Top reasons to install a new air conditioner in St. Louis include:

  • Your system breaks down frequently: At Weis Comfort Systems, we promise to always do everything in our power to save your current AC system. However, there comes a point where your system requires so many repairs, it is more cost-efficient to install a new unit completely. Today’s cutting-edge cooling systems are designed to work better and last longer, and with our expert installation service, your new air conditioner will run for years to come. If you are constantly dealing with leaks, cycling, strange noises and smells, or airflow problems, do what’s best for your property, and call Weis Comfort Systems to install a new air conditioner today.
  • Your energy bills keep going up: If your energy bills keep rising as your air conditioner’s performance keeps declining, you will definitely want to look into getting a new system. Modern air conditioners are more energy-efficient than the models of the past, so you should be able to make up what you spent in lower cooling within a matter of years—or less! More importantly, high utility bills are almost always a sign that your AC unit is reaching the end of its lifespan, and that the problems your system is experiencing may not be able to be fixed.
  • You’re no longer getting the consistent cooling power you need: The bottom line is there comes a point in the lifespan of every AC system where it is no longer able to meet your home’s needs. This could happen because your family has grown, and you need more cooling power, or your system was not installed properly in the first place and has worn down sooner as a result, or you’re using a Freon-based system that’s already on its way out. But the bottom line is always that when your air conditioner stops providing the consistent cool air you need, it’s time to install a new one.
