They say knowledge is power, and that’s definitely the truth when discussing your air conditioner. While complicated repairs are best left to experts, it’s helpful to have a rudimentary understanding of your air conditioner and how to solve common AC issues.

Knowing how your AC works and the typical problems it faces will enable you to handle simple problems without needing to call an HVAC specialist every time. This not only saves you cash on minor service calls, but realizing when to call a professional can help prevent small issues from escalating into major repairs.

Your AC is a fundamental part 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 Des Moines if you're not sure about any aspect of your air conditioner's operation or maintenance.

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

1. How Do I Clean an Air Conditioner?

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

The most significant step you can take on your own is to swap out the air filter in your air conditioner. The filter traps dust, pollen, pet hair and other debris, and removes those impurities from the air circulating in your home. If your AC filter becomes plugged, the air conditioner has to work harder than it really should in order to pull air through the filter. A clean filter removes the airborne debris while still enabling air to flow easily through the system.

Replacement filters are available at most popular home improvement stores, hardware stores or can be ordered from your local HVAC professional. A good way to make sure you get the proper filter is to look at your old one before you head out for the store, 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 hoping to buy something similar.

For comprehensive service of your air conditioner, contact the seasoned professionals like the crew at Kohles & Bach Heating & Cooling to do routine maintenance on your AC. They’ll inspect your system, clean or lubricate parts that require attention and look for worn-out parts and potential issues.

2. How Are the Coils on My Air Conditioner Cleaned?

In addition to ensuring your indoor air conditioner equipment is operating efficiently, it’s important to tend to your outdoor unit. Cleaning the coils on the exterior unit of your cooling system is an easy way to increase 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 lowers the temperature of the refrigerant, which then goes back in your home so it can take in more heat from the air in your home's interior. 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) Take off the top of the outdoor AC so you can reach the insides of the unit. Then, being cautious not to stress any cords or attachments, safely put the top to the side.

3) Put a cleaning solution on the fins, starting 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 brands foaming solutions that are applied with your garden hose.

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

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

3. How Long Can Air Conditioners Work?

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, experts say you should start looking into air conditioner replacement after about 12-15 years.

One of the best ways to get the most mileage out of your system is through AC conditioner maintenance. Routine checkups from Kohles & Bach Heating & Cooling includes cleaning and inspecting the machinery, as well as changing out the dirty filter and fixing any worn-out or broken parts.

4. What Size Air Conditioner Do I Need?

Selecting the proper size of air conditioner for your home is vital for achieving comfort and efficiency. Here are some elements to consider when deciding what size air conditioner to buy for your home:

  • Square footage: The amount of space you need to cool is one of the key factors. Larger spaces demand more cooling power.
  • Home insulation: Well-insulated homes hold cool air better, which could reduce your cooling needs.
  • Climate: If you live 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 often let in heat, especially when they're south-facing or not well-insulated.
  • Number of occupants: More people in the house create additional body heat, which may affect your cooling needs.
  • Current HVAC system: The size and productivity of your current system can provide a starting point for identifying what you need.

Given that the size of your AC is so critical to your home’s comfort, you will probably want a professional opinion. At Kohles & Bach Heating & Cooling, we take the time to fully understand your family’s lifestyle, comfort needs and the many other variables such as your home’s insulation level and size.

5. What Does My Air Conditioner Cost?

While prices fluctuate 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. The good thing is that new air conditioners are designed to be exceptionally efficient, so they do more with less power when compared to older units.

The price of an air conditioner is influenced 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 require modifications to the design.

Know these are average costs and prices can differ. It's always helpful to get numerous quotes from reliable HVAC companies before making a choice.

6. What Causes an Air Conditioner to Freeze Up?

An AC freezing up can be caused by a number of factors, all of which boil down to the failure of your system to efficiently transfer heat. If your AC 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 effectively absorb heat. This could be due to a plugged air filter, obstructed return air ducts or a failing fan.
  • Low refrigerant levels: If your air conditioner is getting low on refrigerant, it could get too cold and freeze up. This is usually a consequence of leaks 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 work in temperatures of less than 60 degrees Fahrenheit (15 degrees Celsius).
  • Mechanical failures: Faulty thermostats, damaged blower motors and issues with the relay or control board can all contribute to an AC unit freezing up.
