About Welland heating and cooling
Welland has a lot of older housing stock, particularly in Dain City, Crowland, and the downtown area. Many of these homes have furnaces installed in the 1980s and 1990s that are still running today. They are workhorses, but they wear in predictable ways: igniters, flame sensors, blower motors, and control boards are the common failures. A proper diagnosis before any repair is what separates a reasonable bill from an unnecessary replacement.
The AC side of the picture matters too. Welland gets genuine heat waves in summer, and a central air conditioner that is running but not cooling is the most common summer call. In most cases the fix starts with the filter, the outdoor condenser, and the thermostat, before any technician is needed.
A note on how this guide works
This guide is published by Living Websites, a Niagara-based web-services company. The information here draws on publicly available Ontario market data, TSSA licensing information, and general HVAC knowledge. It is not affiliated with any specific contractor, and cost ranges are illustrative, not quotes.
Before any furnace or gas work, confirm the contractor holds a current TSSA gas technician licence. For rebate-eligible work, confirm the equipment and contractor are on the official program's eligible list before signing. See the FAQ for more on rebates.

Why is my furnace running but not blowing hot air?
Usually one of three things: a thermostat set to ON instead of AUTO so the fan runs without a heat call, a clogged filter that tripped the high-limit switch, or a furnace locked out after a failed ignition. Check the filter and fan setting first. If the burners still will not light, that is a service call because it involves the gas valve.
My AC runs but the house will not cool. What is wrong?
The two most common summer causes are choked airflow from a dirty filter or coil, and low refrigerant from a slow leak. A frozen coil will also stop the cooling while the unit looks fine. Shut it off, let any ice melt, change the filter, and if it still will not cool, book a diagnostic. The full troubleshooting checklist is on the AC heat-wave guide.
How much should furnace or AC repair cost in Welland?
Most common repairs in Ontario land between $150 and $650 in parts and labour. A diagnostic visit is typically $90 to $150 and is often credited to the repair if you proceed. A full furnace replacement typically runs $3,000 to $8,500 installed, a heat pump higher, before rebates. See the full cost guide.
