I’m extremely pleased with my first experience with Comfort Specialists. Mike was available quickly to come clean and tuneup my AC. He was courteous and professional, explained his work clearly and showed me the results, and cleaned up after his work. I highly recommend him.

Michael from Comfort Specialists did an outstanding job. From the estimating and helping to select the right products, to the very professional installation. Everything in between as covered. Preparing the work area, working with the weather, meeting time frames and preparing for follow up in the spring. Michael works with professional licensed subcontractors that did not disappoint. Most importantly all was done with integrity and trust. Would 100% recommend and use again.
