They offered to come out and perform an investigative assessment of our issue and propose alternative solutions. Carlos came out and performed our initial assessment. They were the second team to come out and perform the inspection. He his evaluation provided the same assessment as the first vendor; however, his professionalism, polite yet candid explanation, offered alternatives, and comforting competence made us know that this team was the one for us. Primary alternatives were to (a) repair the broken blower motor or (b) replace the Furnace (heater) and Compressor (A/C). Based of the assessment, age of system, and condition other components, we opted to go with replacing the system. Their pricing was extremely competitive, personnel were very honest, perceived competence was the highest, and proposed hardware was highly rated. The installation was fast, cleanly done, and top notch. They arrived on time and provided progress assessments during the installation. They even provided before, during, and after photos. They will be our first choice for all future HVAC work!
