As one of the best companies servicing heating, ventilation, and air conditioning (HVAC) systems in Ohio, we can tell you just how important this home system is. It controls everything from the heating and ventilation to the air conditioning — and when it fails, it can cause comfort and safety issues. So it’s worth knowing the signs of a system having issues and measures you can take before calling in the professionals.
Signs of an HVAC System Failure
The sooner you spot the signs of an HVAC system failure, the sooner you can take action. Here are some common warning signs that your system may be on the brink of failure:
- Strange Noises: If your HVAC system is making unusual sounds like grinding, squealing, or banging, it’s a sign that something isn’t functioning properly. These noises could indicate worn-out parts or a malfunctioning motor.
- Lack of Heating or Cooling: The most obvious sign of HVAC failure is the inability to produce the desired temperature in your home. If your system isn’t warming or cooling the air, it’s time to investigate.
- Inconsistent Airflow: If you notice some rooms are hot while others are cold or if airflow is weak from your vents, this could be a sign of ductwork issues or a failing blower fan.
- Strange Odors: Foul or musty smells coming from your HVAC system may signal mold growth in the ducts, an electrical issue, or a problem with the system’s components.
- Increased Energy Bills: A sudden spike in your utility bills can indicate your HVAC system is working harder than usual to maintain the temperature. It could be struggling due to inefficiency, leading to higher energy consumption.
- Frequent Cycling: If your HVAC system constantly turns on and off or short cycles, it’s a sign it is struggling to regulate the temperature efficiently. This could point to many issues, including a clogged filter, malfunctioning thermostat, or low refrigerant levels.
What to Do When the HVAC Fails
When you notice any of the above signs, you should do the following to prevent further damage and ensure your system gets back on track:
- Turn Off the System
If you notice any unusual noises, smells, or signs of a malfunction, turn off your HVAC system to prevent further damage. Continuing to run a system experiencing issues can lead to more severe problems and potentially costly repairs. - Check the Thermostat Settings
Sometimes, the solution is as simple as checking your thermostat settings. Make sure it’s set to the right temperature and the system is in cooling or heating mode as needed. If the thermostat is unresponsive or malfunctioning, try resetting it or changing the batteries. - Inspect the Air Filter
A clogged air filter can cause poor airflow and lead to system failure. If your HVAC system struggles to circulate air, check the filter and replace it if it’s dirty or clogged. Depending on usage, it’s recommended to change filters every one to three months. - Ensure the Circuit Breaker Is On
Your HVAC system is powered through an electrical circuit, and sometimes, a tripped breaker can cause it to stop working. Check the circuit breaker panel to ensure the HVAC breaker hasn’t tripped. If it has, reset it and see if the system starts functioning again. - Clear the Area Around the HVAC Unit
If you have an outdoor unit, check for debris, leaves, or snow that might obstruct airflow. Ensure the area around your HVAC system is clear so it can operate efficiently. - Call a Professional Technician
When you’ve taken the initial steps, and the problem persists, it’s time to call in a professional HVAC technician. They have the expertise and tools to diagnose and repair the issue safely. Regular professional maintenance can also help catch potential problems before they become major failures.
