Oregon requires licensing for hvac contractors
License type: HVAC Contractor License
Licensed through Oregon CCB or BCD. Exam required. EPA 608 certification.
Verify contractor licenseWhen hiring a hvac contractor in Lake Oswego, licensing is your first line of protection. Oregon (OR) requires hvac contractors to hold a valid state license before performing work. This means the contractor has met minimum training, experience, and insurance requirements set by the state. In the Lake Oswego area, always ask for the license number upfront — licensed pros carry liability insurance that covers property damage and injuries on the job, they must follow current building codes, and you have legal recourse through the Oregon licensing board if work is substandard.
Ask for EPA 608 certification (this is a federal requirement, not optional) and whether they are NATE-certified. Check if they perform a Manual J load calculation before recommending system size — contractors who skip this step often sell oversized systems.

Unlicensed HVAC work commonly results in improperly sized systems that waste energy and fail prematurely. Incorrect refrigerant charging voids manufacturer warranties. Venting errors for gas furnaces can cause carbon monoxide leaks, which are a leading cause of accidental poisoning deaths in homes.
An improperly installed AC system loses 15-25% efficiency, costing hundreds of dollars per year in wasted energy. Incorrect ductwork sizing creates hot/cold spots and excessive noise. Improper gas furnace installation is a fire and carbon monoxide hazard. Refrigerant leaks from unlicensed work harm the environment and carry EPA fines up to $44,539 per day.
