Heat that holds all winter
All Service London installs, services, and repairs furnaces, boilers, and heat pumps across London and Middlesex. From a no-heat emergency in January to a high-efficiency replacement, our HVAC crew keeps the heat on.
A furnace in the London area works hard for half the year, and an aging unit costs more to run every season while it edges toward failure. We assess whether a repair will hold or a replacement is the honest answer, and we size high-efficiency equipment to the home, not to a one-size-fits-all chart.
Beyond the furnace, we service boilers and in-floor heat, install and tune heat pumps (the lower-cost backup for mild shoulder seasons and a real option for well-insulated homes), and handle the gas and electrical connections, permits, and venting the work demands.
