If you live in a climate with frigid winters and humid summers, then you know an HVAC system is necessary. But how should you decide when to replace your HVAC unit? There are some factors at play such as the condition of your current HVAC unit, the age of your HVAC unit, and the environmental needs of your home.

Due to wear and tear, existing systems will require replacing at some point in the future, but there is no reason to replace a system before it needs to be replaced. When your air conditioning unit or furnace breaks down more than it should, it is likely time for a replacement. There is no hard and fast rule for when a unit should be replaced.

1. Your HVAC System Is Old

If you have had your system for more than ten years, then there is a good chance that it is no longer working at its best. The lifespan of an HVAC unit can vary depending on the unit type, but it typically lasts around 10-12 years.

Technology keeps advancing, and equipment is now more reliable than just a few years ago. A system that is 10+ years old may not have the most efficient technology, and its parts may begin to break down.

Newer systems are energy efficient, and they require less energy to operate. Over time, an older and less efficient system will use more energy to keep the system cool and become less cost-efficient than a newer, more efficient one.

Older air conditioning systems used Freon, which R401A now replaces. The R401A refrigerant is a better choice since it is ozone friendly and offers better efficiency. Older units that use Freon negatively affect the ozone layer. Newer systems use variable speed technology to allow for greater efficiency. These units run at any speed needed to get the job done.

2. Your Energy Bills Are Higher Than Normal

If you have noticed that your energy bills are higher than normal, it is a sign that the system needs to be overhauled. This is because the system is not operating at the optimum level and is not as efficient as it could be.

A new HVAC system can help you reduce energy bills and save money. Newer systems are more energy-efficient, have better insulation, and use less electricity to operate than older models.

3. You Can’t Keep Your Home at a Comfortable Temperature

If you find that your home has trouble maintaining a comfortable temperature, then it is possible that the system is old, damaged, or not operating efficiently. Newer air conditioning systems can maintain the same temperatures with a lower set point, so you don’t have to use as much energy to cool your home.

Older systems have experienced wear over time and are not as efficient as they could be, so they struggle to maintain the ideal temperature. In contrast, newer systems are better at maintaining comfortable temperatures.

4. You Notice an Increase in Dust in Your Home

The insulation and ductwork can become damaged over time due to wear and tear. If you have noticed an increase in dust, then it is likely that your duct work needs replacing. It could be because of dirty or damaged air filters, leading to poor air quality.

This is mainly because the system is not ventilating and filtering the air properly. If you find this increasing, it could be time for a system overhaul. When the air filter is dirty, dust and debris can damage your HVAC system. The dust and debris are not suitable for your respiratory health either.

5. You Hear Odd Sounds and Loud Noises Coming From Your System

If your system is old and starting to break down, you may hear strange noises or vibrating noises coming from your unit. This might be because of a failing compressor or a faulty motor. It could be time for a replacement.

If you have an HVAC inspection, the technician will let you know if the system needs to be replaced. If you think you need to replace your system, you should get an HVAC inspection done so that your new system is installed correctly, and your home is safely cooled and heated.

6. Your HVAC System Needs Frequent Repairs

If you have discovered that your system needs frequent repairs, it is not performing correctly. The parts of an HVAC system are not cheap, so it can make financial sense to replace a system before it breaks down completely.

You may find that you are paying a lot of money to keep your current system running, which makes even more sense to get a new unit. Newer systems have more efficient technology and cost less to operate, saving money in the long run.

7. Your HVAC System Has a Major Breakdown

If your system has a major breakdown and it requires more than a small repair, it may be time to get a new unit. The system is unreliable, and you will pay more for repairs than a new system would cost.

You will have peace of mind knowing that the system is working properly when you replace it before it breaks down completely. The end of the warranty period indicates that it is time to replace the HVAC unit. When your warranty period runs out, your manufacturer no longer guarantees that they will repair your unit. Furthermore, they don’t guarantee that they will cover parts replacement costs.

8. Your HVAC System Is Running Continuously

It’s a good idea to check your unit at least once a month. If you have noticed that your unit is running continuously, then it is likely that the system needs to be changed out. Running costs are higher than usual if the air conditioning unit operates more often.

Newer systems are compatible with smart thermostats and remote-enabled devices, so you can control the temperature of each room throughout the day. They alert the user on the control panel if an issue must be investigated. They also have a weather forecast that helps the user set air conditioning to the correct temperature day and night.

Another benefit is that smart thermostats learn your patterns and can adjust the temperature to your needs. This helps as the unit will run when it is supposed to and ensure you get the best performance out of it.

9. Your House Is Being Renovated

If your home is being renovated, it makes sense to replace the HVAC system while the renovations are being done. Purchasing a new system will increase the home’s resale value and improve aesthetics.
