4 Signs That Your Air Conditioning System Needs a Maintenance Check

websitebuilder • Aug 10, 2021

Air conditioning systems all need occasional maintenance to keep them working as efficiently as possible. By dealing with minor maintenance issues when you notice them, you might be able to avoid expensive repairs in the future. Watch out for these signs that your air conditioning system needs a maintenance check and call a local HVAC service if you notice any of them.

1. Insufficient or slow cooling

If you notice that your air conditioning system is not performing as well as it used to, leaving you sweating on hot days or waiting ages for your home to heat up in winter, then you should schedule a maintenance check to find out what the problem is. First, check the temperature settings to ensure that the problem is with the air conditioning system and not simply with the settings you have chosen.


For ducted systems, tears in the ducts or ducts that have come loose can cause insufficient cooling or heating by allowing cold air to leak out of the system into the attic or crawl spaces in your home. Another possibility is that the condenser has developed a fault that prevents it from adequately cooling the air in the first place. A local HVAC service can diagnose the problem and let you know what they need to do to fix it.

2. Soaring energy costs

If the amount your household spends on electricity is going through the roof in summer or winter, then a fault in your air conditioning system could be to blame. Poorly maintained air conditioners often use a lot more electricity than systems that are in good condition.


Scheduling a tune-up for your air conditioner could help you to save money over the long term. HVAC technicians can change the filters, clean the unit, replace any damaged parts, and generally restore your air conditioning unit to efficient operation, which should reduce the amount that your household spends on electricity each month.

3. Foul odours

If there is a bad smell coming from your air conditioning system while it is running, then that is a clear sign that the unit requires maintenance. It could be that a fault in one of the key components is creating a damp environment inside the unit, leading to the growth of mould. Another possibility is that some small creature has gotten inside the air conditioning unit and died.


In contrast, an air conditioning unit that smells like burning likely has a part that is wearing out. Continuing to use a unit that smells this way could result in it breaking down completely, so it is best to seek help as soon as possible.


Rather than trying to deal with the unpleasantness of a smelly air conditioning unit yourself, call an HVAC service. Technicians have experience in dealing with all kinds of air conditioning smells and can quickly identify and solve the problem.The body content of your post goes here.

4. Abnormal noises

A well-functioning air conditioning system does not rattle, grind, pop, or bang while it is running. If your system starts to make any of these abnormal noises, you should call an HVAC maintenance service so that they can check over the unit and work out what is causing the sound. It might be that a component inside the unit has experienced excessive wear and tear and is now on the brink of breaking down.
