Atlanta Air Conditioning Guide: Common Issues with AC Replacement

When you are replacing your Atlanta air conditioning system, it is imperative to have the right air conditioning company complete the project. The Atlanta AC specialists at Cool Air Mechanical are here to provide some great information on the most common issues with AC replacement.

Leakage in Return or Supply Ducts

Duct leakage is one of the leading causes of inefficiency in any new air conditioning system.

  • Return duct leakage decreases indoor air quality. Air from unused spaces, attics and crawlspaces mixes with the air in the ducts, potentially causing clogs in coils and the blower wheel which further decrease efficiency.
  • Supply duct leakage pushes air into unused spaces. This increases the AC run time, causing you to pay more for the same amount of cooling capacity.

When ductwork is properly installed and sealed it boosts energy-efficiency by as much as 15% to 20%, provides better air flow and a significant reduction in air contaminants.

Undersized Ductwork

Having a proper amount of air flow through ducts is imperative to overall AC performance.  When ducts are not large enough they restrict air flow, causing air conditioners to lose their full capacity of cooling. This leads to hot and cold spots.

Restrictive Registers and Return Grills

When return grills and registers are too small or an inadequate air filter is used it can decrease air flow. This reduces your air conditioning efficiency.  Proper sizing of return grills and registers as well as quality air filters will ensure the AC is gets the right amount of air.

Insufficient Refrigerant Charge

A low refrigerant charge can negatively affect AC performance by as much as 20%.  With the proper refrigerant charge an AC system should operate efficiently.

AC Sizing

Oversized AC equipment will cool a space but it cannot do so efficiently.  Undersized air conditioning systems will not properly cool an indoor space and will run almost continually to get the job done, causing higher energy costs.  With proper AC sizing your equipment will work efficiently.

Cool Air Mechanical can perform your Atlanta AC replacement correctly, ensuring that you never have to worry about these common issues. Call us today to learn more!
