The answer to 'types of installation' is that there are several common types of HVAC system installations for homeowners to consider. The most common are central air conditioning, furnace and air conditioner, heat pump, and ductless mini-split systems. Central air conditioning systems have an outdoor compressor unit and indoor air handler that circulate cooled air through ductwork. Furnace and air conditioner systems use a furnace for heating and a separate air conditioner for cooling. Heat pump systems provide both heating and cooling from a single outdoor unit. Ductless mini-split systems have an outdoor compressor and one or more indoor air handling units, without the need for ductwork.
The type of installation that is best for a home depends on factors like the home's size, existing ductwork, energy efficiency needs, and budget. Homeowners should consult with a professional HVAC contractor to determine the most suitable system for their home and needs.
