Heat Pump Installation in Southern Maine — Built for Maine Winters
A properly installed cold-climate heat pump heats and cools your home for a fraction of the cost of oil, propane, or electric baseboard — even on the coldest Maine days. Southern Maine Mechanical installs right-sized, professionally commissioned heat pump systems across greater Portland, and as an authorized Efficiency Maine contractor we handle the rebate paperwork so you keep more money in your pocket.
Free In-Home Heat Pump Estimates & Load Calculations
Every install starts with a real load calculation — not a guess off square footage. We factor your insulation, windows, ceiling height, layout, and how you actually use each room to size the system correctly. Oversized heat pumps short-cycle and waste money; undersized ones can't keep up in January. We get the sizing right so your system runs efficiently and lasts.
Cold-Climate Heat Pumps That Perform Below Zero
We install cold-climate (hyper-heat) systems from Mitsubishi Electric, Bosch, Samsung, Daikin, and Fujitsu that are rated to deliver heat at temperatures well below zero. Whether you want a single-zone mini-split for one room or a multi-zone system for the whole house, we match the equipment to your home, your budget, and Maine's climate.
Efficiency Maine Rebates — We Handle the Paperwork
As an authorized Efficiency Maine contractor, we submit your rebate application for you. Most qualifying heat pump installations receive between $1,500 and $10,000 back, and many homeowners also qualify for federal tax credits. We'll tell you exactly what you qualify for before you commit — no surprises, no guesswork.
Professional Commissioning & Warranty Support
A heat pump is only as good as its installation. We pull permits, set line sets and condensate correctly, pull a proper vacuum, verify refrigerant charge, and commission the system to manufacturer spec. Every install includes manufacturer equipment warranties plus our own labor warranty, and we register your equipment for you.
