked, we’re able to negotiate the best prices with our suppliers and pass that savings along to you.

We’re also continually monitoring the industry to make sure our prices are extremely competitive. If you’re buying a large quantity of an item from us, ask us for a volume discount.

Fast, Free Shipping on ALL products

We have thousands of products in stock and ready to ship, with expedited (next day and second day air) shipping available for most items. We offer free ground shipping on all products – no minimum purchase, no exclusions – to any of the lower 48 states. And you can always check your order’s status right on our website.

Items shipped from our warehouse are securely packaged and double-boxed to reduce the chance of shipping damage. If you ever receive a damaged, defective or incorrect item (we try extremely hard to make sure these things do not happen!) we will work with you to quickly resolve the issue.

All the Information You Need

We believe informed customers make the best decisions. For that reason, we publish a wealth of information about each of our products right on our website, so it’s available to you 24/7. Search for any product and you’ll find important details such as:

  • Competitive pricing
  • Product availability / lead times
  • Ship-from location
  • Expedited shipping choices
  • Compatible options and accessories
  • Clear photos, often multiple views
  • Links to product literature: catalogs, submittals, manuals

Once you place your order, it is screened by our experienced engineers for inconsistencies. Many potential issues are caught and prevented before shipment, saving you time and money.
