Seasonal Care to Keep Your Cooling System in Optimal Condition

The best time to find a problem with your air conditioning system is before the Vineyard summer is in full swing, not after. Routine AC maintenance is one of the most cost-effective investments a homeowner can make, extending the life of your system, preserving efficiency, reducing the likelihood of unexpected breakdowns, and keeping your indoor air clean and healthy. Brennan & Co. has been providing professional HVAC maintenance to Martha's Vineyard homeowners and businesses since 2003, and our tune-up services are designed to cover every component that affects your system's performance and longevity.

Our fully trained technicians work on all major brands and bring the same meticulous attention to detail to maintenance visits as they do to full installations. Whether you're maintaining a year-round residence or preparing a seasonal property for summer, Brennan & Co.’s highly rated team makes it simple to stay ahead of issues and keep your home comfortable when it matters most.

A Thorough, Top-to-Bottom Assessment of Your Cooling System

A Brennan & Co. tune-up isn't a quick once-over; it's a comprehensive inspection, cleaning, and testing of every essential component in your cooling system. Our goal is to catch small issues before they become costly repairs, restore any lost efficiency, and give you a clear picture of your system's condition heading into the season.

Our AC tune-ups include:

Condenser coil cleaning. Dirty condenser coils force your system to work harder and run less efficiently. We clean them thoroughly to restore proper heat transfer and reduce strain on the compressor.
Air filter inspection and replacement. Clogged or degraded filters restrict airflow and degrade indoor air quality. We inspect your filters and replace them as needed to keep air moving cleanly through your system.
Refrigerant level check. Improper refrigerant levels, whether too high or too low, compromise cooling performance and can cause long-term damage. We check levels and address any irregularities we find.
Electrical component inspection. We inspect wiring, connections, and controls for signs of wear or failure that could affect performance or, left unaddressed, create safety concerns.
Thermostat calibration. An inaccurate thermostat leads to uneven comfort and wasted energy. We verify that your thermostat is reading and responding correctly to keep your system operating as intended.
Blower and airflow assessment. We evaluate airflow throughout the system to identify restrictions, imbalances, or mechanical issues that could reduce comfort or efficiency.

A well-maintained system runs more efficiently, lasts longer, and is far less likely to fail when you need it most, making routine tune-ups a small investment with significant long-term returns.

Pre-Season Maintenance for Seasonal Properties

Martha's Vineyard is home to a significant number of seasonal properties, and few things are more disruptive than arriving for the summer only to find your air conditioning system isn't up to the task. Systems that sit unused through the fall and winter are particularly vulnerable to the Island's salt air and humidity, which can cause corrosion, buildup, and component wear that goes unnoticed until the system is switched back on.

Brennan & Co. offers pre-season maintenance visits specifically designed for seasonal-use properties, giving your cooling system a thorough inspection and tune-up before you need it. We work around your schedule and arrival timeline so that your home is comfortable, your system is verified, and any concerns are addressed before the season begins, not during it. It's the kind of proactive, attentive service that Vineyard property owners have counted on from Brennan & Co. for over two decades.

Ready to get ahead of the season? Call (508) 905-4909 to request a same-day AC maintenance visit from Brennan & Co.!
