There are three main types of HVAC systems that are used in residential homes. Each type of system differs in parts, sizes, and most importantly cost. Knowing which type of HVAC system is in your home is the first thing to consider when estimating the cost to replace. The three types of HVAC systems are:

  1. Split Systems: The most common type of HVAC system; designed with two main units, one for heating and one for cooling. The cooling system is usually located outside and uses a fan, refrigerant, compressors, and coils to remove hot air from the house. The heating system is usually located in the basement and uses gas or electric and ductwork to produce and circulate heat in the house. A split system often has the most affordable equipment but the highest installation cost due to the required ductwork. The cost to replace only the equipment for a standard 14 SEER split system can range between $7,500 – $10,000.
  2. Mini-Split (Ductless) Systems: A unique type of HVAC system that has individual units in each room. These types of systems are usually visibly mounted on indoor walls and attached to an outdoor compressor. Ductless systems do not require ductwork to operate which can save money on installation costs, but they often cost more for equipment since you’ll need a unit for each room. The cost to replace only the equipment for a standard single zone ductless system can range between $8,000 – $15,000.
  3. Packaged Systems: This uncommon type of HVAC system is designed with all its major parts packaged together into one cabinet. These types of systems are usually installed outdoors and use a blower to circulate air in and out of the home. Packaged systems can run on either a heat pump or gas and electricity. Packaged systems are fully assembled by the manufacturer which saves you money on installation costs, but they often require more frequent maintenance due to all the major components being exposed to the outdoors. The cost to replace only the equipment for a standard 14 SEER packaged system can range between $10,000 – $14,000.
