When I was going over our supplier reports for our Heating, Ventilation, plus A/C company around the beginning of the pandemic, I was gratified to see that so many people were taking advantage of our discount with UV whole-house air purifiers. They very started going out of stock when the two of us decided to offer free whole-house air purifiers with every new Heating, Ventilation, plus A/C upgrade. That drove up Heating, Ventilation, plus A/C installs about 25% up from the previous year plus for us that’s huge! When the two of us were able to get our whole-house air purifiers back in stock, the two of us still kept the same discounts for as long as the two of us have been in this pandemic, however of course the sales have gone down a little bit with whole-house air purifiers, but I suppose that’s because most everybody is using advanced air purification in some way or another. You can even get Heating, Ventilation, plus A/C systems with built-in air purification these afternoons plus those systems are one of our specialties! That is one thing I am legitimately grateful for, all the advances in Heating, Ventilation, plus A/C technology over the last decade. Occasionally clients will even ask me about DIY Heating, Ventilation, plus A/C systems. I generally don’t command that just anybody install those systems. You legitimately have to have some comprehension of familiar Heating, Ventilation, plus A/C upgrade technique plus electrical connections which can be life threatening if you don’t guess what you’re doing… Generally, I can tell if a customer is capable of an upgrade savor that based on their Heating, Ventilation, plus A/C comprehension plus experience with machinery upgrades. But another thing I have to warn about is the fact that you void your warranty for the unit if not installed by a professional.
