What Actually Happens During Cold-Climate Heat Pump Service
Cold-climate heat pumps need to be evaluated around real winter heating demands, not just mild-weather operation. ExactAir looks at the home and system together.
Evaluate the Home
Heating requirements, comfort concerns, existing HVAC equipment, and the home's overall conditions are reviewed.
Review Cold-Weather Requirements
The system needs are considered with winter operation in mind, including how the equipment will perform during colder conditions.
Check Airflow & Ductwork
Existing airflow and ductwork conditions are reviewed because the heat pump's performance depends on moving the right amount of air.
Determine Equipment Requirements
Equipment capacity and system configuration are considered based on the home's heating and cooling needs.
Plan the System Setup
Equipment location, connections, controls, electrical requirements, and other installation conditions are reviewed before work begins.
Verify System Operation
The completed system is checked for proper operation, controls, airflow, and overall performance before the job is considered complete.
