Heat waves, cold snaps and shoulder months
HVAC demand follows the weather. A heat wave or the first freeze can double repair searches overnight, while spring and fall are quiet for repairs but ideal for tune-ups and replacement estimates. Plan budgets by season, raise caps the week a forecast turns extreme, and use Google Ads seasonality adjustments when you expect a short spike so Smart Bidding does not overreact to it.
Keep repair and replacement in separate campaigns. Repair converts on the phone within minutes; a new system is a multi-week sale with financing and home visits, and needs its own budget and conversion goals.
Update your tax credit messaging
Many HVAC ads still promise federal tax credits. According to the IRS, the Energy Efficient Home Improvement Credit, which covered heat pumps up to $2,000 a year, applies to improvements made through December 31, 2025. Ads and landing pages that suggest 2026 installs still qualify are now inaccurate. Replace them with offers you control, such as financing, maintenance plan discounts or local utility rebates you have confirmed.
Cleaning up the word "hvac"
"hvac" is also a career keyword: trade schools, EPA 608 certification, technician salaries and apprenticeships all generate large volumes. Build a negative list before launch, keep the bare term in exact match only, and review the search terms report weekly during the first month.
The data shows where buyers are: "local hvac" (1K to 10K searches, up to $80.00) and "hvac company" carry purchase intent, while "hvac cost" ($2.02 to $10.45) and "best hvac" ($2.66 to $23.44) are research clicks better served by a replacement page with price ranges.
Local Services Ads and booked-job tracking
HVAC (heating or air conditioning) is a Local Services Ads category in the US, with pay-per-lead pricing and the Google Verified badge for screened businesses. Run it alongside Search: LSA captures many emergency calls, Search lets you push replacements and maintenance plans with your own pages.
Count calls over 60 seconds, capture the GCLID on web forms and upload sold systems as offline conversions with their value. A maintenance plan customer is worth years of revenue, so value those conversions higher than a single repair call.
