WALSH HEATING & COOLING - Falmouth's Reliable HVAC Services

Common signs include reduced cooling, ice forming on the coils or refrigerant lines, and a hissing sound. We start with a precise electronic leak detection test to find the source. After repairing the leak, we recover any remaining refrigerant, vacuum the system to remove moisture and air, and then recharge it with the exact manufacturer-specified amount. This ensures your system runs efficiently and protects the compressor from damage.

Leaky ducts force your system to work harder, leading to uneven temperatures, higher energy bills, and reduced indoor air quality as dust and allergens are pulled in. Our process involves a thorough inspection of your accessible ductwork, often using diagnostic tools to measure airflow loss. We then seal leaks at connections and seams with professional-grade mastic or metal-backed tape, which is more durable than standard duct tape. This repair improves comfort and can significantly lower your heating and cooling costs.

The best choice depends on the age of your system, repair frequency, and efficiency. If your system is over 10-15 years old, requires frequent repairs like recurring refrigerant leaks, or causes consistently high energy bills, a replacement is often more cost-effective in the long run. We provide a straightforward assessment, comparing the repair cost against the potential energy savings and improved reliability of a new, high-efficiency system designed for our local climate.
