AI Answering Service for HVAC Contractors
You can't answer when you're on a rooftop unit or inside an attic. Trillet screens every caller for no heat/no AC emergencies, captures system details and symptoms, and texts them your booking link, so you never miss a furnace failure during a cold snap.
The Old Way
Missed call from 312-555-0198

The Trillet Way
New Emergency: John M. - No Heat, Furnace Not Starting
Today ASAP - $1,200 diagnostic + repair booked
Your dispatch process, handled consistently on every call.
You don't need an AI to say 'leave a message.' You need one that knows if the caller has no heat in 20°F weather or wants a quote for AC replacement in spring, and captures the system details you need to diagnose remotely and prioritize correctly.
Identify
Trillet identifies whether this is an existing customer or new customer, takes a message or transfers for existing customers, and continues to screening for new ones
Screen
Trillet screens for HVAC issue - emergency (no heat in winter, no AC in summer) vs routine (maintenance, efficiency concerns, installation quote), system type, confirms it aligns with your service area and capabilities, flags emergency if applicable, and politely declines if there's no fit
Qualify
Trillet asks your custom intake questions - system age/brand, specific symptoms (noise, smell, cycling, airflow), thermostat readings, residential/commercial, filter changes, timeline/urgency, and your other business-specific questions
Book
If they want to move forward, Trillet texts your booking link, you get a complete summary with system details, urgency and transcript with emergency calls flagged for immediate attention, and the service call appears in your calendar with full context

Success Stories
I was on a rooftop working on a commercial unit when someone called about no heat during a cold snap. Trillet captured the furnace model, symptoms, everything. By the time I came down the ladder, the emergency service call was scheduled. That's $1,400 I would have lost to the next HVAC company.

Why Voicemail Fails for HVAC Contractors
Voicemail
When it's 20°F outside and someone's furnace isn't working, they won't leave a voicemail and wait 3 hours for callback. They immediately call the next HVAC contractor. By the time you finish your current service call and check messages, the $1,200 emergency repair is gone.
Result: Peak season revenue lost. Your busiest time is when you miss the most high-value calls.
Generic AI
They take a name and number. You call back 45 minutes later, customer already found another HVAC company who answered immediately. Generic AI can't tell if it's a no-heat emergency or a spring tune-up inquiry.
Result: Emergency jobs lost. Time wasted on callbacks for customers who already booked elsewhere.
Trillet
We screen for emergency vs routine, capture system type and symptoms, flag urgent situations (no heat/AC), and send booking link. You see 'EMERGENCY: No heat, furnace not starting, 20°F outside' in your notifications while you're on a rooftop.
Result: Emergency calls captured during peak season. You prioritize correctly and never lose high-value urgent work when you're busiest.

Common Questions from HVAC Contractors
An AI answering service answers your phone 24/7, screens customers for emergency vs routine work, captures system details and symptoms, and provides immediate response to time-sensitive calls - without a human dispatcher. Unlike voicemail or basic answering services that just take messages, Trillet runs your full screening protocol so every no-heat or no-AC emergency gets captured with complete diagnostic context, even during peak season rush.
Trillet follows a four-step emergency protocol: First, it identifies whether the caller is a new customer or existing customer. Second, it screens for issue urgency (no heat/AC = emergency, maintenance = routine). Third, it asks your custom screening questions (system type, symptoms, property type). Finally, for emergencies, Trillet flags the call as URGENT and sends immediate notification; for routine work, it texts your booking link. You receive full system details instantly.
Yes - this is Trillet's core strength for HVAC contractors. The AI screens for urgency at the beginning of each call. No heat in 20°F weather or no AC in 95°F gets flagged as emergency. Spring tune-up inquiry gets your booking link. You never waste time on non-urgent callbacks while missing actual emergencies during peak season.
When a customer needs service and wants to schedule, Trillet texts them your calendar link directly during the call. They can book a time that works for both of you. For emergencies, you also get instant notification with full call details including system type and symptoms. No phone tag required.
Trillet will politely explain that your HVAC business doesn't offer that service and end the call professionally. You'll still receive a summary so you know who called and what they needed. This saves you time returning calls for work you don't do.
Yes. Trillet answers 24/7/365, including your busiest times. Peak season (summer for AC, winter for heating) is exactly when you're most likely to miss high-value calls because you're swamped. Trillet ensures you capture every emergency and every AC replacement quote even when you're running 12-hour days.
Trillet starts at $49/month with a 28-day money-back guarantee. That's less than what you make in one hour of service work. Compare that to losing even one $1,200 emergency service call during peak season because you couldn't answer while on a rooftop. One missed call pays for 3+ years of Trillet.
Get started
Don't Let Peak Season Revenue Slip Away.
You can't answer when you're on a rooftop or in an attic - but you can't afford to miss the no-heat call during a cold snap. Set up Trillet before peak season and capture every emergency when it matters most.
