What to Do When Your AC Keeps Running

The hotter the Arizona temperature, the harder your air conditioner will have to work to keep you cool. If your unit constantly runs and never turns off, there may be a bigger issue. A running A/C can lead to high monthly energy bills and damage your unit.

If your AC is constantly running, don’t panic! It could be an easy-to-fix issue and not a significant maintenance problem. Read more on the most common reasons why your air conditioning C keeps running.

Most common AC Issues and How to Troubleshoot

If these troubleshooting steps do not resolve the issue, it may be a more severe problem that requires professional repair. It’s always a good idea to have an annual maintenance checkup (such as the MVP Plan) with a qualified technician to keep your A/C unit in good working condition and catch any potential problems before they become significant.

Thermostat problems

Check the thermostat settings to ensure it is set to the desired temperature and is in the “auto” or “cool” mode. If the thermostat is set correctly, but the AC continues to run, it may be malfunctioning and will need to be repaired or replaced.

Dirty air filter

A dirty air filter can cause the air conditioner to work harder than it needs to, which can cause it to run continuously. Check the air filter and replace it if it is dirty. Follow these steps to ensure your filters are cleaned properly:

1. Turn off the air conditioner: To avoid any electrical mishaps, turn off the air conditioner and unplug it from the power source before cleaning the air filter.
2. Find the air filter: On your air conditioner, remove the filter. Usually, the filter is placed close to the air intake vent. Carefully remove the filter from its housing.
3. Vacuuming or washing the filter will effectively clean it: To clear any dust or debris, use a vacuum cleaner attached with gentle bristles. Use water and a light soap to wash the filter, and then scrape it with a gentle brush. Before reinstalling the filter, rinse it and let it air dry.
4. Reinstall the filter: Put the filter back after it has dried. Make sure the filter is properly inserted and firmly fastened.
5. Start the air conditioner: Make sure the filter is clean and securely fastened. If you have pets, allergies, or live in a dusty area, you should clean or change your air filter more frequently.

Low refrigerant levels

If the refrigerant levels in the A/C are low, the unit may run continuously to cool the room. A qualified technician must check the refrigerant levels and add more if necessary.

Dirty condenser coils

Dirty condenser coils can cause the AC to work harder than it needs to, which can cause it to run continuously. Clean the condenser coils to improve the efficiency of the AC. Here are some tips to get your HVAC system to operate efficiently:

1. Turn off the air conditioner: To avoid any electrical mishaps, turn off the air conditioner and unhook it from the power source before cleaning the condenser coils.
2. Access the condenser coils: The external unit provides access to the condenser coils, which are normally found outside the home. Eliminate any obstructions to the device, such as plants or debris.
3. Condenser coil cleaning: To clean the condenser coils, use a soft brush or a brush designed specifically for coil cleaning. As an alternative, you can spray water onto the coils using a hose but be careful not to apply too much pressure because this could harm the coils or fins. The coils can also be cleaned using a specific coil cleaning solution.
4. Straighten any bent fins: Use an AC fin comb or a soft brush to clean the fins. Airflow might be affected by bent fins, which can reduce the effectiveness of your AC unit.
5. Reassemble the unit: After cleaning the condenser coils and fins, put the external unit back together and turn on the air conditioner. Make sure there is smooth airflow.

Blocked airflow

Blocked or restricted airflow can cause the A/C to run continuously. Ensure all vents and registers are open and not blocked by furniture, curtains, or other objects.

When to consult a Chas Roberts professional

If none of these solutions solve the problem, it may be a more serious issue with the air conditioning unit itself, and a qualified technician will need to diagnose and repair the problem.

Remember to ensure that your air conditioning system continues performing at its best. It’s crucial to do routine maintenance on your equipment. At Chas Roberts, we help with the smallest and biggest issues if you need assistance. 

Why is it important to have a functioning AC unit in Arizona?

In Arizona, where temperatures frequently soar to dangerous levels, it’s crucial to have a functioning AC unit to minimize the risk of heat-related health issues. Keeping cool and hydrated by seeking out shaded or air-conditioned locations, consuming plenty of water, and avoiding strenuous activity during peak heat hours are all important.

As summer approaches, it’s critical to avoid being trapped in the sweltering heat without a functioning AC unit. Here are some health hazards linked with a lack of air conditioning:

Not having a working AC can lead to the following:

• Heat exhaustion
• Dehydration
• Respiratory problems
• Poor sleep

Extreme heat

Arizona is known for its sweltering and dry climate, with temperatures often exceeding 100 degrees Fahrenheit in summer. This heat can be dangerous, especially for vulnerable populations such as older adults, young children, and those with certain medical conditions. Air conditioning helps to keep indoor spaces relaxed and comfortable, reducing the risk of heat-related illnesses.

Indoor air quality

Air conditioning can help to improve indoor air quality by filtering out pollutants such as dust, pollen, and allergens. This is especially important in Arizona, where there are high outdoor air pollution levels and allergens such as pollen from desert plants.

Energy efficiency

While running an air conditioner can use a lot of energy, using an energy-efficient unit can help to reduce energy costs and minimize the environmental impact. Many newer air conditioning units have high SEER (Seasonal Energy Efficiency Ratio) ratings, which means they are designed to be more energy efficient than older models.

Home value

In Arizona, air conditioning is considered an essential feature of a home, and many homebuyers expect to have a functional air conditioning system in place. A high-quality air conditioning system can help increase a home’s value and desirability.

Having an air conditioner in Arizona is important for keeping indoor spaces cool and comfortable, improving indoor air quality, reducing energy costs, and increasing home value.
