Kelly Air Conditioning and Heating: Best HVAC Repair Serving Philadelphia, PA 19114

In our historic Philly homes, a common culprit for dropping boiler pressure is a small leak in the system, often from aging expansion tanks, corroded pipes, or faulty pressure relief valves. Our technicians perform a thorough inspection to pinpoint the exact leak location and provide a lasting repair to restore safe, consistent pressure and heat.

High energy bills often stem from an inefficient system working overtime. Our comprehensive Philadelphia HVAC tune-up includes cleaning critical components, checking refrigerant levels, calibrating thermostats, and ensuring all parts are functioning optimally. This reduces strain on your system, improves efficiency by up to 15%, and directly translates to lower monthly utility costs.

If your boiler's pressure gauge is reading too high, the first step is to check the filling loop (if present) to ensure it's fully closed and not inadvertently adding water to the system. However, consistently high pressure can indicate a failed expansion vessel or a faulty pressure relief valve, which are safety issues. We recommend turning the system off and calling us for a prompt, expert diagnosis to prevent potential damage.
