Most HVAC systems have a lifespan of 10 to 12 years. So, if your AC is 8 or 9 years old when your furnace bites the dust, it's probably worth replacing the whole thing. Obviously, you don't want to spend money on a new unit when the old one still works, but it's worth remembering that replacing your HVAC system all at once can save significant time and money. As technology changes, replacing one system/unit while keeping others may not work as effectively as it should.

The quote, shopping, and installation processes take time. If you decide to replace a furnace and hold on to your aging AC, you'll likely be in the same spot a few years (or months) later. Upgrading your full HVAC system eliminates this second round of shopping.

Proactively replacing a system also saves you from spending money on repairs. Yes, it's usually possible to repair a unit, but if you're spending more than $1,000, it's probably not worth it. Frequent fixes add up; you'll save money in the long run by replacing your full system sooner rather than later.

It depends. Bigger is not always better, but you don't want an overworked system. You also can't assume that your existing equipment is the right size

-- there's no guarantee that the previous homeowners did their
homework as far as determining the best capacity for the house.
