Your Trusted HVAC Professionals in the
Heart of Martha’s Vineyard

Historic homes in Edgartown require a careful balance. They need modern comfort systems that perform reliably without compromising architectural character. At Brennan & Co., we repair, install, and maintain the heating, cooling, plumbing, and indoor air quality systems, delivering efficient, dependable performance while preserving the details that make these properties unique.

From tree-lined streets to coastal-facing homes, Edgartown’s housing stock presents challenges that demand both technical know-how and a preservation-first mindset. Our team understands how to modernize your essential systems in a way that supports long-term comfort without disrupting the integrity of your home. We’re honored to have been chosen as Best HVAC Company by Martha’s Vineyard Magazine, and we back all of our work up with a strong warranty.

Responsive Service for the Edgartown Community

Problems with your home systems don’t respect standard business hours. That’s why we’re available 24/7 for emergencies. Even for less urgent situations, we still do everything possible to put you on the schedule for the same day you call. We bring over 20 years of experience to every call and are ready to work efficiently and responsibly to protect your home.

Reach out by calling (508) 905-4909 or by using our online contact form.

Upgrading Comfort While Preserving Character

In many Edgartown homes, heating systems are at the center of modernization efforts. Boiler upgrades and heating system improvements are often necessary to improve efficiency, reliability, and safety without altering the character of your house. We focus on delivering these upgrades in a way that integrates cleanly with existing structures, minimizing disruption while maximizing long-term performance.

Indoor air quality and humidity control are equally important in coastal historic homes. Moisture intrusion and seasonal humidity fluctuations can gradually affect woodwork, plaster, and finishes that are difficult to replace. By incorporating targeted air quality solutions, we help protect these materials while improving overall indoor comfort.

Cooling systems in older homes often need thoughtful retrofitting to maintain aesthetic integrity while delivering modern comfort. Similarly, plumbing upgrades must be handled carefully to support reliability without unnecessary structural impact. Every system we install or maintain is designed with both function and preservation in mind.

That means designing systems that enhance comfort and efficiency while respecting original materials, layouts, and craftsmanship. We aim to blend modern HVAC and plumbing performance with the traditional structures that define these homes, so upgrades feel seamless rather than intrusive.

Solving the "No-Duct" Dilemma in Whaling Captains' Homes

Traditional Edgartown homes often feature narrow hallways and original lath-and-plaster ceilings that cannot accommodate standard bulky ductwork. We offer "invisible" climate control solutions, such as small-duct high-velocity and floor-mounted mini-splits that mirror the appearance of traditional radiators.

These systems allow us to provide high-performance cooling and dehumidification without lowering ceiling heights or sacrificing the hand-carved millwork that defines your home’s interior.
