Noisy. Inefficient. Frequently in need of repairs. An old HVAC system lets you know when it’s finally time for it to go. But is it worth keeping an HVAC unit around until it dies of old age? Or is a better idea to replace a unit before it has a chance to give up the ghost for good?

In spite of its upfront cost, new HVAC system can in fact improve your bottom line – substantially. Here’s how.


A New AC Unit Runs More Efficiently

A central air conditioning unit has a lifespan of about 20 years. But even when your AC is only half that old, you can still save 20 to 40 percent on your cooling energy costs by upgrading to a newer model.

Part of the reason why an older AC unit runs less efficiently is fouling by dirt and debris. Even with regular maintenance, a unit’s condenser coils can become dirty enough to use 40 percent more electricity while the unit itself loses about 30 percent of its cooling function. Inevitable wear and tear on the parts only does more to harm efficiency.

Newer AC units are also designed to run more efficiently than older models. As of 2022, every new AC unit sold in the U.S. must have a minimum Seasonal Energy Efficiency Rating (SEER) of 13. A newer unit’s resultant higher energy efficiency ratio will deliver appreciable savings when you pay your power bill!


A New Furnace Runs More Efficiently, Too

A well-maintained furnace can also have a lifespan of 20 years, yet it too loses efficiency as its parts gradually degenerate. And just as with AC units, furnace designs have become increasingly efficient over the decades as well.

A furnace’s Annual Fuel Utilization Efficiency (AFUE) rating reflects the percentage of heat generated for every dollar of fuel burned. The government mandated an AFUE rating of 78 percent in 1987, meaning that a furnace had to turn at least 78 percent of its fuel into serviceable heat.

As of 2015, the AFUE rating for a new furnace must be at least 80 percent. But if you opt for a top of the line model in 2022, you can find premium furnaces rated up to 98.5 percent. One of these would waste only 1.5 percent of fuel during combustion!


A New HVAC System Reduces the Need for Repairs

When your HVAC system receives regular and professional maintenance, it’s virtually guaranteed to run more efficiently. But it will also require fewer repairs, as your HVAC professional will detect and repair minor issues before they can devolve into much larger ones.

Unfortunately, there is only so much regular maintenance can do to conserve an HVAC system’s functionality. So long as they’re working toward keeping your home warm or cool, all of your HVAC system’s parts will wear down until they one day become inoperational.

HVAC repairs can be expensive. Replacing a component like an AC’s compressor or a furnace’s heat exchanger can cost upwards of $3,000. Granted, complete central air and furnace replacements are expensive as well – but to their benefit, they are predictable expenses.

By replacing an HVAC unit ahead of time, you can avoid an unexpected malfunction that will leave you without heat during the wintertime or cool air during the summer. You will also have fewer emergency repairs to worry about, which will enable you to budget for the future with greater confidence.


A New HVAC System Is Quieter

A new HVAC system’s superior efficiency comes with another great perk: quieter operation.

Admittedly, less furnace and AC noise will not improve your bottom line in any measurable way. But a modern HVAC system’s noise-reducing fan blades, variable speed fans and compressor insulation mounts can all help to reduce its operating noise to 50 to 60 decibels – about as quiet as a casual conversation. If you enjoy quietude as much as you enjoy saving money, then a new HVAC system represents the best investment you can make.
