We had a heat pump/AC unit installed by EHI, on time, on budget, great workmanship. Julian and team were knowledgeable and courteous. Dustin communicated well and is managing our government rebate for the new efficient system. Thank you Team!

Woodbridge Heating and Cooling for Big Homes and Busy Households
Three generations, one thermostat? Let's sort that out.
Woodbridge HVAC has a tough job: large family homes, long duct runs and often three generations under one roof, each with their own idea of the right temperature. We install quiet, high-capacity furnaces and heat pumps, add zoning, and even out big Ontario houses from the basement to the top floor. You get a written quote, and the price holds.
- Variable-speed furnaces up to 120,000 BTU
- Zoning so each floor or suite gets its own thermostat
- Rinnai tankless for households that run out of hot water
- Licensed technicians for gas and refrigeration work
- 120,000 BTULargest Midea MGH96 furnace

When a full house strains the heating and cooling
Big homes with lots of people put a different kind of load on an HVAC system. These are the problems that follow.
Grandma's room is chilly while the teenagers want it colder
One thermostat can't satisfy a main-floor suite and an upstairs full of bedrooms. Zoning with motorized dampers gives each area its own thermostat, and a variable-speed blower keeps the airflow quiet when only one zone is calling.
The bedrooms at the far end never get enough air
Long duct runs lose pressure by the time they reach the last rooms. We measure airflow at the end of each run, then resize the trunk, add a dedicated run or set up a zone so those rooms get their share.
The furnace room roars every time the heat comes on
An oversized single-stage furnace starting at full blast is loud, especially with a bedroom or suite next to it. A two-stage, variable-speed furnace starts on low fire and ramps up gently, which is far quieter.
Windows fog up and the air feels heavy
More people means more showers, more cooking and more moisture. An HRV or ERV swaps stale, damp air for fresh air, and a properly sized AC removes humidity in summer instead of short cycling.
Someone always ends up with a cold shower
A standard tank empties fast when several people shower back to back. A Rinnai RX199iN tankless heater makes hot water on demand at up to about 11.1 GPM, so the last shower runs as hot as the first.
The top floor won't cool on a July afternoon
With a full family home all day, the cooling load is higher than many builders planned for. We redo the heat-gain calculation and size the system, or add a second one, to match how the house is actually used.
Sound familiar?
Describe the problem and we'll tell you what it usually is, what it costs to fix, and whether it's worth fixing.
Pricing for big Woodbridge homes with long duct runs
Large houses need larger equipment and sometimes two systems, so the starting prices below are a floor, not a quote.
| Service | Typical price in Woodbridge |
|---|---|
| High-efficiency furnace, installed Lennox ML296V or Midea MGH96, 96% to 97% AFUE, two-stage variable-speed | From $3,300 |
| Cold-climate heat pump, installed Midea EVOX G3 or Kepler, 2 to 5 ton, rated to -30°C | From $5,500 |
| Ductless mini split, one zone Midea or Kepler wall unit with outdoor unit and line set | Written quote |
| Rinnai tankless water heater, installed RX160iN or RX199iN condensing, with venting and gas line | From $3,300 |
Installed pricing depends on size and installation requirements, and every job gets a written, guaranteed quote. Qualifying cold-climate heat pumps can bring back up to $7,500 through the Home Renovation Savings Program, and financing runs 0% for 3, 6 or 9 months on approved credit.
What Woodbridge homes ask of an HVAC system
Woodbridge is part of Vaughan, and our HVAC in Vaughan page covers the wider city. These facts are specific to Woodbridge houses.
- Homes1980s to 2000s family homes and custom builds
Sonoma Heights, Vellore Village and Elder Mills have many large homes from those decades, and Islington Woods has big custom houses.
- HouseholdsOften multi-generational
Many homes hold grandparents, parents and kids, sometimes with a separate suite. More people means more heat, moisture and hot water demand.
- UtilitiesAlectra Utilities and Enbridge Gas
Gas is the main heat in most homes here, so hybrid heat pump setups and the smaller Enbridge-home rebate come up often.
- ClimateHot inland summers, cold winters
Away from the lake, July afternoons run hot and January nights run cold. Big homes need enough capacity for both.
HVAC services in Woodbridge that keep a big house even, top to bottom
Keeping a 3,000 or 4,000 square foot house comfortable isn't only about a bigger furnace. Size alone often makes it worse. A huge single-stage unit heats the rooms near the furnace room quickly, shuts off, and leaves the far bedrooms behind.
What works is matching capacity to the house and controlling how it's delivered. We start with a Manual J load calculation, then check the duct system: the length of the runs, the size of the trunk and the number of returns on each floor. From there we choose between one variable-speed system with zoning, two systems split by floor, or a main system plus a ductless head for a room the ducts can't reach.
Noise matters too in a busy house. Variable-speed blowers and inverter-driven heat pumps spend most of their time at low speed, so you hear far less from the vents and the outdoor unit.
- Midea MGH96 furnaces from 60,000 to 120,000 BTU, two-stage and variable-speed
- Lennox ML296V and EL297V furnaces at 96% to 97% AFUE
- Zoning with separate thermostats for floors or a suite
- Cold-climate heat pumps from 2 to 5 tons
How our Woodbridge HVAC technicians plan a large system
Bigger homes get more measuring up front. It saves money later.
- 1
Hear from everyone who lives there
We ask who sleeps where, who runs warm or cold, and when the house is busiest. That tells us where zones make sense.
- 2
Measure the house and the ducts
Room-by-room load calculation, airflow at the far registers, static pressure and panel capacity.
- 3
Price one or two clear options
A guaranteed written quote with model numbers, the zone layout, a rebate estimate and financing choices.
- 4
Install, balance each zone and hand over
We commission every zone, confirm airflow in the far rooms, program the thermostats and register the warranty.
Furnace installation in Woodbridge sized for the whole family
Tell us how many floors the house has, how many people live there and which rooms cause the arguments. We'll come back with a guaranteed price on a system that fits the house, not simply the biggest unit available.
Many families here pair the new furnace with a cold-climate heat pump. The heat pump handles cooling and most of the heating, and the gas furnace covers the coldest nights. Gas-heated homes may qualify for a heat pump rebate, commonly up to $2,000, with pre-approval before installation.
- Two-stage, variable-speed furnaces for quiet, even heat
- Zoning for suites and separate floors
- Rinnai tankless for busy mornings
- 0% financing for 3, 6 or 9 months, OAC

Replaces our AC with a new heat pump in Ottawa and the whole experience was outstanding. From the first call, Dustin was incredibly responsive and communicated clearly every step of the way. He cut through all the usual sales fluff and got straight to what mattered — options, costs, timelines, and what made the most sense for our home. They addressed every concern I had, explained the details discussed my technical questions, and handled the installation quickly and professionally. The quality of the work is excellent, everything was done cleanly, and the system has been running perfectly since. Pricing was fair and transparent, and there were no surprises. It’s rare to find a company that combines speed, honesty, and solid workmanship like this. Highly recommended.
Recently got a shiny new heat pump installed. Went very well, nice unit and it works soooo quietly. These fine folks were very easy to deal with, professional and thourough. Would highly recommend.
Efficient Home Improvements truly went above and beyond. Our furnace failed on Christmas Eve in Ottawa, and their team stayed up late (3:00am) that night to replace it. Their responsiveness, professionalism, and dedication during the holidays were exceptional. The work was completed efficiently, and everything was explained clearly. It’s rare to find a company willing to sacrifice their own holiday time to ensure a customer’s home is warm and safe. I highly recommend Efficient Home improvements to anyone in need of reliable and compassionate service.
I recently had a new furnace and tankless water heater installed by this company. Excellent service by both office and technicians , I highly recommend!
The Installers were great.. Got in and got the job done..the furnace works amazing compared to the old one !!! Need a furnace..A/C water tankless system..there your guys!!!!
Had a tankless water heater installed and couldn’t be happier. The installation was quick, professional, and the system works great — endless hot water and more efficient than my old tank. Highly recommend!
Dustin and his team were really responsive and helpful in getting us a new heat pump to replace our broken AC unit. The team went above and beyond helping us through the process and answering other questions about the house we recently moved in to. I would highly recommend Efficient Home Improvements for any of your HVAC needs.

Frequently asked questions
How does an HVAC contractor in Woodbridge keep a big home even on every floor?
Size the system from a load calculation, fix long or undersized duct runs, and add zoning or a second system where one can't reach every level.
Can grandparents in a main-floor suite have their own thermostat?
Yes. Zoning or a ductless heat pump gives the suite its own thermostat, so it can run warmer without overheating the rest of the house.
What size furnace does a big Woodbridge house need?
The load calculation decides it, not the square footage. We install furnaces up to 120,000 BTU, but many big homes need less than their old oversized unit once the ducts and zoning are right.
Will a tankless water heater keep up with a big family?
A Rinnai RX199iN supplies up to about 11.1 gallons per minute, which covers several fixtures at once in most homes. Tankless pricing starts from $3,300 installed.
How quiet is a variable-speed furnace?
Much quieter than a single-stage unit, because it starts on low fire and the blower ramps up slowly instead of switching on at full speed.
Do you offer heat pump installation in Woodbridge for gas-heated homes?
Yes. We often add a cold-climate heat pump to a gas furnace in a hybrid setup, and gas-heated homes may qualify for a smaller rebate when pre-approval is in place first.
