An Energy-Efficient Aircon unit will Reduce Bills

This is not true, as even the most efficiently-rated air conditioners can cost more to operate, if they've been improperly installed or sized. Poor installation and improperly-sized equipment can cost you significantly in terms of energy consumption.

Lack of cool air

If you notice that your air conditioner is no longer blowing cool air or is not blowing much air at all, your unit may need to be replaced.

Increased bills

When your utility bills begin to consistently rise higher and higher than normal, you should call in a technician to see if there is a problem with your AC unit. This may be caused by a leak in your air conditioner's ductwork or a broken thermostat switch—or it could just be a side effect of your unit getting older.

Old unit age

If your air conditioner is older than 10 or 15 years old, you should consider scheduling AC replacement before it stops working or requires major repairs.

Odd sounds

If you begin to hear squealing, scraping, or grinding noises from you AC unit, there may be a problem inside the unit with a belt slipping out of place. You should call an expert immediately because this has the potential to lead to other major problems.

Frequent repairs

If you continue to spend more and more money on AC repair, you'll likely save in the long run if you replace your unit instead.

Leaking moisture

When water leaks anywhere in or around your air conditioner, you're likely dealing with a refrigerant leak. There is also a chance that this is just water leaking due to a blocked or broken condensation tube. Either way, you should call an HVAC contractor immediately.

Strange smells

If you smell something pungent coming from your air conditioning vents, this may mean that your unit's wire insulation has burnt out and you should invest in a new unit.

An Air-conditioner is just a Device that cools Air

Your aircon unit doesn't just produce cool air, but also plays a big part in reducing humidity. Imagine sitting in a cold yet clammy-feeling room! Humid air feels a whole lot hotter than dry air, so this is a necessary step – especially in Singapore.

No House requires more than 1 Thermostat

Even smaller-sized houses can benefit from installing more than 1 thermostat. This is particularly true for houses with downstairs living areas and upstairs bedrooms for instance, as it helps maximize energy savings. When it comes to comfort, this is a must.

The Thermostat is responsible for all Temperature Issues

If your house isn't being cooled to a desired temperature, it's not necessarily due to a faulty thermostat. The problem can stem from a fault within the cooling system, or even the ductwork. It's best to get in touch with a professional – to get to the root of the problem.

Leaving Doors open boosts Cold Air Circulation

It's better to close doors to improve efficiency. This helps cool rooms faster, and enables the unit to shut off more quickly. If you're using central air conditioning, it's best to install registers to help the system control the airflow to the rooms you occupy.

Replace Partial or Full Aircon System

The location of the Air Conditioner doesn't Matter

In order to maximize efficiency, make sure the outdoor unit is not exposed to direct sunlight. Also, if you plant shrubs or creepers around the outdoor unit, ensure that you don't block the airflow around the unit. The location of the thermostat also impacts how long the unit will run for.

You should get the Biggest Air Conditioner you can Afford

A properly-sized AC unit fits your home perfectly, and doesn't have to be the biggest. Take into consideration things factors such as insulation, windows, air leakage, roof characteristics, etc. An air conditioner that fits the house will not only run longer, but also keep the occupants more comfortable and utilize less electricity. 

Save Money & Energy by Turning off the AC (while away)

It's more efficient to leave your air conditioning running when you're not at home than it is to turn it off and re-cool your house when you get home. This forces your air conditioner to work a lot harder when it's turned back on. An energy-efficient programmable thermostat lets your house warm up when you're gone, and cool things down before you get home.

Air Conditioners use too much Energy

The fact is that air conditioners are now required to come out with star ratings and technologies that greatly reduce energy costs. One pro tip: Ensure that your aircon is installed properly, as studies have shown that improperly-installed duct systems can impact energy efficiency.

Regular Aircon Servicing is not Necessary

Not true! Just like cars that hit a certain mileage, air conditioners too need regular servicing. This is done to identify and fix any machine issues – to help it run more efficiently. Remember that early detection can help prevent expensive repairs in the future, thus saving you more in the long run.

Save More by Using a Fan & Aircon Simultaneously

The opposite is true. Most people don't realize that fans don't cool the air, but merely move the air around. This makes you feel cooler, but doesn't help cool your room any faster. Using an aircon and fan at the same time will actually drive up your utility bill.

Air Conditioners cause Arthritis/Colds

Any doctor will tell you that people don't get sick from temperatures but from viruses. Many people believe that cold temperatures can cause illnesses, which is untrue. Extremely hot or cold temperatures can aggravate existing conditions, as extremes of any kind are unhealthy.

Set the Lowest Temperature to Speed Up Cooling

Be it 25°C or 18°C, your air conditioner produces cool air constantly. The temperature you set may vary, but ultimately the time taken to cool down your interiors is the same. You might as well set a higher temperature to cool your room efficiently. Who knew, right?
