A Warm Home Starts With the Right Install
Most furnace problems do not start with a bad unit. They start with a bad installation. An oversized furnace short-cycles and burns out fast. An undersized one runs constantly and still cannot keep up. A poorly vented system increases the risk of carbon monoxide over time. At GHQ Mechanical, we do not skip steps. We assess your space, match you with the right system, and install it the way it was designed to be installed. TSSA-certified, code-compliant, and built to last through the season and the ones after it.
When To Replace
Is It Time to Replace Your Furnace?
Most furnaces have a lifespan of 15 to 20 years. But age alone is not always the deciding factor. Here are the signs that a replacement makes more sense than another repair.
Your heating bills have been climbing without explanation
The unit is running constantly, but struggling to maintain temperature
You are calling for repairs more than once a season
The heat is uneven from room to room
The furnace is making unusual sounds like banging, rattling, or clicking.
The unit is more than 15 years old and running on an outdated efficiency rating
What's Included
What Our Furnace Installation Includes
We follow the same process on every furnace job. Assessed, installed, tested, and walked through before we hand the job back to you. Here is exactly what that looks like.
Home Assessment
In-home assessment and furnace sizing based on your square footage and insulation
Efficiency
High-Efficiency Furnaces That Actually Pay for Themselves
Older furnaces typically run at 60 to 70 percent efficiency, meaning a significant portion of the gas you pay for is lost through the exhaust. Modern high-efficiency units operate at 95 to 98 percent AFUE, converting nearly all the fuel into usable heat. Over the course of a Hamilton winter, the difference on your gas bill is noticeable. We help you understand the numbers upfront so you can make a decision that makes sense for your budget and your home.
