Between older Newton bungalows and new South Surrey builds, furnace quotes in Surrey can vary a lot; here's how to tell if yours is a fair one.

Quick answer
A furnace replacement quote for a Surrey home should reflect your specific property, whether that's an older bungalow with original ducting or a newer home with a more straightforward system, and should spell out capacity, labour scope, and permit responsibility rather than just a total number. If the quote reads like a generic estimate or the price sits well outside the general $4,500 to $9,500-or-more installation ballpark without explanation, a second opinion is worth arranging.

Surrey's housing stock is genuinely diverse, from 1960s and 1970s bungalows in Whalley and Newton with original ducting to newer, more efficiently laid-out homes in South Surrey and Clayton. Two quotes for furnaces of the same output capacity can legitimately differ if one home needs ducting modifications and the other doesn't, which is exactly why comparing quotes on price alone, without understanding the scope behind each number, doesn't tell you much.
Look for the furnace's recommended capacity and how it was determined, what's included in labour versus billed as an extra, whether any ducting or venting changes are part of the job, and who is responsible for pulling the gas permit. A quote missing these details is harder to evaluate honestly, regardless of the bottom-line number, and it's reasonable to ask the contractor to fill in the gaps in writing before you decide.
If your Surrey home has a secondary suite sharing or separate from the main furnace, make sure both quotes you're comparing are actually pricing the same scope; one contractor may be quoting just the main furnace while another has priced in suite ducting changes as well. This is a common source of quotes that look wildly different on paper but aren't actually pricing the same job once you look closely at what each one includes.
Furnace installation and replacement generally runs in a ballpark of $4,500 to $9,500 or more across the Lower Mainland, a starting point for comparison and not a fixed number, confirmed by the CANRO office after an assessment. A quote outside that range isn't automatically wrong, particularly for a home needing ducting work, but it should come with a scope explanation that makes sense.
A technician reviewing another quote looks at your existing furnace and ducting in person, checks the proposed capacity against your home's actual heat loss, and tells you plainly whether the scope and price you were quoted line up with what your home needs.
Most written quotes stay valid for a few weeks, which is generally enough time to get a second technician into your home without losing the original offer if you end up preferring it. If a salesperson is pushing hard for an immediate signature and resists holding the price even briefly, treat that pressure as information in itself, separate from whatever the actual number turns out to be.

Safety note
Any furnace work that involves the gas line, burner, or venting must be done by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870. If you ever smell gas or suspect a leak, leave the home first, avoid switches and phones inside, and call FortisBC at 1-800-663-9911 from outside before doing anything else.
The city's mix of older bungalows and newer homes means ducting scope can differ significantly between properties, even for similar-sized furnaces.
Roughly $4,500 to $9,500 or more as a ballpark, confirmed after an in-home assessment, not a fixed price.
Make sure both are pricing the same scope, especially if your home has a suite, since one quote may include suite ducting and the other may not.
Not necessarily; ask what's driving it, such as ducting modifications in an older home, and expect a clear explanation.
Call the office to discuss scheduling; a technician needs to see your furnace and ducting in person for an accurate comparison.
