Vitt Heating & Air Conditioning Co Inc

Family owned and operated company since 1954. Quality workmanship is one of our best qualities. Excellent customer service. With over 50 years of experience in the HVAC industry, we are confident we will meet and exceed your expectations. Our quality and attention to detail are unrivaled by the competition. We have served the residents of St. Louis with three generations of Vitts, and are raising the fourth. Our longevity is a testimony to our service and clients' trust. We have an excellent rating with the BBB and are N.A.T.E. Certified technicians. One major difference and benefit of our company is custom duct fittings. Custom fittings give your unit a longer, more reliable shelf life and a professional looking installation. Just ask to see our before and after pictures and you'll see the Vitt difference! Also, NONE of our employees are paid on commission, and do not get bonuses based on sales. What does that mean? That guarantees that we will not try selling you something you do not need. Only if your system is non-repairable, or at your request will we suggest purchasing a new system. We will not have a "salesman" show up at your door whose main objective is to sell you something. We are there to make you happy and comfortable, that's it. NO SUBS. CHARGES BY THE HOUR. NO TRAVEL CHARGES. ADDITIONAL CHARGE FOR AFTER- HOURS SERVICE MAY APPLY

Hi Mrs. [Member Name Removed], thank you so much for your review! I am very glad that you enjoyed your experience with our company! :-)


I have been using Williams Heating & Cooling for 3-4 years now, mostly for regular HVAC maintenance checks, although once I did have a semi-emergency. They were able to come by my house the next day and do the repair to help ease my mind. I usually have the same technician perform the services and he is always friendly and professional. As of now I plan to keep using them for any future HVAC needs...

They gave me one of the best quotes, and responded to my inquiries very quickly. They were amazingly professional and completed the work when they said they would. They even helped me find another professional to install the security cage I needed as they didn't offer that service. They vouched for him and he was equally professional.

I had an A/C condenser that was acting iffy. I had another company come take a look. The A/C was running at the time and they couldn't find the problem. But then the A/C acted up again, and I called Williams Heating & Cooling. A technician came out the next day, found the problem and fixed it in just about 1/2 hour. Very impressed. Not all companies deliver the same quality of service even if they...
