A practical guide to scaling your HVAC business. Covers marketing, operations, hiring, customer retention, and the systems you need to grow sustainably.
Matt Franklin
Growing an HVAC business requires more than technical skill. Many excellent technicians struggle to scale because running a business demands different capabilities than fixing equipment.
The 12 steps to grow an HVAC business are: build a professional website, optimise Google Business Profile, establish operational systems, focus on customer retention through service agreements, develop a marketing strategy, hire strategically, price for profit (target 50-55% gross margin on service), expand service offerings, build referral systems, manage cash flow carefully, invest in job management technology, and plan for sustainable growth.
This guide covers 12 actionable steps to grow your HVAC business sustainably, from foundational systems to scaling strategies.
Your website is often the first impression potential customers have. It needs to work hard for your business.
Homepage clarity:
Service pages:
Local optimisation:
Avoid over-complicated websites. Customers want:
A simple, fast, professional website beats an elaborate slow one.
Your Google Business Profile appears when customers search for local HVAC services. This is often the deciding factor in whether they call you.
Reviews significantly impact visibility and conversion:
Keep your profile active with:
Growth without systems creates chaos. Build operational foundations before scaling.
Document processes for:
Written procedures ensure consistency as you add staff.
Manual processes break down as volume increases. Implement job management software that handles:
The right software pays for itself through efficiency gains and reduced errors.
Track parts and materials:
Acquiring new customers costs more than keeping existing ones. Prioritise retention.
Maintenance agreements are valuable for several reasons. They provide predictable recurring revenue, and contracted customers are far more likely to stay with you. You can use scheduled maintenance to fill slow periods, and when systems eventually need replacing, you get the first call. Engaged customers also refer more.
Offer tiered programmes with meaningful benefits at each level.
Retention economics
According to Harvard Business Review, acquiring a new customer costs 5-25x more than retaining an existing one. For HVAC businesses, service agreement customers typically generate 3-4x more lifetime revenue than one-time customers.
After every service call:
Stay connected between service calls to remain top-of-mind.
When issues arise:
How you handle problems often matters more than avoiding them.
Consistent marketing generates consistent leads. Random efforts produce random results.
Focus resources on highest-impact channels:
Create valuable content that attracts customers:
Educational content builds trust and generates organic traffic.
Know what works:
Review monthly and adjust based on data.
Growth requires people. Hiring well is essential.
Signs you need more capacity:
Hire before you're desperate, but not before demand justifies it.
Find quality candidates:
Invest in your team:
Well-trained technicians deliver better work and stay longer.
Many HVAC businesses under-price and wonder why they can't grow. Price correctly.
Calculate true costs including:
Add margin on top of true costs.
Consider different approaches:
Test and refine based on close rates and profitability.
Costs change. Review pricing annually at minimum:
Don't be the cheapest. Be the best value.
Pricing benchmarks
Profitable HVAC businesses typically target 50-55% gross profit margin on service calls and 35-45% on equipment installations. If your margins are significantly below these levels, address pricing before investing heavily in growth.
Growing revenue from existing customers often beats acquiring new ones.
Consider adding:
Additional services increase ticket values and customer stickiness.
Expand carefully into:
Each expansion requires investment in skills and marketing.
Referrals are your best leads. Systematise their generation.
Structure incentives:
Ask at the right moments (after positive experiences).
Build relationships with:
Reciprocal arrangements benefit everyone.
Reviews function as scaled referrals:
Prioritise Google reviews for maximum impact.
Growth requires capital. Poor financial management kills growing businesses.
HVAC businesses face cash flow challenges:
Build reserves during strong periods. Consider lines of credit for smoothing.
Include growth costs in pricing:
Under-pricing prevents investment in growth.
Track key metrics:
Review monthly to identify trends and issues.
Technology amplifies efficiency, enabling growth without proportional overhead increases.
At minimum, implement:
As you grow, consider:
Technology investments typically pay back through efficiency gains.
Growth for its own sake isn't the goal. Sustainable, profitable growth is.
Define what growth means:
Balance ambition with capability.
Growing too fast causes problems:
Controlled growth builds lasting businesses.
Consider eventually:
Today's decisions affect tomorrow's options.
Different stages of growth require different priorities:
Stage 1: Survival (0-$500k revenue) Focus on getting found and delivering quality work. Website, Google Business Profile, and basic systems to handle enquiries professionally.
Stage 2: Stability ($500k-$1.5M revenue) Build recurring revenue through service agreements. Implement proper job management software. Start systematic marketing.
Stage 3: Growth ($1.5M-$5M revenue) Hire strategically. Develop processes that don't depend on you. Expand service offerings. Invest in marketing that scales.
Stage 4: Scale ($5M+ revenue) Build management capacity. Consider geographic expansion. Optimise for efficiency and margin, not just revenue.
Growing an HVAC business is challenging but achievable. The contractors who build systems, invest in people, and operate professionally will capture increasing market share as the industry consolidates.
