Believe it or not, heating and air-conditioning contractors are not super heroes. We just play them on TV. Mistakes are made—and those mistakes often hurt performance and efficiency of the systems being installed and maintained. Sometimes, those mistakes hurt the customers. And, sometimes, they even hurt the business. At Air-Dynamics, we don’t run from mistakes. Instead, we seek to identify the most common errors and aggressively meet those challenges head on, so as to ensure that we are always the overachieving exception rather than the underachieving norm. The following are the seven biggest mistakes we see being made throughout the industry: 1. Misunderstood combustion safety If an HVAC contractor responds to a call about carbon monoxide, they’ll usually go straight to the furnace and look for cracks in the heat exchange. If and when they’re unable to locate said crack, they often figure everything is on the up and up. So, instead, they simply… Continue reading

When it comes to cheeseburgers, paychecks and defensive tackles, bigger is better. But, for HVAC equipment, that’s not always the case. As we’ve touched on in the past, the HVAC system has become a problem source for home efficiency, and incorrect equipment size is a problem with consequences that, perhaps, are not being adequately communicated. Here are five reasons that oversized equipment is no good: 1. Dollars & Cents Oversized equipment has a higher initial cost and costs more to operate. That’s because the system runs in short bursts, which is about as inefficient as the rush hour stop-and-go routine is on your car’s fuel mileage. Longer run times reduce cycle losses and bolster efficiency. It’s also just plain hard on your stuff. An oversized compressor is destined for a short life. 2. Comfort Oversized equipment causes temperature swings. Shorter cycles leave your system playing catch-up—particularly along the perimeter of… Continue reading
