Air Conditioner Replacement in St. Johns, FL

Service Request

Reliable Ducts can help you find a reliable air conditioner replacement in St. Johns, FL. Our AC technicians have a lot of experience with installing AC units and can help you figure out what upgrades you need. For example, some people will benefit significantly from geofencing technology. This technology allows the AC unit to automatically turn on or off based on your proximity to your home. If you’re someone who always forgets to turn the AC off, you’ll never have to worry about it again. Your wallet will thank you too!

One of the main things to consider when looking at an AC replacement in St. Johns is the capacity of the unit and its ability to cool down the intended volume of space. The capacity of AC units is measured in British Thermal Units (BTUs), and BTUs can vary significantly from 5,000 to over 14,000. In general, we recommend having 20 BTU for each square feet of space. You should also look at the energy efficiency rating of the unit to get a better idea of its overall performance.

When to Get an AC Replacement

Our team will walk you through the entire air conditioner replacement process, so you make the most informed decision possible. We can compare and contrast different brands, models and types to work within your budget. We can even help you transition from one type to another. Popular types include portable, window, central AC systems and ductless mini-split units.

Most AC units will start to break down when they reach 10 years old. Units over 10 years of age are considered older and usually don’t have as many energy-efficient components. If you have an older unit, we highly recommend that you consider getting a replacement if you notice the following:
  • An increasingly frequent need for repairs
  • Constant breakdown of unit
  • Increasing repair costs
  • Difficulties turning unit on or off
  • Rising costs of energy bills

    • “We live at the beach and had new AC installed but still could not figure out a way of keeping the humidity down. Reliable Ducts took several hours just to diagnose the issue and come up with a solution that was tailored to our needs and our budget. The installation was timely and professional as well as clean and fairly priced. We installed a whole house dehumidifier, ultra violet light to maintain mold free air and added vents to create air movement. It all works perfectly now. Thank you!”
