Ductless Heating & Cooling
One of the many benefits of mini–split systems is that they can also be used to heat your home. While the primary application is cooling (as most homes without ductwork already have boilers), adding a heat pump allows for winter time heating as well. This lets you reduce the space used by your heating system as well and minimize maintenance needs many times over.
If you are interested in heating with mini–splits, make sure you discuss your requirements with a contractor. While cooling is often a room by room operation, heating has a number of other factors to consider.
Ductless Split Maintenance
While you won’t have any ductwork to worry about, you will still have an outdoor condenser that needs to be maintained to keep your heating and cooling system operational. To avoid any problems make sure no debris builds up around the system.
Grass, leaves, debris or shrubs can all block the system, reducing efficiency or causing other problems. There are also screens and filters on your system that need to be properly maintained – cleaned of excess debris and washed on a schedule recommended by the manufacturer.
Choosing a Mini Split System
Ductless mini split systems are popular for a number of reasons, but energy efficiency is one of their primary selling points. These systems can save you hundreds of dollars every year if installed and used properly. However, the actual benefits will depend on which system you buy based on your unique needs, how it is installed and your current energy costs.
When looking for a system, check air conditioners for a SEER rating, the number used to rate their efficiency. If you are buying one that offers heating as well, look for HPSF ratings – a number that designates heat pump efficiency.
Ductless Split System Sizing
A major problem seen in homes with existing ductless systems in place is improper sizing. This happens frequently when insulation is not properly measured. For this reason, make sure you hire someone with a lot of experience sizing ductless mini split systems. These systems require a different approach than traditional forced air systems.
