An 18000 btu mini split heat pump ac may be the solution you are looking for to make the square footage in your home / recent addition / workshop / office / entertainment room / in-law suite more comfortable. An 18000 btu ductless system can cover approximately 600 to 800 sqft within certain parameters (8ft ceiling, closed room, decent insulation, efficient windows, low foot traffic, etc.). With a change to any of the previously mentioned parameters you would simply adjust the coverage to match, but within them you are good to go with coverage for a 600-800 sqft area easily and affordably made comfortable. Speak with you HVAC installer to get a more specific measurement on what you need.
While its size allows for the coverage of a large area, the 18000 btu heat pump ac system is also the beginning of the sizes where you have the option to start looking into dual zone solutions. With multiple zones you would be able to utilize two 9000 btu indoor units, allowing you to cover separate areas while still operating on a single exterior unit, maximizing you electrical efficiency and keeping your monthly bill down. As such the 18000 btu heat pump ac system is a size that boasts the versatility for single or dual zone solutions to best fit your heat pump ac needs.
Finding the BEST heat pump ac system requires you to look closely at what you actually need vs what you think will work. Aside from your square footage needs, and how many zones you are looking to cover, your actual location is one of the most important factors. Are you in a temperate climate, or more sub-tropical? Do you have torrential downpours, calm cool breezes, hail and sleet or more of a sun-bleached desert vibe? Certain systems can only function down to particular outdoor or ambient temperatures, so make sure to keep that in mind when making your choice. You may not need to spend the extra money on a subzero system if you are in the swamps and bayous of the south. But dealing with a few feet of snow for half the year up north calls for low ambient temperature solution.
