Frequently Asked Questions

HVAC IQHUB is a smart monitoring system that connects to your HVAC equipment and provides real-time temperature readings, amp draw monitoring, AI-powered diagnostics, and instant alerts when something goes wrong. It's like a check engine light for your heating and cooling system.

1. Install the hub near your HVAC equipment (or have a technician install it)
2. Connect sensors - temperature probes and amp clamps attach to your system
3. Hub sends data via built-in LTE cellular (no WiFi needed)
4. View dashboard - see real-time stats, history, and AI diagnostics on web or mobile
5. Get alerts - receive notifications when issues are detected

No! The homeowner dashboard is designed to be simple - you'll see green/yellow/red status indicators and plain-English explanations. However, if you want to install the hardware yourself, basic familiarity with HVAC equipment is helpful. We recommend professional installation for most users.

• IQHUB monitoring hub (nRF9151 LTE cellular)
• 3x DS18B20 temperature probes (supply, return, outdoor)
• CT clamp for amp monitoring
• Mounting hardware and cable ties
• Quick start guide

The hub has built-in LTE cellular - no WiFi or SIM card required!

No! The IQHUB uses LTE cellular data (included in your subscription). This means it works in basements, utility closets, and rental properties where WiFi access is difficult. It's also more reliable than WiFi for 24/7 monitoring.

Yes, if you're comfortable working around HVAC equipment. The temperature probes just attach with thermal tape, and the CT clamp clips around a wire (no electrical work required). However, we recommend professional installation for:

• Warranty purposes
• Optimal sensor placement
• 24V terminal monitoring setup

Many HVAC contractors offer installation as part of a maintenance visit.

IQHUB works with virtually any residential or light commercial HVAC system:

• Gas furnaces (80% and 90%+)
• Electric furnaces and heat strips
• Heat pumps (air source and geothermal)
• Central air conditioners
• Mini-split systems
• Boilers with forced-air handlers

• Hardware: $449 one-time purchase
• Single System: $25/month - perfect for homeowners
• Landlord Pro: $19/month per system (2+ properties) - includes multi-property dashboard

Both plans include LTE cellular data, AI diagnostics, 3-year data history, and all alert types. See our pricing page for details.

No contracts! You can cancel your subscription anytime. Service continues until the end of your current billing period. The hardware is yours to keep.

If you cancel your subscription:

• Service continues until end of billing period
• The hardware stops sending data (no active cellular)
• Historical data is retained for 90 days
• You can reactivate anytime by resubscribing

• Temperature alerts: System not heating/cooling, extreme temps
• Equipment alerts: High amp draw, short cycling, long run times
• AI diagnostics: Dirty filter, refrigerant issues, flame sensor problems
• Offline alerts: Hub disconnected or power loss

You can customize alert thresholds and notification preferences (email, SMS, push).

Yes! You can invite your HVAC contractor to view your system data. They'll see real-time readings and history, which helps them diagnose issues before arriving on-site. You control access and can revoke it anytime.

We store 3 years of historical data, allowing you to:

• Compare heating seasons year-over-year
• Track equipment degradation over time
• Provide data to contractors for maintenance
• Verify repair effectiveness

1. Check power: Is the LED on the hub lit?
2. Check location: Metal enclosures can block cellular signal
3. Power cycle: Unplug for 30 seconds, then reconnect
4. Check subscription: Ensure your subscription is active

If issues persist, contact support with your device ID.

• Check probe placement: Supply probe should be in the supply plenum, not touching metal
• Verify connections: Ensure probes are fully plugged in
• Allow calibration time: Readings stabilize after 15-30 minutes
• Compare to thermostat: Return air temp should be close to your thermostat reading

1. Check notification settings: Go to Settings → Notifications in your dashboard
2. Verify email/phone: Ensure your contact info is correct
3. Check spam folder: Add our email to your contacts
4. Review alert rules: Make sure the alert type is enabled
