When To Replace Your Air Conditioning Unit

Mulherin Air Conditioning Services • August 15, 2022

For many people, an air conditioner is necessary for every home. They assist in filtering the air within your home, ensuring that it is clean and healthy, making even the warmest days more bearable.


The air conditioner, like any other appliance in the home, is prone to faults and, in the worst-case scenario, complete breakdown over time. Because most warning signs sent by an air conditioner are subtle, it may not be immediately evident that your air conditioner needs to be replaced.

Unusual smells from your AC unit

Odours that are out of the ordinary could potentially be an indication of a problem. The insulation may have been compromised, the ductwork is infested with mould, or the filter needs to be changed.



If these relatively minor issues are fixed, but the unpleasant odour persists, you might want to consider replacing the entire unit.

Unexpected rise in electricity costs

One of the most common signs that your AC unit needs to be replaced is an increase in your electricity bill. If you've ruled out other potential causes for the spike in costs, such as changes in your home's occupancy or an increase in the price of electricity from your provider, then it's likely that your AC unit is the culprit.


Older units are not as energy-efficient as newer models, so replacing them with a more recent version can lead to significant savings.

It requires significant repairs

If your AC unit is repeatedly breaking down and requiring expensive repairs, it might be time to replace it. Maintenance on the air conditioner should ideally be performed once per year to check for blockages and ensure that it is clean.


In some cases, it can cost less to replace the entire unit than to keep repairing an old one.

The temperature is inconsistent

If you've noticed that the temperature in your home is becoming increasingly difficult to control, it's a sign that your AC unit is struggling. At the temperature you've set, your air conditioner should maintain steady at the specified range.


If you notice that certain rooms or spaces become frigid zones while others don't appear to get any cool air, it could mean that your air conditioner is on its last legs.

A lack of airflow from the AC

If you've ever put your hand in front of a fully functioning air conditioner, you know there should be a significant amount of airflow.


If you notice that the airflow from your AC unit is weak or nonexistent, the compressor isn't working as efficiently as it should. A new AC unit will likely have a stronger compressor to cool your home better. It is probably time for you to purchase a new air conditioning unit.


Get in touch with an experienced HVAC contractor to go through your choices and get the process of selecting a new unit underway.


During the year's warm months, having an air conditioner in good working order is necessary. If you believe it may be time to replace your air conditioning unit, don't hesitate to contact a qualified HVAC technician.


A brand-new air conditioner can remarkably improve your home's comfort level.
