Here are tips to help decide when to possibly replace your air conditioner.
• The average lifespan of an A/C system can range between 10 to 12 years. If the unit is more than 10 years old, consider replacing it with a more efficient system. Newly manufactured air conditioners must have a SEER rating of at least 13. If the current HVAC system has a SEER rating is below 13, energy costs can be cut drastically by replacing it with a new, more efficient unit.
• If the system is having multiple breakdowns and subsequent repairs replacing the unit might be a more affordable option. It is sensible to compare the price of the repairs against the price of a new unit. New units typically come with packaged with anywhere from a 5-10 year parts warranty which can help save the homeowner in the long run.
• R22 refrigerant is being phased out by the government due to its environmental impact. As a result, the costs of refrigerants are rising significantly. If the HVAC unit is using R22 refrigerant, it will need to be replaced eventually in order to switch over to the new type of refrigerant (410A). If you’re having major problems with your air conditioner, especially if they involve the need for more refrigerant, it’s probably a good time to replace your unit.
• Having a hard time maintaining the home at a cool temperature may be a sign of an aging air conditioner or even an incorrectly sized system. Regardless of the cause if the unit is unable to keep the home cool at the desired temperature, it may be time to replace the system.
• Consider replacing the furnace in unison with the A/C unit. Connecting an older furnace to an energy-efficient A/C may prevent it from performing at its rated efficiency.
• The installation and proper sizing of a new A/C system is the key element in deciding efficiency. Too large of a unit will not remove humidity from the home however a unit that’s too small will not be able to provide a comfortable temperature on extremely hot days.
