Pricing You Can See Up Front
Service Call
$210 standard residential service call.
That total includes a $99 dispatch and $111 diagnostic. The $111 diagnostic does not reduce the repair price. The tech gives a written repair estimate before repair work starts.
No surprise add-ons. You’ll know the repair price before I start work.
360 Maintenance Plans
From $199/year for the current One Visit Spring or Fall 360 plan.
Spring and Fall 360 is $360/year, and Full Year 360 is $499/year. Current geothermal plans and water-heater add-on details are on the maintenance-plan page.
New System Estimate
Free estimates on replacement and new install.
I’ll size it right, show you the rebate paperwork, and put the proposal in writing. No high-pressure sales pitch.
