Report
Placed service call sun evening 8:20pm didn't receive response till 7:15 am Monday morning. I didn't expect someone to come out that night but did expect a return call that night. In my opinion that's bad service at best!

Very reasonable and professional. We have used Seliga Heating and Cooling for everything and the experience is top notch every time. From the people on the phones to the technicians who come to the house, we have never had anything to complain about. I love doing business with local family owned companies and this is one of my favorites.

Seliga H&C very generously helped my family get back into their home safely and quickly after the 12/2016 floods here in St. Louis. We are eternally grateful for everything the Seliga Team has done and donated on our behalf! Thank you - you guys are absolutely the best and we will never forget how well you treated us. I highly recommend calling these guys with any HVAC issues- they are the real deal and take pride in what they do. Mike and Family
