Regular maintenance keeps your air conditioner running efficiently and reduces expenditures. Continue reading for additional advice on maintaining your air conditioner. Air conditioners require some maintenance to function properly. Fortunately, AC repair involves a lot of do-it-yourself projects.
1. Inspect Unit Annually
Your local dealer or the one who set up your central air conditioning should put you on a regular maintenance program that includes more than just changing the filters.
Schedule this checkup for before the cold season begins or perform it right away. Include the following chores in your checkup:
- Monitoring pressures and refrigerant
- Checking the operational temperatures
- Filter maintenance or replacement
- Examining safeguards and controls
- Maintaining and inspecting fans and blowers
- Changing and adjusting fan belts
- Examining and cleaning coils
2. Let Adequate Air In
Too many internal doors closed will throw off the balance of the central air conditioning system, reducing the amount of airflow throughout the entire house. Instead, leave the doors slightly ajar if you prefer some privacy.
3. Clean or Replace Filter
Installing new filters each month in the cold season will increase the efficiency of your central and window air conditioners. If your filters are washable, you may also clean them. For household air conditioning systems, look for the filter’s minimum efficiency reporting value or MERV, which goes from 1 to 12. The higher the number, the better filtration it offers.
4. Keep the Air Cool by Insulating
To make the air inside ducts cold, they should be enclosed in humid attics or crawl spaces. Use foil tape to seal the battery and solid insulation. Wraps provide some insulation for confined places.
5. Fix Leakage
Window air conditioning units are notoriously difficult to properly seal, and ducts can lose up to 30% of their airflow through leaks. Use the time-tested smoke method to detect leaks.
Hold an incense stick at the duct lines for central air conditioning; ignite an incense stick and place it right where the window frame and unit meet for window units. If the smoke spreads, there is a leak. For smaller gaps in ducting, use foil tape; for larger ones, duct mastic; for window air conditioners, place foam between the unit and the window’s frame, taping as necessary.
6. Maintain Your Condenser or Compressor
The air compressor and condenser of a central air conditioning system are often placed at your home’s foundation, outside the building. Get rid of any neighboring bushes, grass that is too tall, leaves, and dangling branches because it functions best when there is around 24 inches of clean space in all directions.
7. Keep Your AC Unit Cool
If your windows have treatments like blinds or shades, keep them drawn during the day to prolong the life of your air conditioning system. You may also install awnings to protect south-facing windows from harsh sunlight. To more efficiently move cooled air, think about using the AC alongside floor or ceiling fans.
8. Install Timer
While you are at work, there’s no need to crank up the air conditioning. Install a thermostat that is programmable for central units so that you can set warmer temperatures when you are away and colder temperatures when you are home.
Thermostats and timers are already integrated into newer window units, or you can purchase one for $10 to $20 at any home store; just make sure the voltage is right for your device. Do not turn off the system unless you are going on vacation.
9. Get an Efficiency Upgrade
Federal regulations mandate that AC units be much more energy-efficient than they were even ten years ago. The statistic is known as the seasonal energy-efficiency ratio, or SEER, for central air conditioning; it is known as the energy-efficiency ratio, or EER, for window units. Although a SEER of 13 and an EER of 8 are required by the requirements, equipment with greater figures will be less expensive to operate.
