The Significance Of HVAC Upkeep

Contrary to popular belief, air conditioners do not consume refrigerant, like an automobile consumes oil. Under ideal conditions, you will never need to add or change the refrigerant in your air conditioning system. If you do discover that your refrigerant levels are low, this suggests a crack in your system which ought to be fixed before you add refrigerant. While a lot of brand-new system connections are welded to reduce cracks, many older units, (8 years or older), were connected with mechanical flared fittings which can shake loose over the years, creating cracks.

One of the easiest benefits to document is just how HVAC maintenance impacts energy effectiveness. Facilities where correct HVAC upkeep is completed will make use of at least 15 to 20 percent less energy than those where systems are allowed to deteriorate. For example, think about the operation of a central building chiller. Building chillers normally are the single largest user of electrical power in a facility. To keep them operating as effectively as possible, upkeep tasks have to be done on an annual basis. Let them lapse, and efficiency will decrease, increasing energy usage. Begin with the chiller operating log. Work with the chiller maker or a service company to convert the log data into an operating efficiency curve for the chiller.

Establish a comparable curve for what the efficiency of the chiller might be if all routine maintenance was done at the advised intervals. The difference between the two operating efficiencies can be translated into energy and expense savings. Due to the high energy usage of the equipment, even little increases in efficiency will result in large cost savings. While the energy saving estimates for chillers, boilers, and numerous other HVAC systems are straightforward, other cost saving estimates might not be. Think of outside air dampers. Air dampers need routine maintenance to react correctly to the temperature control system's demand for air flow. If the damper linkage is out of adjustment, or if it sticks open, more air flow will be introduced than needed, requiring the system to make use of even more heating or cooling energy to condition that air.

Air conditioning systems do more than just cool the air; they lower humidity, and also get rid of dust and dirt by moving the air through filters. The best and often the most effective upkeep is to frequently change or clean your air filter, which is located inside the system's heater, air handler or attached ductwork. When these filters become obstructed with dirt, the system must work harder to do its job. This wastes energy and can make utility bills rise. Depending on the amount of dirt in the air, filters can become blocked in just a month or 2 of operation. Many residential systems have reusable filters. These ought to be checked every 2 months} throughout peak usage and changed when needed. Permanent filters ought to be cleaned in accordance with the maker's directions. Under no circumstances should you operate your system without filters. To do so could possibly cause a requirement for even more frequent cleaning of the heat exchangers.

Think of your HVAC unit like an automobile. It has a motor and runs off a certain sort of energy. In the same way that you change your car's oil, spark plugs, charge the battery, etc, these HVAC motors also require routine attention to run efficiently and successfully.Visit\n
