Protect Your Air Conditioner At Home For Summer
Warm weather is coming, and the last thing you want to discover as you prepare your home for summer is that your cooling system is on the fritz. Whether you enjoy central air conditioning (AC) or use one or more window units, a bit of maintenance goes a long way — and can help extend the life of your home cooling system.
Prepping Your Home Cooling System for Summer
Here’s what you need to do:
1. Change Air Filters: Dust and pollen can clog the filter, causing the machine to work inefficiently, blow warm air and raise your electricity bill. Clean or change your filters once every three months if you run your AC in your home for summer only or once a month if you run your AC throughout the year.
2. Clean the AC Condenser Coils: Remove the protective grilles from your condenser to reach the coils. A refrigerator coil brush or soft brush on a vacuum will allow you to gently clean the outside coils. For stuck-on debris, spray on a coil cleaner, which can be found at stores like Home Depot or Walmart, a local hardware store or online for less than $10. Spray the cleaner from the inside, avoiding spraying the fan or electrical components.
During the off season, you can protect your unit from debris with a condenser cover or tarp, which can be found online or at home improvement stores for $20 to $100. Not all homeowners recommend covering the entire unit and instead will cover only the top of the condenser. A piece of plywood and a few bricks can hold a cover in place.
3. Check AC Units for Debris: Remove any leaves or weeds around the base of the condenser.
4. Clear the Drain Line. The drain or condensate line is located near the indoor cooling coil. You can clear the drain by flushing one cup of bleach, followed by a gallon of water, through the drain. Or, you can use a shop vacuum to suction out any clogs.
5. Lubricate Moving Parts: Put a few drops of lightweight oil or spray WD-40 on any moving parts, such as the fan blades, to prevent friction.
6. Check the Coolant Lines: Ensure that the refrigerant tubes or pipes that run from the evaporator to the condenser are covered well with insulation foam. Replace any foam insulation on areas that are missing or worn.
7. Turn Off Water to the Furnace Humidifier: If you have a central humidifier, shut off the humidifier before using your air conditioner. Forgetting to switch off the humidifier will prevent your unit from properly cooling your home.
8. Power on Your AC: After your unit has dried and you’ve put it back together after the maintenance check, it is time to ensure your cooler runs properly. Begin by turning off your home thermostat. Then switch on the power at both the disconnect box and at the main panel. Finally, set the thermostat setting on the unit to cool.
Keeping Your AC Window Unit Running Smoothly
An AC window unit does not need as much yearly maintenance as an HVAC system, but 20 minutes of cleaning at the beginning of the summer season will help keep your cooler running efficiently. First, unplug your unit and then follow these quick steps to prepare your window unit:
1. Clean the Filter: The filter is located right behind the front grill that blows air into your room. Depending on your unit, the grill will slide out or will need a quick unscrewing to release it. If it’s a paper filter, you’ll need to replace it. You can find filter replacements at stores like Target, Walmart or local hardware stores. Be sure to bring your old filter with you so that you purchase the right size. If your window unit has a mesh filter, clean it with warm, soapy water and let it dry thoroughly. If you notice any mold on the filter or grill, wash it in a solution of bleach and water.
2. Vacuum the Coils: The evaporator coil and condenser coil need to be gently cleaned with a soft vacuum brush. The evaporator coil is behind the filter and the condenser coil is behind the compressor. These coils can bend easily, so use a delicate hand when vacuuming them. If you notice that any of the coils are bent, use a fin comb (which can be purchased online or at your local hardware store) to carefully straighten the coils.
3. Check the Window Seal: Finally, wipe down the outside of the unit and check the window seal for cracks or wear. If there is a gap, add adhesive-backed foam weather stripping inside the gap to ensure a proper seal.
4. Test Your Unit: Once everything is cleaned, dried and reassembled, connect the unit back to the power source and test it out. Depending on how often you use your window AC in your home for summer, you should clean the unit once or twice more before autumn.
Insurance Endorsement for Year-Round Protection
Fixing or replacing your air conditioner can be costly. Depending on the problem, an AC repair can cost between $168 and $605. Installing a new central air unit can cost over $7,000. You shouldn’t have to suffer financially to beat the heat.
For example, The Hartford’s equipment breakdown coverage helps cover things like your:
Home security system
Dishwasher
Water heaters
Well pumps
Heating and electrical systems
Lawn mower
Stovetop
Swimming pool equipment
Television
Washer and dryer
Adding this endorsement to your homeowner’s policy covers up to $50,000 to repair or replace equipment due to electrical or mechanical breakdown. In most cases, your payout equals the replacement cost of the piece of equipment, less a $500 deductible. The plan can also cover the costs of expediting the repair or replacement, so you don’t have to worry about your family’s health and well-being on top of a broken appliance.
Knowing When It’s Time for a New Unit
Even with proper care, AC units do have an expiration date. According to Energy.gov, a 10-year-old central air unit can cost you 20% to 40% more in energy costs, when compared to a newer, more efficient model.
Preparing your home for summer sometimes isn’t enough. Hiring a professional might be necessary to fix any cooling issues before a problem gets worse. Adding equipment coverage attached to your homeowners, condo or renters insurance policy can give you peace of mind that you won’t have to suffer long with a broken air conditioner, washing machine or other important appliance you use often.
