DIY Air Conditioning Maintenance

by | Jan 27, 2025 | Blog | 0 comments

Your air conditioning system works tirelessly to keep your home cool and comfortable, especially during the scorching summer months. Regular maintenance is essential to ensure your system operates efficiently and has a long lifespan. It helps save energy by reducing strain on the system, lowers the risk of unexpected breakdowns, and improves overall air quality in your home. While professional servicing is always recommended, there are several steps you can take as a homeowner to keep your AC in top condition. Follow this detailed guide from Precision Heating & Cooling, Inc. to perform your own air conditioning maintenance.

Tools You’ll Need:

  • Screwdriver set
  • Fin comb
  • Soft-bristle brush
  • Garden hose with a spray nozzle
  • Vacuum cleaner with a brush attachment
  • Microfiber cloth
  • Coil cleaner (available at hardware stores)
  • Replacement air filter
  • Gloves and safety goggles

Step 1: Turn Off the Power

Before starting any maintenance, safety is your top priority. Locate your air conditioning unit’s power switch, typically found near the outdoor condenser unit or at the breaker box, and turn it off. This prevents any risk of electric shock or injury while you’re working on the system.

Step 2: Clean or Replace the Air Filter

Dirty air filters are a common culprit behind reduced system efficiency and poor air quality. When filters are clogged, they restrict airflow, forcing the system to work harder and consume more energy. This added strain can lead to overheating, increased wear on components, and even premature failure of the motor.

    1. Locate the air filter—usually found in the return vent or inside the furnace/air handler.
  2. Remove the filter and inspect it. If it appears clogged with dust and debris, replace it with a new one.
  3. For reusable filters, gently clean them with a vacuum or rinse them under lukewarm water. Allow the filter to dry completely before reinstalling.
  4. Be sure to replace or clean your filter every 1-3 months for optimal performance.

Step 3: Inspect and Clean the Outdoor Unit

The condenser coil in your outdoor unit is crucial for heat exchange. Dirt and debris can obstruct airflow, reducing efficiency.

  1. Use a screwdriver to remove the fan grill or outer casing of the condenser unit.
  2. Clear away any leaves, dirt, or debris around and inside the unit.
  3. Using a garden hose, gently rinse the condenser coils from the inside out. This method helps to push dirt and debris out of the unit rather than forcing it deeper into the coils, ensuring a more thorough cleaning. Avoid high-pressure settings to prevent damaging the fins.
  4. If the coils are heavily soiled, apply coil cleaner, following the manufacturer’s instructions.
  5. Straighten any bent fins using a fin comb.

Step 4: Check the Evaporator Coil

The evaporator coil is located inside your home, typically within the air handler or furnace.

  1. Open the access panel with a screwdriver.
  2. Use a soft-bristle brush to remove any dust buildup on the coil.
  3. Wipe the coil gently with a damp microfiber cloth. If needed, apply coil cleaner.
  4. Ensure the condensate drain is clear. Use a wet/dry vacuum to remove clogs if necessary.

Step 5: Clear the Surrounding Area

A clean and obstruction-free area around your outdoor unit ensures proper airflow.

  1. Trim any vegetation or grass within two feet of the unit.
  2. Remove any outdoor furniture or objects blocking airflow.

Step 6: Test the Thermostat

A malfunctioning thermostat can lead to inconsistent cooling and wasted energy.

  1. Check the thermostat settings and replace the batteries if needed.
  2. Set it to cooling mode and adjust the temperature to ensure the system starts and runs correctly.
  3. Consider upgrading to a programmable or smart thermostat for added efficiency.

Step 7: Inspect Ductwork for Leaks

Leaky ducts can cause significant energy loss.

  1. Visually inspect accessible ductwork for any cracks, gaps, or disconnected sections.
  2. Seal any leaks with aluminum foil tape or mastic sealant. Avoid using duct tape, as it degrades over time and doesn’t provide a reliable seal, which can lead to further energy loss and inefficiency. Avoid using duct tape, as it degrades over time.

Step 8: Reassemble and Power On

Once all maintenance steps are complete:

  1. Reassemble the outdoor unit and secure the panels.
  2. Turn the power back on at the breaker or switch.
  3. Run the system to ensure it operates smoothly and efficiently.
