Here are some common questions people ask our experts about their air conditioners:

1. How Should I Clean My Air Conditioner?

Cleaning an air conditioning system is an effective way to make sure it runs efficiently, and potentially could extend the life of your unit.

The most important step you can take on your own is to change the air filter in your air conditioner. The filter traps dust, pollen, pet hair and other debris, and removes those particulates from the air circulating throughout your home. If your AC filter becomes plugged, the air conditioner has to work harder than it should in order to move air through the filter. A clean filter catches the airborne debris while still permitting air to flow freely through the system.

Replacement filters are available at most popular home improvement stores, hardware stores or can be bought from your local HVAC professional. A good way to make sure you get the right filter is to look at your old one before you go shopping, jotting down the size of the filter. If you’re not familiar with filters, it’s also a good idea to note the filtration level of the current filter if you are wanting to buy something similar.

For comprehensive service of your air conditioner, contact the seasoned professionals like the crew at Contra Costa Heating & AC to do regular maintenance on your unit. They’ll inspect your system, clean or lubricate parts that need it and look for worn-out parts and potential issues.

2. How Should I Clean the Air Conditioner Coils?

In addition to making certain that your indoor AC unit is working efficiently, it’s necessary to tend to your outdoor unit. Cleaning the coils on the outside unit of your air conditioner is a simple way to boost its efficiency and can extend the life of your entire system.

The coils, which are attached to extensions called fins, are used to release heat from the refrigerant into the outside air. This brings down the temperature of the refrigerant, which then goes back inside your home so it can soak up more heat from the air within your home. Cleansing the fins and the coils will help them release heat more easily.

To clean your air conditioner’s fins and coil:

1) First, turn off power to the outdoor unit. It’s best to disconnect it completely from power, as opposed to turning the thermostat off.

2) Remove the top of the outdoor AC so you can reach the inside of the unit. Then, taking care not to strain any cords or attachments, safely put the top to the side.

3) Spray a cleaning solution on the fins, first at the top and then working your way down. Commercial coil cleaners are available and commonly found in both the canned aerosol spray from as well as products foaming solutions that are sprayed on with your garden hose.

4) Follow directions on the product to apply. For most cleaners, it's suggested that you spray the product on, let the cleaner soak in for a brief period of time to attack the grime and then carefully spray it off with a garden hose. Take care not to spray too hard, because that could ruin the coils or fins!

5) Secure the top back on the unit and then wait for the components to dry before turning it back on.

3. What Is the Average Lifespan of My Air Conditioner?

The life span of an air conditioner depends on the type of unit, its quality, how well it's maintained and how much it's used. Having said that, pros say you should start getting ready for air conditioner replacement after about 12-15 years.

One of the best ways to get maximum value from your system is through AC conditioner maintenance.

Picking out the proper size of air conditioner for your home is crucial for achieving comfort and efficiency. Here are some factors to consider when deciding what size air conditioner is right for your home:

  • Square footage: The total area of the space you have to cool is one of the biggest factors. Bigger spaces require more cooling power.
  • Home insulation: Well-insulated homes retain cool air better, which could decrease your cooling needs.
  • Climate: If you are living in a hotter climate, you'll require a more powerful air conditioner compared to a homeowner living in a cooler place.
  • Number of windows: Windows can let in heat, especially when they're south-facing or not well-insulated.
  • Number of residents: More people in the house means more body heat, which could impact your cooling needs.
  • Existing HVAC system: The size and performance of your current system can provide a jumping off point for deciding what you need.

The good thing is that new air conditioners are crafted to be exceedingly efficient, so they do more with less power when compared to older units.

6. What Causes an Air Conditioner to Freeze Up?

An air conditioner freezing up can be brought on by a number of factors, all of which boil down to the failure of your system to efficiently transfer heat. If your unit is experiencing issues causing it to freeze up, it is more than likely time for air conditioning repair.

Here are some typical triggers for AC freezing up:

  • Poor airflow: If the air isn't flowing correctly through your AC system, it can't properly absorb heat. This could be due to a clogged air filter, something stopping air from flowing through the return air ducts or a failing fan.
  • Low refrigerant levels: If your air conditioner is running low on refrigerant, it could become too cold and freeze up. This is often a consequence of leaking in the refrigerant lines.
  • Cold outdoor temperatures: Operating your air conditioner when it's too cold outside can cause the system to freeze. Many units aren't designed to function in temperatures of less than 60 degrees Fahrenheit (15 degrees Celsius).
  • Mechanical failures: Broken thermostats, damaged blower motors and problems with the relay or control board can all result in an AC unit freezing up.
