You don’t need to become an HVAC expert.
Start with the questions that matter.
Heat pumps move heat between indoors and outdoors. In winter, they bring heat inside; in summer, they move it out. Ducted and ductless systems serve different home layouts.
Explore how heat pumps work ↗Moving heat can use less electricity than generating it with electric resistance. A heat pump also provides summer cooling. The right equipment and installation make a difference.
Explore heat pumps in Maine ↗Your insulation, existing heating fuel, electricity price, equipment efficiency, and usage all matter. Compare installation and operating costs before assuming a particular payback.

The important part is choosing and sizing a system for your home—and planning for the coldest days.
Read our Maine winter guide →Heating capacity and efficiency vary with temperature and model. Ask an installer for performance at your local winter design temperature and a room-by-room heat-load calculation.
Some systems can cover the full heating load; others need supplemental heat. Your home’s heat loss, room layout, and equipment determine the plan.
Include remote rooms, plumbing in unheated spaces, and outages in the conversation. A heat pump requires electricity, and many backup heating systems do too.
A little care goes a long way
Follow your manufacturer’s manual for your exact model.
These guides do not replace its instructions.
Simple habits help your heat pump do its job.
Efficiency Maine’s user tips ↗Follow the manual’s shutdown and filter-removal instructions. Vacuum, rinse, or replace filters only as specified for that filter type. Let washable filters dry fully before reinstalling. Do not spray water into the unit or electrical parts.
Follow the manufacturer’s schedule and check more often with heavy use, pets, or dust. Clean when visibly dirty or when the filter indicator appears. Some filters must be replaced rather than washed.
Maintain the clearances in the installation manual. Keep leaves, vegetation, and snow drifts away from airflow paths. Do not chip ice off coils. Persistent ice or a blocked fan needs professional attention.
Follow the manufacturer’s professional cleaning and service schedule. Contact a qualified technician for persistent leaks, unusual noise, reduced performance, or recurring faults. Coil deep-cleaning, refrigerant, and electrical work are professional tasks.
