Are you a small business owner? Have you recently moved into a retail space? When you are renting a commercial location, there are things that are sometimes handled by the building owner and that are sometimes handled by the company leasing the space; in this case, that'd be your company. One such thing may be the maintenance and upkeep of the HVAC system. It may be the building owner's responsibility to replace the unit if it breaks, but your lease may also say that it's your responsibility to keep it running. Fortunately, you don't have to know anything about HVAC systems nor do you have to hire an employee who does. All you need to do is hire a company to take care of everything for you. But before you attempt to simply hire the first HVAC company you find, here are some questions that you need to ask:
Are you licensed and insured? For a variety of reasons, it's important to make sure that the company that provides your HVAC services is licensed and insured. Because you don't own the property, your lease likely says that you are liable for any damage that occurs to the building and its various components. If you hire an unlicensed and uninsured company to maintain the HVAC system and they cause damage, the building owner will likely go after you for the cost of repairs because it was your responsibility to vet everyone you hired. It may cost a bit more to hire an HVAC company that can show proof of licensing and insurance, but it will save you money in the long run.
Do you handle commercial HVAC issues? Not every company that offers HVAC services will work on commercial properties. Some work only on commercial properties, some work on residential properties, and a few companies will work on both types of systems. While they are almost identical, there are enough differences in HVAC residential and commercial systems that a technician who is trained in one may not necessarily do their best work if they work on the other type.
What services do you provide? Even if you do find a company who offers commercial HVAC services, this doesn't necessarily mean that they are able to provide regular maintenance. Some companies only repair and replace units that have broken down while others will have technicians available to do routine maintenance like replacing filters or switching the system over from cooling to heating, as applicable. Depending on where you are located, it may be more or less difficult to find one company who is able to do everything that you need to have done.
