Ultimately, the decision to repair or replace your 15-year old air conditioner depends on a variety of factors. By weighing the energy efficiency of your unit, the cost of repairs versus replacement, and the availability of tax credits and rebates, you can make an informed decision that will benefit both your wallet and the environment in the long-term.

5. DIY options: tips for maintaining and repairing your older air conditioner yourself


If you have some basic knowledge about air conditioners, you may be able to do some minor repairs by yourself. It is important to note, however, that some repairs require a professional’s expertise. Here are a few tips for maintaining and repairing your older air conditioner yourself:

Clean or Replace Your Air Filters

The air filter is an essential component of your air conditioner. It prevents dirt, dust, and other debris from entering the unit. If the air filter is dirty or clogged, it will cause your air conditioner to work harder and may even lead to health issues. It is recommended to clean or replace your air filters at least once a month or as needed.

Clean the Coils

The evaporator and condenser coils of your air conditioner also collect dirt and dust over time, which hampers their performance. You may use a brush to clean the coils or a commercial coil cleaner, which is available at most hardware stores. Removing any dirt or debris from the coils allows your air conditioner to run more efficiently.

Check the Thermostat

If your air conditioner isn’t cooling your home correctly, the problem may lie with the thermostat. Ensure that the thermostat is set to “cool” and at a lower temperature than the room temperature. If it is a digital thermostat, consider replacing the batteries. If your thermostat is obsolete, it may be worth upgrading to a newer, more energy-efficient unit.

By following these tips, you can ensure that your air conditioner lasts longer and runs more efficiently. Keep in mind that some repairs may require a professional technician’s services. When in doubt, always consult with an experienced HVAC professional.
