Spacepak – High Velocity Heating System

If you want to improve your home’s existing central heating and air conditioning system without ripping up your walls and adding new ductwork or unsightly chase boxes, consider upgrading to the future of heating and air conditioning technology – the Spacepak. With the Spacepak, concerns about removing walls and ceilings or other complex install jobs common to central heating and air conditioning installation are a thing of the past – the only thing Spacepak requires to operate are small two inch flexible tubes that can be threaded cleanly through your existing wall gaps, ceilings and floors to reach every room. If you’re ready to install one of the world’s most advanced central heating and air conditioning systems in your Maryland (MD) or Washington, DC home, call Michael Bonsby HVAC today!

Spacepak – a Revolution in Central Heating and Air Conditioning

First pioneered nearly 70 years ago, The Spacepak central heating and air conditioning system uses a high pressure forced air delivery system that is designed to provide both central heating and cooling throughout your entire house. Continued improvements to the technology have created a system about half the size of a traditional central heating and air conditioning system that uses a specially designed air handling unit which generates high pressure air and forces it through small diameter ducts. A small rectangular or round supply duct serves as the main supply duct and supplies air to flexible, insulated feeder ducts. The air then passes through soundproof tubes before entering the room via a small plastic plate.

A Comfortable Heating and Air Conditioning system

Working on the principle of “aspiration”, the Spacepak is able to deliver the best comfort of any type of central heating and air conditioning system. Aspiration, which involves using a high velocity air stream to gently mix with the air already in the room, provides uniform heating or cooling and virtually eliminates drafts as well as hot and cold spots.

In addition to comfortable, even heating, the Spacepak central heating system’s unique cooling method and exclusive deep coil design removes 30% more of the relative humidity from the air than traditional central heating and air conditioning systems, keeping you cooler even during the hottest, most humid summer days. The highly effective and efficient humidity controls make the Spacepak central heating and air conditioning system a perfect addition to any older home or historic property, protecting antique furnishings and fixtures from damage. Other ideal applications for the Spacepak central heating and air conditioning system include homes with baseboard hot water heating, steam or electric radiant heating, or new homes with in-floor radiant heat.

If you are ready to install one of the world’s most advanced central heating and air conditioning systems in your Maryland (MD) or Washington, DC home, call Michael Bonsby HVAC today and ask about the Spacepak central heating and air conditioning system. We can install your heating and air conditioning system today, so you can start experiencing maximum comfort right away!
