Signs Your HVAC System Requires Repairs

Some common signs that your HVAC system needs repairs are:


Increased Humidity: If your HVAC system is functioning correctly, the humidity outside should not affect your property's temperatures. Your air conditioner is responsible for regulating the humidity levels inside your home, and any trouble with it can affect its ability to do so.  


Leaks: Under normal conditions, there shouldn't be any leaks around your HVAC system. Damage to your HVAC equipment can cause the liquids in it to leak, pool on your floors, and seep through your walls. Ignoring the issue can escalate the problem and cause structural damage to your property. 


Abnormal Noises: If your HVAC unit is squealing, scraping, or grinding, contact an HVAC technician right away. It's possible that a belt or other piece of internal hardware has broken or is malfunctioning.


Poor Airflow: If you notice unusually low or high airflow from your air conditioning unit, it may be time to inspect and replace your clogged piping. Most of the time, the problem is with the compressor in the AC unit, but it's also possible that your ducts are to blame. 


Strange Odours: If you can smell a strange odour coming from your vents while your HVAC unit is running, then you may have a problem that requires professional repair. A strong odour could indicate a problem with your unit's wire insulation, and a mildew odour could indicate that mould has begun to grow somewhere in the system.


Thermostat Not Working: The thermostat serves as the command centre for your HVAC system. Your home's HVAC system doesn't know when and how hard to work to control the climate inside your house unless it receives input from a properly functioning thermostat. First, determine whether your thermostat requires batteries.


High Utility Bills: Yes, unusually high electricity bills are also an indication of something being wrong with your HVAC system. In such cases, it is best to call an HVAC expert to get the heating and cooling systems checked out.


If you notice any of these issues with your HVAC system, schedule an appointment with us. Our team can expertly diagnose the problem with your HVAC system and provide a long-lasting solution for it. We know how to work with the most popular makes and models.
