Could a Wristband Replace Air Conditioning?

It is unusual to assume that again within the mid-1960s, residence air conditioning was such a luxurious that solely 10 p.c of American properties had been equipped with it. Some families within the South actually slept on their porches to cope with summer time heat [source: Oremus].

In the present day, practically everybody in the U.S. annual household electricity use [source: EIA]. In 2013, Individuals spent $7.2 billion putting in or changing central air conditioning units in their houses, in line with federal census data. That was more than another sort of dwelling enchancment, besides for new kitchens and bathroom remodeling, in line with the survey [supply: Quint]. News reviews recommend that air-conditioning restore services are regularly busy fixing or changing tools for overheated homeowners. has it. Nine out of 10 American homes are now geared up with some type of air conditioning, and residential air conditioning accounts for an estimated 18 % of U.S. One Indianapolis-primarily based repairman, for instance, told a neighborhood Tv station in Could 2018 – a document-breaking sizzling month in that area – that he had been working six days a week, up to 14 hours a day, responding to calls for repairs [supply: Houser].

Listed here are 5 reasons that your AC might stop working this summer time, and what you can do to keep it going.


Mechanical Issues

Clogged Air Filter

Low Refrigerant

The Out of doors Condenser Unit is Blocked

The Unit Is simply too Small or Has an Previous Thermostat

5: Mechanical Points

An air conditioner’s job is to do away with the heat inside your private home and herald cool air, with the help of a chemical called refrigerant. AC methods have mainly 5 components:


Evaporator coil (cools the air)

Compressor (electric pump)

Condenser coil (transfers heat)

Enlargement gadget

Air conditioning units have two elements: one inside your own home and one outside of it. If the motor on your fan is not working, the out of doors unit cannot do away with the heat. The expansion valve regulates the amount of refrigerant moving between the evaporator and condenser coils. If your compressor is broken, the refrigerant can’t circulate between the inside and outdoors models [supply: Coolray]. In the meantime exterior, the compressor, condenser coil and one other fan vent the hot air coming off the refrigerant. A fan in the inside unit blows air through the chilled evaporator coil, cooling your house, by way of air ducts.

Replacing a few of these components is very costly (notably the compressor) and is probably not a lot cheaper than changing the entire unit. Having a trained technician give your unit a yearly checkup ought to forestall premature mechanical failure.

“Residential central air conditioning units are extraordinarily dependable, which is why homeowners usually overlook to carry out routine maintenance on them,” says Francis Dietz, vice president for public affairs for the Air Conditioning, Heating and Refrigeration Institute, says in an electronic mail. Nevertheless, these units “require attention for them to perform properly.”

Which brings us to the second drawback on our record.

4: Clogged Air Filter

Dietz says failure to replace the air filter on schedule is considered one of the most common reasons that an AC unit will stop working. “Homeowners who ignore this basic activity, danger on the very least make their unit work harder than obligatory just to try to push the cooled air by a clogged filter,” he notes.

“In excessive – but not utterly unusual – cases, a unit will be completely incapacitated and have to be replaced as a result of the cool air, having nowhere to go, circulates again into the evaporator coil, inflicting it to freeze and fail,” he adds. The evaporator coil is a network of tubes, filled with a coolant called refrigerant, that take away moisture and heat from the air. Client Experiences recommends that filters on central air conditioning units be modified once a month, especially when you have the air conditioning running continuously, or have pets who shed fur.

To make it easier, Dietz says, a lot of at the moment’s advanced thermostats automatically notify homeowners of the necessity to exchange a filter.

Cooler box3: Low Refrigerant

Inside your heat house, cold liquid refrigerant evaporates on the evaporator coil, turning into gas. The new refrigerant fuel is then pumped outdoors into your system’s condenser, where it transfers the heat to the surface air and reverts right into a liquid again and the cycle continues [source: DOE].

As you can think about, if the refrigerant is low, the air conditioner will not cool very well. One is that when the system was put in, not enough was added. However more doubtless, the level is low as a result of your system has developed a leak.

Leaks are the reason for 90 percent of the instances of low refrigerant [supply: ServiceExperts]. So, simply adding extra refrigerant isn’t going to fix issues. After the restore is tested, the technician can cost the system with the correct amount of refrigerant and your system needs to be set. Bring in a trained technician to search out the leak and fix it.

Nearly all present AC methods use halogenated chlorofluorocarbons (HCFCs), aka R-22 or freon, as a refrigerant however these are being phased out for environmental causes. Between 2020 and 2030, ozone-safe hydrofluorocarbons (HFCs) are anticipated to grow to be the norm [source: DOE].

2: The Outside Condenser Unit is Blocked

Careless outside landscaping and/or neglect of lawn care could also be one other motive that your house is so hot.

“Shrubs and other plant life can obstruct airflow to the [out of doors condenser unit], which relies on it for correct operation,” says Dietz of the Air Conditioning, Heating and Refrigeration Institute.

“Homeowners ought to take care to ensure an honest-sized berth round and on prime of their outside unit and likewise periodically use a garden hose (not a stress washer), to remove dirt and debris that may be caught within the unit’s fins,” says Dietz. “Lawn clippings and dirt kicked up by heavy rainfall are widespread culprits right here.”

Consumer Studies recommends permitting 2 to 3 feet (60 to 91 centimeters) of house between the unit and any plants or backyard buildings, and 5 feet (1.5 meters) between the top of the unit and any trees that hang over it.

1: The Unit Is just too Small or Has an Previous Thermostat

One big motive for malfunctions is that loads of home air conditioning programs aren’t put in accurately in the first place, says Todd Washam, director of industry and external relations for the Air Conditioning Contractors of America, a trade group that represents about 4,000 contractors throughout the U.S. and writes standards and manuals for the trade.

Washam says that it’s essential for installers to make careful calculations beforehand on how much cooling a house will need, and to make it possible for the air conditioning unit is matched with correctly-sized ducts. If the ducts are too small, he says, the unit should work harder to cool down the house. Some of the new units can even be programmed remotely utilizing your smartphone or tablet, which is a nice convenience. If one thing is improper with your thermostat, your air conditioner won’t get the mandatory directions on how much to cool your own home. And if the unit itself is simply too small for the house, the home won’t ever get cool enough. That, in flip, will increase put on and tear on the elements and shortens their lifespan. Treatment the issue by both having the thermostat recalibrated by a technician, or replacing it with a newer programmable digital unit, which can be extra precise and show you how to to avoid wasting energy as properly.
