SpacePak Air-to-Water Heat Pump

ZonePak is the smart, efficient way to deliver customized comfort throughout your space. Using a unique air-driven damper system controlled by multiple independent, pre-programmed thermostats, ZonePak creates up to three separate comfort zones—all from a single air handler.

By directing conditioned air only where it’s needed, ZonePak helps each thermostat reach its set temperature faster. This targeted airflow improves air-handler efficiency and reduces overall energy use, lowering operating costs while maximizing comfort.

How Does SpacePak Work?

SpacePak is a high-efficiency, small-duct heating and cooling system designed to deliver superior comfort where traditional HVAC systems fall short. Instead of relying on large, bulky ductwork, SpacePak uses compact, flexible, pre-insulated tubing to distribute air evenly and quietly throughout the home.

1. High-Velocity Air Delivery

SpacePak pushes conditioned air through small, 2-inch outlets at a higher velocity than standard duct systems. This creates a gentle mixing effect in each room, known as aspiration, which eliminates hot and cold spots and maintains a consistent, even temperature everywhere.

2. SpacePak’s Small-Duct Network

Flexible mini-ducts snake easily through walls, ceilings, closets, and tight spaces—making SpacePak ideal for:

  • Older homes with no existing ductwork

  • Remodels and retrofits

  • High-end homes where aesthetics matter

  • Properties with limited mechanical room space

Because the ducts are so small, installation requires far less demolition than traditional HVAC systems.

3. Central Air Handler

At the heart of the system is a compact air handler, which connects to the small-duct network. It conditions and delivers air with enhanced efficiency and very quiet operation. The air handler can be paired with:

  • Heat pumps

  • Air conditioners

  • Boilers

  • Furnaces

  • Hydronic coils

This flexibility makes SpacePak one of the most adaptable HVAC solutions on the market.

4. Zoning Capability (with ZonePak)

When paired with ZonePak, the system can divide the home into 2–3 independently controlled zones. Each zone has its own thermostat and air-driven dampers, allowing you to individually adjust temperatures across different areas of the home—maximizing comfort and reducing energy use.

5. Energy Efficiency

SpacePak uses less energy by:

  • Eliminating temperature fluctuations

  • Moving air more efficiently

  • Reducing run time

  • Targeting only the zones that need conditioning

This means lower energy bills, longer equipment life, and better performance year-round.

6. Quiet, Invisible Comfort

With small outlets that blend into ceilings, floors, or walls and ductwork hidden behind the surfaces, SpacePak delivers comfort without changing the look of your home. The system operates quietly—no loud vents, no drafty blasts of air.

Joseph knew exactly what I needed for our space and use. He was incredibly knowledgeable to help us get the best and most efficient units to fit our needs and budget! He and the install team were quick and easy and we have been happy with everything sinc

jonathan Goldberg

I finally had to write a review as the arctic freeze has blanketed us for the past days – sub zero temperatures! The two mini-split systems installed by Joseph have been working quietly and effectively keeping us warm and cozy. The installation went as planned and Joseph gave us options on interior and exterior finishes and where the systems should be affixed and piping run. I believe, the evening he got back to his shop after our project was complete, he submitted the rebate forms!! We got our rebate within 30 days – which is quite amazing. He and his associate, Lev, worked like a well orchestrated team. Joseph has been available for follow-up questions and is prompt and thorough in his replies. It feels good as a consumer to work with a company that is run by, and hires mechanics that are kind, competent and good people! We have recommended their services to family, and will certainly call them for our next project.

Joseph was a consummate professional. My photo studio in Denver has been without AC and heat for years and this June I’d had enough and found Joseph on Google. He gave his professional opinion on placement and size of the mini-split unit, so I didn’t have to worry about that. My studio space is unique and old (1930s home) so he was able to work around those challenges and everything turned out beautifully. Joseph books up fast so hire him if he’s available!

Angie Birky

We’ve had the system installed for about a month and I am over the moon happy with it. As a longtime swamp cooler user, the switch has been amazing because I was so tired of feeling the dampness in my home. Joseph was incredibly responsive, thorough in his assessment, quick to install, and did wonderful work—at a great price! I would highly recommend working with him. For reference, my home is about 1100 ft.² and I installed two units upstairs and one unit in my basement.
