Understanding the Unique Needs of Tiny Homes and Cabins

Tiny homes and cabins are typically between 100 to 400 square feet. This small footprint comes with benefits like lower utility bills, but it also means your HVAC solution needs to be:

• Space-efficient
• Energy-conscious
• Quiet and unobtrusive
• Cost-effective

Key Considerations When Choosing an HVAC System

1. Space Constraints

• Tiny homes often lack the room for traditional ductwork or large systems.
• Opt for compact systems that can be wall-mounted or installed discreetly.

2. Energy Needs

• With limited insulation and exposure to outdoor temperatures, energy efficiency is vital.
• Choose systems with high SEER (Seasonal Energy Efficiency Ratio) ratings.

3. Cost

• Balance upfront cost vs. long-term energy savings.
• Consider installation expenses, maintenance, and lifespan.

4. Climate

• If you live in an area with extreme seasons, you’ll need a solution that handles both heating and cooling efficiently.
