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!
The award winning HB Series raises the bar for water-source heat pump efficiencies, features and application flexibility. Not only does the HB exceed ASHRAE 90.1 efficiencies, but it also uses EarthPure® HFC-410A zero ozone depletion refrigerant, making it an extremely environmentally-friendly option. HB is eligible for additional LEED (Leadership in Energy and Environmental Design) points because of the “green” technology design.
Available in sizes 6 tons (21.1 kW) through 25 tons (87.9 kW) with multiple cabinet configurations, the HB Series offers a wide range of units for most any installation. The HB Series has an extended range refrigerant circuit, capable of ground loop (geothermal) applications (may require optional extended range insulation), ground water (geothermal) applications, as well as water loop (boiler-tower) applications. Standard features are many. Microprocessor controls, galvanized steel cabinet, galvanized steel with epoxy powder coat painted drain pan and TXV refrigerant metering device are just some of the features of the flexible HB Series.
Comfort-Aire/Century’s exclusive double isolation compressor mounting system makes the HB one of the quietest units on the market. Compressors are mounted on specially engineered sound-tested EPDM grommets to a heavy gauge mounting plate, which is further isolated from the cabinet base with rubber grommets for maximized vibration and sound attenuation. The easy access control box and large access panels make installing and maintaining the unit easier than other water-source heat pumps currently in production.
Options such as coated air coil, DDC controls, and dual point power allow customized design solutions. Optional variable frequency fan motor controls or blower motor/ sheave drive packages expand the operating range and help overcome some of the challenges associated with ductwork for retrofit installations. A cupro-nickel water-coil and sound absorbing UltraQuiet package are options that make a great unit even better.
Optional factory installed Waterside Economizer (WSE) uses cool loop water for "free" cooling. WSE option meets IECC section C403.3.1 and is a requirement in many states. WSE requires heat pump thermostat with two stages of cooling and one stage of heating. The HB Series Water-Source Heat Pumps are designed to meet the challenges of today’s HVAC demands with one of the most innovative products available on the market.
