Seasonal Home Protection
Homes that are seasonal residences often sit closed for extended periods during the foggy shoulder seasons. Without active humidity management, the "closed-house effect" can trap salt-laden moisture indoors, leading to mildew on upholstery and damage to electronics by the time you return for the summer.
We can configure remote-monitored systems that allow you to check your home’s interior for grains of moisture from the mainland, providing a layer of security for your property even when you are off-island.
Take Control of Your Indoor Environment
If your home is showing signs of excess humidity, or you simply want to take a proactive approach, Brennan & Co. is here to help. As part of our commitment to long-term value, we offer a strong warranty, and we also help homeowners explore opportunities for energy efficiency incentives through programs like Mass Save.
Founded in 2003, we’ve won several Best HVAC Company honors, as chosen by Martha’s Vineyard Magazine, and we take pride in serving the unique heating and cooling needs of the entire community. Whether you're Up-Island or Down-Island, our local technicians are just a quick drive away.
