Your air conditioning system is aging and it's time to think about replacing it. But how do you know when it's the right time to upgrade? According to Hughes, an expert in the field, it really depends on how well the system has been installed and maintained. The Department of Energy suggests replacing your HVAC system after 10 years for maximum efficiency. Some newer models can last up to 15 years, so make sure to check when yours was installed and ask a professional how long it should last. Generally, central air units last 12 to 17 years with average use and good maintenance.
The size of the unit does not influence the lifespan of the air conditioner, unless it is not suitable size for your home. For instance, if you have a small 1.5 ton air conditioner trying to cool a house that actually needs a 5 ton air conditioner, the unit will break down much faster from overuse than a suitably sized (but more expensive) unit. The only way to be certain if your heating, ventilation and air conditioning system is underperforming or if it is overworked is through a professional energy audit or an inspection by an HVAC technician. Many utility companies offer discounts on heating, ventilation and air conditioning systems when you're ready to upgrade your air conditioning system to a model that saves energy. Apart from safety considerations, HVAC professionals can purchase units directly from manufacturers and install their unit quickly following appropriate protocols. If your home isn't properly insulated or professionally sealed, the lifespan of your air conditioning system is automatically shortened.
If your HVAC system is more than 10 years old, it's time to plan for major repairs or replacements. In addition to making costly repairs in the future for faulty or poorly installed equipment, your HVAC system can filter carbon monoxide or other toxins that expire in your home. For this reason, HVAC units must comply with building codes and professionals must meet strict installation guidelines. Air conditioning technology has advanced significantly, and your home's energy efficiency is affected simply by keeping the older air conditioning technology.
