Covid-19 Update

We are open for business. If you need residential or commercial sales, service or installation we can help. With the best interests of you and our employees in mind we are following all recommended CDC guidelines. Our technicians will wear a mask when they are in your home. They will wipe down everything they touch including the thermostat and any door knobs. They will stay home if they are experiencing any covid systems. They will also keep their distance.

Thank you for trusting Seliga Heating and Cooling to keep you and our employees safe.

If you need us, we’ll be here, 314-481-7333.
