( A little known secret that will save you up to a thousand dollars in repairs.)
Most Winnipeg Homeowners have Central air conditioning in their homes. Even though they may only get used a few months of the year, our summers will get to +30c days and loads of humidity making it a modern day necessity. Most workplaces are Air Conditioned and it would then be difficult to go home to an unconditioned space.
The most common failures with Central Air systems stem from the lack of maintenance. Filters need to be replaced on the indoor furnace or air handler so that the cooling coil (Evaporator) stays clean. The outdoor condenser needs to stay clean as well. Rinsing off once or twice during the heating season with the garden hose most often is enough.
A less common failure that may not always become apparent at the time comes from turning on the air conditioner and having the compressor try to start in the cold weather. Larger commercial units will generally have built in protection having low pressure and low ambient cut out controls along with a crankcase heater. Residential Central Air Conditioners of all makes and models are most often not provided with low temperature protection.
Imagine a family gathering for Christmas or New Year’s. It is -30f outside and with all the people and cooking going on its nearing + 30f in the kitchen! Someone turns on the air conditioner and ugh!! The compressor oil is like tar and cannot possibly start in -30f weather. It keep trying to start and eventually may run and damage itself in the process. Even a small amount of run time will shorten the life of the compressor at those temperatures.
A simple solution to this would be to turn off the breaker or A/C service switch at the unit. But what happens if just like a lot of busy homeowners get busy and simply forget just that one time? Our secret today is a simple one that Tradesman Mechanical includes with all of our Central Air Conditioning Installation is a Low Ambient Cut out control. It is a temperature sensor that will open the control circuit as the temperature drops below 45F and will not reset or close until the temperature rises past 55F.
Call us today to have a low ambient control installed on your unit and eliminate the risk of this type of damage. 204-888-2020
