Before You Call

A few details help us schedule the right technician and get your problem solved faster:

• The type of system: furnace, boiler, heat pump, mini-split, central air, geothermal or water heater
• What it’s doing, such as no heat, no cooling, a leak, a noise or an error code
• The make and model from the equipment label, if it’s easy to reach
• Your town and the best way to reach you

If you smell gas or a carbon monoxide alarm goes off, leave the house and call 911 or your gas utility first. Then call us once everyone is safe.
