4 Steps to check if your AC unit is functioning properly

A difference of 20 degrees (F) between your supply and return vents shows proper function

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.

Tip #3: How to Decide if You Need a More Efficient AC Unit

Timing an efficiency upgrade with a major repair helps recoup the cost of the upgrade more quickly.

People often ask me if they should get a new unit that is energy efficient. If your goal is to save money, it is best to do the math and see if this is cost effective.

  1. It depends on how much and how often you use your unit.
  2. Compare your winter bill usage to your summer bill usage. Look at the kilowatt usage, not just the dollar amount because summer charges are usually higher per kilowatt. Considering the difference between summer and winter usage, a more efficient unit will only save a percentage of this amount.
  3. Do the math and decide if the amount of money you will save is worth the cost of a new unit.
  4. Timing an efficiency upgrade with a major repair helps recoup the cost of the upgrade more quickly.

We’ll talk about some situations where it makes more sense to upgrade to a more efficient unit in a future tip.

Tip # 2 Check the Power

Circuit Breakers

I know you will be rolling your eyes on this one. But you would be surprised at how many times we get called for a breakdown when the only problem is a tripped breaker. This simply means that the circuit no longer has power and needs to be reset by turning off the breaker and turning it back on. It is usually a double breaker marked AC.

Now, of course, if you have repeated experiences with the breaker tripping, you should probably have the system looked at by a professional.

If you suspect that your unit requires a repair, don’t take a chance, give us a call at (562) 944-2118.

Tip #1 : 3 Benefits of Changing Your AC Filter Regularly

Heating and Air Conditioning Filter

Change your filter every 2 to 3 months. A clean filter allows for easy airflow through your system. Many bigger problems can be avoided if your filter is kept clean.

Keep in mind that the filter should cover the entire opening and should be held in place by a clip or other fastener.

We’re always happy to show a homeowner how to change their own filter during a service call.

We could write chapters about why airflow is important to your unit, but if you keep your filter clean you may never need to know the scientific principles of your AC unit.

If your AC needs repair or service, please call us at 562-944-2118 to set up an appointment.
