Why AC Maintenance is Important

Most air conditioning equipment manufacturers recommend regular maintenance to ensure optimum performance of your air conditioning system. A tune-up helps to ensure that the components of your system are functioning properly and allows the technician to find small issues before they develop into bigger problems that can cause a major breakdown. Additionally, routine maintenance helps maximize performance and energy efficiency, summer after summer.

Complete Air Conditioning Tune Up

Our air conditioning tune-ups include much more than simply cleaning the air conditioner. We use a 25-point inspection to assess the performance of every aspect of your system to ensure that the air conditioner will get you through the summer. You can save time, money, and ensure that your home is comfortable in every season of the year by purchasing a service agreement that covers both your spring AC tune-up and your fall furnace tune-up.

If our technician discovers a problem with your system, we will communicate with you to explain the problem and recommend the best possible solution to meet your cooling needs. Should a repair be needed, we offer upfront pricing and discounts on new O'Fallon air conditioning installation.
