Shading your unit helps protect it from heat, light, and moisture and can even help reduce your energy bill by allowing the unit to run less frequently. Plus, the dust and debris that can get into an unprotected outdoor AC unit can cause frequent breakdowns and increased wear and tear.
In short, the study concludes that the potential savings that could be achieved by shading a compressor are marginal at best. Planting trees and shrubs close by a condenser may actually reduce system efficiency due to impedance of effective air movement.
The $5,000 rule is a rule of thumb in the HVAC industry to help homeowners decide whether HVAC repair or HVAC replacement makes more sense in the long run. The $5,000 rule: Multiply the age of your equipment by the estimated repair cost. If the number is more than $5,000, then you should consider replacing your unit.
No. The gas is cooled by the flow of outside air across the coils. Whether or not it's in the sun makes no difference.
Impact Of Sunlight On Your AC
Due to that strain, your system has to work twice as hard to maintain indoor cooling efficiency, affecting your home's temperature. Sun exposure also raises the surface temperature of your condenser unit (the outdoor portion of AC), which makes the inside of the unit hotter.
Provide shade for your AC system's outdoor unit. If your air conditioner's outdoor unit (AKA. the condenser) is located in a shady spot, it won't have to work as hard to cool air as it would in direct sunlight. In a pinch, you can put up an outdoor umbrella to cast some shade on the unit.
Use economy mode
Running your aircon in economy mode will make your compressor run slower, which means the unit will consume less energy. This feature comes in handy if you are using your aircon for long periods of time. So if you use the system all day and night, simply activate the economy mode.
To cool down your home quickly with your air conditioning unit, close all windows and doors to prevent cool air from escaping. Set your thermostat to a lower temperature than the current temperature in your home. Use a fan to circulate the cool air throughout the room.
While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
Best AC Temperature Settings While You Are Home
As you consider the most comfortable room temperature for your lifestyle and family, keep in mind that for each degree that you set your thermostat above 72 degrees, you can save up to 3% on your energy bill.
Running the AC unit full-time in our big house example would cost $7.39 per day for the efficient unit, or about $222 per month. For the less efficient unit, you're looking at $10.56 per day or about $317 per month. Not only that, but running all day is hard on your air conditioner.
In short, the 20-degree rule of air conditioning states that you should always keep your AC unit at no more than 20 degrees lower than the outside temperature. It means that, if the outdoor conditions are at 95 degrees, you should set your thermostat at no less than 75 degrees.
Shade For Your Body
Even if a large canopy is only cooling the air by 5°F, it can make us feel upwards of 18°F cooler, because it can block about 90% of solar rays from reaching our bodies.
Reality: Contrary to popular belief, ceiling fans do not decrease the actual air temperature in a room. Instead, they generate a wind chill effect akin to the refreshing sensation of a breeze on a warm day. Enhancing sweat evaporation as air moves across your skin creates a sensation of coolness.
The U.S. Department of Energy (DOE) recommends aiming for an inside temperature of 78 degrees Fahrenheit in summer. In winter, the DOE suggests 68 degrees Fahrenheit as the indoor temperature to aim for, letting that drop lower when you are asleep at night.
Set the thermostat as high as comfortably possible during hot weather. The less difference between the indoor and outdoor temperatures, the lower your cooling bill will be. Keep your house warmer when you aren't home during the day, but cooler when you come home at night.
According to researcher Danny Parker from the Florida Solar Energy Center, who performed a two-year energy study, shading the unit provides “minuscule results at best” with efficiency being increased less than half a percent. While you may wish to cover your condenser since let's face it – they aren't very stylish!
Setting your air conditioning to 72°F is generally considered a comfortable indoor temperature for many people. It strikes a good balance between comfort and energy efficiency, making it a popular choice for residential settings.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
