8 Things You Can Expect During an Air Conditioning Tune-Up

At RCM, our Precision Tune-Up and Professional Cleaning includes a thorough inspection and cleaning of your air conditioner, which can prevent or catch problems early and avoid a diagnostic call later in the summer. Here are eight of the main steps that you can expect during your annual maintenance appointment with RCM Heating and Cooling:
  1. Check the thermostat and batteries. Even if the thermostat’s batteries are low, the display could appear to be working normally. It will still show the correct temperature, but it simply won’t turn the system on when it’s supposed to. Only when the batteries are extremely low will the display start to dim. It’s best to change the batteries in your thermostat at least once a year.

  2. Inspect the air filter. Clogged air filters restrict air flow, which force the equipment to work harder to move the air through the filter. This is one of the most common causes of reduced energy efficiency in your HVAC system. If the air filter becomes extremely clogged, it can cause the condenser to freeze up and cause serious damage to both the air conditioner and the furnace.

  3. Check air flow in the ducts. A clear duct system allows the cool air to distribute evenly throughout your home, so that all of your rooms are the same temperature. If air flow becomes too obstructed, this may also cause your air conditioner to freeze.

  4. Turn off the humidifier. In this climate, humidity increases during the summer months, which means your humidifier will not be necessary. In fact, it’s your air conditioner’s job to dehumidify the air before sending it into your house.

  5. Clean the condenser and the condenser electrical compartment. Fans can become clogged over time, which prevents the air conditioner from effectively cooling the refrigerant. This can lead to overheating and an overuse of electricity. A half-clogged fan can use up to two times more electricity than a clean fan.

  6. Inspect the contactor and capacitor. Both the contactor and the capacitor help to transfer power to your air conditioner, allowing it to start smoothly. If either of these parts are faulty or worn out, your air conditioner may no longer start when it’s needed.

  7. Measure refrigerant level using subcooling or superheat method. At least half of the air conditioners we encounter are not running at full capacity because they are overcharged by another company that only tested the temperature. Instead of the measuring the temperature alone, we base the amount of refrigerant needed on the load calculation for the equipment, allowing us to add or remove the correct amount.

  8. Measure the current draw of the compressor and fan motor. As your air conditioner and its fan motor wear out over time, they begin to draw more electricity. By measuring the current draw, we can isolate problems within the unit or determine when it’s time to replace either the motor or the entire unit.
