Frequently Asked Questions

Maintenance should be performed at a minimum of once per year. Facilities with heavy, severe-use, or year-round process conditions should schedule service more frequently.

Regularly inspect your boiler room for unusual leaks, odors, or sounds. We also recommend asking a qualified Blizzard Mechanical technician to walk you through standard pressure gauge and thermometer readings so you know what normal operation looks like.

Contact a qualified technician immediately. As a safety best practice, ensure you and your staff know the exact locations of the electrical, water, and fuel shut-off valves.

Don’t let a boiler failure disrupt your operations. Contact Blizzard Mechanical today at (203) 735-BLIZ or submit a form online to schedule service.
