Despite the most significant quarterly plunge in U.S. economic history, HVAC sales are booming — and not just any sales, but high-end, top-dollar residential HVAC systems in particular. It’s part of a national trend. After months of lockdown, some consumers are rushing to make the types of big-ticket items that would — in a typical downturn — be the first to get cut. In June, U.S. new-home sales reached a nearly 13-year high; sales of existing homes had their largest month-over-month gain ever. Home improvements have spiked, too. After all, if you’re going to be stuck at home, the reasoning goes, you might as well be comfortable while you’re there. HVAC, as the key to indoor comfort, has become a spending hotspot. No one wants to stay at home 24/7 with a broken air conditioner. Add the fact that proper ventilation and air filtration are critical in combatting the coronavirus, and the scene is set for contractors to sell, sell, sell all season.
