2 Signs that your AC Unit may be low on Freon

Refrigerant is not consumed in the air conditioning process. If you suspect a leak, you should see if your technician can find it and repair it.

Refrigerant stays constant in your unit. It is not consumed during the air conditioning process. It only needs to be replaced when there is a leak in the system. Getting the ‘freon’ or refrigerant recharged in your system should not be a part of regular maintenance if your system is working properly. Two signs that your unit may be low on freon:

  1. You are not getting the 20 degrees difference between the supply and return air. See our tip on checking to see  if your system is functioning properly for more information on this.
  2. You see oil around the unit.

6 Steps to Clean your AC Condenser

Clean your condenser annually. For most condensers this is simply a matter of hosing off the condenser unit. The units are a network of metal tubing and fins designed to dissipate the heat that your AC has removed from your house. You can usually find your condenser outside in the backyard. These units are designed to be out in the weather, but dirt collects in them. This cuts down on AC efficiency.

Clean your condenser annually to ensure better AC performance

To clean your condenser, follow the steps below:

  1. You will need a garden hose, a spray nozzle and a water source.
  2. Turn off electricity to the unit. The disconnect is sight of the unit.
  3. Do not disassemble the unit for cleaning.
  4. Spray the unit vigorously across all the fins but be careful not to spray directly on the motor.
  5. Look for large chunks of spider webs or leaves getting stuck and not coming out. Sometimes spraying water from another angle will break those up so they will wash away.
  6. The unit will dry itself.

This type of cleaning can be done by a trained professional, or you can have your installer or service technician show you how you can do this yourself. Always keep the area around the condenser free of debris so it will have proper airflow.

4 Steps to check if your AC unit is functioning properly

Here are some simple steps to see if your air conditioning is working properly. You will need a thermometer.

  1. The AC unit should be operating for at least 5 minutes prior to testing.
  2. Measure the temperature at the return air vent. This is the place inside your house where the air returns to your AC unit. It is the large vent that sucks IN air, and is usually under the furnace or in a hallway.
  3. Next measure the temperature of the supply vent closest to your AC unit. This is the vent that is blowing air OUT.
  4. A temperature difference between the return air and the supply air of approximately 20 degrees indicates proper functioning for most AC units.

If you find that your system is not operating in this range, schedule a time for us to have a look at your system. (562) 944-2118.
