It’s the start of summer, you’re cruising around town pumping some cool tunes on the radio, and you notice you’re not feeling as cool as the latest Bieber EP. Oh no! Your A/C seems to be working but not quite as well as it should be. It could be that your car is running low on refrigerant gas and is in need of an A/C service. Not servicing your A/C is like not servicing your engine, you run the risk of overheating the system and damaging vital components which can end up costing thousands of dollars to replace. Get in now ahead of summer for an A/C service and we’ll make sure you’re back to being cool as ever in no time!

One of the simplest components of your A/C system is also one of the most important in ensuring your system is working efficiently. Just what is this magical item you ask!? It’s the receiver drier aka the filter, and being a filter means it needs to be replaced every two years or any time the A/C system is exposed to air (for example when the compressor or condenser is changed).
The receiver drier contains desiccant (just like that little bag of stuff you find in a shoebox), which removes naturally occurring moisture from the system and filters any debris from the oil and refrigerant.
Eventually the receiver drier won’t be able to absorb any more moisture or filter debris. A filter in this state will cause high side pressure (more on that later) and the excess moisture that mixes with oil will start corroding aluminium components and rusting steel shafts and thermal expansion valve components.
Just be sure to change your receiver dryer regularly, and you're A/C will be happier and healthier than ever!

STOP!!! Back away from that can of sealant now! Sure, it looks harmless enough, because in theory sealant is designed to glide through your A/C system and when it comes into contact with air/the leak, it will harden and form a seal. Oh if it were only that easy... Your A/C system was specifically designed to circulate refrigerant R134a, so sealant (being of a thicker viscosity than our friend R134a) has a tendency to “gum up” the system.

We’ve seen more than our share of A/C systems which have fallen victim to a sealant repair, and believe us, they’re never the same again. We can replace this part or that, but more often than not the damage is so extensive that the entire system needs replacing (sometimes more than once). Suddenly what should have been a quick, cheap fix has ended up being the most lengthy and expensive repair of your cars life.

Moral of the story – Sealant: great in theory, disaster in practice.

If you’re a savvy shopper (and we bet you are!), you’ll be looking at a product in one store, and be comparing that same product in five other stores on your phone. Why? Because it's so easy! You can do the same for your car too, if you have a written quote to get your A/C repaired, why not upload it on our website www.mrcool.com.au or send it to admin@mrcool.com.au. We’ll be sure to beat it and have you driving away cool as a penguin eating a popsicle in no time. All quotes are subject to an inspection (free of charge or course) and we’ll always confirm the price with you before beginning any work.

Well Winter is coming to a close, which means Summer is well on the way! Now is a great time to make sure your A/C is working efficiently, and to pick up some tips on how to use it effectively. 

Frosty fact: In summer, the inside of your car can reach temperatures up to 30 degrees hotter than the outside! What’s more, 75% of this temperature rise occurs within the first 5 minutes! 

When you first get in your car, put all your windows down and turn your fan speed to high. This will blow all the hot air out, bringing the interior temperature of your car down to the exterior temperature. Now it’s time to crank that A/C up, making sure the “recirculation” mode is on so your using already cool air, and not constantly trying to cool hot air. 

Next it’s time to accessorise. Even though I thought my parent’s use of sunshades (those metallic silver things that go on the windscreen) was uncool back in the day, I have a full appreciation for them now that I have my own car. You can invest in one for around $10 and it will not only help to keep your car cool, but protect your dash as well. You can even go one step further and get shades for your windows too! Just remember that if you treat your car’s A/C well, it’ll be sure to return the favour.

You may be aware that your A/C runs on refrigerant gas, but are you aware of what type? In the past, automotive A/C systems have run on refrigerant R12, but this was eradicated in the early 90s due to it's ozone depleting potential. These days all cars leave the factory running on R134a, a gas much friendlier to the environment and to your car. This isn't the only refrigerant gas on the market though, refrigerants such as HyChill can be bought over the counter and unlike R134a don't require a refrigerant handling license, even though it's a flammable substance.

Some technicians may endorse refrigerants other than R134a, but here at Mr Cool it's all we use. Not only is it recommended by your car manufacturer and endorsed by the Australian Refrigeration Council, but it's non flammable, non toxic and much friendlier to the environment than it's counterparts.

Ever wondered about the difference between genuine and aftermarket car parts? If you have (even if you haven't!) take a look at Mr Cool's blog this month, it's got some handy facts to keep in mind next time your car goes in for a repair. Check it out at the link below!

Did you know the A/C compressor is commonly referred to as the heart of your A/C system? That's because it's the driving force which keeps refrigerant gas flowing and all the other parts of your A/C working efficiently. If there's a leak somewhere in the system, the compressor will soon be running dry and quickly overheat, leading to a lengthy and expensive repair. That's why booking in for annual A/C servicing will ensure your system contains the correct amount of gas which will keep that heart pumping!

Winter is well upon us, which means it's the perfect time for an A/C service! Most service workshops don't include an A/C service as part of your cars annual checkup, but it's just as important and can save you hundreds (sometimes thousands) of dollars later on. While automotive A/C systems are fully sealed, refrigerant gas slowly escapes over time through natural permeation via rubber hoses and seals (up to 15g per year). If refrigerant levels fall low enough your system can easily overheat, leading to a lengthy and costly repair. Having your A/C serviced annually will ensure all the components which make up your system are working efficiently and your refrigerant remains at manufacturer specified levels.

What we're about to say might sound silly, but it could also save you some $$! If you've noticed your A/C isn't cooling, check that you haven't accidentally pushed these buttons before booking in for a quote. If your A/C button is off or your eco button is on, you'll only be getting ambient air through your vents - which isn't what you're after in the heat of summer!

It sounds obvious, but believe us, it does happen. Have a look and you might save yourself the time of taking your car to a professional, and some $$ on having them push a button.
