When your heating system reaches the end of its useful life or breaks down beyond economical repair, replacing it with a modern, energy-efficient system is often the smartest long-term investment. At Sunnyside AC, we specialize in heating system replacement services throughout South Florida for heat pumps, furnaces, and ductless mini-split heating systems. Our certified technicians help you upgrade to reliable, efficient heating that will serve your home for 15-20 years. Signs you need heating replacement include the system is 12-15+ years old, requires frequent repairs, repair costs exceed 50% of replacement cost, can't maintain comfortable temperatures, uses outdated R-22 refrigerant (heat pumps), produces excessive noise or unusual odors, causes high energy bills, and fails safety inspections. If your heating system exhibits multiple warning signs, replacement is typically more cost-effective than continued repairs. We replace all types of heating systems including heat pumps (most common in South Florida - provides heating AND cooling), electric furnaces, gas furnaces, ductless mini-split heat pumps, and outdated electric heat strips with modern efficient systems. Modern high-efficiency heat pumps (9+ HSPF) can reduce heating costs by 50-75% compared to older systems while also providing exceptional cooling efficiency for our hot summers. Our heating replacement process includes complete evaluation of your current system, detailed load calculations for proper sizing, expert recommendations based on your climate needs and budget, professional removal and disposal of old equipment, installation of new heating system with all connections, permits and code compliance, thorough testing of both heating and cooling modes (heat pumps), manufacturer warranty registration, and complete operation training. We handle everything so you get reliable, worry-free heat. We offer flexible financing options and help you access manufacturer rebates, utility incentives, and federal tax credits for high-efficiency heating systems. Every replacement is backed by our workmanship warranty and manufacturer equipment warranties. For South Florida homes, we especially recommend heat pump systems that provide year-round comfort—efficient cooling when needed most, plus cost-effective heating during brief cold spells.
