FURNACE INSTALLATION IN HAMILTON
Old furnace struggling to keep up or costing too much on gas? We design and install properly sized, high-efficiency gas furnaces that keep Hamilton homes warm, quiet, and efficient. Our licensed gas fitters handle removal of the old unit, permits, venting, gas work, and start-up so your new furnace installation is safe and up to code.
Quick Checks Before You Replace Your Furnace
Before you assume you need a brand-new furnace, run through a few safe checks.
Sometimes a simple fix or repair can buy you a few more seasons.
Thermostat settings
Make sure the thermostat is set to Heat, the temperature is above room temperature, and the fan is on Auto or On. Replace the batteries if it has them.
Furnace switch and breaker
Confirm the furnace switch (often at the top of the basement stairs or beside the unit) is on, and check that the breaker has not tripped. Don’t keep flipping a breaker that trips more than once.
Filter and vents
Check the furnace filter. If it’s clogged with dust, replace it and make sure supply and return vents are not blocked by furniture, rugs, or boxes.
No-heat troubleshooting
If the furnace still won’t start, is blowing cold, or is short cycling, use our No-Heat Triage & Code Helper on this page or visit our Furnace Repair page for emergency help.
Age and safety warnings
If the furnace is 15+ years old, has been red tagged, or a tech has mentioned a cracked heat exchanger, it’s time to plan a replacement, not another band-aid repair.
CALL FOR A REPAIR OR REPLACEMENT QUOTE
If you’ve worked through these checks and still have no heat, or your furnace is 15–20+ years old with repeat problems, it’s time to get a professional opinion.
What we install and replace today
We install properly sized, code-compliant furnaces for most Hamilton homes, from post-war bungalows to newer two-storey builds and townhomes.
High-Efficiency Gas Furnace Replacement
Swap out your tired mid-efficiency or builder-grade furnace for a modern high-efficiency model. Proper sizing, venting, and gas piping for safe, quiet operation and lower gas bills.
Good / Better / Best Furnace Options
We walk you through clear choices: a solid “good” option, a quieter “better” two-stage model, and a “best” variable-speed furnace that pairs well with future AC or heat pump upgrades.
Furnace and AC or Heat Pump-Ready Installs
Planning to add or upgrade central air next? We design your new furnace so it works smoothly with today’s high-efficiency AC and heat pumps. No surprises when you cool the home later.
Basement, Townhome, and Tight-Space Installs
Short on space around the furnace? We’re used to tight basements, bulkheads, and utility rooms. We choose cabinet sizes and venting that actually fit your home, not just the box label.
Upgrades to Venting, Drains, and Gas Piping
New furnaces often need updated PVC venting, condensate drains, or gas piping. We handle these upgrades and can coordinate with our Gas Pipe Installation team when needed.
Furnace Replacement with Hydronic or Boiler Tie-Ins
Have in-floor heat or a boiler working alongside your forced-air system? We can coordinate your furnace install with Boiler Installation
How furnace installation works with Greg’s
Here’s how we go from your first quote to a clean, code-certified furnace installation and a warm, even home in Hamilton.
Home and Load Assessment
We start by looking at your existing furnace, ductwork, and venting, and by asking how the home actually feels in winter. For many Hamilton homes, we perform a load calculation and check duct sizing so we are not just matching the old nameplate.
Options, Rebates, and Written Quote
You get clear “good / better / best” furnace options, including efficiency ratings and warranty terms. We explain any current Ontario or utility rebates that may apply and provide a written installed quote — no hourly rates.
Scheduling and Permits
Once you approve the quote, we schedule a date that works for you. We pull required permits and follow Ontario gas and building code requirements so your installation is inspected and properly documented.
Removal and Clean Installation
On install day, we protect floors, remove and dispose of the old furnace, and install the new one with proper venting, gas connections, and drains. We reconnect ductwork carefully and keep the work area tidy.
Start-Up, Testing, and Homeowner Walkthrough
We test gas pressures, safety controls, and airflow, then start the furnace and verify temperature rise. You’ll see how to use the thermostat, change filters, and set fan options. We answer every question before we leave.
Warranty Registration and After-Install Support
We register equipment warranties and keep your installation details on file. If you ever need Furnace Repair or annual maintenance later, we already know your system.

Hamilton Furnace Installation: Safe Sizing, Pro Installs, and When to Replace
SAFE DIY CHECKS
REPAIR VS REPLACE
- Age of your current furnace
- Under ~10 years old with its first issue? A repair usually makes sense.
- Around 15–20 years old with repeat problems? We’ll talk seriously about replacement.
- Cost of the repair vs furnace value
- If a repair is close to, or more than, 25–30% of the cost of a new furnace, especially on an older unit, replacement is often the smarter long-term move.
- Red tags and safety concerns
- Heat exchanger cracks, serious venting issues, or gas safety concerns are reasons to retire a furnace. We’ll explain what your gas utility or inspector has found and how a new furnace fixes the root problem.
- Comfort and efficiency goals
- If your home has cold rooms, noisy operation, or high gas bills, a new furnace with proper sizing and duct adjustments can be a big upgrade in comfort, not just a swap of metal boxes.
- Your budget and timing
- We lay out clear “repair now, replace later” vs “replace now” options with real numbers, so you can decide what fits your budget and risk tolerance. No pressure, just straight talk.
WHEN TO WHEN TO BOOK A QUOTE
You don’t have to wait for a full breakdown to talk about a new furnace. Booking a quote early often saves money and stress.
- Your furnace is 15+ years old
If the system is nearing the end of its typical life in Ontario, it’s smart to get a quote while it’s still running. That way you can choose a replacement on your schedule, not on the coldest night. - You’ve had two or more repairs in the last few winters
Frequent inducer, board, or blower repairs are a sign the furnace is wearing out. A free-standing quote lets you compare the cost of another repair vs a full upgrade. - The furnace was red tagged or flagged by another tech
A safety red tag, warning about a heat exchanger, or serious venting concern is a strong reason to plan a replacement. We can often provide a temporary safe solution while we schedule the new install. - Comfort or noise is an everyday problem
Uneven temperatures, short cycling, or a very loud blower point to sizing and duct issues. A new, properly sized furnace with better controls can fix comfort problems you’ve “lived with” for years. - You’re planning other upgrades
If you’re finishing a basement, replacing windows, or upgrading AC or a heat pump soon, it’s a good time to look at the furnace as part of the bigger picture. We’ll design the system so everything works together.
