So, your outdoor HVAC unit has broken down, and your tech tells you the words that all homeowners dread – a replacement is needed. Unfortunately, even the most well-cared-for systems are going to shut down eventually, and while this is a costly investment, it’s something you want to make sure you do right.

Which leaves many asking… can I replace just the outdoor unit? Or does the entire HVAC system (both inside and outside) need to be replaced together?

The quick answer? If the outdoor unit is being replaced, the indoor one should be replaced right along with it.

We get why people question this. After all, why invest in something new if the old one is working just fine? Unfortunately, while it’s easy to think of your system as two separate parts, they actually work together a lot to ensure your home stays comfortable. And if they aren’t matched up, you’re going to experience problems.

Why would the old clash with the new? We’ve got more info below. And remember – if you need any assistance with your current HVAC system, please don’t hesitate to reach out to Airbusters team. We love ensuring Nashville residents are totally satisfied with their set-up!

Refrigerant Standards Have Changed

Back in the day, HVAC systems used a refrigerant called R-22. Yet, when new information was revealed about its negative impact on the ozone layer, it became officially banned in 2010. That said, people weren’t simply forced to replace their systems. Those with units that still required R-22 could continue utilizing it, but all new systems were made with R-410A, which is far better for the environment.

If your unit is on the older side, there’s a good chance it’s still using R-22. And if only the outdoor unit is replaced, your system will be functioning on two different types of refrigerants. This is a no-no, and in these cases, replacing both is a must.

Matching Systems Means Better Performance

The way HVAC systems are built, they’re meant to work as pairs. When installed together, performance is optimized, and you’ll experience increased efficiency and comfort. Units that don’t match will be less dependable, and both components will be forced to work harder, thus minimizing the lifespan of the entire system.

Essentially, the heating and cooling efficiency ratings that your unit is given will only be valid if it’s a matched system. If this isn’t the case, you’ll have an increased risk of damages and breakdowns, which will wind up costing you a lot in repairs. And your monthly energy bills? You can bet they’ll go up, too.

Technology Has Advanced

In the last couple of decades, we’ve seen a lot of advances in how well HVAC systems function. Today’s models are better at filtering out debris, they make less noise, they encourage better airflow, and they enable your system to run on less energy, saving you money in the long run.

If your outdoor unit is utilizing advanced technology while your indoor system is not, you simply won’t see those top-notch results you’re hoping for. If you’re going to invest in something better, you might as well reap all the benefits! Unfortunately this can’t be done without replacing it all.

Warranties Should Be Synced

If you replace only one unit without replacing the other, your warranties will no longer be aligned. Along with this, full warranty coverage may not be extended if the units do not match. If you ask us, it’s a lot more reassuring to know both units are covered by the same warranty for the same amount of time – it makes everything a lot easier to manage!

Saving More Money Overall

Initially it may seem like that the most affordable route to take is just replacing one unit instead of two. Yet, between an increased risk for damage, a lack of efficiency, and a likelihood of premature breakdowns, we assure you that you’ll wind up saving more money in the long run by doing it all at once. And your monthly bills will stay in check, too.

Not to mention, if your indoor unit is on the older side, it likely won’t be long before you’re forced to replace it anyway. Why pay installation fees now and then again in a few years when you can just get it all done at once?
