Eventually, every old furnace and air unit must be replaced by an air conditioning installation service with a new HVAC system. It’s a long-term decision, so you have to approach the issue of maintenance vs. replacement carefully. Here are points to remember when it’s time to upgrade your heating and air system.
Understanding New vs. Old Systems
The more an HVAC system ages, the less energy-efficient it becomes. Even if you bought the most state-of-the-art system 20 years ago, it's nowhere near as energy-efficient as a new system. If you have a furnace that's several decades old, it's a good idea to replace the air conditioner at the same time, so that both units have a long future ahead.
