Air conditioners are essential for keeping homes and businesses cool and comfortable during the hot summer. Still, like all mechanical systems, air conditioners can experience problems from time to time.

At All Around Mechanical, we understand the importance of having a functioning air conditioner and the discomfort that arises when it breaks down. That’s why we take pride in providing you with comprehensive AC repair services in Vancouver, WA, and surrounding areas.

Below is information on 22 common air conditioner problems and how to fix them, so you have a better idea of what might be wrong with your AC and how to fix it or decide when it’s time to call an expert.

Dirty Air Filter:

A dirty air filter can decrease the efficiency of your air conditioner, causing it to work harder than necessary and potentially leading to a breakdown. To fix this problem, locate and remove the air filter, clean it or replace it with a new one.

Leaking Ducts:

Leaking ducts can cause a significant loss of cool air, reducing the air conditioner’s efficiency. Locate the leak and repair it using metal tape or sealant to fix this issue. If your house needs new ductwork, contact our professionals at All Around Mechanical to schedule an AC installation in Vancouver, WA, and all surrounding areas. 

Clogged Condenser Coils:

Over time, condenser coils can become clogged with dirt and debris, reducing the air conditioner’s efficiency. Turn the power off to the air conditioner and use a soft brush or a vacuum with a brush attachment to clean the coils.

Low Refrigerant:

If your air conditioner is not blowing cool air, it may be low on refrigerant. A professional should address this problem, as it can be dangerous to handle refrigerant without proper training and equipment. Contact the professionals at All Around Mechanical for reliable air conditioning repair in Vancouver, WA.

Blocked Or Frozen Evaporator Coils:

If the evaporator coils become blocked or frozen, the air conditioner will not be able to cool properly. To fix this problem, turn off the power to the air conditioner and allow the coils to thaw. Then, use a brush or vacuum to remove debris and check for any leaks in the refrigerant lines.

Faulty Thermostat:

A faulty thermostat can cause the air conditioner to blow warm air or not turn on at all. To fix this problem, try recalibrating the thermostat or replacing the batteries if it is a battery-powered thermostat. If these steps do not work, it may be necessary to replace the thermostat.

Dirty Or Clogged Condensate Drain:

A dirty drain can cause water damage and reduce the air conditioner’s efficiency. To fix this problem, locate the drain and use a pipe cleaner or a stiff brush to remove debris.

Worn Fan Belt:

A worn fan belt can cause the air conditioner to make a loud noise and not blow cool air. To fix this problem, a professional must replace the fan belt. Our air conditioner repair team in Vancouver, WA, can help you with this.

Strange Noises:

Strange noises coming from your air conditioner can signify a problem that needs to be addressed. To fix these issues, check the loose parts and tighten them, replace the worn fan belt, clean the fan blades or condenser coils, and replace worn bearings. 

Worn-Out Compressor:

A worn-out compressor can cause the air conditioner to blow warm air or not turn on at all. To fix this problem, a professional will need to replace the compressor. 

Weird Odor:

If your air conditioning unit emanates an odd odor, it is best to have a professional check-up to prevent further damage and avoid safety hazards. It could be anything from a dead rodent inside your cooling unit to a faulty electrical component, so don’t risk your safety if you’re experiencing this problem. 

Faulty Electrical Components:

Faulty electrical components, such as a damaged circuit board, can cause the air conditioner to malfunction. To fix this problem, a professional must diagnose and repair the damaged component. 

Increasing Energy Bills:

If you have noticed your energy bills going higher every month, your AC unit is inefficient. It could be due to a variety of reasons. Try removing anything that restricts the airflow, closing windows and doors, and cleaning the air filters regularly to increase efficiency. If it still doesn’t work, you should replace your AC unit and save money in the long run. Contact us to schedule an AC replacement in Vancouver, WA. 

Blocked Drainage Pipe:

A blocked drainage pipe can cause water to leak from the air conditioner. To fix this problem, locate the line and clear any obstructions.

Faulty Capacitor:

A defective capacitor can cause the air conditioner to blow warm air or not turn on at all. Our professional must diagnose and replace the defective capacitor to fix this problem.

Incorrectly Sized Air Conditioner:

An air conditioner that needs to be appropriately sized for your space can lead to several problems, including poor cooling and high energy bills. At All Around Mechanical, we offer AC replacement services in Vancouver, WA, so you can rest easy knowing that your air conditioner is in good hands.

Inadequate Insulation:

Insufficient insulation can cause the air conditioner to work harder than necessary, leading to higher energy bills and decreased efficiency. To fix this issue, you can add insulation to the walls, attic, and floors. 

Short Cycling:

Short cycling can cause your air conditioner to work harder than necessary, leading to a decrease in efficiency and an increase in energy bills. If you’re experiencing short cycling with your air conditioner, a professional must look at it as soon as possible. All Around Mechanical offers AC repair in Vancouver, WA, including diagnosing and fixing short cycling problems.

AC Doesn't Turn On:

If your air conditioner doesn’t turn on, it could be due to various issues, such as a tripped circuit breaker, a blown fuse, a faulty thermostat, or a malfunctioning compressor. To fix the problem, check your circuit breaker and fuses and the thermostat and its settings, and if none works, contact a professional for AC repair services.

High Humidity:

High humidity can make your home or office feel stuffy and uncomfortable. It can be caused by issues such as dirty air filters, clogged drain lines, insufficient ventilation, or a malfunctioning air conditioner. To fix this problem, you can check the air filter, clean the drain line, and ensure the vents are open and clear.

Low Humidity:

Low humidity can cause dry skin, nosebleeds, and other health issues. It is often caused by overuse of air conditioners, dry air outside, and poor ventilation. To fix this problem, you can use humidifiers, keep the air conditioner at a higher temperature, and open windows and vents. If the problem persists, contact our experts for AC installation services in Vancouver, WA, and surrounding areas to install a humidifier in your indoor space.

Visible Mold and Mildew Growth:

Visible mold and mildew growth can signify high humidity levels in your home or office. It can also be caused by leaks or condensation in the air conditioning system. To troubleshoot this problem, you can use dehumidifiers, improve ventilation, and address any leaks or condensation in the AC system.
