Mini Split Not Working Right? Common Issues Explained: A KellerHomeowner's Guide

This topic comes up regularly across Keller, from Tarrant County to the rest of Tarrant County. Here's what's worth knowing if you're local.

For Keller Homeowners

Keller homeowners in Tarrant County deal with the same North Texas climate swings as anywhere else in our service area, and this topic tends to surface on the same seasonal schedule here as it does everywhere we work.

Keller, home to its own Keller ISD, has grown substantially over the past two decades, with newer subdivisions surrounding Keller Town Center and Bear Creek Park alongside older, more established neighborhoods. Newer homes here still benefit from a proper Manual J load calculation if a system is ever replaced, since a lot of production-built subdivisions were sized on assumptions rather than an actual calculation.

Keller 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.
