As both our internal and external environment changes, the HVAC industry also changes and develops new technologies in heating and cooling to meet new improved energy efficiency standards. For example, 30 years ago, HVAC systems consisted of single-stage motors and mercury thermostats that maintained a steady temperature 24 hours a day unless the dial was turned up or down. Today, we have programmable thermostats that allow multiple temperatures to be set, depending on the time and day of the week, and we have variable-speed motors that can decrease or increase, depending on cooling or heating needs. The 2019 HVAC trends are forecast to involve better HVAC connectivity and data as well as improvements in green HVAC technology.
You finally get home after a long, chilly day. As soon as you come inside, you crank up the thermostat hoping to knock some of the chill out of your bones. But instead of being greeted with a warm, gentle breeze from the furnace, you’re startled by the sound of an earsplitting, hair-raising screech.
Your first thought is probably, “That sounds expensive.”
A screeching heater is unnerving. However, most of the time, it’s a simple fix that requires a bit of expert knowledge and skilled hands to repair. It’s not a sound that you want to turn up the TV and ignore, though—the longer your heater screeches, the more you risk costly damage.
Let’s take a look at the most common causes of a screeching or squealing heater.
Have you heard of the new extreme green hyper heating systems? It is entirely okay to answer 'no' - hyper heating has been around only for slightly more than a decade, so it is still a relatively new term in the HVAC field. The technology was initially developed by Mitsubishi in order to manufacture an extremely energy efficient, durable and reliable heat pump with the ability to operate in temperatures below freezing. These units use inverter technology in order to improve heating and cooling efficiency along with Mitsubishi’s H2I™ technology.
Is your Chicago building still relying on traditional building optimization? If it is, you could be spending more on your energy usage than you really need to spend. This is because modern building optimization provides real-time data and metrics so that you can make adjustments immediately rather than relying on separate inspections of your critical equipment so that you can implement energy-saving ideas.
Your furnace clicks on and the blower motor is running, but the air coming from the vents is cold or cool instead of hot. Or maybe the air starts off hot, then turns cool before the furnace shuts down.
Let’s look at some of the solutions to this common furnace problem.
When is the last time you evaluated the capacity of your HVAC system? If your facility has recently added new critical equipment or expanded your electronics, the added heat created by the equipment could be overtaxing your HVAC unit, resulting in higher energy bills and more frequent repairs.
Gas fired appliances like furnaces, boilers and water heaters create gases as a byproduct of the combustion process. In order for these appliances to work safely, they must be vented properly and maintain a proper draft to make sure the gases exit your home. Gas leaks, high carbon monoxide levels, and improper drafting can all be dangerous if not addressed.
If your multi-unit residential building in Chicago has a chiller, you might be surprised to know that operating it at full-capacity may not be the most efficient way to run your cooling system, and it could be costing your building money in the form of higher energy bills. In fact, AchrNews states that chillers can account for as much as 50 percent of the utility usage in your residential multi-unit building. Thankfully, there are things you can do to maximize your chiller’s energy efficiency.
With this summer’s extreme heat, it is extremely important to perform preventative maintenance on your HVAC equipment. Extremely high temperatures cause HVAC units to work longer, thusly increasing the wear and tear on the internal components and causing higher energy bills.
