A furnace is a long-term investment, and you want to choose one that wont let you down. Look for furnaces from reputable manufacturers that have a good track record of quality and reliability. Consider factors such as warranty length and customer reviews to determine if the furnace you're considering is likely to last for many years without needing frequent repairs.
The size of the furnace should be appropriate for the size of your home. A furnace that is too small will struggle to heat your home efficiently, while a furnace that is too large will waste energy and lead to higher energy bills. A professional HVAC technician can help you determine the appropriate size and heating capacity for your home.
One of the most important factors when selecting a new furnace is its energy efficiency. Look for a furnace with a high Annual Fuel Utilization Efficiency (AFUE) rating, which measures how much of the fuel consumed is actually converted into heat. A furnace with an AFUE rating of 90% or higher is considered energy-efficient.
The average lifespan of a furnace can vary depending on several factors, including the type of furnace, the frequency of maintenance, and the quality of the installation. On average, a gas furnace can last between 15 to 20 years.
Regular maintenance, such as changing the air filter, cleaning the furnace, and scheduling annual inspections, can extend the lifespan of a furnace. However, as a furnace ages, it may become less efficient and more prone to breakdowns, which could result in increased energy bills and repair costs.
In most cases, yes, your old air conditioning system should still work if you replace your furnace. The furnace and AC system are separate components of a home's HVAC system, and one can be replaced without affecting the other.
