How To Maintain Commercial HVAC Systems
A commercial HVAC system for your business is a sizable investment, so you want it to last as long as possible. When you maintain it properly, a commercial HVAC system will last 15-20, but what does that entail?

Commercial HVAC Maintenance vs. Commercial Repairs
What’s the difference between maintenance and repair? Simply put, maintenance is a step you can take to prevent the need for repairs. While you can schedule maintenance in advance, repairs tend to need an immediate response, which can cost more. Problems that require repairs can result in HVAC system failure if you don’t address them quickly.
Benefits of Commercial HVAC Maintenance
You may think you can skip regular maintenance if your system is working correctly, but several benefits accompany standard HVAC service:
- Fewer repairs
- Extends the lifespan of the unit
- Reduces utility costs
- Improves indoor air quality
Frequency of Maintenance for Commercial HVAC Systems
We recommend scheduling maintenance for your HVAC system twice yearly, in the spring and fall. A thorough check of your system at those times will ensure it runs efficiently when needed most during the summer and winter seasons. The end of summer is a great time to clean up any vegetation blocking access to the outdoor unit and check for damage from summer storms. Our technician can also check to ensure no small animals or other pests have taken residence in the system.

Steps You Can Take to Maintain Your Commercial HVAC System
Regular maintenance is an excellent way to keep your commercial HVAC system in good shape, but it isn’t fail-proof. There are a few things you can keep a watch for to know if you need to schedule a service appointment:
- Increase in energy bills: If your energy costs are rising but you haven’t changed your usage, your system will likely not run efficiently.
- Reduced airflow: A significant decrease in airflow can be a sign of a clogged duct or air filter.
- Loud or unusual noises:
Every machine makes noises, but if your HVAC suddenly becomes louder or makes sounds you’ve never heard, call us.
