An HVAC system's average lifespan is between 10 to 15 years, but it still depends on how you take care of your heating and cooling units. Since your HVAC system runs day and night, it makes it one of the essential systems in your house. And it could be one of the most expensive units in the house as well. So, to maximize your investment in purchasing an HVAC system, follow these tips.

Regular Maintenance
If you want your HVAC system to maximize its working life, you must perform regular maintenance. A professional HVAC technician should conduct scheduled HVAC service to ensure that all the parts are thoroughly inspected. Routine maintenance includes lubrication of moving parts, checking refrigerant levels, condenser cleaning, clearing build-up in the condensate drain tube, replacing filters, and other tasks that need to be carried out for a tip-top shape HVAC system.

Change the filter regularly.
This task should be simple and can usually be done by the homeowners. Although changing filters are easy, it plays an important part in prolonging your HVAC system's lifespan. When the air filter is dirty, the HVAC system needs to work harder to circulate the air inside the house. That's why the air filter should be changed frequently based on its recommended lifespan. Typical air filters are disposable 30-day fiberglass or 3-month pleated filters. However, if the air filters are too dirty, you change it even ahead of its schedule.

Use the "auto" fan setting.
The auto fan setting makes the fan run only if the HVAC system is actively cooling or heating the area. On the other hand, when you select the "on" fan setting, the fan will continuously work which makes the system work harder and eventually break down. Although the "on" fan setting is often beneficial for people who have allergies or respiratory sensitivities, this fan setting can be taxing your system.

Inspect the condenser
The condenser unit of your HVAC system is usually placed outside of your house. The condenser is built to withstand different outdoor elements and adverse weather conditions. However, always make sure that there is no obstruction or accumulation of debris or dirt in your condenser unit, especially after a storm. You have to ensure that your condenser unit is correctly working to avoid any further damage to the other parts of the HVAC system.

Upgrade your house's insulation
If you want your house to keep the cold or warm air inside, you must check the insulation inside of your home. If your house is well insulated, the use of your HVAC system will be lesser than usual. As a result, it will help prolong the lifespan of your HVAC system. The most common place to upgrade or add insulation is in the attic. You may check the Environmental Protection Agency's recommendation for the proper insulation guidelines or schedule a heating and air repair service to a professional technician for a proper inspection.

Upgrade your thermostat
If you are still using the manual thermostat, you might consider upgrading it to a smart thermostat. A smart thermostat can be controlled from anywhere using a smartphone or a tablet. It can even save your HVAC habits and will automatically adjust the settings for more energy-saving consumption. In this way, you can maximize your HVAC system's usage, making it last for a longer time.

Even a well-maintained HVAC system will come to an end. And before your current HVAC system shuts down, you have to purchase a new one. But when is it the right time to buy a new HVAC system? Here are some of the warning signs you have to watch out for before it is too late.

Increased running time
If you noticed that your system takes longer to achieve the desired temperature than before, it could be because of its inefficiency. Taking a longer time to get the desired warm or cold temperature means that your HVAC system cannot produce and circulate the indoor air effectively and efficiently. But before purchasing a new HVAC system, check if your coils and blower motor are broken or damaged. Otherwise, it is time to replace the unit.

Loud noises
HVAC systems may produce noises as it gets older; however, it shouldn't be loud and disturbing. Some of the noises you need to be aware of are loud humming of the blower, noise in the outdoor unit, banging and groaning noises in the furnace unit, and strange noise before the AC's start-up. However, these noises could be because of loose parts that need to be fixed or replaced. But if the loud noises remain after the heating and air repair, then your HVAC system needs to be replaced.

Lots of repairs
As the HVAC system gets older, it requires more repairs and replacements than before. So, it is better to assess whether the accumulative repair costs are more than the price of a new HVAC system or not. The upfront payment you need to shell out for a new HVAC system might be expensive for now, but it is also essential to calculate the amount you will be paying for repairs in the long term.

The age of the HVAC system is more than ten years old.
If your HVAC system marks a decade, the repair will be more frequent since the parts start to become faulty. And if you manage to maintain your HVAC system properly, it might last a little longer. But since the technology ten years ago is different from the present, your 10-year old HVAC system is already outdated and inefficient. Today, HVAC systems are more energy-efficient, which saves more money in the long run.

HVAC systems are one of the essential equipment, both residential and commercial. It provides comfort to the people dwelling pr working in the place. That's why It is vital to know how to properly maintain it when to replace it before it is too late.
