The complete sales system for HVAC contractors

It's 2am in February. A homeowner's furnace just died. They're scrolling through their phone, calling every HVAC shop they can find. Whoever picks up first gets a $4,000 emergency replacement job.

Are you that shop? Most aren't.

WebDevAuto is the complete sales system that picks up the 2am call, books the emergency, and follows up — engineered specifically for HVAC contractors.

Calculate what missed calls cost your HVAC shop

What missed calls actually cost an HVAC contractor

The data on missed calls in HVAC is unambiguous:

27%¹
of HVAC inbound calls missed year-round
climbs above 35% at peak season — heat waves, cold snaps, storm weeks
31%¹
of HVAC emergency calls come in after hours
after-hours AC replacements run $3,000–$8,000 — these are your highest-value calls
78%²
of callers won't leave voicemail
they hang up and dial the next contractor on the search results page
$45K–$120K²
lost per year to missed calls
across a study of 1,200+ contractors (vendor-published — directionally well-supported)

Every leak above is recoverable. The fix is a system that picks up before the next contractor does — at 11pm, on Sunday, in the middle of a heat wave.

What does the leak look like at your HVAC shop?

Plug in your average service ticket, replacement ticket, weekly call volume, and rough miss rate. The Missed-Call Cost Calculator returns a real dollar figure in 60 seconds.

Alex answers every HVAC call. 24/7. Including the 2am furnace failure.

Alex is the AI receptionist tuned specifically for HVAC contractors. He picks up on the first ring — no matter what hour, no matter where your techs are.

He runs a real HVAC intake conversation:

▸"What's going on with the system? It's not cooling? It's making a noise? When did it start?"
▸"How old is the unit? Do you remember the brand?"
▸"Is it a complete loss, or is the AC still running but not keeping up?"
▸"What's the address and what's the best number to reach you?"

He knows what's an emergency. Alex flags emergency keywords — "no heat," "no AC," "water leak from furnace," "gas smell," "electrical burning smell" — and routes them differently from routine service calls. Emergencies escalate to your on-call tech via SMS within 60 seconds. Non-urgent calls go straight onto next-available service slots.

A website that books emergency calls — not just looks pretty

Your website is the highest-volume salesperson in your HVAC business. For HVAC specifically, it's also the trust signal that decides whether a panicked homeowner with a dead furnace clicks "call now" or scrolls to the next result.

WebDevAuto sites for HVAC are engineered to:

▸Load in under 2 seconds — Google's Core Web Vitals research shows mobile users abandon sites that take longer
▸Surface emergency CTAs above the fold — "Call now for emergency service" with a tap-to-call link, not buried in a contact page
▸Display service area clearly — homeowners in zip codes you don't service shouldn't waste your phone time
▸Show financing prominently — HVAC replacements are big-ticket; consumer financing options integrate directly into the site
▸Rank locally — technical SEO done right, so when someone searches "HVAC repair [your city]" or "emergency AC repair near me" you actually appear

The 30-second SMS rescue for the calls Alex can't catch

Even with Alex on the front line, calls slip through — your system has high call volume during a heat wave, the call drops, the caller hangs up before Alex finishes greeting.

Within 30 seconds of any unanswered call, the system fires off a personalized SMS:

"Hey — this is [your shop]. I missed your call. What's going on with the system? I can text you back in 5 minutes or get you on the schedule."

The SMS is HVAC-aware. If the caller's number is in your CRM as a past customer, the message is personalized: *"Hey [name] — sorry I missed you. I see we worked on your system in October. What's going on?"*

How missed-call automation works

Annual tune-ups and seasonal campaigns — recurring revenue most shops leave on the table

Your existing customer list is the most underused asset in your business. Every system you installed needs an annual maintenance check. Every customer who declined a recommendation 18 months ago is due for a follow-up.

The CRM automatically tracks:

▸System install date and warranty status
▸Recommended services declined ("customer declined coil cleaning — flag for next visit")
▸Annual maintenance reminders (timed for spring AC, fall heating tune-ups)
▸Filter replacement reminders (scaled to system type and household)

Six months after a tune-up, the system automatically sends: *"Hey — your system is due for a fall heating check before the cold hits. Want me to get you on the schedule for next week?"* That single feature recovers more revenue per dollar invested than any new-customer marketing channel.

Lead Finder — for HVAC shops ready to grow beyond Angi and HomeAdvisor

Available as a Custom Engineering add-on for Growth System customers. Lead Finder is our proprietary local prospecting engine, tuned specifically for HVAC.

Every HVAC deployment includes:

▸A discovery call to map your service area, ideal customer profile, and equipment specialties (heat pumps? geothermal? commercial?)
▸A custom-tuned outbound campaign — "homeowners in [zip] with systems older than 12 years" looks different from "small commercial buildings with rooftop unit replacements"
▸DNC compliance, state-by-state outbound rules, per-message review or auto-send
▸Direct integration with your CRM so warm prospects flow into the same inbox as inbound calls

Why this isn't ServiceTitan or Housecall Pro — for HVAC specifically

ServiceTitan dominates HVAC software. Housecall Pro and Jobber serve smaller shops. FieldEdge is the legacy alternative. They're all good operations software — invoicing, dispatch, GPS truck tracking, parts inventory, payroll integration.

WebDevAuto isn't competing with that. We're the client-acquisition layer those tools assume you've already solved.

	ServiceTitan / Housecall Pro / FieldEdge	WebDevAuto
What it does	Manages your shop operations end-to-end	Gets you customers and converts the calls you'd otherwise miss
Best for	Shops with established lead flow + ops complexity	Shops losing leads to slow phones + outdated websites
Where it fits	After the lead becomes a job	Before the lead becomes a job
Pricing	$300+/mo per tech minimum at ServiceTitan; HCP starts ~$65/mo	$499/mo flat for the Growth tier

Too small for ServiceTitan? Too DIY for HighLevel? We're built for the HVAC shop in between.

Pricing built for HVAC shops at every stage

For most HVAC shops with steady call volume, Growth System is the right starting point — Alex AI voice agent, AI lead qualification, missed-call automation, CRM with seasonal rebooking, and Google Maps optimization. Alex handles the 2am emergency calls so you don't have to.

Tier	Setup	Monthly	Best for
Foundation	$1,500 (or split)	$99/mo	Solo techs or new shops needing a real website first
Growth System ⭐	$2,999 (or 3× $999)	$499/mo (Alex AI voice included)	Established shops losing emergency calls and after-hours leads

ROI math for a typical HVAC shop: if you currently miss 4 calls/week at an average $400 service ticket, you're losing $1,600/week — about $83,000/year. Growth tier with the voice add-on is $9,576/year. Math: pays for itself in the first 6 weeks.
