Trust DML Electric for any electrical wiring repairs or upgrades related to your HVAC or air conditioning system
Licensed HVAC Wiring for Bend and Central Oregon Homes
Trust DML Electric in Bend, Oregon, for repairs, replacement, and upgrades to your HVAC wiring. We can also help you install ductless mini-split systems. Whether you’re installing a new HVAC system, replacing an aging unit, or adding central air for the first time, our licensed electricians make sure your wiring is ready to handle Central Oregon’s hot summers and cold winters.
HVAC wiring includes the cables, connections, fuses, and control components that power and manage your HVAC equipment. This system relies on two main circuit types. A low-voltage control circuit lets your thermostat send signals. A high-voltage power circuit, meanwhile, delivers electricity to components like the furnace, air handler, and outdoor condenser unit.
Safety & Code Compliance:
DML Electric will ensure that all HVAC wiring is correctly sized, safely installed, and meet local electrical codes and the National Electrical Code (NEC) to ensure proper performance and prevent hazards.
Installing or repairing HVAC wiring requires specialized knowledge of both electrical systems and HVAC operations, making it a job for trained professionals like DML Electric.
When Your HVAC System Needs an Electrical Upgrade
Older homes and businesses throughout Central Oregon often have electrical panels that weren’t built to handle modern HVAC systems, especially larger heat pumps or multiple ductless mini-split units. If you’re upgrading your HVAC system or adding central air for the first time, your panel may need additional capacity to safely support the added load. DML Electric can evaluate your panel and complete any necessary electrical service and panel upgrades at the same time as your HVAC wiring, so you only need one appointment for both. We also provide commercial electrical services for businesses managing HVAC systems across Central Oregon.
