What Customers Are Saying

2014 we had advanced Chimney system install a gas insert for our fireplace. That experience went very well.

Today we had our 1st repairs to our fireplace.

I want to commend management for hiring such solid employees. Today Rex Randall completed installation of a new glass and thermostat control.

Great work and had the time to talk to Rex as he arrived early to his 10;30 appointment and completed work ahead of schedule.

Rex seems to be a fine young man and dedicated employee.

Rex said he's been with ACS since 2017 after given a chance to prove himself. Looks to me like he delivered

As I began, congrats to whomever at ACS hired Rex... He's a good hire.

We used the same chimney sweep for 20+ years, he retired so we called Advance Chimney Sweep. They arrived on time, were very pleasant and Hunter and Creech did a great job. Our chimney was cleaner than it has been in years. Extremely pleased with their services.

I wanted to thank James, Anthony, and Rex for a FANTASTIC JOB - WELL DONE!

We are very happy with the install and James and Rex did a wonderful job on the final fit and finish to get it installed correctly and looking good.

Thanks for providing a good looking unit to replace our old inefficient fireplace. Almost canâ€™t wait to be able to use it once the weather breaks!

Iâ€™m sure it will reduce my propane usage and keep our family room warmer than itâ€™s ever been.

We are very pleased with our gas log insert. The workmen were able to run the line without cutting the ceiling in the basement, which made it a much harder job. Everyone was very knowledgeable and helpful. We are thrilled and highly recommend Advanced Chimney Systems.
