When your commercial HVAC system isn’t working properly, you’re most likely going to get an earful from clients, customers, tenants, and/or employees. These people expect you to provide them with enough cooling or heating power to stay comfortable while on your property, whether it’s for 8 hours at a time or for a quick shopping trip. So if you want to improve work morale and keep clients and customers returning, you need to fix your unit quickly.
Fixing a large commercial unit may be an ordeal, especially if no one has looked at your commercial unit in quite some time. Because some business owners or managers may be concerned about the cost, they often try to look into the situation themselves. You should keep in mind, however, that repairing a large commercial HVAC system is very difficult—a task that even many residential HVAC technicians prefer not to take on. While most commercial heating and air conditioning problems should be addressed by a technician, there is one thing you should check before calling a professional: the thermostat.
If your thermostat has controlled the temperature in the building proficiently ever since you’ve managed the property, you may not assume that this part could be responsible for any mechanical issues. But it’s best to double- and triple-check the thermostat before calling for backup. Nearly every technician has a story about showing up to a home or business only to find that a child has messed with the thermostat settings or that it was never turned on in the first place.
Ask yourself the following questions while examining your thermostat:
- Is the thermostat switched into the right mode? Is it set on “heating” or “cooling” as needed?
- Is there a program in place that may have shut off the heating unit for the time being?
- Is the thermostat set to today’s date and time? Many thermostats are programmed to turn on and off at certain times of day.
- Are you locked out of the thermostat? Check your manufacturer’s guide to learn how to re-access the controls.
Sometimes, the settings on the thermostat are at fault, but other times a thermostat is malfunctioning due to improper wiring or a faulty sensor. In most circumstances, you’ll have to call in a professional for repairs.
