Everybody likes being comfortable, but this can be hard to do if your Honeywell programmable thermostat decides it’s ready to stop cooling your house. If your Honeywell thermostat is not cooling it most likely has to do with one of the following:
- Insufficient airflow to your heating air conditioning system.
- Issues with the compressor.
- Wiring on the thermostat.
- Your furnace/heating system can affect your system’s ability to cool.
- The thermostat device itself could be messed up.
While any number of these things can be the problem, it’s important to double-check the obvious things that could cause your thermostat to not engage your home’s air conditioning unit.
- Verify that the thermostat’s temperature is set lower than the current temperature indoors this should engage your air conditioner.
- Make sure the circuit breaker switch(es) for your HVAC system is turned on.
The first thing you want to do is make sure that there is nothing blocking the air handler for your system. The airflow coming out of your home’s ventilation system can be a good indicator of what the possible problem could be. To check this you just want to go to one of the vents in your home and feel the air coming out of them.
- If there is no air coming out of your vents it could be a problem with your heater or furnace.
- Room temperature air coming out of the vent is usually indicative of an issue with the compressor.
- If warm or hot air is coming out of your vents this could be a sign that the thermostat was wired incorrectly. This is a common problem with new installations.
A number of things could be happening to the compressor in your heating and cooling system that could be causing it not to cool your house down.
The first thing you want to check is the thermostat itself and make sure that you don’t see a snowflake, or blinking “Cool On” emblem on the screen. This means the system is in delay mode and it should be back up and running in no more than five minutes.
If this is not the case you need to listen for your compressor to see if it’s turning on or not. If the compressor is turning on but your vents aren’t blowing cool air you could have a problem with the thermostat device itself. If this is the case you will want to contact us here by phone or live chat.
If the compressor on your HVAC system is not running your thermostat could be wired incorrectly. If this is the case you may want to reference the owners and installation manual for the proper wiring guide.
Wiring issues with your new thermostat can prevent it from blowing cool air and in fact may even cause your system to blow out hot air even when it is set to cool. These problems are usually found in new installations and can be rewired correctly by following the wiring guide in the owners or installation manual.
The furnace or heat pump system in your home can cause issues when it comes to your HVAC system’s ability to cool a space down.
- The first thing that you want to do is to make sure that the circuit breaker switch to your furnace is turned on.
- Next, you want to locate the actual furnace and make sure that it itself is turned on.
- Make sure that the cover is on the front of the furnace. Some units won’t turn on if the cover is not all the way on.
Even though it may be powered on, your thermostat itself could be the reason that your system is not cooling.
- Ensure that your device is connected to Wi-Fi if you are trying to make your system cool from a wireless device.
- Make sure that your device doesn’t need a battery change. Having a low-power level can cause your thermostat to have issues communicating with your HVAC system.
