I hate when my car windows fog up. Is there a trick to defogging them as quickly as possible? Dear Can't See the Street,Depending on the temperature and the situation you'll want to attack the condensation on your windows with different methods.It's chilly in most of the US right now, so we'll assume you're worried about the interior of the window fogging up. The fogging occurs because of the temperature and moisture differential between the inside of the car and the outside of the car. Outside it's cold and dry—it might not seem dry with all the snow and slush but winter air has very low humidity—and inside it's warmer and moister thanks to your body heat and the moisture from your breath being trapped inside. In an emergency, when you need the window defogged right now, the fastest way to do so is to rapidly lower the inside temperature so that the moisture stops condensing on the glass. Turning the defrost vent on without heat or opening the windows is the fastest way to dissipate the fog on the window.

While fast, it isn't very comfortable for the occupants of the car so it's best reserved for times where you find the window suddenly fogging up and you need to see out in a hurry.It's significantly more comfortable to use your heater and employ other tricks to manage the moisture than it is to keep your car freezing cold. Warming the inside of the car and blowing warm air across the windshield using the defrost setting will evaporate the moisture. Skip using the recirculate feature if your car has it, you want to push the humid air out of the car and bring dry air in from the outside. You might be conditioned to use the recirculate feature to make the most of your AC in the summer but in the winter it doesn't matter—your engine has more than enough excess heat to go around. While we're on the topic of summer time, in particularly humid weather you have to deal with the opposite problem. High humidity and temperature on the outside of the car and low humidity and temperature on the inside of the car—thanks to the AC!—make it necessary to reverse your technique.

You can use your wipers to constantly clean away the fog from the exterior but that's a bit of a hassle. You can turn the AC down or off entirely, or you can turn the heat on low and warm the inside of the glass to stop the moisture from condensing on the outside. ac unit prices for homeYou won't often encounter the fog-on-the-outside situation, compared to the winter effect of fog-on-the-inside, but when you do it can be a real pain.does ac unit workOur final tip: keep your windows extra clean. why would ac unit not turn onNot only do clean windows help with visibility even when you're not dealing with fog, clean windows are less prone to fogging.Keeping it Between the Navigational Beacons,As summer is approaching we should consider our car’s air conditioner.

It is so important that it is in good condition for the heat of an Aussie summer, not only for your comfort but also for your health. Today we’re also going to have a look at what consists in a good air conditioning service. A regular car air conditioner service or regas will help to ensure optimum passenger comfort, particularly on those hot summer days when you need it the most. Contrary to what some people believe, an auto air-conditioner system does not simply blow cold air into the car. The Air-con system is actually designed to remove the hot air from within the vehicle cabin and dispel it to atmosphere outside the car. In order to do so, the airconditioner system relies on a number of components to operate effectively, such as the evaporator, condenser and compressor. Like all mechanical parts, these items are prone to wear and regular system servicing helps to protect them from breakdown. To help maintain the car airconditioner system it pays to run the system for a few minutes at least once a week – no matter how hot the temperature may be.

This ensures that the many hoses, valves and pumps throughout the system are kept well lubricated. Whenever you have the car serviced, make sure you ask the mechanic to check the refrigerant level and regas the system if necessary. The Air conditioner is not always included in a standard log book service, so it can be easily neglected. It is good practice to get a full air conditioning service at least once a year. Try and do this before the hotter months start, as this will ensure that you are not caught out by a sudden heat wave at the start of the season. A car air-conditioning system can be a breeding ground for harmful bacteria and fungus. This is particularly important for sufferers of asthma or allergies. Your local Repco Authorised Car Service mechanic can provide you with information on special sanitizing treatments that can help to remove these contaminants. These treatments are designed to protect you and your passengers and also help to remove the musty odour that can be evident from the air conditioner vents.

Just as the climate in Brisbane or Perth may be vastly different to that of Melbourne or Hobart, they way an air conditioner is serviced can also vary. In most states, a mechanic must be licensed or specially trained to carry out an aircon re-gas or service. Repco Authorised Service workshops operate in different states and therefore under different legislation for repair methods and mechanic licensing. This means that an air conditioner re-gas in Adelaide may different to a re-gas in Sydney. Added to this, different cars may also have specific service requirements that are unique to the make of car or the particular model. Your local Repco Authorised Car Service mechanic will happily explain what is involved for your particular car. Common Items that may be involved in a car air conditioner service or regas; Refrigerant gas is extremely damaging to the ozone layer and any gas that is irresponsibly released into the atmosphere by repair shops, garages or backyard mechanics can harm the environment and contribute to global warming.
