The answer to 'types of replacement' is that there are several common types of HVAC system replacements that homeowners may need to consider. The most common are full system replacements, partial system replacements, and equipment-only replacements. Full system replacements involve replacing the entire HVAC system, including the furnace, air conditioner, and ductwork. Partial system replacements involve replacing only one component, like the air conditioner or furnace, while keeping the rest of the system. Equipment-only replacements involve just replacing the indoor or outdoor unit without changing the rest of the system.
The best option for a homeowner will depend on the age and condition of their existing HVAC system, their budget, and their home's specific needs. It's important to work with a qualified HVAC technician to evaluate the system and determine the most appropriate replacement option.
