An air conditioning system becomes less efficient over time, which translates to less comfort during hot and humid days as well as an increase in the average cost of your energy bills. If you believe that it is time to replace your AC, count on Superior Service to remove your old unit and install a new system. We have more than 50 years of experience in AC installation in St. Louis and St. Charles.


Our professional installation costs are affordable and competitive, and we offer many flexible financing options. More importantly, we save you money by getting the job done right the first time, because installing a new air conditioning unit is not an easy DIY job, and installing an AC system improperly may result in major damage (and energy costs). Attaching the wrong fan motor, for instance, could affect the machine’s ability to cool your house, meaning your unit has to work harder to deliver cool air to your household. This extra work means your cooling system is likely to break down sooner (and raise your utility bills in the meantime). Furthermore, improper installation could mean you void your unit’s warranty.

So, save yourself the trouble of HVAC installation. We’ll be more than happy to do it for you (and with transparent, upfront pricing for our labor costs).


When you ask us to install an air conditioner unit or a larger, full HVAC system, our Superior Comfort Specialists conduct a full home HVAC assessment and present a range of HVAC options to satisfy your air conditioning requirements. We also recommend top brands when you’re in the process of selecting an AC unit, so you can choose machinery that improves indoor air quality and has a high efficiency rating to lower your utility bills. Factors we consider include your budget, home size (square footage), your preexisting cooling and heating system, and whether you have an older home.

We walk you through the whole process, step by step, so that you can make educated decisions the entire time.

When is the Time for a New AC Unit or System?

The age of your HVAC system/air conditioning unit and its efficiency rating can help you determine if it’s time for a new unit.

Many conditioners installed just 10 or 20 years ago are considered energy inefficient by today’s standards, meaning that not only is your home not getting as comfortable as quickly as it could be, but you could be spending more money to do so.

Air conditioners in the United States use an energy efficiency system called SEER, which stands for “seasonal energy efficiency ratio.” A SEER rating tells you how effective an AC unit is and how much energy it needs to run annually; a higher SEER rating means the system is more energy efficient.

In St. Louis County today, the average minimum SEER rating of new air conditioners is 13. Just 10 years ago, many AC units only had a SEER rating of 10, and many systems installed over the past 20 years commonly operate at an 8 SEER rating or less. That means, if your home is running on an AC unit that is 10 or more years old, it could very well be time for an upgrade; a 13 SEER air conditioning system on average uses 18% less energy than a 10 SEER AC unit, meaning big savings for you!
