Does the furnace blower come on? If it does there is something wrong with the outdoor unit. Go outside and see if the unit outside is not running check to make sure the breaker is on and there is power to the outdoor unit. If there is power at the outdoor unit, the capacitor may be bad. Disconnect the power to the outdoor unit and open the electrical panel. there is a round or oval silver cylinder inside. If it is bulged at the top where the wires are connected, that is a true sign of failure. Take it out and take it to your local HVAC wholsaler or contractor and have it replaced. It should be around 30 dollars for it and its a simple and very common problem. If this does not fix it, I would call your local NATE certified technician to come take a look at it.

I don't know a good setting on a robertshaw 9420 thermostat, for really cold,and fast air condition.


Well Brian, an air conditioner creates the same temperature drop across the evaporator at any thermostat setpoint, so there is no setting that will get it really cold really fast. If your return air is 88 degrees (in a hot house where the system has been off) the supply air temp is going to be near 68 degrees..... as the a/c runs, the air changes within the structure cause a reduction in the average return air temperature and slowly drops the return to 87, then 86 then 85 etc, etc and the corresponding supply air temp continues to drop from 68 to 67 to 66 to 65 etc etc. Eventually the supply air temp after the appropriate 'air changes' within the structure will drop to 55 degrees and possibly even lower to satisfy the average room temp at 75, 74, 73 etc. to a point.

There are SOME newer a/cs that have two speed compressors that may effect the supply air temperature drop under differing load conditions, but thats a different ball of wax.

So, if you want it cold quickly you are out of luck, just leave the t-stat set at 70 degrees and pay the electric bill when it comes in.....

I have a Braeburn 3200 and when the the temperature reaches the desired heat setting. The furnaces heat will shut off, but the fan will continue to run indefinetly. eventually blowing very cold air up


The fan relay is stuck in the on position. When the temperature drops the heater does not ignite because the fan is already running and ignition is locked out after the heat cycle starts an the fan turns on

What does -AC on honeywell chronotherm III thermostat mean?


AC means "air conditioning." If the AC icon is showing on your thermostat it means that your air conditioning is activated and should come on when the temperature threshold you've set on the thermostat is reached.

For example, if you've set the temperature level to 78 degrees, when the house temperature goes above 78, usually by about two degrees, the air conditioner should cycle on to cool it back down to 78 degrees at which point it will then turn off.


This information should be in your air conditioning/heating system or thermostat owners manual. If you don't have the manual, you should contact your air conditioning dealer or your builder to secure a replacement. The manual is essential for proper operation and maintenance of your system.

I have a Honeywell programmable Thermostat (an expensive one that handles humidity, etc) and every spring and fall the thermostats behave improperly by ignoring the programmed temperature and cooling the...


What is the model number of the thermostat? What may be happening is the humidity control is trying to satisfy the humidity setting by running the a/c. In the installers set-up, there should be a setting to determine how long the system should run to satisfy humidity setting. I typically set thermostats for a 3 degree droop. Meaning it'll only drop 3 degrees below set temp. Also check your humidity setting to be sure it's not set too low. It should be set between 45% and 50%.

AC Thermostat is set to 78 but wont cool past 79 or 80


If your unit is running 24/7 you are either low on charge or the unit is to small for your house.
A 20° temperature difference is about normal for the room air vs the air coming out of the ducts, but the room air and the leaving air should keep getting colder and colder.
An air conditioner should cycle approximately 3 maybe 4 times in an hour if it's properly sized.
As for the thermostat thermometer they are very cheap and are more for reference than actual temperature, so if 78° is not comfortable, then you should set it lower but not rely on thermostat being accurate or what the thermometer is saying as long as it is consistent.
The air conditioner and thermostat can also be set below 78°, there's a lot of people set them at 72° and below with no problems.
the only thing is if you have real low humidity you'll need to watch indoor coil or the suction line (the big line) on your outdoor unit and make sure it doesn't freeze up on you.

How do i set my temperture on my air conditioner its stays at 78 and doesnt seem cool in my house


sounds like you could be low on charge,If you set you thermostat @ 78 degrees it should stay within 2 degrees of that and not have more then a 6-8 min cycle every 20 min.

My central ac system occasionally runs too long and the temperature gets way too cold. The digital thermostat reads that the temperature is too high so the ac still runs. This doesn't happen all the time...


I have seen this is many digital thermostats. The worst problems usually come from the touchscreen thermostats. I would suggest installing a new thermostat. Make sure that you read the instructions before you even remove the old one.
