HVAC Repair West Yarmouth MA | Call Sid Harvey

The combination of cold Cape Cod winters and wind-driven moisture can cause pipes to freeze, especially in exposed areas or poorly insulated systems. To prevent this, ensure all exposed refrigerant lines and condensate drains are properly insulated. During extreme cold snaps, keeping your system running at a consistent, low level can also help maintain steady temperatures and prevent freezing. Our team can help you select the right insulation materials and assess your system's vulnerability.

Common causes include a leak in the system (causing pressure drops), a faulty pressure relief valve, or issues with the expansion vessel (causing pressure spikes). The minerals in our local water can also contribute to sediment buildup, affecting pressure readings. It's important to have a professional diagnose the specific cause, as incorrect pressure can reduce efficiency and pose safety risks. We carry the replacement parts, like valves and gauges, needed for a proper repair.

For preparedness, we recommend having basic items like HVAC pipe insulation, a spare air filter, and a condensate pump switch on hand. For boilers, keeping an extra pressure relief valve and a set of seals or gaskets can be wise. However, for safety and proper function, we always advise consulting with our experts before attempting repairs on critical components like gas valves or control boards. We can help you build a sensible emergency kit tailored to your specific system.
