HOW OFTEN DOES HVAC SYSTEMS NEED MAINTENANCE?
An HVAC system needs regular care and maintenance to ensure it works consistently and does not require replacement all the time. Not only does HVAC maintenance have an impact on occupants’ health but it also helps detect early problems, which will help save costs on larger problems and ensure your building is running at its full potential.
Our team at WATT HVAC often receives that question from our clients. Please consult this guideline to ensure your system is working well at all time.
1. SERVICE TIMELINE
Most HVAC professionals in the commercial division say you should get your equipment inspected quarterly (every 3 months). We at WATT HVAC highly agree with this recommendation. Commercial equipment works harder and more often than equipment in your house and is subject to more wear and tear. Keeping your system clean and addressing problems before they become bigger problems will save you not only long equipment down times, but also costly unneeded repairs. Depending on the type of systems in your commercial building, there are seasonal considerations that should be performed at appropriate times. Whether you have a cooling tower that needs to be winterized or a chiller that needs its tubes punched, there are optimal and non-optimal times to complete these jobs. You do not want to have to shut down your entire building cooling in the middle of summer to be doing repairs or maintenance that could be done in the fall or winter. The same goes in the winter, you don’t want to be shutting down your heating system in the winter if it is something that could be done in the cooling season. Thinking ahead and planning for these circumstances ahead of time can prevent a lot of headaches and complaints.
