Troubleshooting
Are you having air conditioner issues?
It may take several hours to cool your home to the desired temperature depending on the outdoor temperature, humidity level, and desired thermostat temperature. Your air conditioner is not designed or expected to maintain an indoor air temperature cooler than 24°C or 75°F. Checking the vents for cool blowing air will be a more immediate indication of your air conditioner functioning than the temperature changing on your thermostat.
Your air conditioner is intended to maintain cool air for long periods of time, it is not advised that you turn the system on and off daily as the system will need to work harder to remove the heat and humidity that build. Your air conditioner should not be turned on unless the outdoor temperature is at least 16°C or 61°F to avoid damage to the unit.
These steps are done at your thermostat and ERV/HRV wall control:
Check / Change the batteries in your thermostat. If the thermostat is blank or black it may be due to no power, you could proceed to the mechanical room steps and then return to the first step once they are completed.
Make sure the thermostat is set to cool and the desired temperature is lower than the current indoor temperature. Your air conditioner is not designed or expected to maintain a temperature below 24°C or 75.2°F in living areas.
Check if the thermostat is set to ON or AUTO. Thermostat set to ON causes air to circulate continuously and air exiting floor grilles will not always be cool.
Check that ERV/HRV is not set to MAX which may bring in more fresh air than desired, potentially making the area feel warmer or more humid.
Have you replaced your Builder Supplied thermostat? If so, have the company that installed it return to ensure the thermostat was wired correctly and is not the cause of the loss of cooling.
These steps are done outside:
Check that the electrical disconnect outside beside the condenser is set to ON and that there is wiring running to it.
Clean the outdoor condenser unit and be sure that there is no cover as it needs air entering to function.
These Steps are done in your mechanical area or room:
Check the furnace and air conditioner breakers on the electrical panel, make sure they are on.
Check that the air conditioner breaker has high voltage electrical wiring connected to it, if it does not, contact your builder for their electrician to attend to this.
Turn OFF your furnace at the power switch, this looks like a light switch and is in the mechanical area. It controls the power to your furnace. This may or may not be labeled.
Once the power switch is off, remove the filter and replace with a new filter. Leave the power off for at least one minute to allow the furnace to reset. You should change your filter monthly for highest efficiency and energy savings, a furnace should never run without a filter installed.
Turn the power switch back on.
Ensure all drain lines are free and clear of debris and are able to flow straight without kinks directly floor drain.
If your system shut down due to a dirty filter or outdoor condenser, you likely have a frozen coil which is the indoor air conditioning component installed above the furnace. The coil will need to thaw for 24 hours before another attempt to run the system can take place, you may notice water draining while the coil is thawing.
Once all of these things have been verified, if your system is still not blowing cool air, contact your builder service department
If you've had a recent power outage and have a Honeywell IAQ Thermostat that will not reconnect to wifi, try these steps.
