We install high-efficiency air conditioners and cold-climate heat pumps that cool for months and heat efficiently through the milder winters, from Walkerville to South Windsor. You get a guaranteed, written price and help with any rebate you qualify for.

Air conditioning in Windsor: why efficiency ratings matter more here
An air conditioner in Windsor runs more hours each year than the same unit in Barrie or Sudbury. That makes its efficiency rating worth real money. SEER2 measures cooling efficiency over a season: the higher the number, the less hydro each hour of cooling uses. Across many long summers, a few points of SEER2 add up.
A heat pump takes the same idea further. It cools exactly like an AC, then runs in reverse to heat your home, and its heating efficiency is rated as HSPF2. Because winters here are milder than most of Ontario's, a cold-climate heat pump can handle a large share of the heating here, with a gas furnace or electric backup for the coldest days.
Comfort counts too. Variable-speed and inverter equipment runs at low speed for long stretches, which draws moisture out of humid air. That is what takes the clammy feeling out of a July evening.

Problems our Windsor HVAC technician fixes in peak season
Long cooling seasons are hard on equipment. These are the calls that come in once the heat settles in.
The AC can't keep up on the hottest afternoons
A dirty outdoor coil, a low refrigerant charge or a unit too small for the house are the usual causes. We test, clean and check the charge, then tell you honestly if the system is undersized.
Your hydro bill jumps every July and August
An older AC with a low efficiency rating draws far more power than a modern one. We show you the SEER2 difference and what it could mean across a typical summer here.
It's cold inside but the air still feels heavy
A single-speed unit that's too large chills the air fast and shuts off before removing the moisture. Variable-speed equipment and the right blower settings fix the feeling, not just the temperature.
The suction line by the condenser grows a coat of ice
That usually points to low airflow from a clogged filter or dirty indoor coil, or to a refrigerant leak. Our licensed refrigeration techs find which one it is and fix it.
Your R-22 air conditioner needs topping up again
R-22 has been phased out in Canada, so topping it up gets harder and pricier every year. A new AC or heat pump on modern refrigerant is usually the better spend.
Your furnace barely runs, yet you still pay for gas all winter
With mild winters, a heat pump can do much of the heating. A hybrid setup keeps the furnace for cold snaps and lets the heat pump handle everything else.
The second floor of your Walkerville home runs several degrees warmer all summer
Old brick soaks up sun all day and gives it back at night, and the upstairs ducts in these houses are often small or missing. We check return air first, since a starved return is the usual culprit. If the ducts can't carry enough cool air, a ductless head in the upstairs hall or the main bedroom gives that floor its own cooling without touching the plaster.
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.

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.

Frequently asked questions
Is a heat pump a good choice for Windsor's climate?
Yes, for many homes. It cools like central air through the long summer, and the milder winters here let it handle a large share of the heating.
What SEER2 rating should I look for in Windsor?
Higher is better when your AC runs as much as it does here. We compare a few SEER2 levels in your quote so you can weigh the upfront cost against hydro savings.
What's the starting cost of heat pump installation in Windsor?
Before rebates, our cold-climate heat pumps begin at $5,500 installed. The final price depends on size and installation requirements, and it's guaranteed in writing.
My AC quit on a Saturday. Is AC repair in Windsor possible before Monday?
Yes. Our emergency line covers evenings, weekends and holidays. Call 1-647-694-5845 and we'll be straight with you about when a technician can get there.
Should I replace an air conditioner that uses R-22?
In most cases, yes. R-22 has been phased out in Canada, so any repair that needs a recharge keeps getting more expensive.
Are Tecumseh and LaSalle covered as well?
Yes. We book visits across Windsor, Tecumseh, LaSalle and nearby Essex County, working from our Stouffville office.
Does a heat pump dehumidify better than a regular AC in Windsor?
An inverter heat pump usually does, because it can run at low speed for long stretches instead of cycling on and off. Longer run time means more air passes over a cold coil and more moisture drains away. A single-speed AC sized correctly can still do a fair job, but an oversized one won't.
