They say knowledge is power, and that’s certainly true when discussing your air conditioner. While complex repairs are best left to professionals, it’s helpful to have a rudimentary understanding of your air conditioner and how to solve everyday AC issues.

Learning how your AC works and the common problems it faces will allow you to tackle simple problems without needing to call an HVAC specialist every time. This not only saves you money on minor service calls, but understanding when to call a professional can help prevent small issues from escalating into major repairs.

Your Air conditioning unit is an important element 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 Fredericksburg if you're not sure about any aspect of your AC's operation or maintenance.

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

1. What Is the Best Way to Clean an Air Conditioner?

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

The most important action you can take on your own is to swap out the air filter in your air conditioner. The filter captures dust, pollen, pet hair and other debris, and removes those impurities from the air circulating inside your home. If your AC filter becomes choked with debris, the air conditioner has to work harder than it really should in order to move air through the filter. A clean filter catches the airborne debris while still enabling air to flow efficiently through the system.

Replacement filters are sold at most major 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 leave for the store, jotting down the size of the filter. If you’re not familiar with filters, it’s also a smart idea to note the filtration level of the current filter if you are trying to buy something similar.

For detailed service of your air conditioner, contact the seasoned professionals like the crew at Childress Heating & AC to do scheduled maintenance on your unit. They’ll examine your system, clean or lubricate parts that require attention and look for worn-out parts and potential trouble.

2. How Do I Clean Air Conditioner Coils?

In addition to ensuring your indoor air conditioning unit is functioning efficiently, it’s also a good idea to tend to your outdoor unit. Cleaning the coils on the outdoor unit of your cooling system is a simple way to improve 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 cooler air outside. This brings down the temperature of the refrigerant, which then goes back in your home so it can absorb more heat from the air inside your home. Cleansing the fins and the coils will help them release heat more efficiently.

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, instead of turning the thermostat off.

2) Lift off the top of the outdoor AC so you can reach the interior of the unit. Then, being cautious not to pull hard on any cords or attachments, safely put the top to the side.

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

4) Follow directions on the product to apply. For most products, it's recommended that you spray the product on, let the cleaner soak in for a brief period of time to loosen the grime and then gently spray it off with a garden hose. Be careful not to spray too 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 Can Air Conditioners Work?

The life span of an air conditioner depends on the type of unit, its quality, if maintained and how frequently it's used. However, industry experts 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 system is through AC conditioner maintenance. Routine checkups from Childress Heating & AC includes cleaning and inspecting the machinery, as well as replacing the filter and mending any worn-out or broken parts.

4. What Size Air Conditioner Do I Need?

Finding the proper size of air conditioner for your home is crucial for achieving comfort and efficiency. Here are some points to take into account when deciding what size air conditioner is right for your home:

  • Square footage: The size of the space you have to cool is one of the most important factors. Larger spaces require more cooling power.
  • Home insulation: Well-insulated homes hold cool air better, which should minimize your cooling needs.
  • Climate: If you live in a hotter climate, you'll need a more powerful air conditioner compared to a homeowner living in a cooler environment.
  • Number of windows: Windows often let in heat, in particular when they're south-facing or not well-insulated.
  • Number of people: More people in the house means more body heat, which can affect your cooling needs.
  • Present HVAC system: The size and productivity of your current system can provide a starting point for determining what you need.

Because the size of your cooling system is so critical to your home’s comfort, you will almost certainly want a professional opinion. At Childress 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 design and size.

5. What Does My Air Conditioner Cost?

While prices differ depending on the brand of the unit and your home’s unique specifications, a new air conditioning system generally costs between $5,000 and $12,500 to purchase and install. On the plus side, a benefit of air conditioning replacement is that new air conditioners are developed to be extremely efficient, so they do more with less power when compared to older units.

The price tag 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 in addition to federal regulations that can impact the design.

Note these are average costs and prices can vary. It's always helpful to get at least a few quotes from trusted HVAC companies before making a choice.

6. Why Is My Air Conditioner Freezing Up?

Air conditioning freezing up can be due to a variety of factors, all of which boil down to the system's inability to efficiently transfer heat. If your AC is experiencing issues causing it to freeze up, it is very likely time for air conditioning repair.

Here are some typical triggers for AC freezing up:

  • Poor airflow: If the air isn't flowing easily through your AC system, it can't sufficiently absorb heat. This could be due to a clogged air filter, obstructed return air ducts or a failing fan.
  • Low refrigerant levels: If your air conditioner is getting low on refrigerant, it may become too cold and freeze up. This is usually because of leaks in the refrigerant lines.
  • Very Chilly outdoor temperatures: Running an air conditioner when it's too cold outside can cause the system to freeze. Most units aren't designed to operate in temperatures below 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.
