Your Thermostat Should Have Settings Of FAN- auto-off-on. If It Is This Way Set It To Auto, If Not Set It To On, It Should NOT Run All The Time Only When There Is A Demand Signal. Then Shut Off Until A/C Kicks On. If Your Condensor Unit ( Outside ) Is Running The Fan Should Be Also. When The Condensor(compressor ) Outside Unit Is Off Your Fan Should Be Also. If This Does`nt Help, Read Your Installation Instructions Over. If This Thermostat Is Not A New Installition. It Should Work As Above. HOPE THIS WILL HELP It doesn't matter, as far as the operation of the system is concerned. Some leave the fan switch "on", which means the blower will run constantly, believing this will provide a more uniform temperature throughout your home (and it really doesn't cost that much to operate the blower all the time). Others see no difference. I suggest you try it both ways, several days each way.

Sounds like the thermostat is set too high so the unit is calling for heat... If the thermostat is set normally then the unit has a fault. Repairing an air conditioning unit is not a Do-It-Yourself job. The best advice anyone should give you is to call a licensed Heating Ventilation and Air Conditioning (HVAC) technician to check the unit for you. If it is faulty it can then be decided if it is worth spending money to repair it or if it makes more sense to replace it with a new one.

Air conditioning is important for almost all areas of the world that have a warm season. Unfortunately, it can also drive up energy costs. It can also be tricky to know how to set up your air conditioning when it's first being installed, no matter if you have a window unit or central air conditioning. Then once it's set up, you'll need to figure out how to adjust the thermostat for your best comfort level. Here let's take a look at how to make the most of your air conditioning in these three areas. It's a simple fact of life that air conditioning can drive up your energy costs. However, there are a number of simple things you can do to lower both the up-front costs and the reoccurring costs from your energy bill. When you're buying air conditioning units, you should always try to get units that have an EnergyStar certification, or its equal. These units often cost a little more up-front, but have lower reoccurring costs because they use less power to operate. To offset the higher up-front costs, you should try to purchase your air conditioning units in the off season when they aren't in such high demand, and stores are trying to quickly sell the remaining units they have in stock. Air conditioning units are rated for square footage, no matter if you have a window unit or central air conditioning. When placing window units, they should be placed as low as possible in the window for maximum efficiency in terms of square footage. With central air, if you're putting in vents, you should make sure there is one in each major living area and bathroom. However, you should keep them out of the common walking area if at all possible since they can crack and cause leaks. Conventional wisdom suggests that people are the most comfortable around 72 degrees Fahrenheit. However, everyone is different, and not everyone feels comfortable at the same temperature. If you move the thermostat up a few degrees, and wear lighter clothing to compensate, you can keep about the same level of comfort while lowering your air conditioning costs. Once you get used to this level of comfort, you might wonder why you ever kept the thermostat lower at all.

Purchasing a new central air conditioning unit will save you money on your electric bill. An old out of date unit might not be cooling the house suitably. Units that are more than ten years are usually not energy efficient and should be replaced. The outlays for a new unit might be costly, but will more than pay for itself by lowering your electric bills. To prevent future problems with your new central air conditioning unit, be certain to have your system maintained according to the warranty agreement. Contact a reliable air conditioning company in your area, and sign a contract for a once a year inspection of your air conditioning unit. How You Can Do Your Part in Maintaining the Unit and Keep It Running Cool? 1. Make sure that the central air conditioning unit is inspected before the temperature gets hot. Service contractors are normally tied up when temperatures rise by repairing air conditioning units that are not functioning at all. 2. Keep an eye on your room thermostat settings. The room temperature in the residence should read the same as what it was set at. If the thermostat is not working properly, and the house is extremely hot, contact your air conditioning contractor, and schedule a service call. 3. Inspect, change or clean the central air-conditioning filter once a month. If there are pets living in house, the filters might have to be changed more often. A clogged or filthy filter will cause the unit to work twice as hard to keep the home cool. How To Make Sure That The Air Conditioner Is Properly Servicing The Unit? 1. Watch to be sure that he is checking all of the connections inside of the central air conditioning unit. 2. Make certain that the contents inside the unit are being lubricated and do not make any noise. 3. Notice if he is checking for clogged drains. Drains that are clogged usually do not permit the water to flow freely to exterior of the air conditioning unit. 4. Be certain that he shuts down the system in the house completely and starts it up once again. This makes sure that the central air conditioner is cooling the house at your set temperature level. Generally, the air maintenance serviceman will clean the inner parts of the central air conditioner. This includes the coils. Additionally, he will add the proper amount of refrigerant if the level is low.

Any electrician in your local directory or good diy enthusiast should be able to replace any thermostat in your home, be it part of a central heating system or household appliance.

Central air conditioning may not always be the most practical choice for every home or office. There are some cases, however, when using a central air conditioner is vital to the health of everyone who lives or works in a home or building. The Length of the Hottest Season The biggest consideration for whether or not central air conditioning is the best answer is how long the hot season is in your location. Some areas have a very short hot season that only lasts a couple of weeks. The expense of installing and maintaining central air conditioning may not be worth it if you only use the system once or twice a year. If your hot season lasts for months, though, the use of central air conditioning may feel like more of a necessity than a convenience. The Size of the Building Building size also makes a difference when you consider central air conditioning. If your home or office is relatively small, you may be able to make due with a window air conditioner or a portable air conditioner. If there are more than four or five rooms, central air conditioning may be the best answer. With a central air system you can be sure that every room is cooled equally. When you use other air conditioning systems, their cooling effects can only be felt in the room that they are housed in. If you have a building with a large central room, portable or window air conditioners may not have the power to fill the space the way that central air conditioning could. The Health of the Occupants Central air conditioning is the best type to use if you are trying to keep older or younger people comfortable through the heat of the summer. Any building that houses senior citizens or young children should consider the benefits of central air conditioning to keep their inhabitants safe from the damaging effects of heat. People who are old, young, or in ill health are particularly susceptible to heat. Portable and window air conditioners may work for the short term, but central air conditioning will provide a more even distribution of the cool air.

You should use a thermostat gasket along with the thermostat housing ring. The gasket should be replaced every time the thermostat housing is opened.

Yearly or bi-yearly check ups and filter changes are the principle expenses. As long as you maintain the unit you should be able to avoid expensive repairs.

You might want to repost your question to be more specific. Are you talking about the air conditioning thermostat inside the car? If so you should invest in a maintenance manual (Chiltons, Haynes or Toyota Factory) to make the job much simpler. If you're talking about the engine thermostat the generic answer is: The thermostat is mounted in a housing behind the top radiator hose. How you get to it depends on the engine, 4 or 6 cylinder. Again, a manual might be helpful. Cheers

I would call someone who is used to dealing with thermostats and repairs to come look at it before you buy a new one. They should be able to tell you if it's fixable and how much it would cost to fix.

If it's an older mechanical thermostat, no, you're not using ANY energy if the AC compressor and fan are not on. The newer, electronic thermostats use such an incredibly small amout of energy that it's not worth mentioning, but you also can't say it isn't using ANY.

First locate the top radiator hose,that hose should lead you to the thermostat housing. Second you loosen that hose from the thermostat housing. Third you take of the 2 Bolts off from the thermostat housing, they should be a 13mm or 1/2 inch socket or wrench and when it's off you should see the thermostat.
