Comfort, Reliability, Asset Protection

As a service customer, you benefit from MacDonald-Miller's commitment to keep your building running smoothly and efficiently. More than peace of mind, it means that your building systems are being inspected and maintained regularly. Mechanical equipment is tested, aligned, calibrated, lubricated and its performance recorded - extending the life of your equipment and reducing downtime or emergencies.

The Big Guys

MacMiller is the largest service organization north of San Francisco. We have the technical knowledge, experience and people power to resolve any service challenge.

4-Hour Priority Response & 24/7 Service

During the workday, our zone-based teams are nearby to quickly respond to your service needs. On weekends and overnight, we dispatch on-call service technicians to take care of your facility.

Fix-It-Once Extended Repair Warranty

Occasionally breakdowns occur. If you do need a repair, all parts and labor are warranted for one year. Any unit replacements are covered with an extra year of warranty - for a total of two years.
