Editorial Review
Our Take on Convertible Heating and Air Conditioning
A 1967 start date and a 5 rating from 97 Google reviews, read on September 27, 2026, is a combination worth a phone call, particularly if you want the same company for the install and the annual service. The round-the-clock published hours and the regional phone lines suggest a real dispatch operation rather than a single van. Just pin down the after-hours call-out charge and the labour warranty length in writing before you sign anything.
Best for: GTA homeowners wanting one long-established firm for both emergency repairs and full system replacement
What We Like
- Rated 5 from 97 Google reviews, read on September 27, 2026
- Trading since 1967 according to its own website, family run
- Published hours show 24 hours a day, seven days a week
- Covers furnaces, AC, heat pumps, water heaters and air quality under one roof
- Separate regional phone lines for Mississauga, Brampton, Toronto, Halton, Durham and Niagara
- Mississauga head office with financing and rebate assistance advertised
Things to Consider
- 97 reviews is a modest count next to the largest GTA HVAC advertisers
- Licensing, insurance and WSIB membership are company claims, so ask for TSSA credentials on site
- No pricing is published, so after-hours call-out rates need confirming by phone
- A very wide service area means travel time may vary by region

About Convertible Heating and Air Conditioning
Six decades in one trade leaves a mark on how a company works, and Convertible Heating and Air Conditioning presents itself as exactly that sort of business: family owned, started in 1967, still headquartered in Mississauga at Blundell Road in the industrial pocket south of the QEW. The work spans the full residential range. Furnace and boiler repair and replacement, central air conditioning, cold-climate heat pumps, tankless and tank water heaters, plus indoor air quality assessments covering humidifiers, filtration and ventilation. Preventative maintenance is offered as a service line in its own right rather than an afterthought bundled into a sales call.
Who it suits is fairly clear. Homeowners across Mississauga, Brampton, Toronto, Halton, Durham and the Niagara region who need a contractor that can handle both the emergency and the eventual replacement, and who would rather deal with a single company through the life of the equipment. The website lists separate local numbers for each region alongside the toll-free line, which suggests dispatch is organised geographically rather than everything routing through one Mississauga depot. If you want a rock-bottom price on a builder-grade furnace from a one-van operator, this is probably not the cheapest quote you will collect. Established companies with staff, a warehouse and a service department price accordingly.
The Mississauga housing stock explains a lot about the calls. Port Credit and Lorne Park hold older homes where the original ductwork was sized for a mid-efficiency furnace and the chimney liner assumptions no longer hold once you move to a condensing unit and a side-wall vent. Meadowvale, Erin Mills and Churchill Meadows are full of eighties through two-thousands subdivisions now hitting the point where the first or second air conditioner is done. Newer builds along Hurontario and in the city centre often came with equipment chosen on cost, and owners replacing it find the outdoor clearances tight. Any of those situations changes the job, so ask how the quote accounts for venting, condensate drainage and electrical capacity before you compare numbers.
Ontario's rebate landscape is worth raising on the call. The company advertises financing and rebates as part of its offering, and heat pump incentives in this province have shifted repeatedly in recent years, so the practical question is which programs are live at the time of your quote and whether the contractor handles the paperwork or leaves it to you. Ask too about the equipment brands carried, because warranty terms, parts availability and the length of the labour coverage differ meaningfully between manufacturers. A ten-year parts warranty is common; labour coverage is where quotes diverge.
Day to day, the process described on the website is straightforward: call, talk through the problem and pricing with no obligation, then book. Published hours run 24 hours across all seven days, which is the useful detail for anyone whose furnace fails on a cold Sunday. Worth confirming when you call whether that means a technician is dispatched overnight or a coordinator takes the message, and what the after-hours call-out charge is. Emergency pricing in the GTA typically carries a premium, and it is better to know the number before the van arrives than after.
The company states it is licensed and insured, a WSIB member, and that its technicians are factory trained. Those are its own claims rather than anything verified here, and in Ontario any gas work should be done by a TSSA-certified gas technician, so it is reasonable to ask for the ticket number on site. The profile also links to a Better Business Bureau listing, which is a place to read complaint history if you want a second source beyond Google.
On reputation, the Google Business Profile shows a rating of 5 from 97 reviews, read on September 27, 2026. A perfect average across that many reviews is unusual and speaks well of the service department, though the count is smaller than some high-volume GTA competitors who have accumulated thousands. Read a handful for the specifics rather than the score.
Against the alternatives, Convertible Heating and Air Conditioning sits between the large rental and subscription HVAC companies that dominate GTA advertising and the small independent installers. Longevity, a physical Mississauga base and a broad service area are the case for it. Get at least two written quotes, confirm what the after-hours rate is, and ask what happens to the warranty if you sell the house.

Convertible Heating and Air Conditioning FAQs
Does Convertible Air really answer the phone at night?
Published hours on its Google profile show it open 24 hours a day, seven days a week, and the website gives a toll-free emergency number at 1 (800) 423-0969. What is not stated is whether a technician is dispatched overnight or a coordinator books you for the morning, so ask when you call, and ask what the after-hours rate is.
What areas does the company cover?
Mississauga and Brampton, Greater Toronto, Hamilton and Halton, Durham Region and the Niagara Region, each with its own published local phone line. The head office is at 1321 Blundell Rd, Units 10 and 11, in Mississauga.
How is it rated?
Its Google Business Profile shows a rating of 5 from 97 reviews, read on September 27, 2026. That is an unusually clean average, though the review count is smaller than some of the larger GTA HVAC chains, so it is worth reading a few for detail on how repairs and installs actually went.
Can they help with heat pump rebates in Ontario?
The website lists financing and rebates as part of what it offers, so yes in principle. Ontario incentive programs change often, so ask which ones are open at the time of your quote, how much they are worth against your specific equipment, and whether the company submits the paperwork on your behalf.
Is convertible heating and air conditioning a good fit for an older Port Credit or Lorne Park house?
It should be, given the company installs across the full range of residential systems, but older homes bring specific complications worth raising up front. Chimney venting, duct sizing and condensate drainage all change when a mid-efficiency furnace is swapped for a condensing one, and those details belong in the written quote.
What should I ask before booking?
Get the after-hours call-out charge, the labour warranty length, the brands carried and whether the technician attending holds a TSSA gas ticket. The company states it is licensed, insured and a WSIB member, and it links to a Better Business Bureau profile, but confirming credentials on site is standard practice for any gas work in Ontario.
How long has the business been operating?
Since 1967, according to its own website, which also describes the business as family run and locally owned. That would make it one of the longer-established HVAC contractors working out of Mississauga.
Is Convertible 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.
What areas does Convertible Heating and Air Conditioning serve?
Toronto, Mississauga. 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 Convertible Heating and Air Conditioning offer emergency service?
Emergency availability is not listed for this company. If you need an urgent call-out, check the ranking for companies that do list it.
What warranty do they offer?
Warranty terms are not on file. Ask for them in writing before work starts.
How was this profile built?
