ᐅ Maintenance Contract for Residential Ventilation System, More Affordable Filters

Hello,
is it worth having a maintenance contract for a residential ventilation system? And what is a reasonable cost? I have five units in the apartment. Or can this be skipped by regularly replacing the filters myself? How often should the filters be changed, and are there more affordable filter options than those from the manufacturer?

Thanks for your help. Regards, Dani

I don’t have any experience with this yet, but the general consensus here is to do it yourself. Most people still seem to use the manufacturer’s filters, but apparently, you can also cut them yourself from larger sheets.

I've heard that as well. Thanks.

This is actually something you can do yourself without much trouble. Is it a centralized or decentralized system?

I have a centralized system. Every three months, I rinse the filters of the exhaust air valves once (this takes just two quick steps per valve) and vacuum the large filter in the central unit (which is simply pulled out). The large filter is then replaced once a year. The overall effort is minimal.

You can easily cut regular filters from mats yourself (except perhaps filter cartridges for the central system). This only costs a fraction.

Better to handle it yourself 🙂

Recently, the technician personally told me that although he would recommend the maintenance contract/extended warranty for the heat pump, he couldn’t recommend the same for the controlled residential ventilation system. Basically, it’s money down the drain.
