Jaren is knowledgeable, engaging, professional. Haller could not be better represented. I had a second visit for my AC. It turned out to faulty wiring job by the initial installers. Jaren and Pete were very professional about what turned out to be a dirty job.

During a yearly pre heat system maintenance visit a problem was noticed with the Emergency heat unit. It was ordered and replaced and is now working after a period of troubleshooting. Turned out one of the coils was touching the side of the housing causing one of the breakers to trip. Mistah Williams stuck with it and discovered and fixed the issue. Nicely done!

The technician listened to my questions, and provided answers that were very helpful. He serviced the tankless water heater, and instructed me as to how to drain the 55 gal holding tank. Very satisfied!
