An HVAC system consists of the appliances that handle your home’s heating and cooling, and it is one of the most important needs of any household. Your HVAC system is in charge of maintaining healthy indoor air quality and keeping you comfortable all year.

But how do you know whether your HVAC system needs to be replaced or if a simple repair will suffice? Learn how long a typical HVAC system should last, warning signs that it needs to be replaced, and other information about the HVAC unit.

How Long Does an HVAC System Last?

The HVAC system in a typical residential property should last between 10 to 25 years. However, the system’s lifespan depends on some factors, including:

  • The current HVAC system set up in your home
  • The amount of insulation
  • Maintenance Culture. Do you routinely service your air conditioning system?
  • Your local climate
  • Temperature preferences in your home

Most homeowners are unaware that a poorly insulated home reduces the lifespan of an HVAC system. If your home has cracks and gaps that allow air to leak in, your air conditioner or heat pump may be overworked.

How Often Should You Replace Your HVAC System?

Replace your HVAC system or select appliances in the system after ten years, based on the life expectancy of a typical heating and cooling system. Remember that if your air conditioner is well-maintained, it may last longer than the warranty period.

At the same time, you may need to replace your HVAC unit before it reaches the end of its useful life. Everything boils down to how well you maintain and service your air conditioning unit and heating system.

Signs Indicating Your HVAC System Needs Replacement

The System is Above 10 Years Old

When did you put your air conditioners in? Consider replacing them if they are ten years or older. Even if your air conditioner appears to be working properly, the unit may be struggling to keep up.

The most obvious reason for a replacement is an old and outdated HVAC system. HVAC technology is constantly evolving, and continuing to use an old AC unit may reduce your home’s energy efficiency.

Your Energy Bills Are Higher than Normal

Whether it’s the cooling costs in the summer or the heating costs in the winter, your HVAC unit probably needs to be replaced if you notice a consistent, significant increase in energy costs, indicating that the unit is no longer energy efficient.

The cost increase may be gradual and steady, but you could save money on frequent repairs and rising energy bills by installing a new HVAC system in your home.

Constant Repairs

The truth is that costly repairs frequently indicate that the AC unit is on its last legs. When an HVAC system reaches the end of its useful life, it may require more frequent repairs. If you find yourself constantly scheduling maintenance for your air conditioner, it may be time to replace it.

Perhaps you aren’t confident enough to purchase a new HVAC unit right away; you could stick to repairs until you have enough. However, if the repair cost is half or more of the cost of a new system, consider replacing it.

Inability to Maintain a Comfortable Temperature in Your Home

Reduced system efficiency is another significant indicator that HVAC replacement is required. If your unit struggles to keep a comfortable temperature in your space, you should consider replacing it.

When an HVAC system deteriorates, it no longer works as efficiently as it once did and can cost you a significant amount of money in energy bills.

Loud Noises or Odd Sounds from the HVAC Unit

If you’re familiar with the normal operational noises of your HVAC unit, you’ll notice that loud clanks and bangs aren’t among them. Perhaps your unit is constantly making unusual noises; replacing the entire system or broken appliances is the best option.

Odd noises almost always indicate serious mechanical problems that can be costly to repair. Consider purchasing a new heating and cooling system instead of repairing an old one.

Poor Air Quality

Your HVAC unit provides adequate ventilation, improves indoor air quality, and regulates humidity levels in addition to delivering cold and hot air into your home.

The HVAC unit improves air quality by filtering dust and allergens from the air in your space, so if you notice dust in your home, it’s most likely due to a faulty HVAC system.

Examine the air filters to see if they need to be cleaned or replaced. If the problem persists, your unit may be too old to operate at peak efficiency.

Regular Freon Top-Up

If your HVAC unit relies on freon to keep the air cool, it’s time to replace it. The R-22 freon refrigerant is harmful to the environment and is being phased out gradually, so it is not required in new HVAC systems.

Should You Repair or Change Your Air Conditioner?

If you’re still unsure what to do, hire a professional to conduct a thorough inspection. A certified HVAC expert is equipped to diagnose the problem with your HVAC unit.

Your technician will recommend the best and most cost-effective solution based on the diagnosis. Seeking professional advice can help you decide whether to repair or replace your HVAC system.

When Should I Replace My Air Conditioning System?

The off-season is ideal for scheduling HVAC unit replacements. It is not advisable to replace your old unit in the summer or winter.

The off-season includes the months of spring and fall, before the extreme cold or hot temperatures arrive. Given how busy HVAC contractors are during the summer and winter, it’s best to plan ahead for your HVAC replacement.
