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

"I'd give zero stars if I could. Made an appt for 12:00-4:00 with me getting a call from the tech Coll Mcminn around 3:47 saying he was on his way and will be 35 minutes. He said that before he comes out it would be $125 just to come out and then another $275 to diagnose the leak in my system. So $400 just to find the problem. As we continued talking I got the feeling like he was just done for the day and was trying to talk me in to getting a quote for a new system so he wouldn't have to come out. I told him the system is 15 years old which isn't that old but he said it was probably in the coils which would require replacing half the system anyway. I only called them because they moved my AC line a few years back and was thinking it possible that they didn't do that properly to begin with which could be the source of the leak. The PVC work that they did was faulty and they had to come back to fix that. Not a great company if you ask me."

Central a/c installations FAQs

If you’re replacing an old AC system with a new unit, you can usually clean and repair the old ductwork without having to conduct a full replacement. Cleaning HVAC ducts typically costs around $400, while repairs range from $200 to $1,000. In contrast, installing new ductwork can range from $1,000 to $5,000, making it far more costly than cleaning or fixing existing ducts. HVAC installation costs an average of $7,000 to replace a full system, so staying on top of maintenance and repairs is important.

AC cost efficiency depends on the size of your space and your long-term plans for your home. If you only need to cool a small area, a portable AC unit has a low upfront cost. Heat pumps are typically the most cost-effective option if you want to cool an entire home or improve the resale value. They provide strong cooling while being energy-efficient, which saves you money on your utility bills compared to most other AC types.

Installing a central AC unit typically takes four to eight hours if your home already has ductwork in place. However, if new ductwork needs to be installed, this can add another one to two days of labor to your project.
