There are a number of factors that can impact how long a commercial HVAC unit lasts. These factors include:

• Size of the unit
• Frequency of maintenance
• Frequency of filter changes
• Proper installation of the HVAC unit
• Correct sizing of the unit for the building
• State of the ductwork in the building

If a new commercial HVAC unit is properly sized, installed, and maintained, then it can last up to 15 years before needing to be replaced.

High-efficiency commercial AC and HVAC systems are always worth the extra investment. Heating and cooling large commercial spaces can be incredibly expensive. A high-efficiency system can substantially reduce your monthly heating and air conditioning costs to the point where the increased initial costs of the unit can be recovered by around the half-way point of the unit’s lifespan.

Air filters should be checked monthly and changed if they are dirty. Doing this will help get the most out of your commercial AC system by keeping it running efficiently, and keeping the air quality in the building at a good level.

We recommend having any commercial AC or HVAC unit serviced and maintained once per year. Doing this will keep the unit running optimally for years to come and ensure that the unit lasts as long as possible before needing to be replaced.

Ductwork maintenance is a very important part of HVAC system maintenance. Making sure these ducts are clean and properly sealed ensures maximum efficiency of the unit. An air leak in ductwork will contribute to substantially higher energy bills and shorten the life of the HVAC unit because it will have to work harder to properly cool your commercial space.
