A Great Relief for Me
I called from California to get help for my 86-year-old sister in Falls Church, VA, whose furnace failed during a terrible snowstorm with very cold temps. Donmar sent someone out immediately who fixed it quickly and dealt with my difficult sister in a very understanding way. A great relief for me.

POV P was exceptionally thorough and pointed out that we were using the wrong sized filter for our furnace and wondered why other Donmar technicians hadn’t noticed that anomaly in previous inspections.

I'm still a happy customer
Update for 2025 ...
After years of service and multiple service contracts across multiple properties, I'm happy to say I'm still a happy customer. Their staff is always friendly and patient to explain whatever I need. They are always careful when working around the property, even when having to go from inside to outside often.
Donmar replaced a failed inducer motor in our gas furnace. We had this diagnosed by two other companies, who were more interested in replacement of the entire system.
Donmar came out the same day I called them, with the part. System was back online in an hour.
Donmar came recommended by a coworker. After this experience, I will be following up for a maintenance contract.
