Furnace Installation Vaughan - FAQs
My Vaughan house is only fifteen years old. Why is the furnace already going?
Builder-grade equipment is specified to satisfy code at the lowest delivered cost, which usually means an entry-level single-stage unit. It is not defective, it is simply the least expensive thing that met the requirement. Fifteen to eighteen years is a normal life for one. Because Vaughan built out in concentrated waves, whole streets reach that point together, which is why replacement feels contagious here.
Should I replace it with the same thing?
Not automatically. The original was sized and selected without much regard for how your particular house behaves, and newer Vaughan homes are relatively tight and well insulated, so the actual heat loss is often lower than the installed capacity. We run a heat loss calculation rather than matching the old nameplate, which frequently points at a smaller and better-modulating unit.
Will a better furnace fix my cold third floor?
It can help but it will not solve it on its own, and you should know that before you spend. A variable-speed unit runs longer at lower speed, which keeps air circulating and evens out the storeys noticeably. But if the top floor has no return air path, no furnace fixes that. We measure airflow per storey so you can see which part is the equipment and which part is the ductwork.
Is the existing venting and gas line reusable?
Usually yes for a like-for-like replacement, and it still gets verified. If we move you to a higher-efficiency or larger-input appliance the vent sizing and the gas line capacity both have to be rechecked, because builder gas piping was sized for the original appliance set and not for whatever you add later.
Do I need a permit to replace my furnace in Vaughan?
Not for a straight replacement. The City of Vaughan lists replacing an existing furnace among the jobs that do not need a building permit. A permit is required for new or altered heating, ventilation and air conditioning systems, such as new ductwork, and that application needs heat loss calculations. Gas work falls under TSSA rules either way. We tell you at the estimate which applies and handle the application when one is needed.
