Based on 19 years of covering automotive retailing, I would say the future of residential HVAC looks a lot like the current state of automotive retailing.
2018 was a great year as far as the U.S. economy was concerned. Sales of HVAC equipment remained strong, the unemployment rate stayed below 4 percent, and the GDP increased.
Average sales for HARDI members increased by 3.6 percent in December 2018, and the average annualized growth for the 12 months through December was 11.4 percent.
