Air conditioners work hard to keep your home comfortable, especially during the hot summer months. However, frequent breakdowns or repairs can be frustrating and expensive if not addressed early. Knowing the common culprits behind issues can help you take preventative steps before a minor problem turns into AC repairs in Canton, MA. Here are the top five reasons most air conditioning systems end up needing professional repair.
1. Dirty or Clogged Filters:
One of the most common causes of AC problems is a dirty air filter. When they get clogged with debris and dust, airflow is restricted, causing the system to work harder. This strain can lead to overheating, frozen coils, or even system failure over time. Regularly replacing or cleaning filters, typically every 1–3 months, helps prevent these issues. It’s a simple task that can extend the life of your unit and improve air quality.
2. Low Refrigerant Levels:
Refrigerant is essential for cooling the air in your home. If your AC system is low on refrigerant, it may be due to a leak, which can significantly reduce efficiency and cooling power. Low refrigerant can also cause the compressor to overheat and fail, requiring costly repairs. It’s important to have a licensed technician check refrigerant levels and seal any leaks promptly. This helps ensure your system continues to run efficiently.
3. Faulty Thermostat:
A malfunctioning thermostat can lead to uneven cooling or a system that doesn’t turn on or off when it should. This can be due to dead batteries, faulty wiring, or outdated units that no longer communicate properly with your AC. Upgrading to a programmable or smart thermostat can not only resolve these issues but also improve energy efficiency. Always check thermostat settings before calling for repair.
4. Frozen Evaporator Coils:
Evaporator coils absorb heat, but they can freeze if airflow is limited due to blocked vents or dirty filters. Frozen coils reduce your AC’s ability to cool the air and can lead to a complete shutdown if not addressed. Turning off the system and letting the coils thaw may help temporarily, but a professional should fix the underlying cause. Preventative maintenance after the ductless mini-split installation in Canton, MA, can catch these issues early.
5. Electrical Issues:
Wiring problems, faulty capacitors, or tripped breakers can cause your AC to stop functioning altogether. Electrical issues are not only a common reason for repairs but also a potential fire hazard. Any burning smell or frequent circuit trips should be taken seriously. Only licensed technicians should handle electrical repairs to avoid risk and ensure safety. Regular inspections can help identify these issues before they worsen.
Understanding what causes most repairs allows you to take action early and avoid unexpected breakdowns. Routine maintenance, filter changes, and professional inspections are key to a reliable, long-lasting system. Staying aware of these common issues can save you time, money, and stress in the long run. Be proactive to keep your AC running smoothly all year.
