I received a call-back within 15 minutes of calling AtlasCare on a Saturday evening during a heatwave about a non-functioning a/c. Eric led me through a few things to try. Service was required however, and he was at my door in under one hour. He did a thorough inspection inside and out, replaced a part, tested and re-tested, and had his shoe booties at hand. I appreciated his explaining all work and findings since I am interested in knowing such things. Eric is a very pleasant young man who delivered a timely, and successful job. Part price included its installation labour and the diagnostics extended to all-around inspection inside and out.
