The final price will be determined by your location, the brand you choose and the amount of BTU you want. Once you've determined who you want to hire to replace your HVAC system, determine how you'll pay for the replacement. Spending a little more on the cost of a mini split air conditioner allows homeowners to cool individual areas. The central air replacement cost includes new equipment, just the right size for your home, a new air conditioning cabinet with an ECM fan motor and an air conditioning evaporator coil.
Since the size of your home determines how many BTUs your air conditioner should have, the size of the unit you need will vary depending on the exact square footage of your home. A heating, ventilation and air conditioning (HVAC) system controls heat, humidity, and airflow inside a building.
