New home owners
You moved in a few years ago and the upstairs is already uncomfortable. We check what the builder installed and fix the airflow or upgrade the equipment.
East Gwillimbury · York Region
New subdivision or farmhouse on propane, we work on both
East Gwillimbury is growing fast, and the HVAC needs on a new Queensville street look nothing like those on a rural lot a few kilometres away. We upgrade builder-grade furnaces and air conditioners in newer homes, and we install cold-climate heat pumps for rural houses heating with propane. Every quote is written, guaranteed and free of surprise extras.

New subdivisions and rural properties sit side by side here. Here's what that means for heating and cooling.
Many of these homes came with entry-level builder equipment and ducts that were never balanced after move-in day.
Village homes here often have aging furnaces, patched ductwork and plenty of room to improve.
Properties outside the villages are often off the gas line and heat with propane or oil.
Northern York Region runs colder than the south end, and open land means homes take the wind head on.
Most of our calls here come from one of these four groups.
You moved in a few years ago and the upstairs is already uncomfortable. We check what the builder installed and fix the airflow or upgrade the equipment.
A cold-climate heat pump can cut how much propane you buy each winter, and these homes may qualify for the higher rebate tier.
In Holland Landing and Mount Albert, we replace aging furnaces and ACs and tidy up the ducts while we're there.
A ductless heat pump heats and cools a finished basement or new room without overloading the builder's system.
Tell us about your house and we'll recommend the right system, with a guaranteed price and your rebate estimate.
These are the issues behind most calls we get from East Gwillimbury.
Builders often install the smallest system that passes inspection, with too few returns on the second floor. We check airflow room by room, add returns where needed and, if the equipment is undersized, quote a proper upgrade.
Single-stage builder furnaces start at full blast every time. A two-stage, variable-speed furnace like the Lennox ML296V runs on low most of the time, so it's quieter and the heat is steadier.
A cold-climate heat pump moves heat from outdoor air even well below freezing, so it can carry most of your heating. The propane furnace stays as backup for the deepest cold.
Wind off the fields pulls heat from exposed walls fast. We size from a heat-loss calculation that accounts for that exposure and add a ductless head where the ducts can't keep up.
Entry-level ACs are often sized tight. We compare the heat gain with the unit's capacity and, when it's time, replace it with a heat pump that cools in summer and heats in winter.
Our TSSA-certified gas techs check the heat exchanger, venting and repair history, then give you a straight repair or replace answer with a written price.
New subdivision lots settle for years after the house goes up, and a tilted condenser wears its compressor and fan unevenly. When we replace the unit, it goes on a proper levelled pad or a wall bracket, raised clear of the drifting snow that comes off open fields around Queensville and Sharon.
Describe the problem and we'll tell you what it usually is, what it costs to fix, and whether it's worth fixing.

A furnace that's only a few years old might still be covered by its manufacturer, and a few checks can save you from replacing something that just needs setting up properly.
If the equipment really is undersized or failing, we say so and quote the upgrade. If it isn't, you pay for a tune-up and some adjustments, and the new furnace waits until it's actually needed.

A builder system that lets you down and a propane bill you want to shrink start the same way. Tell us about the house, how it's heated and what bothers you most about it.
We'll come back with clear options and a guaranteed price, and we may beat a comparable reputable quote by up to 10% where applicable.

Rated 4.5 on Google and voted Best Company 2019, 2020 and 2021 on HomeStars.
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.

Not always. Many builder systems just need airflow fixes, added returns or balancing, and we'll tell you whether the equipment itself is undersized before suggesting a replacement.
Yes, in most cases. A cold-climate heat pump rated to -30°C can carry most of the heating season, and the propane furnace stays as backup for the deepest cold.
Homes heated by propane, oil, electricity or wood can qualify for up to $7,500 through the Home Renovation Savings Program, based on heat pump size. The pre-approval needs to come through before we install anything.
