An <strong>outdoor compressor<\/strong> connects to one or more <strong>indoor air handlers<\/strong> through a small wall opening. <strong>Refrigerant lines<\/strong>, a <strong>power cable<\/strong>, and a <strong>condensate drain<\/strong> run through that opening.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Component<\/th><th>Where It Sits<\/th><th>What It Does<\/th><\/tr><tr><td><strong>Outdoor unit (compressor)<\/strong><\/td><td>Exterior pad or wall bracket<\/td><td>Moves heat in or out of the home<\/td><\/tr><tr><td><strong>Indoor head (air handler)<\/strong><\/td><td>High on an interior wall<\/td><td>Blows conditioned air into the room<\/td><\/tr><tr><td><strong>Line set<\/strong><\/td><td>Through a 3-inch wall hole<\/td><td>Carries refrigerant between units<\/td><\/tr><tr><td><strong>Condensate line<\/strong><\/td><td>Alongside the line set<\/td><td>Drains moisture away from the indoor unit<\/td><\/tr><tr><td><strong>Remote or wall controller<\/strong><\/td><td>In each room<\/td><td>Sets temperature for that zone only<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Each indoor head runs <strong>independently<\/strong>.

Many homes are <strong>subdivision colonials, two-stories, and ranches<\/strong> from that era. Plenty of them have <strong>limited ductwork<\/strong>, or rooms that were added after the original <strong>HVAC system<\/strong> was sized.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here&#8217;s what we see most often in homes like these:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Bonus rooms over garages<\/strong> that bake in July and freeze in February<\/li>\n\n\n\n<li><strong>Sunrooms and four-season rooms<\/strong> with big glass walls and no duct runs<\/li>\n\n\n\n<li><strong>Finished basements<\/strong> that feel damp in summer and chilly in fall<\/li>\n\n\n\n<li><strong>Additions<\/strong> built without extending the main <strong>trunk line<\/strong><\/li>\n\n\n\n<li><strong>Upper floors<\/strong> that run 5 to 10 degrees warmer than the main level<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Our plumbers frequently see the same pattern in older New Jersey homes. The <strong>central system<\/strong> works fine for the main floor but can&#8217;t push air to the far rooms. Extending <strong>ductwork<\/strong> means opening <strong>ceilings and walls<\/strong>, which gets expensive fast. <em>A mini split skips that demolition entirely.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Single-Zone vs. Multi-Zone: Choose the Right Design<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>single-zone system<\/strong> pairs one <strong>outdoor unit<\/strong> with one <strong>indoor head<\/strong>. A <strong>multi-zone system<\/strong> connects one outdoor unit to <strong>two to five indoor heads<\/strong>. The right choice depends on how many rooms truly need <strong>independent comfort<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th>Factor<\/th><th>Single-Zone<\/th><th>Multi-Zone<\/th><\/tr><tr><td><strong>Best for<\/strong><\/td><td>One problem room<\/td><td>Several rooms with different needs<\/td><\/tr><tr><td><strong>Outdoor units<\/strong><\/td><td>1 per room<\/td><td>1 for up to 5 rooms<\/td><\/tr><tr><td><strong>Install time<\/strong><\/td><td>About 4 to 6 hours<\/td><td>Usually 1 full day<\/td><\/tr><tr><td><strong>Design complexity<\/strong><\/td><td>Simple<\/td><td>Needs careful <strong>load matching<\/strong><\/td><\/tr><tr><td><strong>Efficiency<\/strong><\/td><td>Highest per room<\/td><td>Slightly lower if heads run at low loads<\/td><\/tr><tr><td><strong>Failure risk<\/strong><\/td><td>Affects one room<\/td><td>One compressor failure affects all zones<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Our advice:<\/strong> start with the rooms that cause the most complaints.
