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!

Car Air Conditioning Repair

Even though it has only been a few weeks since Punxsutawney Phil saw his shadow and so determined that we would have six more weeks of winter. This is the perfect time to bring your car in and have the air conditioning serviced or repaired. If you bring it in now it will save you the worry of whether or not the air conditioning will work when the weather gets warmer.  And it’s also a good idea to have your car air conditioning system checked out once a year just so you can avoid major or costly repairs.

We don’t “top off”  your air conditioning system when you bring in your vehicle because your technician has no way of knowing exactly how much Freon is left in your car’s system.  If he tops off the system, he is relying only on his experience to guess how much Freon is needed to charge the system, which may or may not be correct.  So in order to do what is best for your vehicle we will perform an evacuation and recharge service.   During an evacuation and recharge,  all the remaining Freon is extracted from the system, so then the technician can charge the system with the exact amount of Freon recommended by the vehicle’s manufacturer, then there is no guess work involved.  Another reason some technicians recommend an evacuation and recharge is because they believe it is better for the air conditioning system to have clean Freon running through it.

As well as checking the Freon level, your hoses and valves need to be checked to make sure there aren’t any leaks.  Even the smallest leak can cause a major problem.  So don’t wait around until you can’t live without your air conditioning before you get it in for repair!

Radiator Flush

During the winter months when the temperatures can be as cold as below zero and in the summer when the temperatures can be so hot you’re sweltering, it is crucial your heating and cooling system is working properly.  These are the perfect times to have a radiator flush performed on your vehicle.            

The engines in today’s vehicles are filled with parts that are made of aluminum.  Water pumps, manifolds, engine blocks and the heater and radiator are all made of aluminum.  In order to protect the aluminum in these essential parts from corrosion, you need fresh anti-freeze in your engine.  Your anti-freeze should be checked during routine maintenance visits but you should also have a radiator flush done at least once a year, maybe twice a year, depending on the vehicle you drive and how it’s driven.

Every time you drive, your radiator is using up a coolant (anti-freeze) and water mixture to help bring down the temperatures in your car’s engine system.  The longer and the faster your car is driven the more stress is put on the engine, causing temperatures to soar.  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 other fluids used in your vehicle, will break down over time.  This is why it is important to replace or flush your coolant mixture.  When the coolant breaks down more stress is placed on your radiator and your engine runs 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 necessary steps to get one and maybe save yourself some headaches in the future.

Cabin Air Filter

by Leave a Comment

Now that the weather has gotten colder and we can no longer drive around town with our windows down.  Have you noticed the air blowing around inside your car isn’t as quite as fresh smelling as it once was?  If that is the case, it might be time to change your cabin air filter.  The cabin air filter is an essential part of your car’s ventilation system.  It removes dust particles, pollutants, and unpleasant odors from the air before they can enter the passenger compartment. Cabin air filters are also called interior ventilation filters, pollen or dust filters, ACC filters, or passenger compartment filters.

A cabin air filter purifies the air ( which is especially important to those of us who suffer with allergies or respiratory problems).  And it also protects the heater and air conditioning components.  A dirty filter puts more wear on the ventilation system because when there is a higher resistance to air flow, the blower has to work much harder.  This reduces your heating and air conditioning performance over time.  So if your filter isn’t changed like it should be, you not only have unpleasant odors to deal with, but possible repairs to the ventilation system.

So when should they be changed?  Under “normal” driving conditions for a vehicle driven mainly in a city or suburb area, a cabin air filter lasts about a year.  For a vehicle in a rural area that is driven frequently on unpaved roads, the filter life may be only six months or less.  A lot depends on the vehicle and the way it is driven.

If you aren’t sure whether or not you have a cabin air filter in your vehicle, more than eighty percent of all new vehicles today have a cabin air filter.  If your car was manufactured after 2000, than it more than likely has one. But if you’re driving an older model of car and smell a strange odor, unfortunately, it might not have a thing to do with a cabin air filter!
