Common Causes & Easy Fixes for Sink Smells

Is It Time to Repair or Replace Your HVAC System?

Few things are more frustrating than a heating or cooling system that just won’t cooperate, especially during a Northern Indiana summer or a harsh South Bend winter. When your HVAC unit starts acting up, the big question becomes: Should you repair it or replace it entirely?

At Cavinder Plumbing, Heating and Cooling, we help homeowners in Granger, Mishawaka, Elkhart, and beyond make the most cost-effective and comfort-focused choice. Here’s how to know when it’s time to schedule a repair, and when it’s smarter to throw in the towel and invest in a new unit.

When a Repair Makes Sense

The System Is Under 10 Years Old
Most modern HVAC systems have a lifespan of 12–15 years. If your unit is still fairly young and has been well-maintained, repairs are usually worth it.
Repairs Are Minor and Infrequent
If the issue is a capacitor, thermostat, sensor, or another minor component—and this is your first repair in a while, it’s likely worth fixing.
Your Energy Bills Are Still Stable
If your utility costs haven’t spiked and your system is still relatively efficient, a repair can buy you more time without compromising performance.
You Plan to Move Soon
If you’re selling your home within the next year or two, a simple repair can keep the system functioning just long enough for the next owners to decide their own upgrade path.

When Replacement Is the Smarter Move

The 50% Rule
If the cost of the repair is more than 50% of the price of a new system, it’s usually smarter to replace. Newer systems offer better efficiency, updated technology, and full warranties.
Your Unit Is 12–15+ Years Old
Older systems tend to need more frequent repairs, run less efficiently, and may use outdated refrigerants like R-22 (which is no longer produced).
You’re Seeing Frequent Breakdowns
If you’ve had multiple service calls in the past few years, or worse, within a few months, it’s time to stop patching and start planning for replacement.
Your Energy Bills Are Rising
A system that runs inefficiently costs more to operate. Investing in a high-efficiency system can significantly lower your utility costs, especially with Indiana’s extreme temperatures.
Your Home Is Always Uncomfortable
Uneven temps, strange noises, or a system that constantly runs but never feels “right” are signs your HVAC can no longer meet your home’s needs.

Why This Matters for Northern Indiana Homeowners

In regions like South Bend, Granger, and Elkhart, HVAC systems have to handle humid summers and bone-chilling winters. That’s a lot of wear and tear, and it makes timing your replacement even more important.

A failing system can leave your home unprotected when you need heating or cooling the most. That’s why it’s smart to work with local experts who know the climate and can recommend the right system for your home's size, insulation, and airflow.
