Old furnaces are far less efficient than new models.
If your furnace is older than 20 years old, you can expect 30%-50% of the heat produced goes right out the chimney.
This makes these furnaces quite expensive to operate compared to new equipment.
Older furnaces are also prone to more failures, requiring service by a licensed HVAC company at the most inconvenient times.
When a furnace gets to be 20 years old various different problems can begin to occur, sometimes causing a chain effect.
Gas valves become defective or break down, capacitors get weak and cause blower motors to break down.
So if you know your furnace may reach its demise in the near future, consider purchasing new technology- a Rheem furnace that will be reliable for years to come and saves you on an expensive gas bill. Call Metro Heating & Cooling at 651-294-7798
