Common HVAC Problems and How to Fix Them

December 14th, 2023

When it comes to HVAC systems, there are several common problems that can arise. Here are some of the most frequently reported issues and their potential solutions:

1. Air Conditioner Not Functioning at All

If your air conditioner has completely stopped working, it could be due to various reasons such as overwork or lack of regular servicing. It’s important to address this issue promptly to avoid temperature swings and potential flooding .
2. Loud HVAC Operation

Unusual noises coming from your HVAC system, such as squealing or screeching, can indicate that it’s working harder than it should be. This could be a sign of a failing air conditioner and may require professional attention .
3. Poor Airflow

Poor airflow from the vents can be caused by issues such as dirt, buildup, or debris blocking the outside unit’s fans. Regular maintenance and cleaning can help address this problem.
4. Malfunctioning Thermostat

A faulty thermostat can lead to temperature inconsistencies and discomfort. Replacing the thermostat or recalibrating it may be necessary to resolve this issue.
5. Tripped Circuit Breaker or Blown Fuse

If your HVAC system is not receiving power, it could be due to a tripped circuit breaker or blown fuse. Checking and resetting the circuit breaker or replacing the blown fuse can help restore power to the system .
6. Dirty Filters

Dirty filters can restrict airflow and reduce the efficiency of the HVAC system. Regularly replacing or cleaning the filters is essential for optimal performance.
7. Refrigerant Leaks

Low refrigerant levels due to leaks can affect the performance and efficiency of the air conditioner. It’s important to have a trained technician fix any leaks, test the repair, and recharge the system with the correct amount of refrigerant .
8. Electric Control Failure

The compressor and fan controls can wear out over time, especially if the air conditioner frequently turns on and off. Checking electrical connections and contacts during professional maintenance can help prevent control failures .
9. Sensor Problems

Issues with sensors can lead to common central air conditioning problems. Regular professional service calls should include checking the sensors to ensure they are functioning properly.
10. Clogged Filters

Clogged filters can lead to reduced airflow and system inefficiency. Regularly cleaning or replacing filters can help prevent this issue.
