Furnace and air conditioning service in Grimsby

Yes, if you mention both when you book. A combined visit is usually a maintenance call, where the technician checks the furnace burner, venting and filter along with the outdoor unit and the condensate drain. If one of them has an actual fault, say so up front so the right parts and time are planned, and you will see a written price before any repair goes ahead.

It needs checking. In the Glenlea, Buchan Court and Renwood Park surveys, many houses started on oil, moved to gas, then got a high-efficiency furnace that vents out the side wall. That leaves the gas water heater venting alone into a chimney sized for far more heat, where flue gases cool, condense and can backdraft into the basement. In the Griffin Survey and the McMonnies and Stock Survey, unlined masonry chimneys can also be damaged by that condensation. Look for soot, rust or moisture around the water heater's draft hood, and if you see any, book a check through furnace installation and replacement.

Cold outdoor air holds very little moisture. At the Hamilton RBG station near Waterdown, the 1981-2010 normal daily average is -4.7 °C in January, so the furnace spends months warming dry air. In newer Waterdown South and Waterdown Bay houses, an HRV that is out of balance can bring in more outdoor air than the house needs. In older houses, drafty windows and doors do the same. Static shocks, cracked wood trim and dry throats are the usual signs. Pick up an inexpensive humidity meter, watch the reading for a week, then read our guide to humidity in winter and summer.
