  • Tips and hints from G.M. Mechanical!
    Water heaters are being hit hard with tariffs right now to the point where if you have a Power, Direct-Vent water tank, the unit is of a comparable cost to a tankless water heater. The only thing is, with a tankless water heater, you can still get up to a $1000.00 rebate from the Alberta government. If you don’t have a/c and want to keep your house cool, keep your blinds closed during the day, open the windows at night to help your house cool down. Also, run your furnace fan to help circulate air from the basement to the rest of the house. If you got a new furnace after the flood, your warranty might be running out this year. Book a Maintenance service call to potentially spot any issues before the parts are no longer under warranty! One way to check for water leaks is to watch your water meter. There should be no movement over 2 hours of no water use. Irrigation systems and lawn services usually leak water into/onto the ground, but over a 24 hr period can amount to a lot of water wasted. Irrigation lines should be blown out and air tested every year (usually in the fall). And lastly… please change your furnace filters often if you are completing a summer home renovation project. Drywall dust and other construction dust can wreak havoc on a furnace when it comes time to start again in the fall! As always, if you have any questions or need our help, please call G.M. Mechanical at 403-652-1282 or visit www.gmmech.net.
