Your mechanic may bring up recharging your AC with you if they notice your AC isn’t cooling your car properly. Your car may need that AC recharge if it is low on refrigerant, used by air conditioners to maintain cooling and pressure. A fresh batch of refrigerant, or Freon if your car needs it, will help your air conditioning system keep cool. When you get your AC recharged your auto repairer will fill up your air conditioning system with a fresh batch of refrigerant to go along with any repairs your AC may have needed, and test your system to ensure your AC is cooling thoroughly. Typically your car shouldn’t need an AC recharge unless you’ve had other repairs to your AC system, but your mechanic will suggest a AC recharge to you if they feel your AC could use one.
What is refrigerant?
Refrigerant is what keeps your AC cold like it should be. [...]
Your AC not blowing cold air on a sweltering day can feel unbearable. Hot air blowing through your vents could signal a minor or major issue. You could have a leak, clogged filter, cooling fan problem or some other issue. By knowing all of the reasons, you can better explain them to a mechanic or even solve them yourself.
Understand the Air Conditioning System
AC systems all run the same way, no matter the make and model of your car. Some systems may be more complex than others, but the basics are the same. The three main parts of the AC system are the compressor, condenser, and the evaporator.
\Refrigerant is the high-pressure gas that is compressed into a fluid. Your car’s condenser removes the heat from the fluid using a series of tubes. A dryer or receiver removes excess water to avoid ice forming inside the car. Refrigerants are exposed to the heat [...]
Each changing of the season creates new stressors that can affect the performance of your automobile. Having automotive problems can make you second guess taking that road trip or even a visit to the local swimming hole. What many Portland, Oregon, and Idaho, drivers do is schedule a service appointment at Mac’s Radiator & Automotive Service.
When you schedule any kind of service at Mac’s, they let you know, as a courtesy, if there are any other weak spots in your vehicle that need attention before a failure. Often times, drivers forget to change fluids, fail to top off fluids, or have premature wear in spots that they can’t see. When it comes to summertime problems, it is common for drivers to experience weak batteries, transmission problems, engine stalling, A/C system failures, and overheating.
If the air conditioner in your vehicle doesn’t keep you cool anymore, you might be in for an uncomfortable ride even on a relatively mild day. Unfortunately, the problem might not stop there. Some air conditioners can malfunction in such a way that they blow out hot air. There are a few possible solutions to this issue, and it might be a good idea to schedule an appointment with a qualified professional to get your car in working order once again.
Our guide will take you through the two most common types of problems car air conditioners exhibit, what the symptoms of these problems are, and some tips that might help you.
The Air Conditioner is Blowing Hot Air
If your air conditioner seems to be working but not blowing cold air or seems to be weak, a leak in the refrigerant, a problem with [...]
On some GM applications the high side service port is located past the condenser and before the orifice tube on the liquid line. This makes diagnosing by gauges deceiving. Usually, the high side port is found before the condenser. With the port in front of the condenser, it gives you a more accurate understanding of what the pressure truly is going into the condenser. With the high side after the condenser, you could show a pressure reading that is false, because the condenser could be partially blocked. Therefore, the only reading you are getting is what is exiting the condenser.
The correct way to diagnosis this type of system, with the service ports so close together, is through temperature testing:
Check the temperature at the inlet and outlet of the condenser. *An acceptable temperature differential is 30°-50°F .
Car giving you the summer time blues? From AC vs. rolling the windows down to keeping your pet safe, here are answers to your summer driving questions.
Like most people, chances are good that when summer time rolls around, you’re ready to get in the car and go. From a day trip to the beach to a weekend getaway, summer is all about traveling and having fun. With the snow gone and heavy spring rains in the past, you probably think nothing of getting in the car and taking off. But what you might not know is that the heat can be just as tough on your car as driving in winter.
