How much should an HVAC company spend on marketing?

How much you need depends heavily on whether you're chasing emergency repairs, full replacements, or both. A one-crew company keeping the schedule filled can start lean: Google Ads near the $600 management floor plus enough spend to show up for "no heat repair" or "AC not cooling" searches without disappearing during off-peak weeks.

A company with a couple of install crews and a maintenance-plan base usually lands in a growth band of $2,500 to $5,000 a month, splitting spend between always-on repair campaigns and an SEO program past the 10-page minimum that builds pages for furnace repair, AC installation, and each service area, so fewer of those searches need to be bought by the click every month.

A larger regional HVAC company, or one pushing full-home replacement and financed installs hard, often needs $5,500 or more a month, since covering multiple crews across a wide territory during both a heat wave and a cold snap takes real ad budget rather than just a bigger management fee.

Google Ads management is 10% of your spend, floored at $600 CAD or $450 USD a month, with nothing added on top of the media dollars. For HVAC, this is usually the fastest way to catch a household with no heat or no air conditioning right now, since that caller is booking with whoever answers first, not researching for a week.

SEO is $50 CAD or $38 USD per page starting at 10 pages a month. For an HVAC company, that typically covers pages for furnace repair, AC installation, ductless systems, and maintenance plans, plus location pages for each town served, built around phrases like "furnace installation cost" or "AC repair near me." It builds slower than ads but eventually produces calls you're not paying per click for.

A website is a separate one-time cost, from $1,500 to $20,000 and up. For most HVAC companies, the biggest cost driver is whether the site needs a maintenance-plan signup flow and financing details for a full system replacement, or whether a simple, fast site built around click-to-call and clear service pages is enough for now.

LocaliQ and WordStream's 2026 Search Advertising Benchmarks report groups HVAC under Home & Home Improvement, averaging a $90.92 cost per lead and an 8.05% conversion rate on Google Ads. That number spans everything in the category across every market studied, so it works as a reference range, not a promise for your specific city.

The practical use is comparing it against what a proposal implies. If the ad spend in a quote, once the management fee is removed, works out to well above roughly $91 per lead with no clear explanation, ask what's driving it, a highly competitive market during peak season, a broad set of keywords, or an underperforming account. A well-targeted emergency-repair campaign in a smaller market can beat that number; a broad campaign competing against national HVAC brands during a heat wave can run above it.

Seasonal swings matter more here than in almost any other trade. Demand spikes hard during a heat wave or a cold snap, and companies that flex ad spend up during those windows generally get more service calls per dollar than ones running the exact same budget every month regardless of the weather outside.

Whether replacement decisions get made in the shoulder seasons is the other big factor. Spring and fall, when systems aren't under maximum stress, are often when homeowners decide to replace an aging unit rather than keep patching it, so a company chasing that higher-ticket work usually shifts more budget toward SEO and content in those windows.

Who else competes for your calls also shapes the number. Home warranty companies and new-home builders often route service work to whichever HVAC company they've partnered with, which is a referral channel worth building alongside paid search, not a replacement for it. There's no setup fee, plans run month to month, and the first 30 days are covered by a guarantee: if you're not satisfied, you don't pay.
