Polar Vortex


I’m writing this post at the beginning of March 2019, and the current outdoor air temperature is -32 Celsius. It’s damn cold out!

When the temperatures hit this level, your HVAC system is working overtime to keep your house warm and comfortable. In my home, the furnace has literally not shut down for about two weeks.

Often times, homeowners will “test”their furnace in late September by turning on the heat when it gets a little chilly at night. It cycles on and runs for five minutes and shuts down having done its job. Everything is fine.

But when the real Canadian winter hits, your furnace is being put through a severe stress test. That’s when the machine has to work its hardest to maintain the temperatures in your home – and this is when the weakest link will fail.

When you contract with a HVAC company to properly test your furnace, we use electronic test equipment that physically tests the gas pressures, air flow pressures, exhaust gas makeup and temperatures, and the running voltages and amperages of the furnace, and compare those readings to the manufacturer’s specifications. If anything is out of range its an indicator that the unit will require tuning and perhaps some replacement parts.

The UEI DL489 digital multimeter, one of the test tools in our arsenal to measure and assess the performance of your HVAC equipment.

Unless you own several thousands dollars worth of electronic test equipment specialized for the HVAC trade, and you know how to use that equipment, then judging the operating condition of your furnace by giving it a test run can be very misleading. You might believe that your furnace is ready to face the winter, when in fact it might be struggling.

The best defense is a good offence.

Instead of guessing whether your furnace is going to operate trouble free throughout the winter, why not schedule a HVAC professional to give your furnace a thorough tune up before the cold winter weather settles in? You will avoid emergency service call fees, as well as delays in getting parts for your furnace. In the worst case scenario you might have to deal with frozen plumbing pipes and the expenses that come with water damage.

The least costly method of keeping your HVAC system performing well is to have it serviced once a year. 404 Refrigeration & HVAC Services offers furnace and air conditioning system tune-ups year round to our present and new customers.
