1. Lack of AC service and maintenance

The most important thing you can do to protect your cooling system is schedule an AC service known as an annual maintenance. Over 90% of all mechanical breakdowns are due to dirt. Dirty coils cannot transfer the same amount of heat as clean coils. With a dirty coil, your AC will run harder and longer causing unnecessary wear and tear on your system. This extra strain on your system may even result in your compressor and/or fan failing. During an annual maintenance, your trained HVAC service technician will clean the coils and perform an important safety inspection. Not only does an annual maintenance and AC service protect your system, but it also gives you peace of mind.

  1. Dirty filter

An easy way to protect your AC is to change your filters frequently. Your filters should be changed every 1 month to 1 year depending on the filter type. Dirty filters block the airflow of your system, which decreases efficiency and can cause higher utility bills. They can also add to dirt and buildup of other important components of your system including the evaporator coil. According to the Department of Energy, you can save between 5%-15% of your AC energy usage just by changing out a dirty filter. Avoid added strain and breakdowns of your system by keeping your filters clean so it can circulate air without blockages.

Filters can be purchased from our office location at 6109 NE Hwy 99 Vancouver, WA 98665. Our office is open Monday through Friday from 8am to 4pm.

  1. Refrigerant leak

Refrigerant is what we call the substance used to transfer heat in refrigeration process. The amount of refrigerant shouldn’t change within your system unless there is a problem.  If a leak develops in your AC’s refrigeration system, you will experience decreased efficiency and increased wear on the system. Your system’s compressor feels the most strain and may fail over time. If you are noticing that your system has trouble cooling, your utility bills are higher and/or there are hissing noises coming from your HVAC system, your AC may have a refrigerant leak.

  1. Condensation issues

Through the refrigeration process, heat is removed from the home and transferred to the outside.  In this process, condensation is formed. One quality of air conditioning is that it dehumidifies your home causing the home to feel more comfortable on the hottest days. Condensation created by your HVAC system must be drained properly.  If the condensation removal system has not been properly maintained, it can result in system damage, home damage and/or health issues if not handled quickly. Water can ruin your insulation, ceiling, and walls. In addition, the presence of water within your duct work can become a breeding ground for mold and bacteria, which will be circulating throughout your home via your HVAC system. During an annual maintenance, technicians clear condensation systems to ensure proper operation and reduce possibility damage caused by your system.

  1. Weak electrical components

Weak electrical components can cause the unit to work harder resulting in more serious failures and breakdowns. During an annual maintenance, your service technician will evaluate and replace with your approval, any weak electrical components. Having a set of trained eyes evaluate your system before the height of hot weather is a fantastic preventive measure. You don’t want to be stuck without AC in your home, especially during a heat wave.
