Lancaster FAQ

Do mini splits need regular maintenance like central AC systems?+

Yes. The filters need regular cleaning (more often than a typical central-system filter, since they're smaller and see concentrated airflow), and the outdoor unit benefits from the same seasonal attention a central system's condenser gets.

Is it normal for a mini split to run constantly in extreme heat?+

Some increase in runtime during the hottest days is normal and expected, similar to any AC system. Constant running that isn't keeping up with the set temperature at all is worth having checked rather than assumed to just be the heat.

Does this apply to homes in Lancaster specifically?+

Yes. The guidance in this article applies to residential HVAC systems throughout Lancaster and the rest of our service area. If you want a read on your specific system, call us at (817) 935-8540 or request an estimate and mention you're in Lancaster.
