McMullen Heating & Air Conditioning: Certified HVAC Repair Serving Langhorne 19047

If you're experiencing frequent boiler pressure drops, it's often due to leaks in the system or issues with the pressure relief valve. In Langhorne's older homes, this can be common. We recommend scheduling a diagnostic visit with our technicians, who will check for leaks, bleed radiators if needed, and ensure your expansion vessel is functioning properly to maintain stable pressure and efficient heating.

Signs of a refrigerant leak include reduced cooling, hissing sounds from the AC unit, ice on refrigerant lines, or higher energy bills. In Langhorne's humid climate, this can lead to discomfort and system strain. Don't just add refrigerant—this is a temporary fix. Our experts will locate the leak using electronic detectors, repair it, and recharge the system to EPA standards, restoring efficiency and preventing further damage.

We recommend biannual maintenance: in spring for your AC to check refrigerant levels and coils before summer heat, and in fall for your heating system to inspect boiler pressure and components. This proactive approach helps catch small problems like minor leaks or pressure fluctuations early, saving you from costly repairs and ensuring reliable performance through Langhorne's seasonal extremes.
