Here's the problem. You're on a roof, in a crawl space, or elbow-deep in a panel. Your phone rings. You can't answer. The caller doesn't leave a voicemail. They call the next contractor on Google. You just lost a $500-$15,000 job because your hands were full.
This happens 3-5 times a day for most contractors. Multiply that across a month and you're looking at $10,000-$50,000 in revenue that just walked away. AI answering services fix this by picking up every single call, qualifying the lead, and in some cases, booking the appointment right there on the spot.
But not all AI answering services are the same. Some are built for dentists and lawyers and have no idea what a condenser coil is. Others are cheap but can't actually book anything. We tested seven of the most popular options and ranked them specifically for contractors -- HVAC, plumbing, electrical, roofing, and general contracting.
Quick comparison table
Here's the full picture before we break each one down. Pay attention to the "Contractor-Specific" and "Emergency Dispatch" columns. Those are what separate tools built for you from tools built for everyone.
| Service | Price | Contractor-Specific | Books Appointments | Emergency Dispatch |
|---|---|---|---|---|
| Call2Calendar | From $299/mo | Yes (deep) | Yes (during call) | Yes (30 sec) |
| Rosie AI | From $49/mo | Partial | Yes | No |
| Smith.ai | From $292/mo | No (general) | Yes | Limited |
| Goodcall | From $59/mo | No (general) | Yes | No |
| Dialzara | From $29/mo | No (general) | Yes | No |
| SkipCalls | $1.90/wk | Basic | Yes | No |
| LeadTruffle | From $229/mo | Yes | After call | No |
Now let's get into what each one actually does, what it costs, and where it falls short.
#1 Call2Calendar -- Best for Contractors
Call2Calendar is the only AI answering service built from the ground up for home service contractors. The AI receptionist -- her name is Jessica -- doesn't just answer calls. She speaks your trade. Ask her about a compressor replacement, a main line backup, or a 200-amp panel upgrade and she knows what you're talking about. That matters, because when a homeowner calls and the person answering sounds clueless about HVAC, plumbing, or electrical work, they hang up.
Pricing
Flat monthly pricing starting at $299/month. No per-call charges. No per-minute charges. No after-hours premiums. Your July bill is the same as your January bill. For a contractor doing 150-300 calls a month, that works out to roughly $1-2 per call -- compared to $3-5+ per call with answering services or per-minute AI tools.
What makes it different
- Books appointments during the call. Not after. Not via text follow-up. While the homeowner is on the phone, Jessica checks your calendar and books the job. By the time you climb off the roof, the appointment is on your schedule with the customer's name, address, and what's wrong.
- Emergency dispatch in 30 seconds. Pipe burst at 2 AM? Jessica doesn't just take a message. She gets your on-call tech on the phone within 30 seconds. The homeowner stays on the line. No callback. No delay. No lost job.
- Trade-specific training. Jessica knows the difference between R-22 and R-410A. She knows what "my breaker keeps tripping" means. She asks the right qualifying questions for each trade -- property type, equipment brand, age of system, urgency.
- Spam call filtering. If it's a warranty scam or a robocall, Jessica handles it so you never see it. You only get notified about real customers.
- Done-for-you setup. You don't configure anything. The Call2Calendar team sets up Jessica for your specific business, your service area, your pricing, your calendar. Takes about 48 hours. You just forward your calls.
Limitations
- Higher price point than budget options (but you get what you pay for)
- Currently focused on home service trades -- not ideal if you're a general SaaS business
- No self-service plan for contractors who want to configure everything themselves
Best for: Contractors who want every call answered, every job booked, and every emergency handled -- without lifting a finger.
Try it yourself right now. Call (610) 890-4822 and tell Jessica your AC just died. See how she handles it. That's exactly what your customers experience 24/7.
Hear Jessica handle a real call.
Call her right now. Pretend you need an emergency plumber or your AC is out. Then imagine that working for your business around the clock while you're on the job.
#2 Rosie AI -- Best Budget Option
Rosie is an AI phone answering service that markets specifically to small businesses, including some contractor verticals. It's one of the more affordable options that still offers real appointment booking capability.
Pricing
Plans start at $49/month for a limited number of calls, scaling up based on volume. Higher tiers run $99-199/month. Per-call overage charges apply if you exceed your plan's limit, so you need to estimate your volume accurately or risk surprise bills during busy months.
Best features for contractors
- Clean, simple call answering with customizable greetings
- Can book appointments through calendar integrations
- Text message follow-ups to callers
- Decent natural-sounding voice
- Call transcripts and summaries sent to you
Limitations
- Not deeply trained on trade terminology -- "partial" contractor knowledge at best
- No emergency dispatch capability. A 2 AM pipe burst gets the same treatment as a Tuesday afternoon quote request
- Per-call overage charges can add up during summer rush or Monday morning floods
- Setup is largely self-service -- you build the scripts and flows yourself
Best for: Solo contractors or small shops on a tight budget who want basic AI call answering without a big monthly commitment.
Watch out for overages. Rosie's base plans have call limits. If you're an HVAC company going into summer, your call volume could double or triple. That $49/month plan might become $150+ by July. Make sure you understand the overage pricing before you commit.
#3 Smith.ai -- Best AI + Human Hybrid
Smith.ai combines AI with live human receptionists. The AI handles straightforward calls, and humans step in for complex conversations. It's a well-known brand in the virtual receptionist space, primarily serving law firms and professional services.
Pricing
Starts at $292.50/month for 30 calls. Additional calls cost $9.75 each. That per-call pricing adds up fast. A contractor handling 200 calls a month would pay roughly $1,950/month. The AI-only plan is cheaper but loses the human backup that makes Smith.ai attractive in the first place.
Best features for contractors
- Human receptionists available for complex or sensitive calls
- Appointment booking through popular calendar tools
- CRM integrations (Salesforce, HubSpot, etc.)
- Bilingual support (English and Spanish)
- Lead intake and qualification
Limitations
- Not built for contractors. The platform is general-purpose, designed for lawyers and consultants. Nobody on their team has trained the AI on trade-specific conversations
- Expensive at volume. 200 calls at $9.75 each = $1,950/month on top of the base fee
- Limited emergency dispatch. Humans can call you for urgent situations, but there's no built-in 30-second dispatch workflow for on-call techs
- Hold times possible during peak hours since human receptionists are shared across clients
Best for: Contractors who want a human safety net and don't mind paying a premium for it. Works best for lower call volumes where the per-call cost doesn't destroy your margins.
The math problem: Smith.ai is solid for 30-50 calls a month. But contractors in busy season can see 200-400 calls. At $9.75 per call, your bill goes from $292 to $2,000+. For that money, you could get a dedicated solution built for your trade.
#4 Goodcall -- Best for High Call Volume
Goodcall is an AI phone agent platform backed by Google. It handles inbound calls with conversational AI and focuses on small businesses across multiple verticals, including some home services. The Google connection means solid voice recognition and natural language processing.
Pricing
Plans start at $59/month for the basic tier. Business plans with more features run $99-199/month. Pricing is generally flat-rate within tiers, which protects you from per-call billing surprises. Good for contractors with unpredictable call volume.
Best features for contractors
- Google-powered AI voice technology -- callers often don't realize they're talking to AI
- Automated appointment scheduling
- SMS follow-ups and confirmations
- Call analytics and reporting dashboard
- Can handle multiple simultaneous calls (no hold times during Monday morning rushes)
Limitations
- General-purpose AI. Doesn't understand HVAC, plumbing, or electrical terminology out of the box. You can train it somewhat, but it's not the same as a purpose-built solution
- No emergency dispatch. Can't get your on-call tech on the phone for a gas leak at midnight
- Setup requires you to build your own call flows and scripts
- Limited integration with field service management software that contractors actually use (Housecall Pro, ServiceTitan, Jobber)
Best for: Contractors who get a high volume of straightforward calls (quote requests, scheduling) and want a solid, affordable AI answering platform without paying per-call.
#5 Dialzara -- Cheapest Option
Dialzara is a budget AI answering service that focuses on affordability. It answers calls, captures caller information, and can handle basic scheduling. For contractors who are currently sending everything to voicemail, it's a massive upgrade at a minimal price.
Pricing
Starts at $29/month, making it one of the cheapest AI answering options available. Higher tiers with more minutes and features run $49-99/month. Per-minute overage charges may apply depending on your plan, so read the fine print.
Best features for contractors
- Rock-bottom pricing for basic call answering
- Customizable AI voice and scripts
- Call transcripts and summaries
- Basic appointment scheduling
- Easy setup -- can be running in under an hour
Limitations
- You get what you pay for. The AI is general-purpose and won't understand trade-specific questions
- No emergency dispatch at all
- Limited integrations -- won't connect with most field service management tools
- Voice quality and conversation flow aren't as polished as pricier options
- Caller experience can feel robotic on complex conversations
Best for: Solo contractors or startups who are currently missing every call and need something -- anything -- answering their phone at the lowest possible cost.
The "better than voicemail" problem: Dialzara is absolutely better than voicemail. But "better than voicemail" is a low bar. If a homeowner calls about a gas smell and the AI fumbles the conversation, you've got a liability issue and a lost customer. Budget tools work for simple calls. Emergencies and complex situations need more.
#6 SkipCalls -- Best Ultra-Budget
SkipCalls is the least expensive AI answering option on the market, coming in at just $1.90 per week. It provides basic call answering, message-taking, and simple scheduling for small businesses that want to dip their toes into AI without any real financial commitment.
Pricing
$1.90/week. Less than $8/month. That's a cup of coffee at Wawa. Even the most budget-conscious one-truck operation can afford this. Higher tiers with more features are available but still remarkably cheap.
Best features for contractors
- Absurdly affordable -- there's no financial reason not to try it
- Basic call answering and message capture
- Simple appointment booking
- SMS notifications when calls come in
- No long-term contracts
Limitations
- Very basic AI capabilities. Don't expect nuanced trade conversations
- No emergency dispatch
- Limited customization options
- No CRM or field service management integrations
- May struggle with complex caller requests or multiple question conversations
Best for: Brand-new contractors or side hustlers who need basic call coverage while they build their business. A stepping stone, not a long-term solution.
#7 LeadTruffle -- Best for Lead Capture
LeadTruffle is specifically built for home service businesses and focuses on lead capture and qualification. It integrates with Thumbtack, Angi, and other lead sources, which makes it interesting for contractors who get a lot of inbound leads from those platforms. The AI answers calls, qualifies leads, and routes them to your team.
Pricing
Starts at $229/month. Higher tiers for multi-location businesses run $399-599/month. No per-call charges on most plans, which is good. But the base price is higher than most budget options, putting it in the mid-tier range.
Best features for contractors
- Built for home services -- understands the industry
- Integrations with Thumbtack, Angi, and HomeAdvisor
- Lead qualification with trade-specific questions
- CRM-style lead management dashboard
- Follow-up sequences via text and email
Limitations
- Appointments are booked after the call, not during it. The AI captures info and then follows up to schedule. That delay means some leads go cold
- No emergency dispatch
- More of a lead management platform than a true phone receptionist -- the caller experience isn't as conversational
- Higher price than budget options without the deep AI phone capabilities of top-tier services
- Best value comes from Thumbtack/Angi integrations, which not every contractor uses
Best for: Contractors who get heavy lead flow from Thumbtack and Angi and want a system that captures, qualifies, and follows up with those leads automatically.
The "after call" booking problem: LeadTruffle captures lead info during the call but schedules the appointment afterward via text follow-up. Research shows that booking during the live call converts 3-4x better than post-call follow-up. By the time the follow-up text goes out, that homeowner may have already booked with someone else.
What to look for in an AI answering service
Before you pick one, here are the six things that actually matter for contractors. Not features on a marketing page. Things that determine whether you book jobs or lose them.
1. Trade-specific training
Does the AI know what a compressor is? Can it ask the right questions when someone calls about a tripping breaker vs. a flickering light? General-purpose AI answering services are built for dentists, lawyers, and SaaS companies. When a homeowner calls your plumbing company and the AI doesn't understand "my water heater is leaking from the pressure relief valve," you've lost a $1,200 job. Look for a service that's trained specifically on HVAC, plumbing, electrical, and roofing terminology and scenarios.
2. Appointment booking -- during or after the call?
This is the single biggest differentiator. Some AI services book the appointment while the customer is still on the phone. Others capture the info and follow up later by text or email to schedule. The difference in conversion rate is massive. A homeowner whose AC just died in July isn't waiting for a text. They're calling the next contractor. Book during the call or lose the job.
3. Emergency handling
Gas leak. Flooding basement. Sparking electrical panel. These calls can't wait until morning. Can the AI escalate to your on-call tech immediately? Can it conference the homeowner and the tech together? Or does it just take a message and hope you see it before the homeowner calls someone else? For any contractor who offers emergency services, this is non-negotiable.
4. Pricing model -- flat vs. per-call
Per-call or per-minute pricing punishes you for being busy. Your busiest month is also your most expensive month. Flat-rate pricing means your July costs the same as your February. For contractors with seasonal volume swings, flat pricing is the only model that makes sense. Calculate what you'd pay during your busiest month, not your slowest. That's your real cost.
5. Integration with your software
Do you use Housecall Pro? ServiceTitan? Jobber? Google Calendar? The AI needs to connect to whatever you use to manage your schedule. If it can't sync with your existing tools, you're back to manually entering appointments, which defeats the whole purpose. Check the integration list before you sign up.
6. Setup and support
Some services give you a blank canvas and say "build your own scripts." Others do the setup for you. Be honest with yourself about how much time you have to configure an AI system. If you're running a crew, managing jobs, and doing estimates, you probably don't have 10 hours to set up call flows. Done-for-you setup is worth paying for because it means the system actually gets implemented instead of sitting half-configured for three months.
The bottom line
Every service on this list is better than sending your calls to voicemail. That's a given. The question is which one matches your business.
If you want the most complete solution built for contractors: Call2Calendar. Trade-specific AI, real-time appointment booking, emergency dispatch, flat pricing. It's the most capable option for HVAC, plumbing, electrical, and roofing businesses.
If you're on a tight budget and just need something answering: Rosie AI or Dialzara. They won't understand your trade deeply, but they'll capture leads that would otherwise go to voicemail.
If you want human backup for complex calls: Smith.ai. Just watch the per-call costs during busy season.
If you get leads from Thumbtack or Angi: LeadTruffle. The platform integrations make it useful for managing that specific lead flow.
If you want to try AI for almost nothing: SkipCalls at $1.90/week. You've got nothing to lose.
The biggest mistake contractors make is doing nothing. Every day without an AI answering service is another day of missed calls, lost jobs, and revenue walking out the door. Pick one. Try it. See what happens to your booking rate.
The second biggest mistake is picking a general-purpose tool and wondering why it can't handle a call about a leaking expansion tank. If you're in the trades, use something built for the trades.
