Customer Story in Longmont, CO


I Am Having Issues with My HVAC System


Dayna, a Longmont resident, was not getting any heat from her heating system.


One of our team members, Cody, jumped at the chance to solve Dayna’s problem. He isolated power to the unit, removed and marked all wires, and removed the old contactor. He matched a new contactor with the data plate. He then reattached wiring and ensured the connections were tight. He tested for proper operation, which was successful.

Customer Testimonial

"From the first phone call, I knew I had made the right decision."

From the first phone call, I knew I had made the right decision. She took my information and let me know she would be calling me back as soon as she checked with the schedule. Not only did I receive a call back, but I received a text message with a full bio and photo of my technician. Cody was very thorough and extremely knowledgeable. I would highly recommend Plumbline.
