Furnace Replacement in Alpharetta
As a resident of Alpharetta, you're likely no stranger to the humid subtropical climate that dominates our region. With hot summers and mild winters, it's essential to have a reliable furnace that can keep your home comfortable year-round. Unfortunately, many homes in Alpharetta were built in the 1990s, which means they often feature older furnaces with efficiency ratings as low as 60-80%. This translates to higher heating costs and reduced comfort.
Modern high-efficiency furnaces have revolutionized the way we heat our homes. With AFUE ratings of 95-98%, these units can significantly reduce your heating bills, especially in a city like Alpharetta where rainfall averages over 40 inches per year. The high humidity during the summer months also puts additional strain on heating systems, making efficient furnaces even more crucial.
The cost of replacing an old furnace with a new one is relatively modest, ranging from $2,500 to $7,000. However, this cost can vary depending on factors such as furnace size, efficiency rating, and ductwork modifications. To ensure the job is done correctly and meets local building codes, homeowners should factor in permit and inspection fees. By investing in a high-efficiency furnace, you'll not only save money but also enjoy improved indoor air quality and reduced energy consumption – making your home more comfortable and environmentally friendly.
