As others here have stated, Stalwart Mechanical Services is top class in every way. Both Ato and Walter are professional, punctual, friendly, very knowledgeable, willing to educate you on what the problem was, why it broke, and how they will fix it, and their services are fairly priced. Their scheduler/office manager is also kind and friendly and works with you in finding a speedy time to have someone come to you and address the issue. I have used Stalwart for both my business and my home and would not use anyone else. Big thanks to both Ato and Walter for the help and the education. These guys have integrity - an extremely valuable trait in today's society. Don't hesitate to use their services.

Stalwart Mechanical Services is ABSOLUTELY AMAZING! Furnace stopped working over night and woke to 66 degrees in my home. Called them at 5 am and got a live person who was so nice at that time of morning. She schedule a service call for the afternoon. Otto came out and quickly found the issue. Within 5 minutes I had heat again! Huge thanks to this company and Otto. They have a customer for life!

I contacted Stalwart Mechanical Services because my AC was not cooling. I received a call back within 30 minutes. The technician Mike went above and beyond the call of duty to add me to the schedule on a Saturday, he kept me updated on the progress of the work. I received exceptional customer service from Mike and he explained in detail what caused my AC to stop cooling. I would definitely refer Mike and his company to family and friends!
