How To Reduce Cooling Costs With an Aging AC Unit

Old Air Conditioner

Your AC uses more energy than any other appliance in your home. But, if you live in Florida, you know it’s a necessary expense. Unfortunately, your HVAC system becomes increasing obsolete with every year, while losing efficiency. So, with summer temperatures soaring, how do you reduce cooling costs with an aging AC unit.

How Can I Make My Old Air Conditioner More Efficient?

You may have read that you need to replace your air conditioning unit every 10 to 15 years. That number can intimidate a lot of homeowners, especially considering the cost of a new unit.

Many homeowners wait until their old unit gives out before replacing it because of the expense. If not ready to update, you can still reduce cooling costs with an aging AC unit.

Here are a few tips to keep costs low.

  1. Replace air filters regularly to reduce the load on the air handler.
  2. Check your ductwork for leaks.
  3. Install a programmable thermostat so your unit isn’t running when you’re not home.
  4. Clean the evaporator coils on your indoor unit and the condenser coils on the outdoor unit annually.
  5. Ensure the condensate drain on your outdoor unit is running freely to improve humidity removal.
  6. Limit the use of your stove and oven — use the microwave instead.
  7. Take shorter showers and use the vent fan to reduce humidity in your home.
  8. The cold-water laundry cycle produces less humidity than warm water.
  9. Run your clothes dryer in the evening when the heat load is lower, and make sure your dryer vents are free of lint to prevent hot air from backing into your home.
  10. Turn off heat-producing electronics when not in use.
  11. Switch from incandescent lightbulbs to non-heat-producing LED bulbs.
  12. Insulate your ductwork if it hasn’t already been done.
  13. Shut the blinds and curtain during the day and add blackout curtains to south-facing windows.
  14. Install ceiling fans to provide comfort at a higher thermostat setting.
  15. Seal up any gaps around doors and windows with the appropriate caulk or excluder strips.
  16. Plant fast-growing shade trees and shrubs around your home.
  17. Get that yearly tune-up to help keep an old AC system in its best condition.

The good news is that these 17 tactics will help you reduce energy costs no matter the age of your air conditioning system.
