Heating & Air Conditioning Troubleshooting

Troubleshooting Your Heat Pump

Your thermostat and heat pump will do the work for you. TheHeatmode operates the heat pump;E Heatis your furnace;Coolis air conditioning. The auto feature allows you to set the temperature at which you want your heat to come on and the temperature you want the air conditioning to come on. This is very handy in the spring and fall when temperatures at night can vary greatly from the daytime temperatures.


When the outdoor temperature drops below a preset temperature, usually -7°C, the heat pump will shut down and the thermostat will call the furnace to supply your home with heat. When the outdoor temperature rises above this set point, the thermostat will switch back to the heat pump automatically.


For maximum savings, we recommend that you maintain your house at a constant temperature, day and night. If you prefer a cool nighttime temperature of more than 2°F difference from the daytime setting, we recommend shutting your bedroom door and closing the supply air vent. If you have a programmable thermostat, you can step up your house temperature using the program mode, giving the heat pump two or three degrees an hour to reheat your home!


In the summer it is recommended that you set your thermostat to around 24°C or 74°F; any cooler could make some members in your household too cold and may cause freezing of the indoor coil.


In the case of a heavy snow fall, clear the snow away from the heat pump (about 3 feet clear) and clear away any snow that may have accumulated on the top of the heat pump.


Our heat pump keeps starting and stopping and only the furnace fan is running – we have no heat!

Check your furnace filter to see if it needs to be changed. If the filter is too dirty, air will not flow through the indoor coil properly, causing a high-pressure situation that causes the heat pump to shut the system down.


After changing your filter, you may need to turn off your furnace breaker for 30 seconds to reset the high- and low-pressure switches. If this happens again within a month, contact us to check out your system.


The heat pump makes a horrible noise and steam is rising out of it.

Not to worry – it is only the defrost mode. This happens every hour or as needed and will last up to 3 minutes, depending on outside temperatures.


The heat pump has ice building up on it.

This may be normal operation as the heat pump will defrost itself when necessary. In the case of heavy ice buildup, please contact us for service.


The furnace is coming on instead of the heat pump.

Check the outside temperature – if it is below set point, the heat pump is programmed to shut down and let the furnace heat your home.


The heat pump is not working.

Check your thermostat and ensure you are not in E Heat (furnace) mode or A/C mode or that someone has accidentally pressed the HOLD button. Contact us for service.


Air Conditioning Troubleshooting Guide

We recommend you set your thermostat between 74° or 75° - keep in mind we are trying to air condition your home, not create refrigerator conditions. This temperature will keep everyone comfortable without creating a dangerous situation when you exit the home and enter very hot conditions outside. If you have a thermostat that has an auto mode you can set your heat to come on between 65° and 72° and set your cooling to 74° or 75°. Then when the house is too cool or too warm either the furnace will come on to provide heat or the air conditioning will come on to cool your home.


If your home gets too hot and you have waited too long to turn on your air conditioner, it may not be able to keep up to the heat load. You will have to wait until the outside temp comes down and try to operate the air conditioner then next day.


If you experience problems with your air conditioner, check these first:

  • Is your thermostat set in the "cool" position?
  • If so, is your outdoor air conditioning unit running?
  • Did the circuit breakers in the circuit breaker box (or electrical panel) trip to the “OFF” position?
  • Is the outdoor "disconnect switch" on your outdoor unit in the "ON" position? The disconnect switch is usually a small metal grey box mounted on a wall near the outdoor unit.
  • Is the blower motor in your furnace or air handler running when your thermostat is activated? Make sure the furnace switch is in the "ON" position.
  • Have you changed your filter? A blocked filter can cause your unit to shut down due to lack of proper airflow.
  • Are the air registers (supply or return ducts) plugged?


Gas Furnace Troubleshooting Guide

York furnaces have a diagnostic light – in the case of a problem, it is helpful to not turn off the power to your furnace until you have recorded how many flashes are present. If you smell gas, turn off your furnace immediately by the power switch or breaker box and contact us and Fortis Gas right away.


If you experience problems with your heating, check these first:

  • Is your thermostat set in the "heat" position?
  • Is the temperature setting on the thermostat set higher than the thermostat's indoor temperature?
  • Is the power turned on for your furnace? At the thermostat, turn the fan to "ON." The fan should run when power is being supplied to furnace.
  • Did the circuit breakers in the circuit breaker box (or electrical panel) trip to the “OFF” position? Check the SSU light switch on the grey box located at the furnace to make sure it is in the "ON" position.
  • Have you changed your filter? A blocked filter can cause your unit to shut down due to lack of proper airflow.
  • Are the air registers (supply or return ducts) plugged?
