Air conditioning systems do more than simply cool the air: they lower humidity, and also remove dust and dirt by moving the air through filters. The simplest and often the most effective maintenance is to regularly, change or clean your air filter, which is found inside the systems heating system, air handler or affixed ductwork. When these filters come to be obstructed with dirt, the system must work harder to do its job. This squanders energy and can easily make utility costs rise. Depending on the amount of dust in the air, filters can easily become blocked in just a month or 2 of operation. The majority of domestic systems have disposable filters. These ought to be examined every 2 months once a month throughout peak use and replaced when necessary. Permanent filters ought to be cleaned in accordance with the manufacturers instructions. Under no circumstances should you operate your system without filters. To do so could possibly result in a need for more frequent cleaning of the heat exchangers.
One of the easiest perks to document is how HVAC maintenance impacts energy efficiency. Facilities where proper HVAC maintenance is completed will use a minimum of 15 to 20 percent less energy than those where systems are allowed to degrade. For example, think of the operation of a central building chiller Air Conditioning Repair Phoenix AZ . Building chillers normally are the single biggest user of electricity in a facility. To keep them operating as effectively as possible, maintenance jobs should be done on a day-to-day, weekly, monthly and yearly basis. Let them lapse, and efficiency will certainly decrease, increasing energy use. Start with the chiller operating log. Work with the chiller manufacturer or a service company to convert the log information into an operating efficiency curve for the chiller.
Develop a comparable curve for what the efficiency of the chiller would be if all maintenance were done at the suggested intervals. The distinction between the two operating efficiencies can be translated into energy and cost savings. Due to the high energy use of the equipment, even small increases in efficiency will result in sizable savings. While the energy saving estimates for chillers, boilers, and many other HVAC systems is straightforward, other estimates might not be. Think of outside air dampers. Air dampers need regular maintenance to respond appropriately to the temperature control systems demand for ventilation. If the damper linkage is out of adjustment, or if it sticks open, more ventilation will be introduced than necessary, requiring the system to use more heating or cooling energy to condition that air.
Contrary to popular belief, air conditioners do not consume refrigerant, like an automobile consumes oil. Under perfect conditions, you will never need to add or change the refrigerant in your air conditioning system. If you do find that your refrigerant levels are low, this indicates a leak in your system which ought to be fixed before you add refrigerant. While the majority of new system hookups are welded to minimize cracks, numerous older units 8 years or older were connected with mechanical flared fittings which can easily shake loose over the years, creating cracks.
