A <strong>packaged unit<\/strong> combines all components into a single outdoor cabinet, often used when indoor space is limited. A <strong>ductless mini-split<\/strong> pairs an outdoor condenser with wall-mounted indoor heads and requires no ductwork. Within split and packaged systems, the heating and cooling method can vary \u2014 heat pump, straight cool A\/C with electric heat, or gas furnace with A\/C.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"this.classList.toggle('open');this.nextElementSibling.classList.toggle('open')\">Is a heat pump different from an air conditioner?<\/button>\r\n <div class=\"faq-a\">A heat pump is a type of split system (or packaged system) that provides both heating and cooling from one unit by reversing the refrigerant flow. A straight cool A\/C only cools and relies on a separate heat source \u2014 electric heat strips or a gas furnace. Both are valid options for Lowcountry homes depending on your setup and comfort goals.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"this.classList.toggle('open');this.nextElementSibling.classList.toggle('open')\">Do you provide AC repair in Charleston, SC?<\/button>\r\n <div class=\"faq-a\">Yes. Air conditioning repair is one of our core services throughout Charleston and nearby Lowcountry communities. If your system isn't cooling, has weak airflow or won't turn on, call <a href=\"tel:+18438107886\">843-810-7886<\/a> and we'll help you figure out the next step.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"this.classList.toggle('open');this.nextElementSibling.classList.toggle('open')\">Do you serve Summerville, SC?<\/button>\r\n <div class=\"faq-a\">Yes. Summerville is a primary part of our service area along with Charleston. We also serve surrounding Lowcountry communities \u2014 if you're nearby, call and we'll let you know whether we can reach you.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"this.classList.toggle('open');this.nextElementSibling.classList.toggle('open')\">When should I schedule HVAC maintenance?<\/button>\r\n <div class=\"faq-a\">The best time is before the demanding seasons: cooling equipment in the spring ahead of Charleston's hot, humid summer, and heating equipment in the fall before winter cold snaps. Seasonal tune-ups help your system stay ready when you need it most.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"this.classList.toggle('open');this.nextElementSibling.classList.toggle('open')\">When should I replace my HVAC system?<\/button>\r\n <div class=\"faq-a\">Replacement often makes sense when repairs become frequent, efficiency declines, the system struggles with humidity and temperature control, or the equipment is approaching the end of its typical service life. We evaluate your system and give an honest repair-or-replace recommendation.<\/div>\r\n <\/div>\r\n <div class=\"faq-item\">\r\n <button class=\"faq-q\" onclick=\"this.classList.toggle('open');this.nextElementSibling.classList.toggle('open')\">How can indoor humidity affect home comfort?<\/button>\r\n <div class=\"faq-a\">In the Lowcountry, excess humidity can make a home feel warm and stuffy even when the temperature is set correctly, while air that's too dry can feel harsh. Balanced humidity, together with proper filtration and airflow, is a key part of whole-home comfort.<\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n<\/section>\r\n\r\n<!-- \u2550\u2550\u2550 CTA BANNER \u2550\u2550\u2550 -->\r\n<div class=\"cta-banner\">\r\n <h2>Rule Your Comfort<\/h2>\r\n <p>Need heating, cooling or indoor air quality service in Charleston or Summerville?
