North York HVAC Services for New Custom Homes and the Bungalows Beside Them
Same street, two very different houses
On plenty of North York streets, a 1950s bungalow sits right next to a 4,000 square foot rebuild, and the two need completely different HVAC. We size heating and cooling for large custom homes from a proper load calculation, zone them so every floor stays comfortable, and replace undersized original systems in the older houses next door. You get a guaranteed written price before any work begins.
- Room-by-room Manual J sizing, never a square-foot guess
- Zoning and two-system designs for large rebuilds
- Upgrades for undersized original furnaces and ACs
- Permits, warranty registration and rebate paperwork handled

Heating and cooling in North York's big rebuilds starts with the right size
A new custom home in Willowdale or York Mills is a very different building from the bungalow it replaced. Tighter walls, better windows, high ceilings, a finished lower level and often a wall of glass across the back. Heat loss and heat gain don't scale neatly with floor area, so a contractor who sizes by square footage usually gets it wrong.
Oversizing is the most common mistake we find. A furnace or AC that's too big runs in short bursts, leaves rooms uneven and does a poor job of pulling humidity out on a sticky July night. North York sits inland, away from the lake breeze, so summer cooling and dehumidifying matter as much as winter heat here.
We work from a Manual J load calculation, room by room, using the drawings or the finished house. Then we choose between one variable-speed system with zoning, two separate systems, or a main system plus ductless for a loft or a lower-level media room. Still at the planning stage? Bring us in early so the duct chases and mechanical room are big enough. For semis, laneway lots and the rest of the city, our page on HVAC in Toronto covers those jobs.

- Zone thermostats placed where they read real room conditions
- A second system for upper floors when one can't serve the whole house
Rebuild or original bungalow: the calls a North York HVAC technician gets
The houses couldn't be more different, but the problems fall into a few clear patterns.
The house is only two years old and the floors are still uneven
That usually points to one large system with no zoning, or ducts that were never balanced after the build. We measure airflow at each register, set the dampers and, where it's needed, add zoning so each floor gets its own thermostat.
The AC short cycles and the air still feels damp
An oversized air conditioner drops the temperature fast and shuts off before it removes much moisture. We compare the load with the equipment, and a right-sized or variable-speed system runs longer at low speed and actually dries the air.
The original furnace can't keep up since the renovation
Finishing the basement, adding a sunroom or opening up walls changes the load, but the furnace stayed the same. We recalculate and size a new system for the house you live in now.
Bungalow ducts are too small for central air
Many post-war homes in Bathurst Manor and Don Mills had ducts sized for heat only. We test static pressure and tell you plainly whether to upsize a few runs, add a return or go with a high-wall ductless head instead.
Two systems in the new house seem to fight each other
When the upper and lower systems share an open stairwell, one ends up doing the other's job. We check thermostat placement, set sensible schedules and balance the two so they stop overlapping.
The lower-level gym or media room is always stuffy
Rooms with lots of people and equipment need their own airflow. A ductless head or a dedicated zone handles the extra heat without overcooling the rest of the floor.

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 do you size HVAC for a new custom home in North York?
We size it from a room-by-room Manual J load calculation based on the drawings or the finished house, not from square footage. That tells us whether one zoned system, two systems or a mix with ductless is right.
Why does my new North York home have uneven temperatures?
Usually it's one large system without zoning, unbalanced ducts or a thermostat in the wrong spot. Balancing the airflow and adding zoning fixes most cases.
Is the original furnace in my bungalow too small now?
It may be if you've finished the basement or added space since it went in. A fresh load calculation shows whether the furnace and AC still match the house.
When does a North York rebuild need two systems instead of one?
When the load calculation shows one system can't move enough air to every floor without oversized ducts or noisy airflow. Many large rebuilds use two systems, or one zoned system plus ductless for the hardest rooms.
What do HVAC services in North York cost for a furnace replacement?
A high-efficiency furnace runs from $3,300 installed, and a cold-climate heat pump from $5,500. Final pricing depends on size and installation requirements, and your written quote is guaranteed.
Can an HVAC contractor in North York help before my rebuild is finished?
Yes. Bringing us in at the drawing stage lets us plan duct routes, the mechanical room and panel capacity before the walls close up.
