About the work
How Grimsby Heating and Cooling works on a system
A furnace or air conditioner rarely fails without a cause that can be measured. A visit from Grimsby Heating and Cooling starts with the symptom as you describe it, then moves to the readings that confirm or rule out each possible cause: gas pressure at the valve, temperature rise across the heat exchanger, static pressure in the ducts, the current a motor draws, and on an air conditioner the refrigerant charge. The faulty part is named, shown to you where it can be, and the repair is priced in writing before anything is fitted. See furnace repair for how that plays out on a no-heat call.
Who may do the work is set by law. Gas appliances in Ontario are covered by O. Reg. 212/01 and installed to the CSA B149.1 Natural Gas and Propane Installation Code. Work is performed by TSSA-certified gas technicians. Air conditioners and heat pumps carry refrigerant, and refrigeration and air conditioning is a compulsory trade in Ontario. For refrigeration and air conditioning: Work is performed by 313A refrigeration and air conditioning mechanics.
Grimsby's houses come from three periods, and each changes the job. The cottages of Grimsby Beach and the older houses along Main Street often have equipment and ductwork squeezed into spaces never built for them, and chimneys that may need relining before a new gas appliance can vent into them. The post-war houses of Lakemount Terrace tend to have undersized ducts and weak return air, so a bigger furnace is not always the fix. The newer homes of the west end have condensing furnaces with plastic side-wall vents, condensate lines and heat-recovery ventilators, which is why a maintenance visit there looks closely at vent terminations, condensate traps and ventilator filters.
When replacement is the better answer, the new furnace or heat pump is sized from a heat-loss calculation and an assessment of the duct system, not from the label on the old unit. If a repair is still worth making, you hear that too, with both prices side by side so you can decide. Heat pump quotes include a check of the rebate programs open at the time. To start, ask for a quote or send us the details.
Standards we work to
- The fault is measured and named before a part is priced.
- Gas work follows the CSA B149.1 installation code under O. Reg. 212/01.
- Replacements are sized from the house and its ducts, not the old label.
- Venting and chimney condition are part of every furnace replacement quote.
- We point out where the Ontario Fire Code expects a carbon monoxide alarm next to sleeping areas.
- If a repair makes more sense than a replacement, you are told so.
A measured diagnosis comes before the price
Tell us what your furnace, air conditioner or heat pump is doing. The technician measures, explains the cause and writes down the price before any work begins.
