Woman-warm-and-sweaty-from-heatIt’s every homeowner’s worst nightmare.

The temperature is skyrocketing and your air conditioner isn’t blowing cold air.

Unless you’re able to figure out what the problem is and have it fixed quickly, things are going to get sticky and uncomfortable really quickly.

Don’t spend any more time feeling miserable: let’s walk through the list of things you can do to get the cold air blowing again.

1. Is Your Thermostat Set Correctly?

Often the thermostat is the culprit behind an uncooperative air conditioner.

If your thermostat is set a higher threshold, it might not actually be turning on. For example, if it’s 24°C, and your air conditioner is set to 28°C.

It might also not be cooling if it’s on the ‘Auto’ setting instead of ‘On’.

At this point, you’ll have to do a little investigating. First: have you made sure the air conditioner shut-off switch (located in the shut-off box) is flipped? Have you checked the breakers to make sure nothing has tripped?

Once you’ve established that, you should reset your thermostat, and program the temperature to a few degrees cooler than the house.

For example, set it for 20°C if your home is registering as 25°C. This way you’ll be able to notice a change.

It will take a few minutes to feel any cool air, so don’t panic if you don’t notice it right away.

Once you’ve waited, stick your hand over vents to see if you can feel the cold air. Chances are a simple reset was all you needed.

If you still don’t feel any cold air, there could be an internal wiring problem, causing the malfunction. In this case, consult a professional about next steps.

2. Have You Been Changing Your Furnace Filter?

You might not think your filter contributes to your AC not blowing cold air, but it does.

If you haven’t been regularly checking and changing your air filter, it’s most likely extremely clogged.

A clogged filter will restrict air flow into your home. This means that you won’t only notice a lack of cold air, but probably a little more dust and an overall stuffiness.

We recommend checking your filter every 30 days, and changing/cleaning it as needed. You can find out more here >

3. Is Your Condenser Dirty?

The outdoor part of your air conditioner is called a condenser. When dirt and debris get in there, it interferes with the process.

Your air conditioner will have to work much harder to pull in air and cool it. It’s very similar to the problem you’ll experience with a clogged filter.

Luckily, cleaning up your condenser is something you can do on your own – but you have to be very careful not to bend of break anything.

We recommend using soap and water to gently wipe away the dirt. You can also use a hose with a gentle pressure.

To minimize dirt and debris in the future, invest in a good weatherproof cover for when your air conditioner is not in use. You should also keep the area around the condenser weeded, trimmed, and clear of overhanging branches and other plants.

4. Are There Mechanical Problems?

Air conditioners experience normal wear and tear over time, like most things. This means it may experience a mechanical issue at some point during its life.

If your air conditioner isn’t operating as usual (or at all), and you’ve checked your thermostat and filter, you should contact us immediately to examine the inner workings of your system.

5. Is There a Refrigerant Leak?

Refrigerant is cycled between the outdoor and indoor air conditioner units, compressing and expanding as it does. You should never have to replace it, or top it off, because it never runs out.

But when a refrigerant leak occurs, there’s not enough of it to effectively absorb heat. You’ll therefore notice a decrease in cool air.

There are a few ways to identify a refrigerant leak:

  • You’ll hear a hissing noise while your air conditioner is on.
  • There will be icy buildup on your air conditioner.
  • If it’s still blowing cold air, it will take an extremely long time to cool your home, causing your air conditioner to run for much longer periods of time.

If you find a leak, or suspect you have one but aren’t sure where to look, stop using your air conditioner right away and get in touch with us.

Important: If you do have a refrigerant leak, you should not try to fix it yourself. This repair process takes specialized training, and should always be left to professionals.

6. Have You Had Your Annual Maintenance?

Many homeowners think annual maintenance isn’t necessary.

These are the same homeowners who wind up with surprise breakdowns, costly repairs, and no air conditioner on the hottest days of the year. And in the GTA, that’s pretty much every day from mid-June to late-September.

7. Is Your AC the Right Size?

An air conditioner that is too big or too small will wear out your air conditioner, and cause a whole bunch of problems. This includes no cold air.

We have a comprehensive guide on air conditioner sizes that you can find here >

Unfortunately, this is an issue that will continue unless you replace your air conditioner. If this is an option for you, we can help make sure you get the right air conditioner the first time.

If replacing your air conditioner is not possible at this time, talk to us about setting up regular maintenance appointments. We might not be able to completely solve your problem, but we can do our best to keep you cool and comfortable.

8. Is There a Leak in Your Ductwork?

This is a little harder to diagnose, but could be costing you both cold air and money.

A leak in the ductwork means that the cold air is being filtered out into the walls before it reaches the vents.
