Furnace season and AC season: a pre-season visibility checklist for HVAC companies

Why timing matters

Most GTA HVAC companies know when the phones go crazy: the first real cold snap, and the first heat wave. The mistake is updating the website and profile once the rush has started. By then you're too busy, and the changes may not have been picked up yet.

Google says that recrawling a page "can take anywhere from several days to several months" depending on how often its systems decide a page needs refreshing (AI features and your website). ChatGPT and Gemini read the same web and the same listings. So a furnace page updated in the first week of a cold snap may still show last spring's version to an AI tool.

The City of Toronto's bylaw sets useful anchor dates. Landlords must keep rental units at 21°C or more from October 1 to May 15, and where air conditioning is provided, run it from June 1 to September 30 to keep units at 26°C or below. Plan to finish each checklist a few weeks before those dates.

For the month-by-month view of GTA demand and rebates, see our Ontario HVAC calendar. This guide is the checklist you run before each season starts.

Before furnace season (aim for early September)

Your Google Business Profile

• Set your winter hours. Google's guidelines let you use your current seasonal hours as your regular hours. If you extend hours or add weekend coverage in winter, change them now, and put a reminder in your calendar to change them back in spring. If you add night coverage, our guide to 24/7 and emergency claims covers how to describe it honestly.
• Set holiday hours now. Google's special hours page suggests confirming hours for official holidays even if they don't change. Ontario's public holidays in heating season include Thanksgiving, Christmas Day, Boxing Day, New Year's Day, Family Day and Good Friday. Set them all in one sitting.
• Check your services list has your heating jobs: furnace repair, furnace installation, boiler service, heat pump installation, humidifiers. Our categories and services guide explains why the list matters for reviews.
• Post a dated update. Google's posts help page says posts show on your profile in Search and Maps, can be scheduled ahead, and that posts older than six months are archived unless a date range is set. A plain post such as "Booking furnace tune-ups for October and November in Vaughan, Richmond Hill and Markham" tells a reader you're current.
• Add recent photos. A technician at a real furnace install this year, not a stock image.

Your website

• Bring heating to the front. Put furnace repair and heating at the top of your homepage and menu. If summer moved AC to the front, swap it back.
• Update your furnace pages. Check prices or price ranges, brands, rebate notes and the "last updated" date. Only change the date if you changed the content.
• Check rebate wording. Programs change. The Home Renovation Savings program is the current Enbridge and Save on Energy program; read its current terms before you mention specific amounts.
• Make your winter availability plain. If you take no-heat calls on weekends or at night in winter, say so in a sentence near the top of the page.

Your team

• Brief technicians on review asks. Heating demand in the GTA peaks in winter, as our calendar shows, so that's when the most review asks can go out. BrightLocal's 2026 consumer survey found 74% of consumers care about reviews written in the last three months, so a steady flow through winter keeps your profile current for spring. Our guide on asking without being pushy has the scripts.
• Tell whoever answers the phone your winter hours, since Google may call to confirm them.

Before AC season (aim for mid-April)

The same structure, flipped.

Your Google Business Profile

• Change to your summer hours and remove any winter-only night coverage.
• Set holiday hours for Victoria Day, Canada Day and Labour Day, which are on Ontario's public holiday list, and for the August Civic Holiday if your hours change for it.
• Check your services list has cooling jobs: AC repair, central air installation, ductless mini-splits, heat pumps.
• Post a dated update about AC tune-ups or installs, with the areas you're booking in.

Your website

• Bring cooling to the front of your homepage and menu.
• Update your AC and heat pump pages: brands, ranges, rebate notes, date.
• Add the questions people ask in spring. "Should I replace my AC with a heat pump?" and "Is my AC big enough?" come up often. Our guide on the questions service pages should answer shows how to collect them.
• Mention landlord rules if you serve rental buildings. Toronto's bylaw requires air conditioning, where provided, to be run from June 1 to September 30.

Your team

• Re-brief on review asks for AC calls. The customers you served in winter may already have reviewed you; summer brings a new group.

Both seasons: check what AI says about you

At the start of each season, ask the questions homeowners ask, in their words, with your city:

• "Who can fix a furnace that won't turn on in Mississauga?"
• "Best company to install central air in Oakville"
• "Heat pump installers near Pickering"

Run them in ChatGPT, Gemini and Google. Note who's named and which pages are linked. Do the same a few weeks into the season. If the answers still describe your summer hours in November, find the source: an old directory listing, a stale page, or a profile you forgot to update. Our guide on checking whether AI recommends you explains how to test properly.

Put it in the calendar

The simplest version of all this is two calendar entries a year:

• First week of September: run the furnace checklist.
• Mid-April: run the AC checklist.

Add a third for the first week of December to confirm your holiday hours. Each checklist takes an afternoon. Doing it early is what makes it count.
