When you need air conditioning repair or replacement, you can usually just replace your current unit with the same heating, ventilation, and air conditioning (HVAC) system. Depending on the climate in your region, you can decide which type of HVAC installation you need. Some homes in areas where the winters are very cold will need a high AFUE rated furnace to heat their home and a large central air conditioner (up to 5 tons) to cool their home. In other areas with more mild climates, you may only need a heat pump to regulate your home’s temperatures, or you could use a ductless AC system instead of installing a full HVAC system.
When installing a home HVAC system, most homeowners choose to to install a furnace and central AC unit that uses ductwork to circulate heat and cooled air. However, you can also use a heat pump to utilize heat outside of your home and within to control temperatures. There are also ductless air conditioners that can heat and cool a home as well.
