How To Clean An Armstrong Air Conditioner

One of the things you can do to extend the life of your air conditioner is to clean it when it needs to. As a homeowner, there are many simple things that you may complete without spending a lot of time or energy.

You may prolong the useful life of your air conditioner by following the instructions in the owner's manual with a little proactive effort. Before accessing your unit, be sure to switch off the electricity.

Cleaning The Evaporator Coils

Armstrong has two types of coil cleaning methods. In type 1, you can use a soft brush to clean the coil of dust if you have one. This dust is the form of any particles inside your home.

If you used a HEPA filter, you might need a vacuum cleaner for better dust removal. In addition, with an accelerator gun, you can easily and properly clean the unit's drain pan.

In contrast, a type 2 coil cleaning method is when you cannot clean the coils using the type 1 method. A chemical coil cleaner, which you can purchase at your nearest hardware store, is the ideal cleaning alternative.

Armstrong Troubleshooting Checklist

Your system can operate at its peak performance with routine servicing and maintenance from your qualified Armstrong air conditioner specialist.

However, issues can occur with any equipment before you consult your HVAC dealer. Follow this troubleshooting checklist to see if you can fix the problem before hiring an HVAC technician.

Your Home Isn't Cooling

When your home isn't cooling enough or not receiving cool air at all, this may be due to the following reason:

Trip Breaker

Find the location of your breaker panel. Usually, you'll see it on the nearby interior walls. Check the circuit breaker panel to ensure the circuits are ON.

Also, ensure the disconnect switch, which is essentially close to the heat pump unit or air conditioner, is in the ON position. In this case, you'll need to reset the breaker.

The Thermostat Is OFF

Inspect your thermostat whether it is ON or adequately set. Setting the thermostat to its correct setup will determine your home's overall cooling comfort level.

AC Unit Never Turns OFF

This is due to your thermostat isn't correctly set up. Readjust your thermostat to reduce the energy your heating and cooling system must use depending on the weather.

This will also result in your AC unit not being overworked.

Clogged Air Filter

Check your furnace unit or air handler's filter if it is full of dust and debris. If so, change its filter regularly to avoid clogging and keep running your AC unit smoothly.

Coils Have Frozen Up

Generally, you can look under your indoor unit to see if there is any water damage. Also, search for an icy surface in your indoor coil casing.

To test whether it will defrost, you can switch OFF your thermostat for one to three hours.

Examine the furnace or air handler filter unit clogged with dust and dirt. Check it. Change the filter if necessary. Don't forget to replace your filter about once a month.

Blocked Ductwork

If the blower is working, check your indoor unit to see or hear it. After that, observe the airflow at various vents throughout your home.

In addition, ensuring your ductwork is clean enhances a healthy environment. Especially in commercial ductwork systems, Armstrong states it can reduce the power bills by around 30%.

It can also prolong the life of the HVAC unit.

Realigning Fins

Using your garden hose on a low spray setting, spray the fins from the inside out to clear out any dust and debris that has built up. Avoid applying excessive pressure as this could harm the delicate fins.

You can buy and use a fin comb from your nearest hardware store to realign the fins. However, you can also carefully reposition the fins with a butter knife.

Furthermore, if any of these issues continue after troubleshooting your HVAC unit, please contact your HVAC dealer if you're having trouble fixing it as soon as possible.

When Should You Perform Preventive Maintenance On An Air Conditioner?

  • Consider having routine maintenance for your home's heating/cooling system in the spring/fall.
  • Your AC unit is subject to routine maintenance yearly before summer.
  • Before the winter season, you'll need a schedule servicing once a year.
