How do I know if my HVAC technician did a good job

A good HVAC technician should leave clear signs of professional work, proper testing, and thorough documentation. You can evaluate their work quality through several key indicators that demonstrate both technical competence and professionalism.

Professional conduct and preparation are your first clues. A quality technician arrives on time with proper identification, explains the work needed, provides written estimates for major repairs, and uses appropriate tools and safety equipment. They should wear shoe covers or remove shoes, lay down drop cloths to protect your floors, and treat your home with respect.

Technical work quality becomes evident through their systematic approach. Good technicians test system operation before and after their work, check gas connections with leak detection solution, measure temperatures and pressures, inspect electrical connections, and verify proper airflow. For furnace work, they should test the heat exchanger, check venting, and ensure proper combustion. They'll also replace or clean filters and check your thermostat operation.

Documentation and follow-up separate professionals from amateurs. Quality technicians provide detailed invoices showing parts used and work performed, explain what they found and what they fixed, offer maintenance recommendations, and ensure you understand how to operate your system properly. They should also clean up completely, removing all packaging and old parts unless you request to keep them.

In Ottawa's HVAC market, reputable contractors carry TSSA licensing for gas work, maintain WSIB coverage, and provide warranties on their work. They'll pull proper permits when required and can show you their credentials. A good technician will also educate you about your system, pointing out potential future issues and explaining maintenance needs specific to Ottawa's climate.

Red flags include rushing through the job, inability to explain the problem clearly, pressure tactics for expensive repairs, cash-only payment requests, or leaving without testing the system. If your technician can't show proper licensing or seems unfamiliar with TSSA requirements, that's a serious concern.

For peace of mind with your HVAC work, consider working with established Ottawa contractors who offer transparent pricing and stand behind their work with solid warranties.
