When your commercial HVAC system isn’t functioning properly it’s pretty easy to identify. When the temperatures aren’t what they are supposed to be, you’ll likely hear from your customers, employees, tenants, and so forth.

There’s an expectation with customers and tenants that the temperatures will be set appropriately while on your property, whether they are living there or just dropping in to purchase something. To keep everybody happy, you need to fix this quickly!

Repairing a large commercial HVAC unit can be quite an undertaking, particularly if it hasn’t been maintained properly over time. Some business owners, in order to keep costs down, opt towards looking at, and attempting to repair, the units themselves. This is not advisable, as a large HVAC system is really very complex, and needs to be tended to by professionals. That also means avoiding hiring residential HVAC companies to handle commercial HVAC systems. They simply aren’t capable or trained to deal with it.

There is one thing that business owners can check prior to calling a commercial HVAC company. That is the thermostat.

Because the thermostat has worked properly up until now, business owners with a commercial HVAC problem may not consider checking it, assuming that it is still functioning properly. That is why it is wise to check the thermostat once, or even twice, before calling in the professionals. It is a common story among commercial HVAC professionals to be called in on a job only to learn that somebody’s been tinkering with the thermostat! Three things that you can check regarding the thermostat for calling in a commercial HVAC specialist are:

  • The thermostat is set to the correct mode. Is the unit set to heat when it should be set to cooling? Is the reverse true?
  • The thermostat is set to the correct date and time. Oftentimes thermostats are placed on schedules, and if the date and time is incorrect that will throw off the timing of the schedule.
  •  There isn’t a program in place that is shutting the unit down. Has the unit been programmed to shut down without your knowing it?

It is critical to check these three things before calling in a commercial HVAC specialist. You can save yourself a lot of time and a lot of money. If you happen to find that you are locked out of the thermostat, as happens from time to time, check the owner’s manual to find out how to access the thermostat.

If you are able to determine that one of these factors is at the source of the problem, fantastic! Sometimes the thermostat itself is not functioning properly, and if this is the case you’ll want to call in a professional to have a look at it and possibly replace it.

You are now equipped to determine if the thermostat is causing the problems for your HVAC system. If you find that all of these check out, and there doesn’t appear to be a problem here, contact us.
