As the summer heat intensifies, your air conditioning system becomes your best friend. However, when it malfunctions, it can quickly turn into a source of frustration. Understanding common AC issues and how to fix them can save you time, money, and a lot of discomfort. Fortunately, you can troubleshoot and resolve some of the most frequent AC problems, such as:
1. Dirty Air Filters
One of the simplest yet most common problems is dirty air filters. When filters are clogged with dust and debris, they restrict airflow, causing your AC to work harder and less efficiently. Regularly check and replace your air filters, typically every 3-6 months, depending on usage and the type of filter. This ensures optimal airflow and helps maintain your system's efficiency.
2. Refrigerant Leaks
Refrigerant is crucial for cooling, and a leak can cause your AC to blow warm air or not cool effectively. Low refrigerant levels can also lead to frozen coils and system damage. Detecting and fixing refrigerant leaks requires professional help. If you suspect a leak due to warm air or hissing sounds near the AC, contact our home comfort specialists to locate and repair the leak and recharge the refrigerant.
3. Frozen Evaporator Coils
Evaporator coils can freeze due to insufficient airflow, dirty coils, or refrigerant issues. When coils freeze, they can't absorb heat effectively, leading to cooling problems. To mitigate this issue, turn off the AC and let the coils thaw completely. Check and replace the air filter and ensure there are no obstructions around the indoor unit. If the problem persists, call on our HVAC professionals to inspect the refrigerant levels and the overall system.
4. Malfunctioning Thermostat
A malfunctioning thermostat may not signal your AC to turn on or off at the right times, leading to inconsistent temperatures and comfort levels. If your thermostat is battery- operated, start by replacing the batteries. Also, ensure it's correctly installed and not exposed to direct sunlight, which can affect its readings. If that doesn’t help, one of our service technicians can check or replace the thermostat.
5. Blocked or Leaking Ducts
Air ducts that are blocked by debris or have leaks can lead to inefficient cooling, as air isn’t properly distributed throughout your home. Inspect visible ducts for signs of damage or blockages. Seal any leaks with duct tape and consider professional duct cleaning to ensure unrestricted airflow and maximize efficiency.
6. Frequent Breakdowns and Repairs
If your AC is constantly breaking down or needing repairs, it could indicate an underlying issue or that the system is aging and failing. Regular maintenance checks and annual inspections can help identify and fix minor issues before they lead to breakdowns and costly repairs. Regular maintenance and timely repairs extend the lifespan of your AC and also save you from emergencies in the long run.
7. Rising Energy Bills
A sudden increase in your energy bills often signals that your AC is working harder than necessary due to underlying problems like dirty filters, refrigerant issues, or an aging system. Keeping up with maintenance, checking refrigerant levels, and ensuring the unit is in good condition, can help maintain your AC’s efficiency and keep energy costs in check. If your unit is more than ten years old, consider upgrading to a more energy-efficient model. With a new ENERGY STAR-certified model you can save up to 15% on your cooling costs.
