Preparing for AC Unit Installation in St Louis

Here are some options that you should consider when purchasing an air conditioner:

  • Properly Sizing the Equipment: Undersized equipment, ductwork, and refrigeration piping can affect the functionality of your air conditioner. Make sure the contractor you receive pricing from performs a full load calculation on your home. Hoffmann Brothers’ Project Managers perform a full load calculation at every estimate to take into effect all the windows and doors and the square footage of your home.
  • SEER Rating: Seasonal Energy Efficiency Ratio or SEER Rating is the efficiency rating of the air conditioner. The higher the SEER the more efficient the air conditioner and the lower your monthly bill will be. Hoffmann Brothers offers AC units rating in SEER ratings from a low of 13 to a high of 20 SEER on a standard air conditioning system. SEER ratings of older AC units are typically very low. Air conditioners wear out over time and have older technology. It is typical to find old AC units with SEER ratings of 6-10 SEER. By upgrading and replacing your air conditioner, our customers typically see a large reduction in utility costs as well.
  • Single vs. 2 Stage Air Conditioners: Air Conditioners are available in single stage or two stage units. Two stage air conditioners are more efficient (lower electric bill) and provide better humidity removal. If you plan on being in your house for more than 5-years we recommend a two stage AC unit.
  • Zoning Capabilities: Zoning systems are installed to even out hot and cold spots in a home. A two story home is a perfect application for zoning. A zoning system would allow you to have a thermostat for each story without having multiple systems. If zoning is something you are interested in, make sure to mention to your Project Manager.

Our certified technicians will discuss the options available to you and will make sure to apply any rebates, discounts, incentives, financing and tax credits to the final price.

Is Central AC Or Split AC Better?

A split AC system also runs at a high efficiency, which can save you money in energy savings in the long term.
