Does my car A/C need Freon?

Does my car A/C need Freon?

Many people ask if their car’s A/C needs more Freon to help it cool better. Freon is a brand name for A/C refrigerant (the Kleenex of refrigerant). Having a low level of refrigerant can be a reason for an underperforming A/C, but it is also a symptom of a problem.      Here are 3 signs that your vehicle may need refrigerant: 1) If you notice that your A/C isn't blowing as cool as it used to, that could be a sign that your refrigerant is low and needs to be re-charged. Low refrigerant levels cause your vehicle's A/C components to not work as effectively as they are designed. 2) If you notice a hiss or high-pitched hum noise from under the dash, it is possible that the A/C has low refrigerant. When there is not enough refrigerant in the system some vehicles will make an audible noise under the dash. This noise is from a low level of refrigerant rushing through the vehicle's expansion valve. 3) If you can see vi ... read more

Is my car A/C compressor bad?

Is my car A/C compressor bad?

The compressor is an essential part of your vehicle’s A/C system. It has the job of turning your refrigerant from a low-pressure gas into a high-pressure liquid. Without a functioning compressor, your A/C system will not work properly. Here are Some Signs of a Bad A/C Compressor: 1) Lack of Performance from Your A/C System If you notice your A/C is not cooling the way it used to, it is possible that your compressor has either electrically failed or is internally worn. 2) A Sharp Tapping Noise Under Your Hood when the A/C is On If your vehicle makes a fast sharp tapping noise, only when your A/C is on, it is possible that your A/C compressor has failed. It may have some metal-on-metal contact internally. 3) A Burning Smell from Under Your Hood when the A/C is On If you notice a burning smell from under the hood of your vehicle only when your A/C is on, it is possible that the compressor clutch has failed. It may not be able to en ... read more

Why is my car A/C not blowing cold air?

Why is my car A/C not blowing cold air?

After months of cooler weather it can be a surprise, on that first warm day, when you realize your car A/C isn't blowing cold. What happened?! What causes your A/C to blow hot air? It could be many things – the refrigerant level, a fan failure, a compressor issue, or a variety of other concerns. If any part of the system is not working properly, your A/C will not function to its potential, leaving you hot in your vehicle. At Tim’s, we start with our A/C Performance Check. It is an all-inclusive service that we offer to determine the source of the problem. Here is what we do: We evacuate the refrigerant out of your vehicle in order to see how low the charge was. We then hold the system under a deep vacuum to test for any large leaks. After that we allow the system to sit under vacuum to check for smaller leaks. We also use UV dye so that we can use a black light check for very small leaks. We then charge your A/C system by weigh ... read more

When do I need to change my cabin air filter?

When do I need to change my cabin air filter?

   Your Cabin Air Filter helps improve the air quality inside of your vehicle.  It also protects parts in your a/c system from becoming clogged or coated in dirt and dust. But when do you need to change your cabin air filter? Cabin air filters become restricted or clogged once they have become full of particles.   How often your filter needs to be changed depends on the conditions your vehicle encounters: • Vehicles that are driven off-road or on construction sites are exposed to lots of dust and debris • If you park under or near a tree we also find that leaves and pollen make their way into the cabin filter • If you regularly transport pets you will also find that your Cabin Air Filter will become full of pet fur All of those conditions may cause your Cabin Air Filter to need changing more frequently.  The mechanics at Tim’s will check the condition of your Cabin Air Filter at every service. If your filter is clean ... read more

When do I need to change my Engine Air Filter?

When do I need to change my Engine Air Filter?

Engine Air Filters help protect your vehicle. It filters contaminants in the air that can clog and damage your vehicle's A/C system and internal engine components.  All Engine Air Filters wear out in the same way. They get clogged and restricted after they become full of particles that they removed from the air. But when do you need to change them? The answer is… it depends. Depending on the conditions the vehicle is being operated in, as well as where the vehicle is parked.  If you drive off-road or through construction sites, you may need your filter replaced almost every time you get an oil change. Also if you park your vehicle near or under trees, your cabin air filter may become restricted much sooner. Vehicles that are parked in garages or far from trees, and drive in less dusty conditions will see much longer life from their filters.  At Tim’s, we check your Engine Air Filter at every service. We take pictures, give ratings, and will let yo ... read more
