We’ve been providing home comfort solutions for over 45 years!
Launched in June of 2010, ExpressOverstock.com was developed from our experience of over 45 years as an HVAC contractor. We have been buying and selling new and unused overstocked and surplus inventories since 1992—shipping all over the US.
We continue to provide premium-branded HVAC systems, single component products and equipment at the best price to you. Our site is an alternative option for consumers to purchase HVAC equipment at lower prices than most traditional dealers or contractors can provide.
We know that purchasing a new or replacement AC system or component is a considerable investment for you, which is why we’ve geared our site toward helping you feel comfortable in choosing the right system or component at the right price to fit your need.
With our concept, you can experience even greater savings when electing to locate your own professionally trained and licensed technician to help you with your installation and service. We have a growing ANSeRs network of Service Centers who can provide warranty, service and maintenance and installs—ask to see if we have one in your area.
Take advantage of our unique buying position by purchasing your next HVAC system or component from ExpressOverstock.com today!
