Should your programmed thermostat be used with the fan switch set to on or off when using central air conditioning?

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.

What should be the difference between inside and outside air be when the thermostat is set at 68 with referigated air-conditioning in the home?
Depends on the outdoor temp. If it's 75 outside, your system should easily bring your house down to the 68 degree setpoint. If it's 100 degrees outside, you'll never get there. Unless, that is, your system is too big for your home. Then it will cool you down just fine, but you'll have humidity problems...that's a whole other discussion. Most central air conditioning units are designed to maintain a 75 degree indoor temp at 55% relative humidity on a 95 degree day. So a indoor/outdoor temperature difference of about 20 degrees or so is what you should expect.
How does a 240 volt hot water heater thermostat test for normal operation?
As with any thermostat it is based on where the set point is on the temperature scale. On hot water tanks the thermostat opens the element circuit when the set point temperature is reached. For example the set point should be around 135 degrees F. When cold water enters the tank, the thermostat closes due to sensing a temperature lower than the set point is set at. When the water heats up to 135 degrees the thermostat open because the set point is reached.To test the thermostat shut the power off at the distribution panel for the hot water tank. To do this test the water in the tank should be up to temperature. Remove the wires from the thermostat that is to be tested. Make a diagram of how the wires were connected. Using a continuity tester (ohm meter works fine) place the leads across the terminals where the wires were connected. If there is no reading then the set point is satisfied and the circuit is open. Leaving the tester leads on the terminals, with a screw driver raise the set point to a higher value. The meter should now show continuity between the terminals. Turn the set point down and the terminal reading should open. If this is happening then that thermostat is operating fine. Reposition the thermostat to the original set point. If you are working on the top thermostat now do the same to the bottom thermostat to see if it is working also.See related link below.
Why would our Central Air Conditioner Freeze up We then turn it off for a period and it works fine again for a few days?
Sounds like you are low on refrigerant. Fixing ac units is not a DIY job so the best advice anyone should give you is to call a licensed HVAC (Heating Ventilation and Air Conditioning) technician to advise you further.
How long should a furnace run during a typical heating cycle?
I just installed a propane furnace, I don't know what kind you have, but mine runs about 9 minutes. Depending on the draft or air movement around the thermostat and coolness a furnace should cycle on average, so I'm told, 3x's an hour. If you ask me that would mean some major air issues, but I'm not the furnace expert. Anyways hopes this helps. Best thing to do is call a heating-air conditioning person.
How cold on average should a central air conditioner blow?
straight from the vent should be around 47 degrees
Should cold air vents be closed when using central air conditioning?
no
Does central air conditioning put out the same amount of cool air despite what is entered on the thermostat For example 65F always comes out of vents even if thermostat is set to 58F.?
you could put the thermostat at 65..if the unit calls for ac it will start and depending on the temp of the air returned your supply air should generally be 14-15 degrees cooler. The numbers will improve as the system runs...the system will run until the thermostat is satisfied.....so to answer the question ..no.....
If you have central air conditioning should you close the vents in unused rooms?
yes it would save money :)
What amperage service is needed for central air conditioning unit?
30 to 50 amps, it should be dedicated for the A/C.
Should I install a central heat and air conditioning unit?
To cool more than two rooms it is economically more efficient to purchase a central air conditioning unit than a wall unit. Wall units are individually cheaper than central air, but if you have to buy more than two, then it is better to buy the central air unit.
In a central heating unit why does heating element keep coming on when the heater is not on?
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.
What should the temperature of the coolant return line on a central air conditioning system be?
It should be above freezing. Normally around 40-42 deg. F
Why does the Toyota Celica overheat when you use the air conditioning?
Under normal conditions a modern vehicle should not overheat when the air conditioning system is on. The first steps to investigating this condition are ensuring correct coolant level, condition, flow and thermostat actuation.
Should you turn off central heat and air while heating with wood burning stove?
Yes- or turn the thermostat back.
Making the Most of Your Air Conditioning?
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.
Who should you contact to put freon on your central air conditioning unit?
A reputable HVAC service Co. will locate and repair the leak and recharge your system.
Use adjust in a sentence?
One uses the thermostat to ADJUST the temprature of your central heating. you should adjust your head and make sure its on properly
