What London Homeowners Say About Our Smart Thermostat Installation
"Had Abdullah install an Ecobee Premium with remote sensors. Our Masonville home had hot and cold spots—the sensors balanced everything perfectly. He handled the Enbridge rebate paperwork and we got $125 back. Our heating bills are down 18% this winter. The app is easy to use and the geofencing works great. Professional installation was worth every penny."
— Holt B. Masonville, London ON · January 2026
"Our old thermostat died in December. Called Hawana for a Nest installation. Abdullah arrived same day, installed in an hour, and showed us how to program winter settings. The learning feature figured out our schedule within a week. Our gas bill dropped 15% compared to last year. Great service and honest advice on which model was best for our home."
— Tors K. London ON · December 2025
"We didn't have a C-wire in our older St. Thomas home. Abdullah installed a Honeywell T9 with a C-wire adapter. He explained the process clearly and had everything working within 2 hours. The geofencing automatically adjusts when we leave and return. Our heating bills are noticeably lower. Professional install was definitely worth it—would have struggled with DIY."

Abdullah Ghzail – Owner & Lead TSSA-Certified HVAC Specialist
"I've installed hundreds of smart thermostats across London and Southwestern Ontario. The difference between DIY and professional installation comes down to the C-wire. Most older London homes don't have one. I've seen too many homeowners struggle with compatibility issues or damage their furnace control boards. Let us handle the installation, C-wire adapter if needed, and rebate paperwork. You'll get the savings without the headaches."

Many of our customers see the difference in their first gas bill after installation.
Most smart thermostats require a C-wire (common wire) for continuous power. Many older London homes built before 2005 lack a C-wire. If your home doesn't have one, we can install a C-wire adapter during professional installation. DIY installation without a C-wire may result in compatibility issues or incomplete setup. We check for C-wire during our assessment and include the adapter if needed at no extra charge.
Nest Learning Thermostat learns your schedule automatically and has a sleek design—great for simplicity and Google Home users. Ecobee includes remote room sensors for balancing temperatures across different rooms, ideal for larger London homes with hot and cold spots.

Most smart thermostats work with standard 24V HVAC systems including gas furnaces, central AC, heat pumps, and boilers. Older systems or millivolt systems may have compatibility limitations.
