Weis Comfort Systems

Weis was able to send someone out the same day I called, which was good since it was in the mid 90s and my AC wasn't working at all! Rich was able to diagnose and fix my AC unit in under 30 minutes, getting our house back to being cool again. They were very upfront about pricing, which was very reasonable. Rich was very professional and courteous. I would certainly recommend them and will definitely give them a call next time I need service!

We have used Weis Comfort Systems for over 12 years for all of our heating and cooling needs, in two homes. They are always courteous, quick, honest, fair, and efficient! They just installed a new furnace and air conditioner last winter and we could not be happier! Fabulous company!

Weis was great as usual. I had forgotten the scheduled service until I received a quick phone call that Bill was on his way. No problem. Friendly and affable as always, he carried out his duties and pronounced everything 'okay.' This is a great company and watches my comfort all year long.

I have never written an online review before, but Weis's service was so bad that this is my first. For almost ten years I paid them to service my HVAC. I paid them to replace my HVAC, and once they did, my monthly utility bills doubled in the summer. Then I paid for service visits and even had a supervisor visit my home, and they told me they couldn't fix my problem.

Now, I have sold my house. I paid them over $400 for a pre-closing inspection and now get to pay an additional $500 to repair the very issue I begged them to solve for years. Fixing it would have saved me hundreds of dollars on my utility bills.

What a disappointment. I hope I can spare others by sharing this.

Great experience with Weis Comfort heating and cooling. I hired their St Louis office. Staff was very friendly and helpful. 2 hour service window was nice, compared to other hvac contractors wanting me to hang around all day. AC was fixed and running within 45 mins. Highly recommended to anyone looking for HVAC repair.

Weis just installed a new Daikin fit system for me with heatpump. The installers were fantastic! Exceptional quality, friendlyness and cleanliness. Definitely got what I paid for. Can't wait to see my electric bills drop. Thank you Weis!

Weis has been servicing our furnace and air conditioner for decades. Mostly the service calls are for regular maintenance. A few have been for repair. All calls were handled professionally. I can't remember having to call a second time because the problem was not corrected.
Weis also installed a new furnace and air conditioner during the mid 1990's. Again the company did an excellent job.

I have my heat pump serviced twice a year by Weis DeRousse and I always request Frank because he is the one who put the unit in years ago. I trust him to do a great job and he does. He is friendly and courteous. Jamie is very friendly always when I call the office.

The service personnel have been to my home several times since we moved to our new home in 2014. We were unfamiliar with geo-thermal and the people at Weis have explained the workings of the system and backup heat or cooling. Repair men are always courteous and professional. Good to have Weis for services.

A day after an appointment to fix the two-year-old A/C in my new home, the friendly folks at Weis notified me that the previous homeowners had purchased a 10-year parts/service warranty...and they had already refunded the repair fee for the work my unit had needed. Unexpected, and very welcome - they looked out for me when they didn't need to.
