HVAC Installation in Southern Maine — New Systems Done Right
Replacing or installing a new HVAC system is one of the most significant investments you'll make in your home. Southern Maine Mechanical specializes in correctly sized, properly installed heating and cooling systems that are built for Maine's climate — and designed to last 15–25 years with proper maintenance.
Free In-Home HVAC System Estimates
Before recommending any system, we do a full load calculation — factoring your home's square footage, insulation levels, window count, ceiling height, and orientation. This is how we right-size a system. An oversized HVAC system short-cycles, wears out early, and fails to dehumidify. An undersized one runs constantly and can't keep up on the coldest days. We get it right the first time.
New Furnace, AC, Heat Pump & Boiler Installations
We install the full range of HVAC equipment: gas and propane furnaces, central air conditioners, cold-climate heat pumps, ductless mini-splits, hot water boilers, and combination systems. Whether you're replacing a failed system or upgrading an aging one, we'll match the right equipment to your home, budget, and fuel type.
Efficiency Maine Authorized HVAC Installer
As an authorized Efficiency Maine contractor, we handle all the paperwork for heat pump rebates on your behalf. Most qualifying installations receive between $1,500 and $10,000 back from Efficiency Maine — sometimes more when combined with federal tax credits. We'll tell you exactly what you qualify for before you commit to anything.
Installation Warranties & Post-Install Support
Every installation comes with manufacturer equipment warranties and our own labor warranty. We register your equipment, provide full operating instructions, and schedule a first-year checkup to make sure everything is performing as expected. You're not on your own after we leave.
