Quit searching! Corestar will provide the type of excellent service you’re looking for, one that I just experienced. From an initial urgent repair completed in a timely fashion by Josh, to an in home, no sales pressure consultation from Shaun and the impressive workmanship by Scott in replacing my 16yr old furnace, can only lead me to recommend Corestar.

We have used Corestar Mechanical for around 20 years now for a reason. They've provided outstanding products that have been hassle free, and consistently great service for ongoing maintenance and our recent furnace/AC replacement. They have been excellent to work with all around...highly recommend.
