Grimsby HVAC Services for Lakeside Condos, Townhomes and Older Houses
Small spaces, lake humidity and escarpment wind, all in one town
HVAC in Grimsby has to fit a wide range of homes: townhomes and condos along the lake, older houses in town and rural places up on the escarpment. We install compact heat pumps, ductless systems and air conditioners that can handle a humid lake summer, and we repair furnaces and AC across town. Before any work starts, you'll have a guaranteed price on paper.
- Compact outdoor units for small patios and tight side yards
- Ductless options for condos and older homes without ducts
- Cooling sized to pull lake humidity out of the air
- Placement plans you can hand to your condo board

Heating and cooling in Grimsby at a glance
Grimsby sits between Lake Ontario and the escarpment, and that shapes almost every system we recommend here.
- Housing mixLakeside condos to escarpment homes
Newer townhomes and condos near the water, older houses downtown and rural properties up the hill each need a different setup.
- UtilitiesGrimsby Power for hydro, Enbridge for gas
We look at your Grimsby Power rates and Enbridge gas use before suggesting how much heating a heat pump should carry.
- ClimateMuggy summers, gusty winters
The lake keeps winters milder than inland, but summer air is heavy with moisture and the escarpment funnels wind through town.
- HoursSeven days a week
Book Monday to Saturday between 8 am and 8 pm, or Sunday between 10 am and 5 pm. Emergencies are handled evenings, weekends and holidays.
Grimsby HVAC problems, from the beach to the mountain
These are the issues that come up most in a town with this many home types. Every one of them has a sensible fix.
Your townhome has almost no room for an outdoor unit
Lakeside townhomes often leave a small patio and a narrow strip beside the wall. We use compact inverter condensers, wall brackets and short line set routes, and we plan the spot before install day so nothing blocks a door or a neighbour's window.
The house feels clammy all July even with the AC on
When the AC is too big, it drops the temperature in minutes and stops long before the coil has wrung much water out of the air. A properly sized variable-speed system runs longer at low speed, which dries the air as well as cooling it.
Your condo unit has electric baseboards and no AC
A ductless heat pump adds quiet cooling and much cheaper heat than baseboards on mild days. Electrically heated homes can also qualify for the top rebate tier, up to $7,500 based on size.
An older house downtown has hot-water heat and nothing for summer
We leave the boiler where it is and add ductless heads to the rooms that matter, so you get cooling in summer and heat pump heating in spring and fall.
Escarpment wind finds every gap in your rural home
Exposed homes up the hill lose heat faster. Sizing comes from a Manual J heat-loss calculation, the equipment is rated to -30°C, and the outdoor unit sits on a stand sheltered from the strongest gusts. If you heat with propane or oil, a heat pump may also qualify for the higher rebate.
Water shows up on the floor of the condo utility closet every August
Humid lake air means the indoor coil pulls out litres of water on a hot day, and a clogged drain line or a tired condensate pump overflows. We clear and re-slope the drain, replace a weak pump, and add a float switch that shuts the system off before water reaches the floor or the unit below.

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
Can I put a heat pump on a small Grimsby townhome patio?
Usually, yes. Compact inverter condensers and wall brackets fit many small patios and side strips, and we plan placement around doors, windows and neighbours before booking.
Do condo owners in Grimsby need board approval for ductless?
Most condo corporations require approval before any outdoor equipment or wall opening. We give you a placement plan and equipment details to submit with your request.
The AC is on, so why does my Grimsby home still feel sticky?
The AC is probably oversized or running too few long cycles to remove moisture. A correctly sized variable-speed system runs longer at low speed and dries the air as it cools.
Is heat pump installation in Grimsby priced differently for condos and houses?
Yes, because the equipment differs: a ducted cold-climate heat pump in a house starts at $5,500 installed, while condo and townhome ductless setups are priced once we've seen the space. Installed pricing depends on size and installation requirements, and the quote you accept is the price you pay.
Can I book AC repair in Grimsby on a Saturday or Sunday?
Yes. We're open Saturdays and Sundays and take emergency calls evenings, weekends and holidays. Call 1-647-694-5845 to book.
