Chris is one of the best people I’ve ever met, he is loyal, kind and experienced! I will recommend SELIGA to family and friends.

Evelyn D.
Our technician Zeth was prompt, courteous and professional. Thoroughly explained what service was being performed and how much it would cost; upfront. Then after the service was performed went over everything again.

Lenny was very thorough and friendly.

I have been using your company since we bought our first home on Delor in 1967. We have had no problems with you service and you have some of the nicest people working for you in service and the office.

Marilyn V.
Clean, friendly, knew what he was doing and was able to talk to us and sort things out fast in a fast time frame even with an old and rusty equipment that I have.

Jesus S.
Very happy they always show up on time very honest co to have them service your equipment.

Richard Z.
Great experience! Seliga was able to squeeze us into their schedule the same morning when I called about an emergency A/C repair. The technician, Brett, arrived on-time and thoroughly explained the issue so that we could make an informed decision between a handful of repair options.

Mike K.
Guess I can't post multiple reviews. After 20 years my old ac kicked the bucket. Dropping substantial $$$ on appliances is never something I look forward to. That said Lawson H, Kiefer C. And John R. knocked out a full system replacement in a single day. Service is always top notch and the technicians give it to you straight.

Spencer A.
Seliga’s service is the best! Employees both in the office as well as technicians in my home are all a cut above! Brad B. and Mike I. Installed a new furnace today - very professional and efficient. I can highly recommend this company.

Ruth P.
Been with Seliga for Close to 40 years

Patricia H.
Just had a new central air system put in. I couldn't ask for a better company. Lawson and Kiefer were awesome. Kept me informed the whole time. Did an excellent job and cleaned up everything. I highly recommend Seliga!

hazel M.
Good customer service. Zach fixed my humidifier which no one else could and no extra charge while doing my maintenance.

Lee R.
Great service. Michael did a great job diagnosing my Mitsubishi mini split. He was happy to explain his trouble shooting process and answer my questions.

Bill H.
Had my yearly clean and check of my boiler/radiator system. On time, courteous, professional techs! (I have the spring/winter clean and check deal.) Great job!

Elaine P.
Very professional. The company sends a picture of the repair man 30 minutes before he comes so you can see what he looks like. They actually called and came early.

derek V.
Nate came out to see why our unit wasn't working. He did a great job keeping us informed of his progress. It wasn't an obvious issue but in no time, he figured out what the problem was. I would highly recommend Seliga for your HVAC systems. I hired them doing our yearly maintenance.

Rick R.
Unfortunately this is the second AC outage of the year but Seliga quickly responded, identified the issue, and repaired within an hour. I appreciate their techs straightforward handling and the fact that the repair didn’t require another visit in this heat wave. We will continue to use Seliga for all our needs. Thank you!

Kelly L.
Excellent service. Very thorough and honest. They are very prompt and give you plenty of notice about their arrival time for appointments. Great company!

Christopher S.
Seliga Heating and Cooling is always fabulous! Their service is always prompt, friendly, knowledgeable and professional. We recently needed our full system replaced, and they were exceptionally efficient and professional with the install. We are confident that we are set with our new system installed by Seliga! Thank you, Lawson H, Kiefer C, John R and Zeth O. You guys are so pleasant and do exceptional work! Happy to have a cool home again!

Jacqueline B.
I've used Seliga for mintenance inspections and always been satisfied. Lately Zeth has done my inspections and he is excellent. A few months ago I needed to install a new AC system and used Seliga and have been very happy with the results.

Jay U.
Krista came out today and was kind, knowledgeable, and thoroughly explained the system choices, as well as asking questions that would pinpoint areas that needed to be addressed, if any, for my mom whose AC had died in this heatwave. Dan(owner) had already penciled her in for installation this week so she is getting it far sooner than we anticipated! So happy to work with them all!

Diane B.
I called when having ac issues during a fairly hot period. The office was very friendly and scheduled a time to get someone out quickly. The technition, Zeth, was able to diagnose the issue and provide a recommendation quickly. He let me know what was going on as he was working and thoroughly explained all of my options for resolving the issues.

Andrew G.
Brett, Wayne and Christ that did the install of our new ac / heating unit where very professional, polite, and very tidy in there install. Both units are very nicely installed. These three definitely work well together.

Edward S.
I could go on all day but the bottom line is my first experience with Seliga was over the top from start to successful finish! 5 Stars aren't enough! They deserve 10-Plus Stars. They have earned my respect and will be my go-to company for all my future HVAC needs. Having spent the past 40 years in the home remodeling business-another service driven industry, Seliga is a company I will recommend to anyone needing help with their HVAC! My service tech, Lenny was very skilled and an absolute delightful human being! What a great guy! On the hottest day in St. Louis in 2 years they could not have done a better job! THANK YOU! BILL K
