您应该多久更换一次炉子过滤器？
typically 2-3 times per year, depending on how often you use your heating and cooling system, how dusty your home is, and if you have pets or not. a good rule of thumb is to change 1-2 inch filters every three months, 4 inch filters every six months and 5 inch filters every 12 months. if the filter is visibly dirty it's a good idea to change it. the more dense the dirt, the less efficient the system will be.
每年至少一次，但最好在春季和秋季各一次。建议使用此频率是因为加热和冷却系统有许多可能发生故障的部件。预防性维护可以延长系统的使用寿命。定期维护还有助于确保系统高效运行，从而减少水电费。最重要的是，如果您有煤气炉，确保系统中没有可能影响您健康的危险泄漏至关重要。热交换破裂并将一氧化碳释放到空气中的情况并不少见，这可能是致命的。
