Increased energy costs, lack of airflow, issues reaching a set temperature, and problems maintaining your cooled air are all signs your AC system is in distress. The lack of air conditioning can be uncomfortable, but it can also affect your indoor air quality, increasing your risk of humidity, home damage, and health problems. Thankfully, proper understanding can help address the problem, preventing your AC system from failing or deciding it is time to invest in a new system. Here are a few common reasons your AC system may be failing.
Even if you operate it well and maintain it as recommended, your air conditioning system is not meant to last forever. Basic use over time will reduce its ability to work in the most energy-efficient and effective manner possible.
Most people are surprised to learn the average lifespan of a central air conditioning is between 15 and 20 years. If your system is at, near, or past this average lifespan and it is experiencing signs of distress, it is time to invest in a new system.
Issues with your thermostat(s) may also lead to a complete system failure. When you set the thermostat to the desired temperature, it should cycle on and cool until it reaches your set temperature. If your system is not turning on to start cooling or your home feels warm even though your thermostat is supposedly set to cool, you may need to replace your thermostat.
Cycling on and off again is a common issue with faulty thermostats. This not only prevents your home from reaching and maintaining a cooler temperature but the constant off and on also places unnecessary stress on your system. This extra stress leads to increased energy costs and a possibility that the entire system will fail and need to be replaced.
Replacing an old thermostat may be able to save your system to ensure your home is properly cooled.
Maintenance will not cause your air conditioning system to fail, but insufficient maintenance will.
Maintenance may include a variety of tasks that you can do, such as replacing the batteries in your thermostat and changing the system's filters regularly.
Scheduling a routine cleaning of your outdoor units is also wise. HVAC contractors will inspect the outdoor units, making sure all components are in good working condition, before cleaning out any debris that may be preventing airflow. Inspecting and repairing the ductwork may also be necessary.
