Low-maintenance systems that hold up to tenants and long winters
Kitchener-Waterloo HVAC for landlords and families comes down to two things: equipment that rarely breaks, and repairs that don't drag on. We install and fix furnaces, air conditioners and cold-climate heat pumps in student rentals near the universities and family homes in Doon, Beechwood and beyond. Every job starts with a written price that won't change.
Voted Best Company 2019 to 2021 · Authorized Midea, Lennox, Kepler & Rinnai dealer, plus Goodman · 20+ years








Rentals, older central homes and newer subdivisions all sit within a few kilometres of each other here. Here's what shapes the work.
Older houses in Downtown Kitchener and Uptown Waterloo, student rentals near the universities, and 1990s to 2010s homes in Laurelwood and Beechwood.
Hydro comes from Enova Power. Natural gas in Kitchener comes from Kitchener Utilities, and Enbridge Gas serves much of the surrounding area.
Away from the lake, January runs colder than the lakeshore and July gets properly hot, so heating and cooling both work hard.
Electric, oil or propane heated homes may reach up to $7,500. For gas-heated homes, eligibility depends on the program terms and your utility, and we confirm it before installation.
Rental owners and families call about different things, but the fixes come from the same place: find the cause, then fix it once.
We take emergency calls evenings, weekends and holidays. With your OK we book the visit with the tenant directly, and you get the diagnosis and a written price before any repair starts.
Repeat flame sensor or pressure switch calls usually point to a cause upstream: a clogged filter, a blocked condensate line or a venting issue. We fix the cause so you stop paying for the same visit.
We can fit a deeper media filter cabinet that lasts several months between changes, and book your annual tune-up when the unit turns over in spring.
One furnace and one thermostat can't please two households. A ductless head in the lower unit gives that tenant their own heat and cooling without rebalancing the whole house.
A smart thermostat with setpoint limits keeps the system in a sensible range and lets you see problems from your phone. Qualifying smart thermostats can earn a $100 rebate.
Twenty-year-old builder units often need more repairs each year. We price the repair and the replacement side by side, including two-stage, variable-speed Lennox and Midea furnaces, so the choice is clear.
A student house near the universities often has bedrooms on three floors sharing a single control in the hallway. A ductless head in the hottest or coldest rooms gives those tenants their own setting, and a smart thermostat with locked limits keeps the main system in a sensible range. Both cost less than the calls you're fielding now.
Describe the problem and we'll tell you what it usually is, what it costs to fix, and whether it's worth fixing.
Owners want a number they can approve from their phone. Repairs are quoted after the diagnosis, installs start at the figures below, and nothing changes once you sign.

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.

A properly sized high-efficiency furnace or cold-climate heat pump with a deep media filter and a yearly tune-up is about as low-maintenance as it gets. Good installation matters more than any single brand.
Possibly. For gas-heated homes, eligibility depends on the program terms and your utility, and we confirm it before installation. Homes heated by electricity, oil or propane may qualify for up to $7,500.
Yes. We take emergency calls evenings, weekends and holidays. Call 1-647-694-5845 and we'll give you an honest estimate of when a technician can arrive.
Pick one that puts prices in writing, explains the cause of each repair and sends you records you can keep. That protects you with tenants, insurers and future buyers.
Often, yes. A cold-climate heat pump replaces your central air and covers most of the heating season, and a hybrid setup keeps the gas furnace for the coldest days.
Furnace repair in Kitchener-Waterloo is quoted after the diagnosis, because the price depends on the part: an ignitor, a flame sensor and a control board all cost different amounts. You see the written price before we fix anything. If replacement makes more sense, a new high-efficiency furnace starts from $3,300 installed, and installed pricing depends on size and installation requirements.
