🛡️ 360 HVAC Pro | Furnace tune-ups with a carbon monoxide check.
Carbon monoxide has no color and no smell, and a furnace that burns gas poorly can produce it. The CDC lists headache, dizziness, weakness, upset stomach, and confusion as common symptoms. It also recommends having your heating system serviced every year.
Our furnace tune-up covers the checks you can't do yourself. We clean the burners, inspect the heat exchanger, test for carbon monoxide, and check the flame. A healthy flame burns blue. A yellow or flickering flame needs a technician the same day. A fall tune-up also helps your furnace run efficiently through the long Colorado heating season.
Between visits, put a CO alarm near every sleeping area and replace the batteries every spring and fall. If your CO alarm ever goes off, get everyone outside and call 911 first. Once your family is safe, a licensed technician can find the source before you run the furnace again.
Want both seasons covered? The 360 HVAC Maintenance Plan includes your fall furnace tune-up and spring AC tune-up for a flat $189 a year. Serving Commerce City, Denver, and surrounding areas.
