Eastham Heating and Cooling Services
Cape Cod winters are milder than inland, but a house without heat is still a problem. And if you close your home for winter, proper preparation keeps everything protected.
GEM keeps Eastham homes comfortable with heating and cooling services designed for coastal living.
Air Conditioning
Central AC keeps your entire home comfortable through summer. When it works, you enjoy the season. When it fails before guests arrive, you need it fixed fast.
Coastal humidity makes AC work harder. Salt air can corrode components. Regular maintenance prevents most problems, and when something does fail, we get there fast.
- Air Conditioning Replacement: When AC equipment in your Eastham home struggles with humidity or runs constantly, a new system makes summer comfortable again.
- Air Conditioning Repair: When your Eastham AC blows warm air, makes strange sounds, or cycles constantly, we find the problem and fix it right.
- Air Conditioning Maintenance: Spring AC maintenance for Eastham homes is especially important for seasonal use. We make sure your system is ready when you arrive.
- Air Conditioning Installation: AC installation in Eastham means sizing systems for coastal conditions, ensuring effective cooling and reasonable energy costs.
Furnaces
Your furnace keeps your home livable through winter and protects pipes from freezing. It needs to work reliably, especially if you are not there to monitor it.
Gas furnaces serve many Eastham homes. Salt air and humidity can accelerate wear on components, making regular maintenance especially important.

Ductless Mini-Splits
Cape Cod cottages and older homes often lack ductwork. Ductless systems add heating and cooling without major construction.
Ductless mini-splits are popular in Eastham. They work well for seasonal homes, additions, and homes without existing ducts.
- Ductless Mini-Split Replacement: Ductless unit at your Eastham place getting noisy or not cooling well? New models are quieter and handle coastal humidity better.
- Ductless Mini-Split Repair: Ductless system in Eastham showing error codes or leaking? Salt air can cause issues. We service all brands and fix it right.

- Ductless Mini-Split Installation: Cape cottage without central ducts or a seasonal home that needs independent heating and cooling? Ductless installs without major work.
Heat Pumps
Heat pumps handle heating and cooling with one system. Cape Cod’s moderate climate makes them especially effective here.
Eastham’s weather is well-suited for heat pump performance. Milder winters mean efficient operation, and you get cooling in summer without separate equipment. As a Mass Save approved installer, we help you access rebates.
- Heat Pump Replacement: Eastham homeowners with aging heat pumps benefit from upgrading. Newer models offer better performance and improved efficiency.
- Heat Pump Repair: When your Eastham heat pump has refrigerant issues, compressor problems, or salt air corrosion, we diagnose and repair thoroughly.

HVAC FAQs
Can GEM service my home if I am not on Cape?
Yes. We work with many seasonal residents and can coordinate access for maintenance, repairs, and seasonal startup. Some homeowners add us to their contacts for when they are away.
Does salt air really affect HVAC equipment?
Absolutely. Coastal corrosion accelerates wear on outdoor units, coils, and electrical connections. Regular maintenance lets us catch problems early. We recommend protective treatments for new installations.
What should I do before closing my Eastham home for winter?
Proper winterization prevents frozen pipes and equipment damage. We can help with seasonal shutdown, including system protection and thermostat settings to prevent problems while you are away.
Are heat pumps a good choice for Cape Cod?
Excellent choice. The Outer Cape’s moderate climate is ideal for heat pump efficiency. You get heating and cooling from one system, and Mass Save rebates reduce installation costs.
Should I run my system before opening for summer?
Running equipment before heavy use helps identify problems when you have time to address them. Many seasonal residents schedule a spring startup so their home is ready when they arrive.
