No matter where you live, you want your vehicle's air-conditioning unit to work properly. That is especially true here in the Lone Star State. I don't have to tell you it can get pretty hot and muggy here in Sherman, Texas. There's a good chance you'll see more than a few 100 degree days in the summer months.
And from April to October, 90 degrees and higher is common. Factor in a sweltering humidity in the summer, and you understand why Sherman has a heating cost index 42% higher than the rest of Texas (data from USA.com National Heating Index). What this all means is that your vehicle's air conditioner had better be in apple pie order or you are going to feel like you are driving around in an oven.
When it comes to automobile air conditioner repairs, proper maintenance can save you a bundle of money. That means getting an A/C checkup regularly, especially if you're going to be taking a long summer trip. Let's look at a few common auto A/C problems, as well as some advice to keep you cool when the Sherman, Texas weather heats up.
Common Automobile Air Conditioning Problems
Your car's air conditioning unit doesn't blow cold air - This could mean that you are low on refrigerant. This could be due to a leak, or you may just need to be topped off.
Little or no air comes out of your vents – Your fan's blower motor might be blown. You can also be experiencing a resistor or switch that isn't working.
Your air-conditioner only runs at one speed – You could have a blown switch. More likely, a blower motor resistor that controls the voltage going to your blower has died.
Sometimes your A/C works fine, and sometimes it doesn't – This is many times due to a short or some other type of electrical problem.
When you run the air it makes funny noises – A faulty compressor lets you know it is about to kick the bucket by making unusual noises.
Some common automobile air conditioning problems can be simple to fix. It may just take replacing a hose or an inexpensive sensor. Depending on the make and model of your vehicle, labor could be minimal, or intensive. For instance, air-conditioning evaporators are usually located behind the dashboard. So labor for that type of job would be higher than if a hose simply needs to be replaced.
How Do I Know If It's Time to Replace the A/C Compressor?
When your car's air-conditioning compressor goes, your days of feeling cool in the oppressive Sherman, Texas heat are over. But how do you know when it's time to replace your compressor? Wouldn't you rather replace it before it dies, so you don't have to experience any suffering, sweaty heat in your vehicle?
As we just mentioned, sometimes your compressor will begin making funny noises. It is telling you that it is almost at the end of its road. Most of the time a car air conditioner compressor is driven by a serpentine belt. It may start to squeal before it breaks, but it also may pop with no warning.
The only way to know if it is time to replace your compressor is to have your air-conditioning unit checked. Think about the last time you were driving around in the heat, in a car with no air conditioning. It wasn't too much fun, was it? We can give your entire air-conditioning unit at check, and let you know if there's a problem on the horizon.
What About My Car's Heater?
Don't forget, heating is a part of climate control too. Just as you hate to be dripping from head to toe in the summer, it's no fun to be freezing your rear end off in the winter when you are driving.
If your heater core is clogged with sediment (which naturally builds up over time), it needs to be cleaned or replaced. This happens to a greater degree when there are longer periods of time between coolant flushes. You may also get corrosion from a leak, or moisture that accumulates.
This means that first cold day of winter when you step into your car and turn on your heater, you will be waiting forever for your vehicle's interior to warm up. A lack of hot air could also be caused by a bad thermostat. If the thermostat in your engine's cooling system prevents warm coolant from circulating through your heater core, you will get no warm air blowing from your vents.
Obviously, if your blower motor is going, this affects both your heating and cooling experiences in your vehicle. For your vehicle's heating and cooling needs, we will be glad to give you a checkup and make sure your air-conditioning system is working properly.
