Frequently asked questions
Is a permit required to replace a heat pump?
Nearly every building department treats equipment changeout as permitted mechanical work, and most also require an electrical permit when the disconnect or circuit changes. Confirm the requirement with the local authority before the equipment is ordered.
Should the indoor unit be replaced at the same time?
Manufacturers rate efficiency for matched pairs. Reusing an old indoor coil usually voids the rated performance and often the warranty, which is why most quotes replace both parts of the system together.
Do I need a permit for heat pump replacement in Bethlehem, PA?
In most jurisdictions this work is permitted and inspected. Requirements are set locally, so confirm the current application and inspection checklist with your building department before work starts.
How long does heat pump replacement take?
1-2 days of work, 1-3 weeks including permitting and inspection. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are system capacity in tons and the efficiency rating selected; whether the indoor air handler or coil is replaced with the outdoor unit; cold-climate (variable speed) versus single-stage equipment.
