Preventative maintenance is essential to keep any heating and cooling system running safely and at its full efficiency capability. As units age their components suffer wear, and chances are there will eventually be a failure. Having an annual inspection done by licensed HVAC contractors can mean the difference between you being comfortable and worry free all year round, and waiting for a part for your furnace at -25°C.
