Highland Heating & Air Coronavirus COVID-19 Readiness:

At Highland Heating and Air, our top priority is promoting the wellbeing of our customers, team members, and the broader community.

We are monitoring news about COVID-19 (the illness caused by the coronavirus). We understand the concern that the spread of the virus has caused.
We want to assure you that we are committed to being responsive to the needs of our customers as the situation evolves.

While we continue to offer regular service and after hours services for emergency situations as normal, we are asking all customers to refrain from coming to our office and to contact us via our main phone 303-848-0095 or here on our website highlandheating.com.

While we are following the recommendations of the CDC and asking all of our staff to perform self evaluations of their health each day before arriving to work, we will also appreciate anyone that has a scheduled appointment with us to also evaluate their personal and family health and reschedule as needed.

For additional information about COVID-19, visit the Centers for Disease Control and Prevention at cdc.gov
