Job Title: HVAC Technician (Service or Installation)

L.G. Home Comfort is growing across Ontario, and we’re looking for experienced HVAC Technicians to join our team.

Whether your strengths lie in service and troubleshooting or installation and system setup, we want to hear from you. Based on your experience and certifications, you’ll focus on either service, installation, or a mix of both — all within your local and surround regions (no need to travel across the province).

As part of our skilled field team, you’ll work directly with homeowners to deliver exceptional comfort solutions through expert workmanship, professionalism, and customer care.

Key Responsibilities

Depending on your skill set and experience, your duties may include:

Service & Maintenance

Diagnose, troubleshoot, and repair HVAC systems including furnaces, air conditioners, heat pumps, and boilers.
Perform preventive maintenance and emergency service calls.
Read and interpret technical manuals, wiring diagrams, and schematics.
Communicate findings and recommendations clearly to homeowners.

Installation

Install, replace, and commission residential HVAC systems including furnaces, A/Cs, water heaters, and heat pumps.
Ensure installations meet code, manufacturer, and company standards.
Conduct system start-ups and ensure optimal performance.
Lead or assist installation crews depending on project size.

General

Maintain accurate records of work performed through mobile tools or written forms.
Ensure all safety protocols and local HVAC codes are followed.
Keep a clean, organized work area and company vehicle.
Provide excellent customer service and represent the company professionally.

Qualifications

Minimum 3-5 years of HVAC experience (service, installation, or both).
Valid G2 or G1 Gas License required.
313D or 313A Refrigeration License an asset.
ODP (Ozone Depletion Prevention) certification required.
Strong technical, diagnostic, and problem-solving skills.
Ability to work independently and manage time effectively.
Excellent communication and customer service skills.
Valid Ontario driver’s license with a clean driving record.
Physically capable of lifting 50+ lbs and working in various environments (attics, rooftops, crawlspaces).

What We Offer

Competitive hourly pay: $30.00 - $40.00/hr based on experience and licensing or per piece rate sheet.
Health & dental benefits.
Company vehicle, tools, and uniform (where applicable).
On-the-job training and ongoing professional development.
Opportunities for career growth across service, install, or leadership paths.
Supportive and safety-focused work culture.
