Furnace Replacement in Altadena
As a homeowner in Altadena, you're likely no stranger to the challenges of hot and dry summers. When it comes to heating your home during the fall and winter months, a reliable furnace is essential. However, many homes in this area are still equipped with aging furnaces from the 1940s and 1950s, which can lead to inefficient heating and increased energy bills.
The risk of furnace failure is particularly high in Altadena due to the extreme heatwaves that occur during the summer months. When temperatures soar above 115°F, the AC compressor can overheat, leading to costly repairs or even replacement. Additionally, the dry air can cause dust to clog filters and coils, further reducing a furnace's efficiency. Replacing an aging furnace with a new high-efficiency model can significantly reduce heating costs and minimize the risk of breakdowns.
With the median household income in Altadena at $129,123 and a median home value of $1,073,500, many homeowners may not realize that investing in a modern furnace is a worthwhile investment. A new furnace can achieve 95-98% efficiency compared to older models, which can pay for themselves through lower energy bills within just a few years. The cost range for a new furnace is between $2,500 and $7,000, depending on factors such as size, efficiency rating, and ductwork modifications.
