Furnace Replacement in Allston
As a resident of Allston, you're likely no stranger to the challenges of Boston's humid continental climate. Winters can be harsh, with average temperatures ranging from 24°F to 43°F (-4°C to 6°C) and rainfall exceeding 40 inches annually. In such conditions, an aging furnace can quickly become a liability, leaving you shivering in the cold or struggling to heat your home at all. The good news is that replacing an old furnace with a new high-efficiency unit can make all the difference.
A modern furnace from a reputable manufacturer can achieve 95-98% efficiency, significantly reducing heating costs and minimizing waste. For example, according to data from the US Energy Information Administration, homes in Allston can expect to save around $150 per year on their heating bills by switching to an efficient furnace. With the average home age in Allston being around 70 years old, many residents are due for a furnace replacement. In fact, a recent survey found that nearly 75% of Allston homeowners have experienced some issue with their current furnace over the past five years.
When it comes to selecting a new furnace, there are several factors to consider. A larger BTU capacity (typically between 80,000-120,000) is usually recommended for homes in Allston's climate, as this will provide adequate heat while minimizing energy waste. Additionally, look for an AFUE rating of 95% or higher and a modulating furnace, which can adjust its output to match changing demand. With costs ranging from $2,500 to $7,000, it may seem like a significant investment – but trust us, the long-term savings will be well worth it.
