If they are well taken care of and maintained annually, most heating systems can last as long as fifteen to twenty years. At about the fifteen-year mark, however, you may want to start looking into new furnace installation in Seabrook, TX. You may be thinking, why would I start looking to replace my unit when it could still have another five years on it? Remember that as your furnace ages it loses efficiency, so a heater that is more fifteen years old could start driving up your monthly heating bill. Ideally, you should replace your furnace before it begins to give you trouble.
Perhaps you are already beyond that stage. If your heater is already acting up, and you find yourself facing costly repairs that amount to the price of a new furnace installation in Seabrook, TX (or more than 50% of a new furnace), then replacing it is your best option.
