Here are 6 common causes of a condo heater blowing cold air, and what you can do to fix it.

  1. Check the Thermostat Setting

The first thing you should check is the thermostat setting. Make sure it is set to the desired temperature and is in the “heating” mode. If it’s set correctly, but the heater is still blowing cold air, move on to the next step. Please note that If the thermostat is recently installed, you must ensure that the thermostat meets the HVAC system manufacturer’s recommended settings. During the setup & wiring process, you always must follow certain instructions for different condo HVAC systems.

  1. Ensure Proper Power Supply

Ensure that the heater is properly plugged in and that the circuit breaker hasn’t tripped. If the breaker has tripped, reset it and see if the heater starts blowing hot air.

  1. Replace the Dirty Air Filter

A dirty air filter can restrict airflow, causing the heater to blow cold air. If you haven’t changed the air filter in a while, replace it with a new one. You should replace the air filter every 6 months, or more frequently if you have pets or allergies. Check out our article about How Regularly Changing the Air Filter in Your Condo – Toronto & GTA

  1. Check For Gas Smell

If your condo uses natural gas to operate, you must always check it by a licensed gas technician. Your condo should always be equipped with a CO detector in case there is an unsafe condition with your gas heater. If you’re not comfortable doing this yourself, call a professional Condo HVAC technician for help.

  1. Repair or Replace the Fan

The fan in your heater may be broken, preventing it from blowing hot air. You may feel heat radiate from your unit but no real airflow. If you think this is the case, call a professional HVAC technician to diagnose and fix the fan or replace it.

  1. Check For Water Leaks

If none of the above steps solve the problem, the heater itself may be leaking water or there is a clogged drain as a result of leakage. Some Condo Heating Systems are equipped with water overflow sensors. The sensor will cut the power to the unit until the system is repaired or replaced. If this is the case, call a professional HVAC technician right away to diagnose and address the issue.

In conclusion, if your condo heater is blowing cold air, don’t panic. Follow these steps to diagnose and fix the problem, or call a professional Condo HVAC Company for help. Remember, a well-maintained heating system is essential for keeping your condo warm and comfortable during the colder months.
