We’ve helped hundreds of Guelph homeowners upgrade aging systems that struggled during last winter’s deep freeze. One recent customer in West End Guelph told us their previous furnace was inefficient and unreliable, driving up energy costs. After installing a high-efficiency Carrier Infinity furnace paired with a heat pump, they noticed a 25% reduction in monthly heating bills and consistent warmth—even on the coldest nights. Another family in Kortright Hills appreciated our 24/7 emergency service when their AC stopped working during a July heatwave. Our team arrived promptly, diagnosed the issue, and had their Trane air conditioner running again the same day.
Beyond quality products and expert installation, we help homeowners maximize savings by guiding them through available government rebates, which currently exceed $7,100 for eligible HVAC upgrades. This financial support makes switching to energy-efficient systems more affordable, especially important in our climate where both heating and cooling demand can be high.
