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."

"Both the estimator Kevin the two installers who visited my home were very professional and kind. They answered all my questions and provided a very reasonable price for the installation of the attic insulation. I feel I was very informed on the federal rebate that was available for this installation, as well as on the recommendations of quantity of insulation I needed per residential standards and codes. I would recommend Anton and will use them in the future for my HVAC needs!"

Heating and air conditioning services FAQs

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
