TSI has done some maintenance and repair work on my A/C and furnace. They were very responsive and professional. Additionally when seeking quotes on possible additional services TSI staff has been very helpful in providing details and quotes for various options to help make an informed decision.
It was a hot and stormy night, most A/C stories probably begin this way, and ours went out. We called about 8 am and Jeff Corey with TSI had our A/C back up and running by 10:30 am. Amazing responsiveness, very thorough and professional service, and Jeff was a pleasure to work with on such a hot and humid morning. He was straightforward about the problem and did not try to up sell me anything unnecessary. We will definitely be using TSI to replace our A/C unit when it's time comes.
They did an excellent job. Great customer service.

A huge thank you to Tisha, Patrick and Luke at TSI. From the first phone call, to them pulling out of the drive after installing our new HVAC system, I was so grateful for their professionalism, knowledge, and kindness. They took the stress out of a very stressful day.
