What we do on a call

Redline is built around repair work. We get on site, put gauges on the system, check airflow and amperage, and identify the fault before anything comes apart.

If it is a dirty coil or a clogged filter, that is what we will tell you. Those two things cause a large share of the cooling complaints we see, and neither one needs a part.

When a component does need replacing, we show you the failed part and explain why it failed. You can decide with the equipment open.
