Things to Do Before Turning On Your Air Conditioner for the First Time

Air conditioners can now be effortlessly operated from anywhere using wi-fi and other smart technologies that come with new models. However, you must be aware that AC units need to be cared for, as they are prone to malfunctioning if not utilized as per instructions. Since the summer temperature and heat waves are soon to be upon us, soon you may need to turn on the AC in homes and commercial buildings. A new air conditioning system installation may be required because there are possibilities of issues like:

  • Compressor damage 

The compressor is an essential component of an AC unit, and when it is not used for an extended period, the inside mechanical parts can become stuck, causing damage to the compressor. If the compressor is damaged, it may need to be replaced.

  • Mold and mildew growth 

When an AC unit is not used, moisture can accumulate inside the unit, leading to mold and mildew growth. If the mold and mildew are not removed, they can cause a musty smell and affect the quality of the air. When this gets too severe, it may not be able to be cleaned and corrected.

  • Clogged air filters

If the AC unit’s air filters are not cleaned regularly, they can become clogged with dust and debris, reducing the unit’s efficiency and causing it to work harder than necessary. This can lead to a failure.

  • Refrigerant leaks

Refrigerant is the substance that cools the air inside an AC unit. At time, the refrigerant can leak out of the system, resulting in reduced cooling capacity. This can make the system stop working or become damaged due to the compressor failing.

Some problems can be addressed with your personal efforts whereas others may require the expertise of HVAC Contractors. On the basis of professional HVAC engineers’ suggestions, we are listing 6 considerable factors before turning on your AC after a long time.

6 Things to Do Before Turning On Your Air Conditioner for the First Time 

Turning on your air conditioner for the first time after a long period of disuse requires some preplanning and careful consideration. Here are some things to do before turning on your air conditioner:

Clean/Replace the Air Filters

Dirty air filters can reduce the airflow and cause your air conditioner to work harder than necessary, which can lead to increased energy consumption and reduced cooling efficiency. Before turning on your air conditioner, you should check and clean or replace the air filters, depending on their condition. Cleaning the air filters is a straightforward process and involves removing the filter, washing it with water, and letting it dry before reinstalling it. If the filters are too dirty or damaged, you may need the help of heating and cooling system repairs or replacement technicians.

Inspect the Outdoor Unit

The outdoor unit of your air conditioner can accumulate dirt, debris, and other objects, such as leaves and twigs, during the off-season. If the outdoor unit is clogged, it can reduce the unit’s efficiency and cause it to work harder than necessary. Before turning on your air conditioner, you should inspect the outdoor unit and clean any debris that may have accumulated around it. Use a garden hose to wash away dirt and debris from the unit’s fins and coils, being careful not to damage them.

Check the Electrical Connections

Checking the electrical connections of your air conditioner is an essential part of prepping the unit for the cooling season. Over time, the electrical connections can become loose, corroded, or damaged, which can affect the unit’s performance and safety. Before turning on your air conditioner, ask an air conditioner maintenance expert to inspect electrical connections and tighten any loose screws or nuts. If you notice any signs of damage or corrosion, it may be necessary to replace the affected parts.

Clean the Condensate Drain Line

The condensate drain line is a pipe that removes the condensation from your air conditioner’s evaporator coil. Over time, the condensate drain line can become clogged with dirt, debris, and algae, which can cause water to back up into the unit and damage it. Before turning on your air conditioner, cooling system installations experts can inspect the condensate drain line and clean it using a wet/dry vacuum or a pipe cleaner.

Inspect the Refrigerant Lines

The refrigerant lines of your air conditioner are responsible for circulating the refrigerant between the indoor and outdoor units. Over time, the refrigerant lines can become damaged, corroded, or the joints can deteriorate, which can cause refrigerant leaks and reduce the unit’s cooling capacity. Before turning on your air conditioner, you should inspect the refrigerant lines and ensure they are in good condition. If you notice any signs of damage or corrosion, it may be necessary to replace the affected parts.

Schedule a Professional Tune-Up

While the above steps are crucial for maintaining your air conditioner’s performance and efficiency, it is also recommended to schedule a professional tune-up before the start of the cooling season. A licensed air conditioner maintenance technician can inspect and service the entire system, including the compressor, evaporator coil, blower motor, and other components, to ensure they are in good working condition. A professional tune-up can help identify any potential issues before they become major problems and ensure your air conditioner is operating safely and efficiently.

Before turning on your air conditioner for the first time after a long period of disuse, it is essential to take these preplanning steps to ensure the unit is in good working condition. Seek air conditioning installation and repair experts’ assistance wherever needed because your intend to save a few bucks may cost unexpectedly huge later!
