Identify included and retained heat sources.
Ask which equipment remains usable and how it relates to the new system. Name any backup equipment separately in the proposal.
HVAC · Medina, Washington
HVAC in Medina, WA.
HVAC in Medina should make the backup heating arrangement understandable to the household. Ask what happens when the main heating equipment cannot meet the demand or is unavailable, rather than assuming a second heat source is included.
Evergreen Home Pro helps you connect that operating question to the proposed equipment. Bring information about retained heating systems and the controls currently used in the home.
Heating and cooling
Clarify normal, backup and emergency operation.
Have the contractor explain which heat sources the proposal includes and how the controls use them. Automatic supplemental operation and a manually selected emergency mode are equipment-specific questions, not interchangeable labels.
Ask how the transition is controlled.
Discuss the selected controls and when another heat source operates. Avoid assuming every heat pump has the same modes or transition settings.
Practice the homeowner controls.
Request operating instructions for the installed arrangement and a demonstration of applicable modes. Ask whom to contact if the expected transition does not occur.
Before work begins
Coordinate mechanical and electrical responsibilities.
Medina’s FAQ lists mechanical permits for adding, replacing, repairing or altering equipment such as furnaces, air conditioners and heat pumps. Describe retained and new heat sources as part of the actual system.
The city’s inspection page assigns electrical permitting and inspections to Washington L&I. Confirm who handles electrical changes associated with the proposed equipment.
HVAC questions for Medina homeowners.
Does every heat pump include backup heat?
No. Ask which heat sources and control functions are included in the exact proposed arrangement.
Is emergency mode the same as automatic supplemental heating?
Ask the contractor to explain the installed controls. Those terms can describe different functions and should not be assumed equivalent.
Does a city mechanical inspection complete electrical review?
Confirm the separate electrical requirements. Medina directs electrical permits and inspections to Washington L&I.
