HVAC companies face a unique challenge in Google Ads: demand is wildly seasonal. Winter brings emergency heating repairs and furnace replacements. Summer brings AC breakdowns and cooling system upgrades. Spring and fall are quieter, but maintenance calls keep coming in. Most HVAC companies run the same ad campaigns year-round, leaving money on the table during peak seasons and wasting budget during slow periods.
The solution is simple: build your Google Ads strategy around seasonality. Run aggressive campaigns during high-demand months and shift your strategy during slower periods. This guide shows you exactly how.
Understanding HVAC Seasonality
Winter (November–February) is peak season for heating-related work. Frozen pipes, failing furnaces, emergency repairs—customers are desperate and willing to pay. Summer (June–August) brings AC emergencies. Fall and spring are slower but steady.
This seasonality means your keywords, bids, and budget allocation should change throughout the year. The HVAC company that bids aggressively in winter but scales back in summer will generate more leads per dollar spent.
Winter Campaign Strategy
Winter is your revenue season. Double down. This is when you increase bids, expand your keywords, and maximize your budget.
Winter Keywords to Target
- Emergency furnace repair [city]
- Furnace not working [city]
- Furnace replacement [city]
- Emergency heat repair
- Boiler repair [city]
- Heat pump repair [city]
- Pipe bursting repair [city]
- HVAC emergency near me
Bid aggressively on these. A $15 CPC on "emergency furnace repair" that books a $200 service call is a 13x return. These keywords are money-makers in winter.
Winter Campaign Settings
- Budget: Increase by 50–100% compared to off-season
- Bid Strategy: Use Target CPA or Maximize Conversions with a higher target
- Geographic Targeting: All service areas. Don't hold back.
- Scheduling: Run 24/7 ads—emergency HVAC happens at 2 AM
- Landing Page: Emergency furnace repair page, not homepage
Summer Campaign Strategy
Summer brings AC emergencies, but they're less frequent than winter heating crises. Shift your keywords but maintain a steady presence.
Summer Keywords to Target
- AC repair [city]
- Air conditioner not cooling [city]
- Emergency AC repair near me
- Refrigerant leak repair [city]
- AC replacement [city]
- Ductless mini split installation [city]
- HVAC maintenance [city]
Budget during summer should drop 30–50% compared to winter. You're capturing opportunity, not chasing peak demand like in winter.
Spring and Fall Strategy
These shoulder seasons are steady but not explosive. This is when you focus on maintenance and preventative work.
Shoulder Season Keywords
- HVAC maintenance [city]
- Furnace inspection [city]
- AC tune-up [city]
- Preventive HVAC service [city]
- Spring HVAC checkup
Budget should be 60–80% of your peak season. You're generating consistent work with lower customer urgency, so conversions will be lower but more predictable.
The Performance Max Advantage for HVAC
Google's Performance Max campaigns automatically adjust creative combinations and placements across Search, Display, YouTube, and more. For HVAC, this is powerful because it captures demand across channels.
Set up a Performance Max campaign alongside your Search campaigns. Give it a target CPA or target ROAS tied to your typical service call value ($150-$300). Let Google optimize across all channels. Many HVAC companies report 20–40% better return on Performance Max compared to Search-only campaigns.
Geographic Targeting for HVAC Services
HVAC is hyper-local. You only serve specific cities and regions. Use location-based bid adjustments to focus spend where you make the most money.
- Primary service areas: Bid at 100% (baseline)
- Secondary service areas: Bid at 75% (further away, longer response times)
- Tertiary service areas: Bid at 50% or exclude entirely
Use radius targeting around your office or service centers. Set it to your actual service area, not the entire metro area. Wasted budget on calls you can't service is money lost.
Call Tracking and Attribution
HVAC is a phone-call business. Your metric isn't clicks—it's booked jobs. Use dynamic number insertion and call tracking to know which keywords drive actual service calls.
Set up call conversion tracking in Google Ads. Track calls longer than 30–45 seconds as conversions (short calls are usually wrong numbers or scheduling questions). This data tells you which keywords actually book jobs vs. which just get clicks.
Budget Allocation Formula
Here's a simple framework for seasonal budget allocation throughout the year:
- Winter peak (Dec-Feb): 100% budget
- Shoulder (Mar-May, Sep-Nov): 70% budget
- Summer (Jun-Aug): 50% budget
For a company with a $3,000/month baseline budget, that means: $3,000 in winter, $2,100 in shoulder months, $1,500 in summer. Total annual spend is lower but ROI is higher because you're spending aggressively when customers are looking.
Common HVAC Google Ads Mistakes
- Running winter bids in summer – You overpay for clicks when demand is low
- Not tracking calls – You don't know which keywords drive actual revenue
- Bidding nationally or regionally – You pay for clicks from customers too far away to service
- Only advertising emergency repair – Maintenance and replacements are less urgent but higher-value jobs
- Not using landing pages – Generic homepage conversions are weak; service-specific pages crush it
