Troubleshooting Guide

SPLIT AIR CONDITIONERS AND HEAT PUMPS

  • Check to make sure that your thermostat is set in the “cool” position.
  • Ensure that your outdoor air conditioning (condensing unit) is running: Check the circuit breakers in the circuit breaker box (or electrical panel), most likely mounted to an outside wall in the back of the house. Are they in the “On” position?
  • Check the outdoor unit “disconnect switch” to make sure it is in the “ON” position. The disconnect switch is located near the outdoor unit. (Typically a grey 8″ wide x 16″ high x 4″ deep box mounted to the wall).
  • Ensure that the blower motor in your furnace is running. (If the thermostat is in the “cool” position, the furnace blower should be running.)
  • If not, check to make sure the on / off switch at the furnace is in the “ON” position
  • Be sure that you have changed the filter in your furnace recently.
  • An extremely blocked filter can cause your outdoor air conditioner unit to shut down due to lack of proper airflow.
  • Your filter should be changed every month.
  • Check all return air grilles to make sure they are not blocked by furniture.
  • Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).

 

GAS AND ELECTRICAL FURNACES

  • Check to make sure that your thermostat is set in the “heat” position
  • Make sure that the temperature setting on the thermostat is set above (or higher than) the indoor temperature showing on the thermostat. This tells your heating system that it should provide heat!
  • Ensure that there is power in the furnace:
  • Try switching on the fan using the fan switch on the thermostat.
  • Check the circuit breakers at the electrical panel to make sure they are in the “On” position.
  • Check the SSU switch (it looks like a light switch in a gray box on the furnace) to make sure it is in the “ON” position
  • Replace the furnace filter if needed.
  • All 1” thick furnace filters should be replaced monthly.
  • Purolator 2” thick and other high-capacity pleated filters can usually be changed every other month or just 6 times per year.
  • If the system is running but you have not changed your filter, the filter may still need to be replaced.
  • Check all return air grilles to make sure they are not blocked by furniture.
  • Check all supply air registers to make sure they are open and blowing air. (The return air grilles are normally located on your walls and are wide and flat).

    Brian is very easy to work with, his advise about which gas stove to go with was excellent and my parents ending up going with the high-end Regency model. His installers were very good and were easy to talk to about the job and they did an excellent job. I like it when a contractor works with their customers and cares about their company to back up the work done. I highly recommend them and a special thank you to Brian who runs an excellent company! My parents are extremely happy and can't wait on those cold nights to go by to feel the warm heat of their new stove.

    This company has excellent products and even better service, and it shows through client interaction. They care about their customers and complete their work in a timely fashion. Best of all they leave the work area in cleaner condition than when they arrived.

    Their showroom has items you can't even imagine.

    I have used Cozy Comfort Plus many times, personally purchased the following from them:
    -Furnace
    -A/C unit
    -Air cleaner and purifier
    -Tankless water heater
    -Fireplaces (Mantles)
    -Fire table and
    -BBQ

    Brian and his team are my go to.

    My furnace broke mid February and from the first call Cozy Comfort Plus exceeded my expectations and it was the best customer service experience I've had in a very long time. They had someone here within two hours who very knowledgeable and gave me several options. I ended up deciding to replace my furnace and they had it done the next day. From my first contact on the phone, to the technician to the installation staff they were all professional, responsive and truly a pleasure to work with. In a little over 24 hours the heat was back on and at a very fair price.

    I cannot recommend them highly enough as it's a stressful time when your furnace goes mid February. They even submitted the rebates before I had a chance to call them the next day!! All I can say is WOW.
