How much should an HVAC company actually spend on Meta ads?

Every HVAC owner we talk to asks the budget question first. It's the wrong question — but it's the one that decides whether you ship a campaign or sit on your hands for another season. So let's answer it properly.

Start with the install, not the ad spend

Pick a number you'd be happy paying to book one install. Not a lead. A signed, scheduled, deposit-paid install. For most CT HVAC operators that number is somewhere between $400 and $2,000 depending on average ticket and close rate.

Multiply that number by the installs you want booked per month. That's your ad budget floor — not your ceiling.

What different spend levels actually buy you

$1,000–$1,500 / month

Realistic floor. Enough for one platform — usually Meta — running tune-up and seasonal offers. Expect 8–15 booked appointments per month, maybe 2–4 converting to installs depending on close skill.

$3,000–$4,000 / month

Where most growth-mode HVAC shops should sit. Meta lead gen + Google LSAs running in parallel. Expect 25–40 booked appointments, 6–12 installs, plus steady service work.

$8,000+ / month

Multi-county coverage, dedicated install funnel, retargeting layer, branded video creative. Expect 60–100 appointments and 15–25 installs — but you need crew capacity to back it up.

The hidden cost nobody quotes

Whatever your ad budget is, your missed-call rate is doing more damage. If 30% of after-hours callers go to voicemail and 60% of those don't call back, you're effectively burning 18% of every dollar before the call connects. That's why an AI Voice Rep usually pays for itself in week one.

Bottom line

Don't pick an ad budget. Pick an install target, work backwards, and make sure the phones get answered. The math gets simple after that.
