Air Conditioner Troubleshooting: 7 Common Problems

air conditioner troubleshooting

Air conditioning (AC) systems are an important part of our lives, providing comfort during hot summer days. Despite their reliability, AC units occasionally develop issues that can hinder optimal functioning. 

While many challenges require an AC repair from professionals such as Armstrong Plumbing, Air & Electric, there are problems that some homeowners may be comfortable tackling on their own. We will discuss several common problems you may be having and some air conditioner troubleshooting tips.

Seven Common AC Issues & Basic Air Conditioner Troubleshooting Techniques:

1. Reduced Cooling Capacity: A common complaint is the AC is not providing adequate cooling, possibly due to low refrigerant levels. The refrigerant is the substance your air conditioning system uses to remove heat from the air. If the system is low on refrigerant, it will not cool effectively. An Armstrong HVAC technician should handle refrigerants due to the technical and environmental considerations involved. Schedule an AC repair today.

2. Clogged Filters: Over time, dust and dirt can clog filters, reducing the AC’s efficiency. Regularly cleaning or replacing the filters can solve this problem, improving air flow and performance. With Lubbock’s dusty environment, Armstrong recommends changing air filters every 30 days for the highest efficiency.

3. Thermostat Issues: If your AC is not turning on or is not reaching the desired temperature, the thermostat may be the culprit. Make sure the thermostat is set to the right temperature and in cooling mode. If the issue persists, the thermostat may need to be replaced.

4. Drainage Problems: The condensate drain line can get blocked due to dust and dirt over time, causing water leakage and potential damage to the AC system or area around the unit. Clearing the drain line usually fixes this issue. A DIY solution of vinegar and baking soda may work, but if you want to leave the task to a trained HVAC technician, better call Armstrong!

5. Electrical Problems: AC systems have complex electrical systems. Problems with the wiring, circuit breakers or fuses can cause the system to malfunction. If you suspect an electrical issue, it is best to call an Armstrong electrician for safety reasons.

6. Unusual Noises: Grinding, squealing or banging noises can indicate something is wrong inside the unit, such as loose parts, a lack of lubrication or a failing motor. A thorough AC inspection and repair can fix these issues.

7. Frequent Cycling: If your AC system is frequently turning off and on, the AC system could be too large for your home. Frequent cycling is inefficient and increases wear and tear. One of Armstrong’s experienced Comfort Specialists can assess your home’s layout and size to determine the appropriate unit for your space.

While you can troubleshoot minor issues, a professional should be consulted for complex problems. Regular maintenance can help avoid most AC problems and keep your system functioning properly.
