Changing the HVAC air filter is a tenant responsibility per the 1836PM lease agreement. We’ve made it as easy as possible by partnering with Second Nature. If your home has HVAC, your air filter(s) will begin arriving on your doorstep shortly after you move-in. All you need to do is change it upon arrival and continue to do so each time a new one arrives approximately every 60 days, or as required by your HVAC system. No advance effort is required; we’ve got it covered! Should you have any filter installation or delivery questions please contact Second Nature at 1-800-308-1186, Mon – Fri, 10am to 6pm EST.
