## What makes Unico the best choice for older homes?
###### Ideal for historic homes. Small ducts fit in most homes without major renovations. Air supply tubing is flexible and can be inserted into existing tight spaces. This makes mini ducts the best choice for historic or older homes where you want to maintain the home’s character and want your heating system to have minimal visual impact.
No more dry air. With a small duct heating system from Unico, you can say goodbye to dry skin and air that comes with other heating systems. The Unico System is a closed system that warms air from within your home without drying it out. It’s not just comfort – the humidity also keeps your family healthy. No more dry air means you can say goodbye to uncomfortable dry skin and sinuses, making you more susceptible to viruses and other contagions.
Whisper-quiet. Traditional wide ducting isn’t insulated and acts like mini echo chambers throughout the home – especially in older homes. Unico System customers often forget their system is running because it’s whisper quiet. Engineered with special sound-absorbing air supply tubing means there’s no creaking or vibrating when the system turns on.
Air filtration. Allergens in older homes are prolific. The Unico System has an air filter rated MERV 13, which filters out particles as small as 3 microns, including pollen, dust, and other allergens. Why is MERV 13 important? That’s the standard hospitals use when rating their air systems. Because Unico is a compact system with small air registers, it traps more dust and allergens than traditional and mini-split systems.
Completely customizable. Unico’s SMART Control Board delivers consistent temperature in every room, even rooms that always seem warmer or cooler than the rest of the house. The electronically commutated (E.C.) motor controls the fan speed and can be adjusted to provide a consistent flow of comfortable air while ensuring whisper-quiet operation. This is an ideal feature for older homes which have inconsistent temperatures throughout the house.
