How Long Do HVAC Systems Last?
If you are looking for an HVAC system for sale or hoping to buy a property with an AC unit, it is vital to understand how long the HVAC system will last. It is also essential to understand maintenance requirements for different HVAC system brands. The age of the system is not the only thing to consider when determining how long it will last.
The average lifespan of most HVAC system types is between 15 and 20 years. However, regular maintenance of your HVAC system can determine its longevity. In addition, some HVAC components should be replaced, including the air filter should be replaced regularly.
If one of the members of your household has allergies, consider replacing the air filter every month. Otherwise, you can replace the filter after three to six months. Although some homeowners do HVAC maintenance on their own, it is essential to leave this task to professionals.
HVAC contractors can clean and examine your HVAC system for signs of damage. A good contractor will tell you your classification of HVAC system and if it requires repair or maintenance before it is damaged completely.
One of the best times to undertake routine HVAC maintenance is during early spring. The maintenance will ensure your system continues working during summer when you need it the most. On the same breath, it is crucial to undertake HVAC maintenance for your furnace before winter sets in.
Upgrading Your System
Consider replacing older HVAC systems by upgrading to a new system. HVAC system prices vary depending on the model. The upgrade should be a serious consideration, especially if components start to break down. Replacing a damaged condenser or evaporator coil can be as expensive as replacing the entire unit.
Some homes have old HVAC systems that were installed more than 20 years ago and should have been replaced much earlier. Finding a sound HVAC system for sale and replacing old HVAC systems will save you from unexpected breakdowns and lower your heating costs.
Factors that Determine How Long HVAC System Brands Will Last
Many factors determine how long your HVAC system will last. Today’s systems are dealing with weather conditions different from the ones experienced two or three decades ago. The earth is getting warmer, and many household items produce particulates that affect the lifespan of HVAC systems.
Some building components are made of chemicals that can damage HVAC system components such as condenser coils much faster. In addition, modern methods of building residential and commercial structures eliminate draft. This is certainly an advantage because it translates to lower energy bills. However, the fact that draft is eliminated means chemicals from cleaning products and particulates remain in the air in your home for prolonged periods. This explains why outdoor HVAC systems usually last longer than indoor systems.
A significant factor that determines how long your HVAC system will last is how you use it. In some parts of the U.S., homeowners use their HVAC systems for only a few months in a year. The less often you use your HVAC system, the longer it is likely to last. HVAC systems experience wear and tear with prolonged use.
The two main factors that determine how long your HVAC system will last are oversizing and poor maintenance. Poor maintenance or lack of maintenance can expedite the wear and tear of HVAC components and shorten its lifespan. In addition, oversizing can lead to many problems, including the failure of the compressor or blower motor.
Your HVAC system is likely to last for a shorter period in coastal areas because salty air corrodes the condenser unit.
HVAC Equipment Lifespan
A properly maintained gas furnace can last for two or three decades. One of the things that may lead to the replacement of the furnace is the leakage of the heat exchanger. The heat exchanger is one of the most essential and costly components of a gas furnace.
These HVAC components usually have a longer lifespan than furnaces and may last for an average of 20 to 35 years. Like the furnace, the leakage of the heat exchanger may require replacement of the entire boiler.
Most air conditioning systems will last an average of 15 to 20 years. However, the lifespan of air conditioning units in coastal areas is typically shorter lasting between 7 and 12 years. Air conditioners require replacement when the compressor or condenser fails.
This HVAC component can last between 10 and 20 years. Usage frequency determines how long a heat pump will last. Heat pumps have a similar working principle as AC units. However, heat pumps can provide both heating and cooling. Therefore, they are usually used throughout the year hence their shorter lifespan.
Your home’s HVAC system will typically last longer with proper maintenance and servicing. However, the average lifespan of HVAC systems is 15 years.
