Common signs include the pressure gauge reading too high or too low, frequent need to repressurize the system, unusual noises like kettling or banging, and radiators that aren't heating evenly. Low pressure often indicates a leak, while high pressure can be a sign of a faulty pressure relief valve or expansion vessel issue. If you notice these signs, it's best to call a professional for diagnosis to prevent further damage.

For most Ronkonkoma homes, we recommend checking your filter monthly and replacing standard 1-inch filters every 1-3 months. During high-use seasons like summer and winter, or if you have pets or allergies, you may need to change it more frequently. A clogged filter forces your system to work harder, reducing efficiency, increasing energy bills, and potentially causing overheating or freeze-ups.

Absolutely. Beyond reduced airflow, a severely clogged filter is a primary cause of system failures. It can lead to frozen evaporator coils in your AC, overheating in your furnace's heat exchanger, and excessive strain on the blower motor. These issues not only cause discomfort but can lead to costly repairs. Regular filter changes are the simplest, most effective maintenance you can do to protect your HVAC investment.
