Irvin diagnoses 24/7.
Phase Sight AI quotes and dispatches.
Your techs do the repairs.

Phase Sight AI puts a 24/7 virtual HVAC technician, named Irvin, inside every system you service. Irvin clips onto the indoor evaporator and outdoor condenser and measures what a tech would check on a diagnostic call. When something fails, Irvin already knows what and where, and drops a parts-attached quote on your scheduler before the phone rings.

the problem

You're paying techs to diagnose.
You should be paying them to fix.

Every service business owner already knows what's eating margin. Few have ever seen it laid out side by side. These are industry-average numbers for residential and light commercial HVAC.

01 · cost
$340

Average truck-roll cost.

Loaded labor + fuel + dispatcher time for a single visit. Multiply that across every "no fault found" call this month.

02 · waste
22%

Service calls that end in "no fault found."

Almost a quarter of all dispatches are pure cost. The tech rolls, can't reproduce the issue, and goes home. Customer's still upset.

03 · peak
67%

Summer emergencies that are capacitor failures.

Cheap part. Predictable failure curve. Always fails on the hottest week of the year when every tech is double-booked.

04 · churn
31%

Churn rate after a repeat visit.

The fastest way to lose a customer is to come back twice for the same problem. Reviews follow. So does referral pipeline drying up.

Stop paying techs to diagnose. Start paying them to fix.

Irvin watches every system around the clock so techs roll up with the answer, not the question.

simple fixes, costly diagnoses

The fixes are easy. The diagnoses aren't.

Most service calls end in a fix every HVAC tech has done a hundred times. The bottleneck is getting to the diagnosis in the first place, and that's where the truck rolls, the time, and the margin disappear. Phase Sight AI does the diagnosis 24/7 so the truck, the parts, and the quote arrive right the first time.

01 · capacitor

Blown run capacitor.

The most common summer emergency. A $15 part, but it takes a tech with a meter to confirm it, and they're booked solid the week it fails.

Irvin saves $180/ emergency call avoided
02 · no power

System won't turn on.

A tripped breaker, a fried contactor, a dead control board. Three completely different fixes, three different parts. Today, you find out which one when the tech is already on-site.

Irvin saves $150/ false dispatch
03 · frozen coil

Iced-over evaporator.

Could be low refrigerant. Could be a clogged filter. Could be a failing blower. Misdiagnose and you're back in three days, this time eating the labor.

Irvin saves $340/ repeat visit avoided
04 · condensate

Drain pan won't empty.

A $40 cleanout when you catch it. A $4,800 ceiling repair and a damaged customer relationship when the float misses.

Irvin saves $2,500/ water-damage claim avoided
who irvin is for

One truck or one hundred. Irvin scales to you.

Phase Sight AI was built for HVAC shops of every size. Sole technicians, growing businesses, and large residential enterprises all run on the same hardware, platform, and field app. What changes is the leverage.

01 · 1 truck
Sole technicians

Look like a 30-truck operation.

Irvin runs dispatch from your phone. Pre-diagnosed jobs, professional quotes, and scheduling all happen without an office. Take more calls per day because diagnostic time is gone. Build the repeat-customer base small shops live on, with a level of polish your competitors can't match.

02 · 3 to 30 trucks
Small to mid-sized businesses

An extra billable call per truck, per day.

More billable hours per truck. Dispatch by skill match and workload, not by guess. Compete on response time with the larger players in your market. Retention through predictive maintenance becomes a real differentiator, and a recurring revenue line item.

03 · 50+ trucks
Large residential enterprises

Smooth the peak. Protect the install base.

Fleet-level dashboards across every install. Predictive maintenance turns summer emergencies into scheduled visits, smoothing peak-load weeks that wreck operations. Compliance and warranty reporting at scale. Margin protection across thousands of customer relationships.

the hardware

Five signals. Direct measurement. Zero guesswork.

Most HVAC monitoring relies on thermostat temperature: ambient air across the room, a proxy for what's actually happening inside the system. Irvin measures the five signals a tech would clamp on for, directly at the source: pressure, temperature, capacitor, airflow, and condensate. Two devices do the work, one outside at the condenser and one inside at the air handler, with eight core refrigerant points between them. Scroll to step through each sensor, or jump straight to the full Irvin spec sheet.

01 · refrigerant direct measurement

Pressure Sensors

"Direct refrigerant pressure. Where the tech would clamp on."
The problem

Refrigerant pressure tells you charge state, metering device behavior, and whether there are internal restrictions. Most monitoring tools don't measure pressure at all. They infer everything from a thermostat across the room, which only sees the symptom hours after the compressor's already stressed.

The signal

Direct pressure at four refrigerant points: indoor coil inlet and outlet, plus compressor discharge and condenser liquid line outdoors. Paired with the temperature probes (see next), Irvin calculates live superheat and subcooling: the same math a tech does with gauges, but continuously on every system you service.

  • 4 measurement points (indoor coil + outdoor unit, both sides)
  • Slow-leak detection (down to 0.5 psi/day drift)
  • Overcharge / undercharge classification
  • TXV hunting + restriction patterns
  • Paired with temperature for live superheat + subcooling

02 · refrigerant + air superheat + subcooling

Temperature Probes

"Superheat and subcooling. Calculated, not guessed."
The problem

Thermostats read ambient air across the room. By the time the house gets warm, a slugged compressor, a failing TXV, or a frozen coil has already been damaged for hours. The temperatures that matter are at the metal: where the refrigerant changes phase and where the air actually hits the coil.

The signal

Six dedicated thermistors at the points a tech would clamp on: liquid + suction lines outdoors, distributor + suction lines on the evaporator, plus return + supply air in the ducts. Paired with the pressure sensors at the same fittings, Irvin calculates live superheat and subcooling: exactly the values a tech reads off gauges, continuously.

  • Suction + liquid line temps (outdoor) for subcooling math
  • Distributor + suction line temps (indoor) for TXV verification
  • Return + supply air temps for delta-T (16 to 22°F target)
  • Compressor discharge alert above 225°F
  • Continuous superheat + subcooling trending

03 · electrical predictive MFD

Capacitor Sensor

"Replace it before the 100° heatwave, not during."
The problem

Run capacitors drift out of spec quietly. The first sign is usually a hard-start failure on the hottest day of the year, when every tech is already double-booked.

The signal

Live microfarad measurement on every start cycle. Irvin flags capacitors approaching end-of-life weeks before they fail, so you replace on a scheduled call, not an emergency.

  • Per-cycle MFD measurement
  • Drift trending with confidence interval
  • End-of-life prediction (typically 4–6 weeks ahead)
  • Hard-start vs. soft-start classification

04 · airflow duct pressure

Static Airflow Sensor

"Duct problems kill compressors. Catch them upstream."
The problem

A clogged filter or restricted return raises static pressure, which starves the evaporator, which freezes the coil, which burns the compressor. By the time the customer calls, the damage is done.

The signal

Continuous static pressure across the air handler. Restrictions, blower issues, and damper failures get flagged before they cascade into compressor damage.

  • Supply + return static pressure
  • Filter loading prediction
  • Blower performance baselining
  • Damper + duct restriction alerts

05 · condensate float + level

Float Sensor

"The cheapest sensor. The most expensive miss."
The problem

Condensate overflows are the #1 source of warranty water damage claims in residential HVAC. A $4 float switch failure can mean a $40,000 ceiling repair.

The signal

Redundant condensate level monitoring with predictive trending. We see the pan filling before the float trips, and flag slow drain issues weeks before they become floods.

  • Primary + secondary pan monitoring
  • Drain restriction trending
  • Float-switch health verification
  • Auto-escalation on rapid level rise

the impact

Built for the metrics that move the business.

Numbers that resonate whether you're running a 3-truck shop chasing repeat customers or a 30-truck operation chasing fleet efficiency.

01 · operations
↓42%

Truck rolls reduced

Fewer dispatch decisions. More margin per call. Capacity recovered for revenue-generating jobs instead of "no fault found" visits.

02 · labor
89%

First-time fix rate

Right part on the truck. Right diagnosis in hand. Industry average sits around 76%. Every point above it is recovered profit.

03 · efficiency
↓73%

Diagnostic time per call

From 45 minutes of guessing on-site to 10 minutes of confirming what the sensors already told you. That time becomes more calls per tech per day.

04 · retention
↑23%

Customer retention lift

Customers don't churn after a tech who shows up already knowing the issue. Especially small-shop differentiator: this is how you build a repeat base.

05 · recurring
3.4×

Service contract attach

Predictive maintenance is an easier sell when the data backs it. Every install becomes a candidate for a recurring monitoring contract.

06 · margin
$52K

Recovered labor per tech, annually

What you stop losing to misdiagnosed calls, wrong-truck dispatches, and same-day reschedules. Pure margin back to the business.
