Whitby · Port Whitby to Brooklin
A lakeside heritage home and a Brooklin new build need different answers
Good HVAC in Whitby starts with the house, not the brochure. A brick home near Port Whitby and a new build in Brooklin need different systems, and we size, install and repair furnaces, heat pumps and air conditioners for both. You see a guaranteed written price before any work starts.





South Whitby has heritage homes downtown and in Port Whitby, plus plenty of 1980s to 2000s family houses. The lake takes the edge off winter here. The trouble is usually inside the walls: small or missing ducts, plaster you don't want to open, and older equipment that was never sized properly.
North Whitby is another story. Brooklin and Taunton North are full of newer homes with tight construction and decent ductwork, but they sit on open, windier ground that runs colder in January. These homes suit a ducted cold-climate heat pump, often with a furnace or electric air handler behind it.
In between sit the 1980s to 2000s homes in Rolling Acres, Blue Grass Meadows and Pringle Creek. They usually have workable ducts and an original or second-generation furnace, which makes them the simplest jobs: a two-stage furnace, a matched heat pump or AC, and a proper balance of the registers.
So we don't walk in with a favourite product. We measure, run the heat-loss numbers and look at the ducts first. Then we recommend the system that fits the house you actually live in.

Each link explains the equipment, the options and what the work involves.
A lot of comfort problems come from the wrong equipment for the house. These are the ones we see most in Whitby.
Running new ducts through finished plaster is messy and costly. Ductless heads mount on the wall, connect through a small hole, and give you cooling in summer plus efficient heat in spring and fall.
Tight new homes trap moisture. We check the HRV or ERV, clean and balance it, or add one if it's missing, and set humidity so the glass stays clear.
Open lots lose more heat on windy days. We confirm the heat loss for that room, balance the airflow and size the furnace or heat pump for the colder design temperature up there.
Size by square footage alone and you end up with short cycling or cold rooms. We use a Manual J calculation and explain why the size we picked suits your walls, windows and ducts.
Older houses leak warm air and pull in dry outside air. A whole-home humidifier on the furnace, set to match the outdoor temperature, brings the moisture back without fogging the windows.
Stretching old ductwork rarely works well. A single-zone or multi-zone ductless system gives that space its own heating and cooling and its own controls.
Sharing one thermostat between two households never ends well. A ductless head in the apartment, on its own outdoor unit or as a zone of a multi-zone system, gives the tenant their own remote and keeps your upstairs setting untouched. It also means a repair on one system doesn't leave both floors without heat.
Describe the problem and we'll tell you what it usually is, what it costs to fix, and whether it's worth fixing.

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!
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.

It depends on the ducts. If the house has sound ductwork, a high-efficiency furnace or hybrid heat pump works well, and if it has radiators or no ducts, ductless heads are usually the cleanest choice.
Many newer homes already have one, and it needs regular cleaning and balancing to work properly. If yours is missing or not doing its job, foggy windows and stale air are the usual clues.
Yes, in most cases. Newer homes there usually have tight construction and decent ducts, which is exactly what a ducted cold-climate heat pump needs to run well.
Yes. Ductless mini splits add cooling to homes with hot-water radiators without new ductwork, and they also supply efficient heat in spring and fall.
Usually because some size by square footage and some do a proper heat-loss calculation. Ask each company to show the heat-loss number behind its recommendation.
Yes. Furnace installation starts from $3,300, and you can spread it out with 0% interest for 3, 6 or 9 months or a loan from 2.99% OAC.
