Eight service reasons your car may not be cooling fast enough
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
If your car’s A/C system is not cooling you off in a reasonable time frame to make you happy, take it to your service professional for an A/C check-up. Here’s what he or she will look at:
• Is the compressor weak? It may build up pressure slowly, or require high rpm to produce normal pressures, so it takes a while to produce adequate cooling. A pressure test should indicate this problem.
• Outside air flap not closing. When the system is in Max A/C, the flap should be closed. Unless the flap is closed, hot outside air dilutes the effect of A/C, producing slow cool down.
Two tips to a cooler cabin
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
No one is particularly patient when it comes to passenger compartment cool down in hot weather. We’re all impatient in today’s society. We want it now! So, when the inside of our car is hot we are also cranky. You know how it goes, you start the engine, hit Max A/C and turn the blower up to High expecting to get hit with a blast of icy-cold air. Lots of luck! In most cases, the blast will be something out of a Sahara storm, and it will continue until all the hot air is blown out of the HVAC case.
Cabin Air Filters, a breath of fresh air

Check your owner’s manual to see if your car has a cabin air filter.
If the answer is yes you may want to make a note to check with your service professional to see if it should be replaced. This is especially true if you suffer from asthma, allergies or live in a dry and dusty environment.
There are two basic types of cabin air filters
1. The more popular particulate type, which is designed to remove particles above a
certain size.
2. The dual-function which has an activated charcoal layer on one side to trap odors.
Causes and Cures of A/C Odor
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
Air conditioner odor complaints are a common consumer problem. Why?
A/C system odors typically result from uncontrolled growth of bacteria and other microorganisms in the evaporator part. Nasty little beasts like aspergillus, cladesporium and penicillium grow on cooling coils and other areas. How do these beasts get there?
They are naturally present in outdoor air and are drawn into the system through the evaporator during system operation.
Five Cool Tips For Staying Cool on the Road
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
Temperatures over 90 degrees and high humidity can challenge your vehicle’s air conditioning system. Here are some easy tips to keep you and your passengers cool on the road.
• If possible, leave the windows down slightly on hot days to reduce heat build-up. An A/C system works by removing heat, so the cooler the interior is to start with, the easier and faster the A/C will do its job.
• When you get in the car, open all the windows completely, or even open the doors, for a moment to vent the hot interior air quickly.
Your Car’s A/C System and the Environment
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
Few motorists know that the air conditioner in their vehicle has been a focus of worldwide environmental concerns and international efforts to address those concerns for several decades, or that they can play a major role in protecting the environment through their choices.
The same refrigerant, CFC-12 or R-12, was used in mobile air conditioning for more than 50 years, through the mid-‘90s. Inexpensive and thought to be environmentally benign, R-12 refrigerant was routinely released to the atmosphere through leaking systems or simply vented prior to system service and repair.
It's Hot! Know Your A/C system to stay cool
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
When your car’s air conditioning fails, it can be more than a nuisance—it can become a health and safety matter.
Most of us first notice an air conditioning problem when the car gets hot and muggy. But those with allergies can be quickly exposed to irritants when the windows are rolled down. A cool passenger cabin has also been cited as a factor in keeping the driver alert.

The Motorist’s Super 7 Air Conditioning Checklist
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
Hours spent in a hot, stifling vehicle can spoil a weekend getaway or vacation. Conducting a periodic under-hood inspection may help you spot air conditioning problems before they spoil your trip.
Here’s what to look for:
Note: Always be extremely careful any time you’re under the hood while the engine is running. Stay away from all rotating components with your hands, clothing, and hair, and always wear eye protection around a running engine.
1. Are A/C component mounting bolts in place and tightly secured?
The Green Facts About Your Car’s Air Conditioning System
Brought to you by Mobile Air Conditioning Society Worldwide (MACS)
Your car’s air conditioning system uses a chemical refrigerant under pressure to make the interior cool. MACS Worldwide wants you to know about the environmental damage chemical refrigerants can create when the system is not serviced properly. Proper handling of these chemicals can help the environment and save you money.
