7 Signs You Need to Call an HVAC Technician

May 22, 2024

Staying comfortable at home is essential, and your HVAC system plays an important role in that. Unfortunately, like most other mechanical systems, your HVAC system can develop issues over time which could lead to costly repairs if left unchecked. To prevent this from happening, we’ve put together some of the key warning signals you should look out for so you can call an experienced technician before bigger problems arise – ensuring your home stays cozy all year long.

1. Strange Sounds

If you hear unusual sounds such as grinding, rattling, or banging coming from your HVAC system, it may be a sign of a problem with the internal components. An HVAC system typically emits familiar noises as it operates, such as the hum of the fan or the clicks of the thermostat adjusting temperature settings. However, any new or unfamiliar sounds coming from the HVAC unit could signal a malfunction that requires attention.

Being aware of the usual sounds your system produces and listening for any deviations can help alert you earlyon to potential issues, allowing for prompt repair and avoids more extensive damage or inefficiencies.

2. Little to No Airflow

This is probably the most obvious sign when it comes to understanding when to call a professional. An HVAC unit that fails to effectively push air out likely suffers from one or more mechanical issues requiring attention. While routine maintenance like cleaning air ducts or replacing filters can resolve some problems, a unit’s inability to adequately push air out often points to a more serious concern, such as a faulty compressor.

In these situations, it is best to enlist the help of a professional HVAC technician to properly diagnose and repair the problem to avoid risking permanent damage to the unit or wasted time and money on ineffective DIY solutions.

3. Uneven Heating or Cooling

Is your house feeling unevenly heated or cooled? If so, it could indicate a problem with your HVAC system’s airflow or ductwork. Get ahead of potential issues by paying attention to this signal.

4. High Energy Bills

During certain seasons, it’s expected that your energy bills will rise on a steady incline. Be on the lookout for an unusually high spike, which could indicate there’s something wrong with your system. Simple adjustments to things like thermostats can help improve efficiency and lower those rising prices, but it might require further investigation for issues such as clogged filters or refrigerant leaks, which won’t go away without repair. Not taking care of these problems carries more than just financial risk, it has potential to cause permanent damage to the unit.

5. Poor Air Quality

Poor air quality can cause a variety of health problems, so it’s important to pay attention if you notice an uptick in the amount of dust or other particles floating around. This could be due to an issue with your HVAC system’s filter or ducts that need attention.

6. Foul Odors

During the summer months, a malfunctioning air conditioner can raise indoor humidity levels and encourage the growth of mold, mildew, or even musty odors. In wintertime be aware: if you detect gas fumes or burning scents it could be due to wiring inside the system burning. In this case, it’s crucial to call a technician as soon as possible.

7. Age of System

In general, if your HVAC system is more than 10-15 years old, it may be time to call a technician for a system checkup, as older systems may not be as efficient as newer models and may require more maintenance.

Final Thoughts

Overall, it’s important to be aware of the signs that indicate the need for a HVAC technician. As soon as you notice any of these issues, it is important to investigate further and schedule an appointment with a qualified technician

Keeping up with regular maintenance and having an annual tune-up plan can help prevent malfunction and extend the life of your HVAC system.
