Silva Dwight D Hvac: Professional HVAC Repair Serving Hyannis, MA 02601

Low boiler pressure is a common issue in our area, often caused by minor leaks in the system or a faulty pressure relief valve. This drop prevents hot water from circulating properly to all your radiators, leading to those frustrating cold spots. We can perform a thorough inspection to pinpoint the exact cause—whether it’s in the boiler itself, the pipes, or a radiator—and make the necessary repair to restore even, reliable heat throughout your home.

An imbalanced radiator system usually means some radiators get too hot while others stay cool. This is often due to trapped air, sludge buildup in older pipes, or incorrect valve settings. We start by bleeding your radiators to remove air, then assess the system flow. For persistent issues, a power flush may be needed to clear out corrosion and debris. We'll balance the valves to ensure heat is distributed evenly from room to room, eliminating those uncomfortable temperature swings.

We recommend an annual service for both your heating and cooling systems. Our coastal salt air can accelerate corrosion on outdoor AC units and heat pump components, while our heating systems work hard through long winters. A yearly tune-up by our technicians includes checking pressure levels, cleaning critical components, testing safety controls, and catching small issues—like a minor pressure leak—before they turn into a major repair or a cold house. It’s the best way to ensure efficiency, safety, and year-round comfort.
