Let’s talk about AC repair and service. Most of us don’t give our air conditioning a second thought as long as it’s making cold air. But it’s a complex and expensive system that we should think about before it starts blowing hot air.

The refrigerant in the air conditioner contains a special oil that lubricates and cools the A/C parts. When enough refrigerant leaks out, your air conditioner still makes cold air, but the parts don’t have enough oil to protect them and they wear out faster than they should so it’s important to service the air conditioner as recommended.

Replacing old refrigerant has another benefit: refrigerant tends to gather moisture and become corrosive. That causes leaks in the system which can be expensive to repair. Fresh refrigerant protects the air conditioning components and keeps the system operating at peak efficiency so it doesn’t have to work as hard to keep you cool.

AC Refrigerant System Recharge

Refrigerant is responsible for cooling the air inside your vehicle. If there is no refrigerant, there is no cold air. To explain, air will still blow out, it just wont be cold. If you’re experiencing warm forced air through your vents, it could be because of low refrigerant or even a leak.

Our recharge service is simple. Firstly, we drain the system of all existing coolant. Secondly, we recharge the air conditioning system with fresh refrigerant. Lastly, we inspect the temperature control and pressure systems to make sure all the parts are working as they should.

We also determine if there is a leak anywhere within the system. At this instant, we will explain what a proper fix will entail and outline next steps to you.

Even with regular service A/C parts can just wear out. Normal wear and tear eventually gets to all moving parts. Addressing early problems can save on more extensive repairs down the road. For instance, a common failure is the clutch that turns the compressor on and off. If you can take care of a bad A/C clutch when it first starts having problems, you may be able to save the compressor. Wait too long and you’ll have to replace both.

Check your owner’s manual or ask your service advisor for service recommendations. And if you’re hearing strange sounds when your air conditioning turns on, or if it just isn’t as cold as it used to be, have us give it the once over see what it’ll take to keep you cool.

Why Isn't My Air Conditioner Blowing Cold Air?

Your air conditioning system uses refrigerant to create cold air. The most common reasons why your vehicle’s air conditioning system would lose their cold air will have to do with the refrigerant. The first main issue is generally not enough refrigerant. Refrigerant is a gas in the...
