Air Conditioning Service

by Leave a Comment

Air Conditioning ServiceLet’s talk about air conditioning service and repair issues for the Denver CO area.  Most of us Denver drivers 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 be thinking about before it starts blowing out hot air.

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

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.

Even with regular service air conditioning 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 adviser at Express Car Care for service recommendations.  And if you’re hearing strange sounds when your air condition turns on, or if it just isn’t as cold as it used to be, have us give it the once over and see what it’ll take to keep you cool.

Did you know the Federal Environmental Protection Agency regulates the type of refrigerant you can use in your air conditioner?  Your service technicians are current on EPA rules for properly removing and disposing of used refrigerant, protecting the environment while keeping you cool.

A Long Lasting Cooling System for Denver Driving

A Long Lasting Cooling System for Denver Driving e PadsOur vehicles operate in a wide range of outside temperatures in Colorado.  That’s why vehicle manufacturers use testing grounds from the frozen tundra to the blistering desert.  Your engine coolant must be able to perform in these extreme temperatures, even if we don’t always get the extremes in Denver.

Coolant has to move heat away from the engine to prevent costly damage.  Water does a very good job of holding heat, but it freezes at thirty two degrees (Fahrenheit).  That’s why we mix anti-freeze with water – it lowers the freezing point of the coolant, and raises the boiling point as well.  A fifty/fifty blend of water and anti-freeze is the usual recommendation from Express Car Care.

And on top of that, coolant has to protect the components of the cooling system from corrosion.  Your owner’s manual will tell you what kind of coolant you should use.  Of course, your Express Car Care service representative in Denver will know what you should put in your car.

Coolant system failure is one of the most common mechanical problems people experience.  Much of that can be avoided by following factory schedule service intervals.  Check your owner’s manual or with your service adviser at Express Car Care for recommendations.  We can also conduct a cooling system inspection to look for leaks, weak hoses or bad connections.

What You Don’t Know About Your Air Conditioning System Maybe Hurting Your Car

What You Don’t Know About Your Air Conditioning System Maybe Hurting Your Car

It’s a hot day. You jump in your car, turn on the air conditioning, and sit back waiting for a cool ride. But if all of your vents never cool down and continue blowing a hot stream of air, you’ll quickly find the only thing to do is to pull into your local auto repair shop.

There are a few things you should know about your A/C system long before the heat of the summer is upon us.

  • The old standby R-12 refrigerant – trade name DuPont Freon – has been replaced by R134a.
  • Never allow anyone to mix refrigerants – the two are not interchangeable. You cannot add R134a to your older air conditioner without flushing the system first.
  • Not every auto repair shop will offer you top quality service. In order for some car repair shops to save money, they substitute a volatile mix of propane, butane and flammable hydrocarbons.
  • If your car is leaking refrigerant, you’re damaging the ozone layer.
  • Your car should undergo an annual maintenance inspection every year to check on the condition of the A/C system. It is estimated you can lose as much as 20 to 30 percent charge over a two year period, meaning your A/C unit isn’t operating at full capacity.
  • By using your air conditioning system on a hot day, it does use more gas (not by much). But the alternative may be worse. If you roll down your windows, you are actually increasing wind resistance, which can add up to 10 percent to your fuel consumption, especially the faster you go.
  • If you see a puddle of water on the ground, don’t be alarmed. This is a normal function of the air conditioning system, and will continue to drip water from the air conditioning evaporator. The evaporator has a drain tube to allow the condensation from the evaporator to drain away from the vehicle.

The only way to keep your car in top shape year round is to have your car properly maintained and repaired on a regular basis. As the Colorado heat kicks into gear, head in for a complete checkup of your A/C system, and make sure its functioning at maximum efficiency.

How Is Your Car Air Conditioner?

by Leave a Comment

What happens when you turn on the air conditioner in your car?  Do you get a nice rush of cool air?  Or if the air does come out, is it hot or foul smelling?  How is your car air conditioner working?  It can be very frustrating when you get into your car, expecting a cooling breeze, and instead you get sputters of hot air.  It doesn’t take a rocket scientist to recognize that your car air conditioner isn’t working.  With the summer months almost here, a working air conditioner in your car is practically a necessity and in this day and age, we don’t have to suffer from the heat while we travel.  The following tips should help you decide where the problem may lie and what you might do to fix it.

Your car air conditioner is made up of several parts:  a compressor, a condenser, an evaporator, and several valves, fittings and hoses.  A fairly common reason for your car’s air conditioner to stop working is a lack of refrigerant.    Pressure gauges can be used to determine if your air conditioner needs a charge, or if your system may be losing refrigerant due to a leak.  Possibly a cracked hose, a pinhole in the condenser, or a leaky compressor.  A special dye can be added to your system that will help to locate a leak.

While the car is running, turn on the air conditioner and listen for the clutch of your compressor to engage.  If it does not engage or if it engages and disengages rapidly, you could have a blown fuse or may need to replace the clutch.

If your car’s air conditioner is noisy, make sure that all mounting bolts connected to your air conditioning system are tight.  This should help eliminate any rattling or other noises.

If your system has intermittent cooling, it may be freezing up.  Air and moisture in the system can cause this to happen.  You should use a vacuum pump to rid the system of moisture and air.

If you have a mold or mildew smell when you use your air conditioner, condensation has probably become trapped within one or more of the areas of the air conditioning system.  There is a service available to remove this mold and mildew from your system.

When all else fails, take your car to your auto technician and have your cooling system serviced.  Your auto technician will be able to diagnose any problems and make the necessary repairs to make your summer driving cool, clean and comfortable.

Radiator Flushes

by Leave a Comment

During the winter months when there is a possibility the temperatures will drop below zero, and during the summer when the temperatures can be extremely hot, those are the times that radiator flushes are very important!  When you’re driving your vehicle in extreme temperatures, either hot or cold, it’s crucial that your heating and cooling system is working correctly.  Radiator flushes can help your vehicle perform to the best of its ability during extreme temperatures as well as all other times.

Today the engines in our vehicles are filled with a lot of parts that are made of aluminum.  Engine blocks, manifolds, water pumps, the heater and radiator are all made of aluminum.  In order to protect the aluminum in these fundamental parts from corrosion,  the anti-freeze in your engine needs to be fresh and clean.  Your anti-freeze should be checked during routine maintenance visits, but you should also have radiator flushes at least once a year, possibly twice a year, depending on the type of vehicle you drive and how you drive it.

Every time your car is driven, your radiator is using up a coolant (anti-freeze) and water mixture to help bring down the temperatures in your vehicles engine system.  The longer and the faster your car is driven the more stress is put on the engine, causing temperatures to go extremely high.  These high temperatures increase the potential for your vehicle to overheat.  One of the ways to avoid overheating your engine is to keep fresh coolant in the radiator.

Coolant, like the other fluids used in your vehicle, will become dirty and break down over time.  This is why radiator flushes are important, they flush and replace the old coolant mixture.  When the coolant breaks down, there is more stress placed on your radiator and your engine tends to run hotter than it should.  Dirt and deposits also build up and can reduce your vehicle’s performance.  Prolonged use of dirty coolant can result in costly damage to your radiator.  So if you haven’t had a radiator flush in the last year, take the time to get one and keep yourself and your car from overheating!

Car Heater Not Working?

by Leave a Comment

Is your car heater not working?  Now is not the time to have problems with a car heater that blows out cold air!  The temperatures are getting colder and should continue to get colder, since the winter weather has only just began.  So it is very important that we take the necessary steps to prevent our car heater from not working or have it repaired if it’s not working.

The car heater uses excess heat from the engine and transfers that heat into the passenger compartment through the heater core.   Some of the heat created by the engine escapes through exhaust, but most of the heat is circulating a mixture of water and coolant.  The coolant or anti-freeze, heats up and flows through the radiator hoses and the heater core,  as the fan blows air through the heater core.  As the air blows through the heater core, it is warmed and warms up the passenger compartment.  If your coolant is low or dirty, it makes it extremely difficult for it to flow through the heater core.  Coolant, like other fluids used in your car, breaks down over time.  So it is important to replace or flush your coolant mixture.  You should have your coolant checked during routine maintenance visits, but it’s also recommended to have a radiator flush done at least once a year.  If your coolant is dirty, it can create a blockage in the heater core.  If there is a blockage in the heater core, the car heater will not work.

If you have had your coolant checked as well as had the heater core checked to make sure it isn’t blocked, and your car heater still is not working, than it might be a more serious problem.  We don’t want anyone to have to spend too much time in a car with no heat, so come in and see us or give us a call at (303)691-2760

How To Make Sure Your Auto Air Conditioner Is In Great Shape

by Leave a Comment

Summer is here and the temperatures are rising! Nothing is quite as miserable as having to drive in the sweltering heat without an air conditioner. That is why it is so important for you to make sure your car’s air conditioner stays in top shape all summer long. Otherwise, you may be stuck in traffic one day with no air conditioning to keep you cool. The following tips will help you make sure your auto air conditioner is in great shape for the summer.

Check the temperature of the air coming out of the vents. If it is not cold, your air conditioner may be low on refrigerant. You can use pressure gauges to determine if your air conditioner needs a charge.

With the car running, turn on the air conditioner and listen for the clutch to engage. If it does not engage or if it engages and disengages rapidly, you could be low on refrigerant.

Make sure that all mounting bolts connected to your air conditioning system are tight. This will help eliminate any rattling or other noises. [Read more…]

What To Do When Your Car’s Air Conditioner Fails

by Leave a Comment

It can be quite frustrating to get into your car, ready to hit the open road, only to find out your car’s air conditioner is not working. With the summer months bearing down on us, having a working air conditioner in your car is practically a necessity. In this day and age, there is no reason why you should be miserable from the heat during your travels. So, what do you do when your car’s air conditioner fails? The following tips will help you determine where the problem may lie and what you can do to fix it.

The most common resource for your car’s air conditioner to stop working is a lack of refrigerant. Your system may be losing refrigerant due to a leak. If you suspect a leak, you need to pinpoint it. It may be a cracked hose, a pinhole in the condenser, or a leaky compressor. You can add a special dye to your system to help find the leak.

You can check the clutch of your compressor by turning your air conditioner on and seeing if the clutch engages. If it does not engage, you may have a blown fuse or the clutch may need replaced. If the clutch engages, but does not turn the compressor, you may need to replace the compressor. [Read more…]

Automotive Air Conditioning Service

What do you smell when you use the air conditioning in your car?  Do you have clean, cool air blowing into your face?  Or are you not using the air conditioner during this hot weather streak because of the foul odor that comes out when you turn it on?  If so, you may want to come in and see us for an automotive air conditioning service. 

Automotive air conditioning systems are made up of a compressor, a condenser, an evaporator,  and several valves, fittings and hoses.  If you have a mold or mildew smell when you use your air conditioner, condensation has probably become trapped within one or several of these areas and mold has begun to grow inside.

One of the key elements of the air conditioning system is the evaporator.  When the air conditioner is running, the evaporator becomes cold, but the temperature and air around the evaporator is hot, so condensation is created.  This condensation isn’t always allowed to drain properly or completely, and it begins to collect in the vents and hoses.  Mold and mildew love condensation and they will thrive in these conditions. When these conditions are present, the air that is blown out of the vents passes over the mold or mildew and you get that  foul odor. But fortunately we offer a service here at Express Care that can get rid of the mold as well as the awful smell that comes with it!  Come in and see us or give us a call at (303) 691-2760 and let us help you today!
