Absolute (Larry and Rusty) patiently asked questions about what I needed and wanted on their first visit. They did no selling. They listened. That was refreshing. We have a fine but old mid-century house. The system was mid-century. The second floor was either too hot or too cold. They designed a reasonably priced fix. They replaced the air conditioning unit and replaced a small basement heater. They installed a thermostat on the second floor. (A gift from the gods.) I took bids from four vendors. None asked me about my needs/wants...except Larry. All were considerably more expensive. I must admit, they were not the fastest guys in town. But they were continually considerate, polite, clean, and most importantly, SMART.
