It’s inevitable. Every air conditioner will eventually need to be replaced. How do you know when it’s time? AC units are often a significant expense, so you don’t want to replace them prematurely. In this blog post, we’ll discuss the signs that indicate your AC unit needs to be replaced.

We’ll also talk about how seasonal changes can affect your AC and what you can do to prolong its life.

What Factors Determine When it’s Time to Change Your AC Unit?

In the summertime, the temperatures are rising, and chances are you’re using your AC to keep cool. In the winter, your unit switches to heat mode. But did you know that AC units work all year round? Your AC unit works 24/365 to remove humidity from your home. Over time, this takes a toll on the AC unit, and it will eventually need to be replaced. But what happens when your AC unit starts to give you problems? How do you know when it’s time to replace it?

Here are a few factors that will help you determine when it’s time for a new AC unit:

  • The age of your AC unit – AC units typically last about 15 years. If your AC unit is older than 15 years, it’s probably time to start thinking about replacing it.
  • The AC unit’s efficiency – AC units over a few years old are less efficient than newer models. If you notice your AC unit is running more often than it used to or your energy bills are going up, it could be time for a new AC unit.
  • The AC unit’s capacity – AC units have a limited capacity. Over time, the AC unit will lose its ability to cool your home as effectively as it did when it was new. If you notice your AC unit isn’t cooling your home as well as it used to, it could be time for a new one.
  • AC units that require frequent repairs – AC units will need to be repaired from time to time. But if you have to fix your AC unit more often, it’s probably time to replace it.

If your AC unit shows any of these signs, it’s probably time to replace it. AC units are a significant expense, but they are essential to keeping your home comfortable.

How does Seasonal Maintenance Affect Your Air Conditioning Unit?

AC units are affected by the seasons just like any other appliance in your home. In the winter, your AC unit has to work harder to keep your home warm. This can put a strain on the AC unit and shorten its lifespan. In the summer, your AC unit has to work harder to keep your home cool. This can also strain the AC unit and shorten its lifespan. Having your air conditioner serviced regularly is critical to keep it running efficiently. Seasonal HVAC maintenance is beneficial in a variety of ways. Allow a professional to check your safety settings, change the operating pressure and thermostat settings, clean condensate drains, and do airflow measurements during their annual checkup. You can ensure that your unit runs smoothly all year long by coming in and checking off a few seasonal HVAC maintenance tasks.

Here is a helpful checklist of things to do each season:

Fall Maintenance Checklist

By completing these quick and easy HVAC maintenance tasks at the beginning of fall, you’ll enjoy a more efficient system all season long.

  • Instead of depending on the heater, use your windows to let in natural light.
  • You should turn ceiling fans clockwise to distribute heat from the top of the room to the living areas.
  • Keep the fan setting at its lowest possible speed to avoid a chilly wind.
  • Use safe space heaters to keep your home as comfortable as possible, and use a humidifier.
  • Replace air filters every month.

Spring Maintenance Checklist

Although spring is typically mild, the weather can get hot intermittently. So rather than automatically turning on your air conditioner, follow these tips to make your home more comfortable and keep your HVAC system in good shape.

  • Close the drapes, so the sun’s heat doesn’t bake your home. (It reduces indoor temperatures.)
  • Instead, use a ceiling fan.
  • Use a dehumidifier. Your house will be more pleasant at higher temperatures with less moisture.
  • Open windows to let in cool air drafts.
  • Clean your ductwork thoroughly.
  • Replace your air filters.

Summer Maintenance Tasks

There’s no getting around having your AC on in the summer. However, such reliance puts a load on your HVAC system. To help lighten the burden, use these summer seasonal maintenance activities to your advantage.

  • Upgrading your insulation will help to keep hot air out of your home and reduce the strain on your AC unit.
  • Regularly check drain pans for moisture, and run fans instead of the AC on temperate days.
  • If you’ll be gone from home for an extended period, turn off the AC, but not if you have pets.
  • Before using your AC unit for the first time each year, remove any debris that might have accumulated around it.
  • Don’t forget about those HVAC filters.

Other Signs That Your Air Conditioning Unit Needs Replacement

In addition to the AC unit being affected by the seasons, other signs indicate it’s time for a replacement.

  • Excessive noise or vibrations – anything like squealing, grinding, or grating sounds can indicate that your AC unit is on its last leg.
  • Leaking refrigerant – this can signal that your AC unit is low on Freon, which is used to cool the air.
  • Leaks – a technician should address any type of fluid leak immediately as it could be a sign of a bigger problem.
  • Bad smells – if your AC unit emits musty or burning odors, it’s time to call a professional. These could indicate moisture buildup or a wiring issue.

    I appreciate that you said that if an air conditioner is more than 15 years old, it should be replaced. Since my mother has had the same air conditioner since we were children, I believe replacing it would be preferable so that we could choose an energy-efficient unit. I’ll be sure to let her know about this and look into AC services that could help us with the new unit.
