When you add on to a home, the extra space needs the same comfort the rest of your home needs. However, the new space was not part of the “load calculations” – the math that was done when your home HVAC system was installed- to cover this additional square footage. While some people will try to add ductwork and just add the addition onto the main heating system, they often find this just leads to more problems with the main system.
Some people will try stop gaps and use space heaters or electric baseboards, but that doesn’t provide you with any air conditioning and they are expensive to run. Sunrooms like this one can get really hot, even on winter days, especially if you have southern exposure, so cooling is a must if you really want to use the space all year long.
When our homeowners contacted us here at Compass Heating and Air, we knew that a single zone Mitsubishi ductless system would not only provide the owners with a cost-effective way to get the comfort they craved but would also save money on energy bills due to its incredibly high efficiency.
Ductless systems, sometimes referred to as mini-splits, are composed of two parts- a wall mounted, indoor unit, connected to an outdoor heat pump condenser unit. The outdoor unit acts as a heat pump and can control up to eight indoor units, with each indoor unit operating independently as its own zone. For this sunroom, only a single zone of ductless is necessary. The indoor unit can act as a heater and as an air conditioner, delivering you the perfect comfort you want, adjusting temperature and humidity as needed and deliver comfortable air throughout a space, avoiding hot and cold spots you could get with space heaters, wood stoves or electric baseboards.
