7 Signs Your HVAC System Needs Maintenance And Repair ─ Few Tips For Homeowners

One fact that every homeowner agrees with is that HVAC system problems occur at the most inconvenient times. It can occur when an extremely hot day or the humidity is at its top. A properly well-maintained, functioning air conditioning system is vital to your and your family’s comfort and health.

And with regular maintenance and service, you can ensure your system is properly working. It is better to identify the small issues and repair them as soon as possible before they become something big. That is why it is important to always go to a reliable service provider.

When looking for repair services, the HVAC service software is the best way to schedule the services with ease and utmost accuracy.

So, look out for the following signs, and if you see any of these, it is time to go for repair.

1. If Your AC Is Making Unusual Noises

One of the signs that your AC unit requires servicing is if you hear any unusual noises. If you are hearing grinding, squealing, grating, or any other unusual noises that you did not hear in the past, then it is a sign to get it checked. These strange noises may mean there are loose parts, which could cause heavy damage to your HVAC unit.

Also, if you are hearing a humming noise, it could be due to some issues with the fan motor. A loud buzzing indicates that the compressor is malfunctioning or may have loose wiring issues. Loose wiring is a fire hazard, so do not delay.

2. The Thermostat Is Not Working Properly

The primary command center of your system is the thermostat. Do you know how the thermostat works? It communicates with your air conditioner and lets it know how much cold air it must generate. It also takes measurements to ensure that the AC is doing its job. How do you know the thermostat is not working? If your AC runs for smaller periods and shuts itself off, or if it is not working at all, then there is a high chance that the problem is with the thermostat.

3. If You Notice Less Air Flow

When you switch on your air conditioning unit and notice that the airflow is minimal, or if there is none, it is time for you to schedule a tune-up. When there is poor airflow, it indicates several issues, so it is best to opt for a technician who can check out and pinpoint the exact cause. The filter may be clogged, or the unit fan is not working, and it can be anything.

4. If You Face Recurring Repairs

Sometimes, your system might not break down at once. Instead, you face small issues over time, and the problems might be repaired themselves. However, they might occur at a later date too. So, if you are experiencing recurring repairs for your HVAC, then there is a possibility that the system is failing.

A professional technician, such as those from CW Service Pros offering HVAC service, can assess the situation and guide you on the right course of action.

If you see water leakage, it is a sign of a fault. Water can leak for several reasons, such as dirty evaporator coil, clogged drains, broken pipes, etc. Also, when you spot a leak, it could mean that there is a problem with the refrigerant.

Refrigerant is basically a chemical that ensures that the system does not overheat. It also helps in keeping the air cool. So, if the refrigerant starts leaking, the unit will not have enough coolant, which can lead to overheating.

6. If a Foul Odour Is Coming

If you suspect that a foul odor is coming from your HVAC unit, then it means that there is some problem with your air conditioner. A foul odor can be annoying too. The reason behind this can be there is a growth of mildew and mold in the ductwork.

So to remove the mild, you will need professional duct cleaning services. If the odor is of burning metal or plastic, then it indicates that there is some serious malfunction. If that happens, you must turn off your air conditioner and wait for a professional evaluation.

7. If You Have a High-Electric Bill

If, for quite some time, you have been seeing an unnecessary increase in your energy bills, then it might be time to check your HVAC system. When the HVAC system has problems, it consumes more power to provide cool air. And you know, more power consumption means a rise in electricity bills. So, by repairing your HVAC system sooner, you will avoid paying high power bills.
