COVID: A Message To Our Clients

This is an unprecedented time for everyone, and the situation is changing daily. As COVID continues to impact the global community, we at UMES are committed to maintaining safety in our business operations and ensuring you continue to receive the highest quality service from us without disruption. We understand that HVAC and building engineering are critical services, and we remain fully committed to fulfilling the needs of our customers and community. We require all technicians to be equipped with personal protective equipment (PPE) when needed for peace of mind and prevention.

For the safety of our employees and customers, prior to booking an appointment and again prior to our technicians arriving to a home, we may make inquiries to confirm there are no occupants of a customer’s residence experiencing any symptoms of concern and to confirm we have explicit authorization to service the residence.  We also reserve the right to postpone or cancel service in situations where symptoms such as shortness of breath, coughing, and fever are encountered or confirmed.
