The use of CFC as a refrigerant was once common, including the refrigerants R-11 and R-12 (sold under the brand name Freon-12). Freon refrigerants were commonly used during the 20th century in air conditioners due to their superior stability and safety properties. When they are released accidentally or deliberately, these chlorine-bearing refrigerants eventually reach the upper atmosphere. Once the refrigerant reaches the stratosphere, UV radiation from the Sun homolytically cleaves the chlorine-carbon bond, yielding a chlorine radical. These chlorine radicals catalyze the breakdown of ozone into diatomic oxygen, depleting the ozone layer that shields the Earth's surface from strong UV radiation. Each chlorine radical remains active as a catalyst until it binds with another radical, forming a stable molecule and quenching the chain reaction.
Clean air delivery rate is the amount of clean air an air cleaner provides to a room or space. When determining CADR, the amount of airflow in a space is taken into account. For example, an air cleaner with a flow rate of 100 cfm (cubic feet per minute) and an efficiency of 50% has a CADR of 50 cfm. Along with CADR, filtration performance is very important when it comes to the air in our indoor environment. Filter performance depends on the size of the particle or fiber, the filter packing density and depth and also the air flow rate.
Heaters are appliances whose purpose is to generate heat (i.e. warmth) for the building. This can be done via central heating. Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air in a central location such as a furnace room in a home, or a mechanical room in a large building. The heat can be transferred by convection, conduction, or radiation.
Although your AC may continue to work for a time, if you ignore warning signs of air conditioner repair troubles, it can be much more costly to repair in the long term. Diminished cooling capacity not only makes your home uncomfortably warm, but it also raises your utility bills significantly as your unit struggles to maintain the desired temperature ineffectively. A system put under strain is likely to overheat, resulting in major damage. Therefore, it is best to have your air conditioner repaired promptly when you discover signs of trouble.
2) Keep your coils clean. The AC coils and fins on the outside of your unit need to be kept clean and clear of obstructions. Leaves and other debris sometimes accumulate around your unit. If obstructions are present, your unit must work harder to function than it should. You can clean your unit with a regular garden hose and a broom. Do not use a pressure washer, as the strong spray could cause harm to your system. A little bit of housekeeping in this regard goes far toward keeping your air conditioner working optimally.
In the fall you should prepare your HVAC unit for winter. Turn off your air conditioner’s circuit, then hose it off to remove debris. It must dry completely. Do this when it’s warm enough that there’s no risk of the water freezing. Cover the exposed pipes with foam pipe insulation ($1-$3), and protect your entire unit with a weatherproof cover ($20-$50).
Fast forward 1 year and 1 week and the circuit board that HVAC Service had installed has failed again. They came out and said that it failed from water condensation dripping onto it, so we needed to replace it and reroute the pipes to prevent future water damage. That would cost double what I paid last year. Why didn't they fix the problem last year at the initial repair instead of putting in a circuit board that was bound to fail again?!? They were strongly recommending that the furnace be completely replace for a huge fee to avoid the same thing happening again. I paid $59 for them to tell me they didn't fix it right last year. This didn't feel right, so I sought a second opinion. I'm very glad that I found another guy to come replace the circuit board and put it away from the water, fix the water leak, and also find and fix another impending failure. All of that was for much less than HVAC Service wanted to charge for repair or replacement. The other guy did a great repair, so I'm confident it will not break down again, but if it does, I will not call HVAC Service. Don't get suckered by their Yelp Deal.
A career in this field may require you to meet certain licensing, training, and other requirements that can vary by vocation and state. You should check with your state, local government, and/or licensing board to find out which requirements may be applicable in your state.

5) Adjust your thermostat. If you are away for large stretches of time every day, adjust your thermostat to a higher temperature for the time you are away. This will lessen the amount of time your unit has to work each day, and will lengthen its life cycle. An additional benefit will be a lower utility bill each month. Some newer thermostats allow you to pre-program your thermostat to match your schedule so that your home will still be cool when you arrive. Optimizing your system’s usage will maximize its life in the long term.

The liquid refrigerant is returned to another heat exchanger where it is allowed to evaporate, hence the heat exchanger is often called an evaporating coil or evaporator. As the liquid refrigerant evaporates it absorbs energy (heat) from the inside air, returns to the compressor, and repeats the cycle. In the process, heat is absorbed from indoors and transferred outdoors, resulting in cooling of the building.
If you can’t make up your mind about whether you should repair or replace your current unit and it’s over the age of 10, buying a new unit might very well be a better investment. AC units will no doubt need repairs every once in a while. However, if your system continuously requires repairs, these can eventually cost more than installing a new unit, making investing in a new unit the wiser choice.
