Washington's climate, while generally temperate, can present distinct challenges for HVAC systems, with summers that are warming and can experience prolonged dry spells, and winters that are cool and damp. During AC unit installation, meticulous attention is paid to the proper installation and sealing of refrigerant lines, typically utilizing copper tubing of the correct gauge and diameter, to ensure optimal refrigerant flow and prevent thermal losses.
