They say knowledge is power, and that’s undoubtedly accurate when talking about your air conditioner. While complex repairs are best left to experts, it’s helpful to have a basic understanding of your air conditioner and how to solve everyday AC issues.
Understanding how your AC works and the frequent problems it faces will allow you to deal with easy problems without needing to call an HVAC specialist every time. This not only saves you dollars on minor service calls, but realizing when to reach out to a professional can help prevent small issues from escalating into complex repairs.
Your Air conditioner is an essential component of your home comfort. Because of that, you should always err on the side of caution and call a NATE-certified professional for air conditioning repair in The Bay Area if you're uncertain about any aspect of your AC's operation or maintenance.
Here are some frequent questions people ask our experts about their air conditioners:
1. How Do I Clean an Air Conditioner?
Cleaning an air conditioning system is an effective way to make sure it operates efficiently, and potentially could extend the life of your unit.
The most effective action you can take on your own is to replace 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 really should in order to move air through the filter. A clean filter removes the airborne debris while still permitting air to flow efficiently through the system.
Replacement filters are available at most leading home improvement stores, hardware stores or can be ordered from your local HVAC specialist. A good way to make sure you get the right filter is to look at your old one before you go shopping, noting the size of the filter. If you’re not familiar with filters, it’s also helpful to note the filtration level of the current filter if you are trying to buy something similar.
For thorough service of your air conditioner, contact the skilled professionals like the crew at Contra Costa Heating & AC to do routine maintenance on your unit. They’ll look over your system, clean or lubricate parts that need it and look for worn-out parts and potential trouble.
2. How Do I Clean Air Conditioner Coils?
In addition to making sure your indoor air conditioning unit is functioning efficiently, it’s important to tend to your outdoor unit. Cleaning the coils on the exterior unit of your AC is a quick 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 to the outdoors. This brings down the temperature of the refrigerant, which then goes back in your home so it can absorb more heat from the air in your home's interior. Cleansing the fins and the coils can help them release heat more easily.
To clean your air conditioner’s fins and coil:
1) First, shut off power to the outdoor unit. It’s best to flip off the the on/off switch, rather than turning the thermostat off.
2) Take off the top of the outdoor AC so you can access the interior of the unit. Then, being cautious not to pull hard on any cords or attachments, safely move 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 in the form of foaming solutions that are sprayed on with your garden hose.
4) Follow directions on the product to apply. For most cleaners, it's recommended that you spray the product on, let the cleaner soak in for a small period of time to dissolve the grime and then softly spray it off with a garden hose. Take care not to spray really hard, because that could harm the coils or fins!
5) Secure the top back on the unit and then wait for the components to dry before turning the unit back on.
3. How Long Do Air Conditioners Last?
The life span of an air conditioner depends on the type of unit, its quality, how often it's maintained and how often it's used. That said, pros say you should start getting ready for air conditioner replacement after about 12-15 years.
One of the best ways to make the most of your air conditioner is through regularly scheduled conditioner maintenance. Tuneups from Contra Costa Heating & AC features cleaning and inspecting the machinery, as well as putting in a new filter and fixing any worn-out or broken parts.

4. What Size Air Conditioner Do I Need?
Selecting the right size of air conditioner for your home is critical for achieving comfort and efficiency. Here are some factors to consider when deciding what size air conditioner you need for your home:
- Square footage: The amount of space you want to cool is one of the biggest factors. More expansive spaces necessitate more cooling power.
- Home insulation: Well-insulated homes retain cool air better, which can reduce your cooling needs.
- Climate: If you are living in a hotter climate, you'll need a more powerful air conditioner compared to a person living in a cooler place.
- Number of windows: Windows often let in heat, particularly when they're south-facing or not well-insulated.
- Number of occupants: More people in the house means greater body heat, which may impact your cooling needs.
- Existing HVAC system: The size and capability of your current system can provide a place to start for deciding what you need.
Because the size of your air conditioner is so important to your home’s comfort, you will probably want a professional opinion. At Contra Costa Heating & AC, we take the time to thoroughly understand your family’s lifestyle, comfort needs and the many other considerations such as your home’s layout and size.

5. How Much Does an Air Conditioner Cost?
While prices fluctuate depending on the size of the unit and your home’s unique specifications, a new air conditioner generally costs between $5,000 and $12,500 to purchase and install. The good news is that new air conditioners are crafted to be exceptionally efficient, so they do more with less power when compared to older units.
The cost of an air conditioner is affected by several factors during the manufacturing process, such as the cost and availability of raw materials, manufacturing and labor costs as well as federal regulations that necessitate changes to the design.
Know these are average costs and prices can vary. It's always smart to get at least a few quotes from trusted HVAC companies before making a decision.

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 AC's inability to efficiently transfer heat. If your air conditioner is experiencing issues causing it to freeze up, it is most likely time for air conditioning repair.
Here are some frequent triggers for AC freezing up:
- Insufficient airflow: If the air isn't flowing correctly through your AC system, it can't sufficiently absorb heat. This could be due to a plugged 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 may get too cold and freeze up. This is usually a consequence of leaking in the refrigerant lines.
- Very Chilly outdoor temperatures: Operating an air conditioner when it's very cold outside can cause the system to freeze. The majority of units aren't designed to operate in temperatures of less than 60 degrees Fahrenheit (15 degrees Celsius).
- Mechanical failures: Broken thermostats, damaged blower motors and trouble with the relay or control board can all play a role in an AC unit freezing up.
