Indicators for When It’s Time to Schedule Ducted AC Service

Ducted AC service is keeping your whole-home air conditioning system running well. This kind of service helps make sure the air flows nicely and the system doesn’t use too much electricity.

It’s important because it keeps your home cool without high costs. If an AC unit gets too old, usually over 10 years, or starts to work poorly, like making loud noises or smelling bad, it might need to be checked by a professional.

Experts like Preferred Home Services suggest checking your AC at least once every year. They know what they’re doing because over 2,000 customers said they did a great job. To keep your home comfortable and stop small problems from getting big, you should know when to call for help with your ducted AC.

In this article, we’ll tell you about signs that mean it’s time for service. We talk about things like why high bills are bad news and what weird sounds could mean. Keep reading to learn how you can spot these signs in your own home!

Recognising the Indicators for AC Service

Recognising the indicators for AC service is critical in maintaining an efficient and reliable air conditioning system. Be alert to signs such as a spike in your energy costs or odd sounds coming from your unit, which may signal that it’s time to call a professional HVAC technician.

Increased Energy Bill

Your air conditioning system might not be as efficient as it used to be if you see your energy bill going up. A high energy bill often means that the AC is working harder than normal.

Dirty filters, blocked air ducts or old equipment can make an AC use more power. You need to call an HVAC technician to check your system.

Fixing problems early helps stop bigger issues later on. Regular cleaning of filters and coils keeps your heating and cooling systems running well. Make sure thermostats are set right too.

These steps may lower the cost of running your air conditioner and keep bills down.

Unusual Noises

If your air conditioning unit starts making strange noises, it’s a clear sign something’s wrong. Banging or grinding sounds often mean parts inside are loose or broken. These noises can come from the blower, fans, or even the outdoor condenser coils.

Ignoring these sounds could lead to bigger problems down the road.

A quiet heat pump should hum along almost silently — not clank and screech. As soon as you hear odd sounds, get an HVAC professional to check your system. They can find out what’s causing the noise and fix it before it gets worse.

Now let’s explore another indicator: insufficient airflow through your vents.

Insufficient Air Flow

Moving from strange sounds, another clear sign your ducted AC needs attention is weak air flow. This can mean your home doesn’t cool down or warm up as it should. Air filters might be clogged, blocking the breeze from moving freely.

Check your vents to see if the air coming out is weaker than usual.

Air conditioners work hard to keep temperatures just right. But without enough air blowing through the system, they strain and use more energy. Preferred Home Services knows this issue well and often fixes it for their 2,000 satisfied customers.

Random Restarts

If your AC unit stops and starts without warning, this could be a sign of trouble. Random restarts interrupt the cooling process and can wear out your system quickly. An air conditioner should run in consistent cycles, but if it’s turning off randomly, several issues might be at play.

It could be something simple like incorrect thermostat settings or more complex problems such as a refrigerant leak or electrical faults.

Getting your system checked by a professional is crucial to prevent damage. They will look at electrical connections, test the thermostat, and ensure that all parts of the HVAC systems are working well together.

Don’t let random restarts go unchecked; they could lead to bigger repairs down the line. Fixing these hiccups promptly keeps your ducted air conditioning units running smoothly and energy-efficiently.

Unpleasant Odours

After dealing with random restarts, it’s essential to also consider the scent coming from your air conditioner. Bad smells could signal big trouble. For instance, a rotten egg smell often points to a gas leak.

This is dangerous and needs quick action. A gunpowder-like scent might mean there’s an issue with the heating and air conditioning system’s electrical parts.

Keeping things clean helps stop bad odours. Clogged filters can trap all sorts of nasty stuff that stinks up the place when your central air conditioner runs. Regular maintenance by professionals like Preferred Home Services can keep your home smelling fresh.

Their team knows how to fix problems causing bad smells so you breathe easy again. Over 2,000 customers trust them for their energy-efficient solutions and reliable fixes for smelly HVAC issues.

Designing an Efficient Ducted Aircon System to Prevent Frequent Services

Choose the right size AC unit for your home. A system too small won’t cool effectively and will run too often, whilst one that’s too big will cycle on and off, wasting energy. Look for an energy-efficient model with a high Seasonal Energy Efficiency Ratio (SEER) rating.

This means it uses less electricity to keep your rooms at a comfortable temperature.

Install proper insulation in your home to help maintain the desired temperature. Seal ductwork to prevent air from escaping, which can cause the system to work harder than necessary.

Plan regular maintenance checks by a professional every year; this keeps things running smoothly and heads off problems before they grow bigger. Use quality filters and replace them regularly to protect the machinery from dust and debris, which can lead to breakdowns or inefficiency.

Remember that smart thermostats can track your heating and cooling habits over time. They adjust automatically for optimal performance without continuous manual setting changes. This not only makes life easier but also helps save on energy costs in the long run since you’re using just what is needed when it’s needed.


Your ducted AC needs regular check-ups to run smoothly. If you notice higher bills, strange sounds, weak air flow, or bad smells like gun powder, it’s time for a service. Quick action can save money and keep your home comfortable.

Don’t ignore these signs; book an expert visit as soon as possible to fix any issues with your system. Keep in mind professional maintenance twice a year keeps your AC efficient and effective for longer.
