Why Farmington Hills' winters and summers change how Heat Pump Installation should be planned
Farmington Hills' cold winters and humid summers change sizing and defrost needs for heat pump installation.

Which Heat Pump Installation option is right for Farmington Hills homes — and what permits are needed?
- Can I replace my gas furnace with a heat pump?
- Yes — a heat pump both heats and cools, so it can fully replace a gas furnace. In colder areas a dual-fuel setup keeps the furnace as backup for the coldest days. Either way, insist on a Manual J load calculation; conversions can need duct resizing or an electrical upgrade.
- When is replacing an old heat pump better than repairing it?
- If it's past 12–15 years, still uses phased-out R-410A refrigerant, needs a compressor, or the repair bill approaches a third of replacement cost, replacing usually wins. A reputable contractor compares both paths before recommending.
- Do Farmington Hills permits apply to heat pump replacements, or only to new installations?
- Permits generally apply to both major replacements and new installations in Farmington Hills when equipment size, electrical service, or refrigerant changes are involved. Homeowners should confirm permit responsibility with the contractor. Request the permit number and check with city offices if there is any uncertainty.
- What documentation should Farmington Hills homeowners get after installation?
- Homeowners should receive a final permit sign-off, the equipment warranty paperwork, a startup checklist, and a maintenance schedule. Also get written confirmation of refrigerant type and charge and any manufacturer dealer registration completed by the installer. Keep these documents for warranty claims and future resale disclosure.
