Air conditioning systems do more than just cool the air: they reduce humidity, and also get rid of dust and dirt by moving the air through filters. The best and often the most effective routine maintenance is to routinely, change or clean your air filter, which is located inside the systems heating system, air handler or affixed ductwork. When these filters come to be clogged with dirt, the system must work harder to do its job. This wastes energy and can make utility costs rise. Depending on the amount of dirt in the air, filters can become clogged in just a month or two of operation. Most residential systems have non reusable filters. These should be examined every two months once a month during peak use and replaced when needed. Permanent filters should be cleaned in accordance with the makers instructions. Under no circumstances should you operate your system without filters. To do so could possibly lead to a need for even more regular cleaning of the heat exchangers.
One of the easiest benefits to document is how HVAC upkeep impacts energy efficiency. Facilities in which appropriate HVAC routine maintenance is completed will make use of a minimum of 15 to 20 percent less energy than those where systems are allowed to degrade. For instance, think of the operation of a central building chiller. Building chillers normally are the single biggest user of electricity in a facility. To keep them operating as effectively as possible, routine maintenance jobs have to be done on an everyday, weekly, monthly and yearly basis. Let them lapse, and efficiency will certainly reduce, increasing energy use. Start with the chiller operating log. Work with the chiller maker or a service business to convert the log data into an operating efficiency curve for the chiller.
Develop a comparable curve for what the efficiency of the chiller would be if all upkeep were done at the recommended intervals. The difference between the two operating efficiencies can be translated into energy and cost savings. Due to the high energy use of the equipment, even little increases in efficiency will result in huge cost savings. While the energy saving estimates for chillers, boilers, and lots of other HVAC systems is straightforward, other estimates might not be. Consider outside air dampers. Air dampers require regular upkeep to respond appropriately to the temperature control systems demand for ventilation. If the damper linkage is out of alignment, or if it sticks open, more ventilation will be introduced than needed, requiring the system to make use of even more heating or cooling energy to condition that air.
Contrary to popular belief, air conditioners do not consume refrigerant, like a vehicle consumes oil. Under ideal 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 should be fixed before you add refrigerant. While a lot of brand-new system hookups are welded to minimize leaks, numerous older units 8 years or older were connected with mechanical flared fittings which can shake loose over the years, creating leaks AC Services McKinney TX .
