Accurate Diagnoses, Lasting Repairs

Air conditioning problems rarely announce themselves clearly. A struggling system can have any number of underlying causes, and addressing the symptom without identifying the source only leads to repeated failures.

Brennan & Co. takes a thorough, diagnostic-first approach to every repair, making sure we understand exactly what's driving the problem before we resolve it. Our technicians are experienced with the full range of issues that affect cooling systems on Martha's Vineyard, including the accelerated wear that salt air and coastal humidity can cause over time.

Common AC problems we diagnose and repair include:

Insufficient cooling. When your system runs but can't reach or maintain your set temperature, the cause may be low refrigerant, a dirty evaporator coil, or an undersized or improperly configured system, all of which we can assess and address.
Warm air from vents. This is often a sign of a refrigerant leak, a failed compressor, or restricted airflow, each requiring a different repair approach that our technicians can identify on the spot.
Short cycling. A system that turns on and off too frequently may be dealing with an oversized unit, a failing thermostat, or electrical issues, problems that strain your equipment and drive up energy costs if left unresolved.
Unusual noises or odors. Grinding, rattling, or musty smells can indicate mechanical wear, loose components, or mold growth in the ductwork or coil, issues that are best caught and corrected early.
Poor airflow. Weak or uneven airflow throughout your home is commonly caused by blocked filters, damaged ductwork, or a failing blower motor, all of which affect both comfort and efficiency.

No matter how the problem presents, we work to restore full performance, minimize energy waste, and extend the life of your system, not just get it running again.
