HVAC FAQs
Does GEM have experience with Marion’s older and waterfront homes?
Yes. We regularly service HVAC systems in historic properties and waterfront homes throughout Marion. Our technicians understand how salt air affects equipment and what older homes need.
How does coastal location affect HVAC equipment?
Salt air accelerates corrosion on outdoor units, coils, and electrical connections. Properties closer to Sippican Harbor face greater exposure. Regular maintenance catches problems early. We recommend protective coatings for new installations in Marion.
What efficiency improvements make sense for Marion homes?
Heat pumps offer significant efficiency gains and work well with our climate. Smart thermostats, duct sealing, and high-efficiency equipment all contribute to lower operating costs. Mass Save rebates help with upfront costs. We assess your home and recommend where investment yields the greatest benefit.
How should I approach an aging system that still works?
Consider operating costs, repair frequency, and how consistently it keeps you comfortable. Systems approaching 15 to 20 years often cost more to maintain than replace. We provide honest assessment of your situation.
What distinguishes GEM from other HVAC companies?
Family ownership means we answer for our work. We employ technicians directly rather than using subcontractors. When something goes wrong, you call us and we make it right.
