There are several reasons why your central air unit may have stopped working. Many of these can be prevented by having your air conditioner properly serviced.  Some of the most common reasons your central air stopped working are the following:

1. There is too much refrigerant in the system or there is a low refrigerant charge
2. The condenser coils are dirty and need to be cleaned
3. The system is contaminated
4. Low oil lubricant
5. The suction lines are blocked or are not the right size

You can sometimes prevent further damage by watching for the following warning signs:

1. Strange noises or a shaking system
2. Warm air blowing through the vents
3. Circuit breaker frequently trips

Catching issues before they begin will ensure that your air conditioner continues to run throughout the summer. You don’t want to have to wait for a hot and humid week for a technician to service your unit

After installing ducted air conditioning, it is important to understand how to maintain it so that it will stay efficient year after year. Dust, bacteria, and potential rodent droppings can build up over time without proper care. As that air moves through your air con, you could be polluting the air you breathe in your home. Proper cleaning and service will keep your air conditioner pumping clean, cool air into your home.

You should clean your ducted air conditioning filters at least once every 3-4 months depending on the usage of your system and arrange a Full Comprehensive Service with Quality Air at least twice per year. You can frequently check these common signs that your conditioning units need to be serviced:

• If you seem to get less air-flow from your vents or if the air smells stale or dusty, your vents may be covered in dust or grime. Cleaning them should get your air con back to normal. You should also check the inside of your vent cover for dirt.

• Check the filter. If it is too dirty, it may need to be cleaned or replaced. Your filter is your first defence against pollutants entering into your home and should be replaced frequently.

• If you see dust blowing from your vents, it is a sure sign that it needs an air conditioning service.

Maintaining an air conditioner is a big job. Hiring a professional to service your air con will ensure that it is working properly at the beginning of every summer. A proper technician will do more than clean your air conditioner. They will check several things about your air con to make sure it up to standard and ensure it is operating at it’s highest efficiency.

Often, an experienced technician can identify necessary fixes before they become a problem so that you can avoid costly repairs in the middle of summer.

Technicians will often check or perform the following tasks (you should not attempt these on your own):

• Check the electrical connections and tighten any that have loosened with use

• Flush the drains

• Clean both the evaporator coils and condenser thoroughly

• Check blades and blower wheel for good air flow

• Clean winder debris from the condenser

• Clean the ductwork and make any necessary repairs. While you can access some of the ducting and clean it yourself, a professional will have special tools and techniques to clean the whole thing.

• Check ductwork for moisture. Too much condensation can potentially lead to water damage or mould growth.

• Check the refrigerant charge and ensure that it is correct

• Give a full air conditioning service by inspecting the entire unit and fixing anything that needs to be fixed.

The result of a properly serviced air con will be a more efficient machine that produces cooler, cleaner air throughout our hot Brisbane summers.
