Is your condo HVAC no working?

Check the condominium documents and management’s instructions to confirm responsibility for in-suite repairs.

We understand that it could be frustrating to have problems with your condo heating unit when you need them the most during the coldest times of the year. Especially when it’s hard to find the right HVAC Technician to fix the problem. Sometimes the problem is simpler than what it looks like. Therefore, we recommend trying the following before calling a Condo HVAC Technician. 

Start with the normal controls, an accessible filter and building notices. Follow the installed model’s instructions for any permitted reset.

1. Reset Your System From The Electrical Breaker Panel Box

Use only the reset procedure specified for your installed model. Do not operate unidentified breakers or open electrical panels. If a breaker trips or the fault returns, stop resetting and arrange service.

NOTE: Sometimes there could be a time delay on the thermostat. Please allow at least 20 minutes before you test the heating again. 

How Do I Test? Just a simple check. Put the thermostat on the heating mode. Change the 80F 27 Celsius. After 20 minutes, Hold your hands close to the air vents to feel the airflow and temperature of the system.

2. Make Sure The Filter Isn’t Dirty

Dirty filters restrict air circulation throughout your home. Hence, the system will high pressure on restricted air circulation & ultimately cut off the power to protect itself from overheating. If you have a fan coil system, you could burn your fan motor.

3. Check Your Building Common Area For An Emergency Notice

Building managements or superintendents often post emergency announcements in the common areas of the buildings such as lobby or elevator to let the residents know about any upcoming central HVAC shut down due to Emergency, maintenance, or annual switch over from heating to cooling or cooling to heating.

Some In-suite HVAC systems are connected to the building central pump, boiler & chiller systems. If your building HVAC or plumbing system experience malfunction due to mechanical problems, then your in-suite HVAC system can be affected until this problem is fully addressed. 

A condo HVAC specialist can assess whether the fault involves the in-suite equipment, a shared building system or both.

Questions about this topic

Can I Use My Condo Heating & Air Conditioning All Year Around?

  1. If you have a 2-Pipe Fan Coil System, you can either use heating or cooling at one time. Most buildings switch to air conditioning sometimes in May & June and Switch to heating in September & October. Learn more about 2 pipes versus 4 pipes fan coil here.
  2. Water source heat pump systems are connected to independent water loops in the building. The water is responsible to keep the compressor from overheating in summer or regulate the compressor from freezing in the wintertime. If the water temperature or water flow level fluctuates, your system automatically shuts down to protect the compressor from complete failures. 
  3. If You own a Condo Pack or Magic Pak Unit, can use Heating & Air Conditioning year-round. 
  4. If you own a PTAC unit, you can also use Heating & Air Conditioning All Year Around.
