When It’s Time to Replace a Broken HVAC


When faced with extremely hot or cold temperatures, we always rely on our HVAC unit to save the day. We quickly change the thermostat to match our desired comfort level and enjoy some much-needed relief.

However, throughout consistent use, an HVAC unit will develop some issues. You might ignore minor signs because your system is still functioning correctly.

But you don’t want to deal with a broken HVAC when you need it the most. Rather than waiting for doomsday, here are nine signs it’s time to replace your AC.

1. Higher Energy Bills

Monthly energy bills are always fun to get in the mail (we’re kidding). You expect to pay higher energy bills in the blazing summer and freezing winter temperatures.

But during regular times, it still seems like you’re paying a hefty bill even though you maintain a specific home temperature. If you’ve noticed a gradual increase in energy costs, your AC unit might be the problem.

2. Your AC Unit is Dealing With Old Age

A well-maintained HVAC unit can last about 15 years, depending on factors such as:

  • Frequency of usage
  • Your location
  • Maintenance schedule

It might seem like your older unit is still working because there aren’t any problems. However, it will have to work twice as hard to meet your heating and cooling demands because of its old age.

Furthermore, your energy bills will likely increase due to your unit’s lack of efficiency. If you’ve had your unit for an excess of 15 years, it’s time to replace it.

3. Repairs are Getting Expensive

Having HVAC repairs are inevitable—many moving parts keep your system functioning correctly. But the more you repair your system, the more expensive it will be, especially if your HVAC unit is a little older.

Once your HVAC breaks down again, compare repair costs with installing a new unit. You may notice your home would be better off with a new system than fixing the old one. If so, you can find alternative air conditioners here.

4. Loud Noises are Coming from Your Unit

When you have an HVAC unit for a certain period, you’re very aware of how it starts up and turns off. However, there may come a time when you turn it on and start to hear weird sounds.

Loud clangs or a whistling noise mean your unit has an issue. If you catch the problem early enough, you may be able to repair it. But usually, these noises mean there’s a severe problem with your system, and replacement may be necessary.

5. Increase in Dust Around the Home

Heating and cooling aren’t the only components of your HVAC unit. The “V” stands for ventilation, which is significant for keeping your air quality clean.

If you notice more dust around your home, your unit isn’t filtering and ventilating as it should be. As a result, the increase in dust can affect those in your home that have respiratory issues or allergies.

Before replacing the unit, take a look a the air filter. Changing it could solve the problem. But if the issue persists after changing the filter, it’s time to get a new unit.

6. Inefficient Temperature Control

A sign that you have a broken AC is when there are constant temperature fluctuations throughout your home. It might not be clear as day but look out for issues such as:

  • Increased humidity in the summer
  • Difficulty keeping your home warm during the winter
  • Temperature variations in multiple rooms

The lack of efficiency can make for an uncomfortable home environment. Instead of repairing the unit, look at replacing it to enhance your home’s comfort without pressing issues.

7. There’s a Leak

Your air conditioners work the hardest during the summer, which is expected. So there will be a slight condensation build-up around your unit.

If you see a massive puddle of water around the AC, that’s the sign of a refrigerant leak. Furthermore, prolonged exposure to coolants can be hazardous to your family. You should contact an HVAC professional right away to avoid further issues with your unit.

8. Your Air Conditioner Still Uses R-22 Freon

Since January 1st, 2020, R-22 freon is no longer manufactured in the U.S. It may not seem like a big deal. However, if you have an HVAC system older than ten years, it will be a problem when your unit needs a refill.

R-22 was outlawed because of its harmful effects on the environment. Although you can’t purchase a new coolant of this nature, you can continue to service your HVAC system to maintain its efficiency.

But remember, the older your system is, the more costly repairs will be. So it might be in your best interest to install a new system that doesn’t use R-22 to create a healthier environment and keep your energy costs down.

9. You’ve Been on the Fence About System Replacement

Constant HVAC repairs can have you wanting to pull your hair out because of how much you’re spending. But you may also think installing a new unit is too expensive.

When faced with this problem, it’s always better to talk to a licensed HVAC technician. They’ll diagnose your system and tell you if you can continue repairing it or if replacement is inevitable.
