What Customers Say

AI analysis of 10 Google reviews

Top Strengths

Individual technicians (Miguel Gray, Carter, Geoffrey, Eric) praised as knowledgeable, thorough, polite and efficient
Some customers experienced prompt service and professional demeanor from specific service staff
Ability to identify installation flaws (e.g., exhaust pipe angle issue from 6 years prior)

Areas to Watch

Severe communication failures: multiple missed callbacks, no-show appointments with zero notice, 5-day delays for promised callbacks
Unreliable service delivery: no-shows waste customer time, multiple service visits without resolution
Questionable pricing and sales practices: aggressive upselling ($9000 furnace for 1000 sq ft home), $1500 charge for unresolved fan issue, pushing replacement over repair
Poor product quality or installation: heat pump failed 80% of the time, burst pipes from failed unit, venter fan issues unresolved after multiple visits
Inadequate after-sales support: customers left without heat in winter, directed to call other companies, unable to diagnose defects
Disorganization: described as 'very disorganized,' inconsistent service quality between technicians
missed appointments and no-showspoor communication and callback failuresaggressive upselling and high pricingtechnician quality varies dramaticallyunresolved equipment failures and repeated visits

“

Was punctual and professional.<br><br>Is going to order a part that is needed but got the furnace running in the meantime.<br><br>The original furnace install was 6 years ago and Etic found an install flaw in the exhaust pipe. It was installed at an angle and was leaking condensation.<br><br>Thanks, Eric.
