Should I Repair or Replace My Furnace?
While no one can predict exactly when your furnace will go out, there are a few clues that a furnace needs to be replaced.
How Old Your Furnace Is
Increased Energy Bills
Worn down furnaces won’t be as efficient. If yours hasn’t undergone preventative furnace maintenance, you risk losing further furnace efficiency and dealing with steeper energy costs.
Frequent Repairs
You should think about replacing your furnace if yours need repairs more consistently.
Spotty Heating
Three Benefits of a New Furnace
While furnace installation can feel intimidating, new furnaces include new features worn down systems can’t compete with. In addition, you’ll be able to relax knowing you won’t have to replace your system for years to come.
A new furnace should provide:
Improved Efficiency
Todays furnaces are very resilient and offer higher efficiency ratings versus systems from 20 years ago.
Quieter Operation
A newer furnace includes the latest in quiet operation technology. You won’t always notice when it starts running.
Peace of Mind
Modern HVAC technology ensures your heating will last longer and run with increased energy efficiency. With our service agreements, you’ll never lose out on an important annual tune-up again.
