Common HVAC Problems In Summer

Air conditioning system malfunctions during the unbearable heat of the summer are very common. They often take homeowners by surprise, leaving you sweating the cost of a repair bill. What could be the problem? Your AC system may be down due to one of these common issues.

1. Clogged AC Filter

This is a common reason for service calls. If your system is running, but your home is not cooling properly, check for a dirty air filter. When airflow is obstructed, it makes it difficult for your system to maintain temperature. If left unaddressed, this can lead to a frozen coil and abnormally high energy bills.

2. Improperly Set Thermostat or Tripped Breaker

In these events, your system won’t respond at all. However, this is an easy fix, requiring the simple flip of a breaker and verification of proper thermostat settings.

3. Faulty Thermostat

If your HVAC system keeps running long after your home has reached temperature, you could have a faulty thermostat. This problem is common with old, non-programmable thermostats. A knowledgeable AC technician will be able to recommend a compatible alternative in your price range.

4. AC Capacitor Burnout

The capacitor stores energy needed to operate the AC compressor. Your system has two capacitors – one to start the system and the other to run it. If either burns it, your air conditioner will no longer function. It is dangerous to check or manually replace a capacitor, as these devices store electricity. Always leave this job to a pro!

5. Clogged Drain Lines

Clear drain lines are crucial to maintaining proper humidity levels within your home. As moisture is filtered out of the air by your system, it is collected and shuttled out of your home via the drain lines. If they become clogged with dirt, mildew, mold, or algae, water could backflow inside your system, possibly damaging other AC components. A wet-dry vacuum is an easy way to clear blockages from clogged drain lines, and can save you the cost of emergency repairs.

6. Refrigerant Leaks

Refrigerant is an essential component of your air conditioning system, absorbing heat and facilitating the cooling and dehumidification of air. If your system is struggling to maintain temperature or not cooling your home at all, you may have a refrigerant leak. This is a common problem. It’s not enough to simply top off your system, as costly refrigerant will just leak back out. Finding and fixing the leak before refilling your system is essential to protecting your bottom line – and the environment.
