@yeseniasep67448 that will totally depend on where you are located and if this is still use for any kind of patient care. If so, you know it will get expensive because of BioMed regulations etc. In theory, you can only use those that are "certified" to work on this type of equipment. If this is not used for patient care etc. You could get this fixed by any decent HVAC technician or general electrician. You could probably even do it yourself. After all, iFixit is trying to empower YOU to fix your own devices :-)
