HVAC, from thermostat to refrigerant.

Heating, ventilation, and air-conditioning support spans residential service calls, commercial RTUs, and refrigerant compliance. Tier-1 questions repeat by manufacturer — Carrier, Trane, Lennox, Daikin, Goodman, Mitsubishi — and 60% of them are seasonal.

The tier-1 questions Truvyo answers

Built around the questions your support team hears every day for homeowners, building managers, and HVAC installers.

Common ticket	What we ground it in
Thermostat blank or not responding	Carrier Infinity, Honeywell Pro Series, ecobee, Nest
Outdoor condenser won't start	all split-system brands, capacitor and contactor faults
Low cooling capacity / iced evaporator	filter restrictions, refrigerant charge, blower issues
Error codes and fault lights	manufacturer-specific code lookups across 12+ brands
Refrigerant + EPA section 608 questions	R-410A phase-out, R-454B transition
Heat-pump in cold weather	defrost cycles, aux/emergency heat behavior

Brands and equipment in scope

A representative slice of the shared library we maintain for the hvac vertical. Each tenant adds their proprietary catalog on top.

Carrier, Trane, Lennox, Daikin, Goodman, Mitsubishi, Bryant, Rheem, York, Bosch, ecobee, Honeywell, Nest, Tempstar.

Don't see a brand? The auto-update pipeline ingests new vendor docs quarterly. Customers can drop in their own SOPs at any time via the tenant overlay.

Example evidence-graded articles

Every answer cites its source. Articles graded Official come from manufacturer documentation; Field-corroborated means at least two independent expert sources agree; Unverified never reaches a customer.

Article	Source mix
Carrier 19DV chiller — fault code 178	OEM service manual + Carrier dealer bulletin
Goodman GSX condenser — won't start in summer	Goodman tech support article + ACCA best-practice guide
R-454B refrigerant compliance — what installers need to know	EPA + AHRI joint guidance

What you get out of the box

Curated shared library

The hvac library ships pre-loaded. Your tenant inherits every article on day one — no manual upload needed.

Tenant overlay for your IP

Drop in your own SOPs, brand voice, and policies via /v1/admin/import-kb. Stays private to your tenant — write-only, never extractable.

Two-tag embed

One script tag on your support site. Theming via CSS variables. Handoff hooks for your live-agent flow.

Add-on: Billing Connect Q4 2026 · Upcoming

Connect your billing system — Stripe, QuickBooks, NetSuite, or your in-house DB — so the agent can answer customer-specific billing questions in their own words:

"When does my next invoice run?" → grounded in the customer's actual subscription record
"Update the card on file." → routes the customer to a hosted Stripe portal, with the answer scoped to their account
"Cancel my plan effective end of month." → triggers the cancellation flow with audit-logged consent

Data flows IN — the agent reads the customer record by tenant-scoped identifier. Data never flows OUT — no extract endpoint exists, no bulk dump, no exfiltration path. Write-only sovereignty extended to live customer records.

Available as an add-on (additional monthly fee) starting Q4 2026. Email us to get on the early-access list.
