Geothermal Energy
Geothermal energy has been gaining popularity as an eco-friendly way to heat and cool a home at a fraction of the cost of fuel-burning systems or even conventional air-source heat pumps.
Geothermal HVAC, also known as ground-source heat pumps, is an eco-friendly and cost-effective way to heat and cool your home by harnessing the stable temperatures found underground. By using the earth as a heat source in winter and a heat sink in summer, geothermal systems can provide highly efficient, reliable comfort year-round. Our technicians are fully trained and knowledgeable and available to answer any questions you may have about switching to Geothermal. You can also check out the FAQ page for more info.

Camp Spring Start‑Up & Winterization Services
At Northern Temp LLC, we help camp and seasonal homeowners throughout Maine protect their property and prepare for every season. Our Spring Start‑Up and Winterization Services are designed to safeguard your investment, prevent costly damage, and ensure your systems are ready when you arrive — or secure when you leave.
Winterization
Before freezing temperatures set in, our technicians perform a complete shutdown and protection of your property’s plumbing, water, and HVAC systems. We drain and blow out all water lines, protect traps and fixtures with antifreeze, and secure pumps, tanks, and equipment to prevent freeze damage. Each system is tagged and documented, with photos and a detailed report for your records. We also inspect your heating and cooling equipment, verify mini‑splits are in proper winter mode, and check for leaks or electrical concerns before locking up your camp for the season.
Spring Start‑Up
When warmer weather returns, we reverse the process to bring your camp back online safely and efficiently. Our team reconnects hoses, sprayers, and fixtures, primes pumps, fills and tests the domestic water system, and restores power to water heaters and HVAC equipment. We inspect for any freeze damage, test all plumbing and heating systems, and verify proper operation of your mini‑splits, thermostats, and water treatment systems. You’ll receive a full report with photos and recommendations for any needed repairs or maintenance.
With Northern Temp LLC, you can trust that your camp is cared for by professionals who treat your property like their own — ensuring comfort, reliability, and peace of mind all year long.
