Air Conditioner Installation in Chesterfield, Missouri

AC Installation and Replacement Services for St. Louis County Residents

Our summers in the Greater St. Louis Area can be long, warm, and humid. That means a reliable air conditioner is a must for your comfort. But nothing is built to last forever, and even the best, most efficient HVAC system will need to be replaced at some point, even with the best preventative maintenance and service agreement plan like ours.

If your air conditioning system's service life is ending, you don’t need to panic. Our team of heating, cooling, indoor air quality (IAQ), plumbing, and appliance repair experts at Chesterfield Service is here to offer you installation and replacement solutions in a timely and courteous manner. We’re here to walk you through the process and discuss which options would best suit the needs of your home according to its size and your budget. Our company is licensed, bonded, insured, and backed by decades of experience, and we give our customers access to flexible financing and convenient scheduling to make the process of getting a new air conditioner as seamless and stress-free as possible.

Air Conditioner Repair Vs. Replacement

In many situations, repairing your air conditioner can be more cost-effective than replacing it. But there are circumstances when replacing your system might be your best option. 

One reason is its age. The lifespan of an air conditioning system varies based on usage, maintenance, and the quality of the installation. Generally, a well-maintained air conditioner can last between 10 and 15 years. However, as it nears the end of its life, its efficiency can decrease, making replacement a more cost-effective and energy-efficient option. If your system is over 15 years old, it may be time to consider a replacement. Newer models operate more efficiently and are less likely to break down. 

It's also important to consider your current AC unit’s recent behavior. If your system requires frequent repairs, doesn’t cool your home evenly, or the cost of repairs is more than half the cost of a new system, it might be time to consider a replacement.

The team at Chesterfield Service is happy to help you determine if repair or replacement is best for you. We’ll evaluate your system and outline all of your options so that you know you’re making the right choice for your home and budget.

What to Expect During an Air Conditioner Installation

Our experts work hard to make the air conditioner installation process as smooth and stress-free as possible. Your satisfaction and safety are our main concerns, so you can trust our team will be courteous and meticulous when installing your new system. 

Our AC Installers use a detailed checklist that includes:

  • Assessment: Our process begins with assessing your space, factoring in the square footage of your home, insulation, and existing ductwork.
  • Sizing: We help homeowners select an appropriate size to meet their space's cooling requirements. This promotes efficient cooling without unnecessary energy consumption.
  • Preparation: Before installation, we check that your space is ready for a smooth installation, assessing electrical outlets and verifying proper ventilation.
  • Mounting: The outdoor unit, known as the condenser, is mounted in a suitable location where airflow is unrestricted and noise is minimal.
  • Connection: Electrical wiring and connections are handled with care for safe and reliable performance.
  • Installation of the indoor unit: The indoor unit is securely mounted, connected to ductwork (if applicable), and checked for proper condensation drainage.
  • Testing and calibration: Once installation is complete, the system is tested to ensure everything functions correctly. This includes checking for proper airflow, temperature control, and refrigerant levels.

Once completed, our AC installation professionals will guide you on the proper maintenance needed to protect your new cooling system’s performance, efficiency, and longevity. Throughout the installation process, we're mindful of your time and take the appropriate measures to install your system quickly and efficiently. 

The Importance of Professional Installation

You may be tempted to DIY your AC replacement, but hiring a professional is your best option for many reasons. Air conditioning replacement is a complex process requiring specialized knowledge and tools. You need training and experience to position and connect an air conditioner correctly. Choosing the right unit also isn’t as easy as it looks – size, efficiency ratings, and other vital factors can make the process overwhelming without professional guidance. 

Our professional installers can make sure that your new system is correctly sized and installed according to industry standards, maximizing its efficiency and lifespan. We have the expertise to handle all parts of the installation, from selecting the right system for your home to ensuring it’s properly integrated with your ductwork and electrical systems. With professional installation from Chesterfield Service, you can trust the job was done right the first time, saving you time and money in the long run.
