Editorial Review
Our Take on SunnySide Heating and Air Conditioning
SunnySide has a clear specialty in heritage homes, and its 4.9 rating from 195 Google reviews, read September 16, 2026, is full of stories about difficult installs done neatly. Handling EV chargers and panel upgrades in-house is a practical bonus for heat pump projects. Ask for the warranty terms and TSSA number, since neither is published.

About SunnySide Heating and Air Conditioning
Chester Hill Road runs along the top of the Don Valley near Broadview Avenue, surrounded by the kind of tall, narrow Victorian and Edwardian houses that were never built for central air. SunnySide Heating and Air Conditioning works from there, and its website makes older homes the core of its pitch. The company says it started with one truck, has served East York and Toronto for more than 25 years, and is still run by its owner.
Cooling an old house is the real skill here. SunnySide lists SpacePak high-velocity systems, which use small flexible tubes that can be snaked through walls and closets instead of full ductwork, plus ductless heat pumps. On the heating side it handles furnaces, boilers and radiator work, and it also installs water heaters, water filtration, humidifiers and air filtration. More unusually, it offers EV charger installation and electrical panel upgrades, which often come up when a home switches to heat pumps. Navien, Aprilaire, Honeywell and SpacePak are among the brands on its site.
The reviews read like a portfolio of old-house jobs. One describes two outdoor condensers and six indoor units fitted into a Parkdale house more than 120 years old, finished on time and for less than other quotes. Another homeowner had four wall-mounted AC units installed after bad experiences with other contractors and was relieved by how tidy the crew kept things. Several reviewers use words like careful, clean and white-glove, and one noted that the installers clearly cared how the finished equipment looked.
Posted hours are 7 AM to 7 PM every day, and the website advertises 24-hour emergency support 365 days a year. It mentions strong warranties but does not spell out the terms, so ask for them. No TSSA number is published on the main pages either.
Who it suits: owners of century homes and heritage houses in Riverdale, Leslieville, the Danforth, Parkdale and similar areas who want air conditioning or a heat pump without tearing open walls. It is also good for anyone who needs the HVAC and electrical upgrade handled together. Who it suits less well: people with newer suburban homes who just need a standard furnace swap and are pricing only on cost.
Before booking, ask how the high-velocity or ductless layout will be routed, who handles patching and painting, and what the written warranty covers.

SunnySide Heating and Air Conditioning FAQs
Can SunnySide add air conditioning to an old house with no ducts?
Yes. Older homes are its specialty. It installs SpacePak high-velocity systems, which run small flexible tubes through walls and closets, as well as ductless heat pumps. Reviews describe multi-unit installs in houses more than 120 years old.
Does SunnySide do electrical panel upgrades?
Yes. SunnySide installs EV chargers and upgrades electrical panels, which often comes up when a house moves to a heat pump and needs more capacity.
What are SunnySide's hours?
Posted hours are 7 AM to 7 PM every day, and the website advertises 24-hour emergency support 365 days a year. Ask about after-hours charges when you call.
Is SunnySide Heating and Air Conditioning licensed and insured?
We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.

Toronto, Concord, East York. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does SunnySide Heating and Air Conditioning offer emergency service?
Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.
What warranty do they offer?
Work backed by strong warranties and long-term support. There are usually two warranties on a job: the manufacturer covers materials, the contractor covers workmanship. Get both in writing and check whether the workmanship coverage transfers if you sell.
