Why would an air conditioner run continuously? According to HVAC professionals, there are many reasons why an air conditioner might run continuously, including frozen coils, inadequate airflow, and high outside temperatures. Contact a professional to troubleshoot a specific system. What are some tips for buying an air conditioner? What are some DIY air conditioner repairs? One reason an air conditioner runs constantly is that the thermostat is set too low for the outside temperature. An air conditioner can only effectively cool outside air by 20 to 30 degrees, so when the outside temperature is over 100 degrees, an air conditioner will run constantly if it is set to 65 degrees. If the air conditioner's coils are dirty, they can freeze up. This leads to inadequate cooling and a continuously running air conditioner. The coils can also freeze when the filter is too dirty to allow adequate airflow.

For many, it’s even worth the increase in your utility bills. However, an AC unit that’s constantly running, even after your home has reached it’s desired temperature, is an unnecessary expense, not only in utility bills, but also in increased wear-and-tear on your system. So why is your air conditioner constantly running? The experts at Supreme Air have seen this problem numerous times. Here are a few possible reasons:

Air conditioners can be powerful, but they can only cool your home so much. If there’s a large difference between the temperature outside and the temperature you want your home to be, your air conditioner will run constantly in a futile attempt to reach the temperature set on your thermostat. A 20 degree difference is all you can really expect your AC to achieve. To relieve your AC unit, you need to increase your thermostat setting to something more reasonable. If it’s 100 degrees, setting your thermostat to 72 degrees is too drastic of a difference for your unit to achieve.

To make up the difference, it will run constantly to keep your home at a comfortable temperature. You’ll eventually have to purchase a new air conditioner more suited to the size of your home – and sooner rather than later, as the extra strain will shorten the lifespan of your current unit.

AC units typically last up to 15 or 20 years, but after 10 years you might see a decrease in performance quality. A new unit will have fewer problems and run more efficiently than an outdated model.ceiling ac unit If you have issues with air flow, cool air won’t be delivered properly to your home. auxiliary ac unitIf this is the case, your AC unit will work constantly, but accomplish very little. wall ac and heating unitTo avoid this, make sure that your AC unit is regularly cleaned of dust and debris. We suggest replacing your air conditioner’s air filter every month during air conditioning season. In order to cool your air, the air is blown over coils, which remove heat from the air. If there is dirt or ice built up on these coils, they won’t work as efficiently, making your AC unit run harder and longer.

See a technician if you think your coils are to blame. Refrigerant runs through your AC’s coils to remove heat from the air. If there is a leak, your AC won’t have enough refrigerant to sufficiently cool the air. The system will continue to run, trying to satisfy the thermostat setting. Speak with a technician to see if low refrigerant may be the problem.

The principle behind air conditioning is simple. Two coils (one inside your home, the other outside) are connected by pipes filled with refrigerant. This fluid has the property of easily absorbing and rejecting heat, and is pumped through this circuit of pipes by a compressor. Two fans pass air over these coils.During the cooling cycle, warmed refrigerant circulates through the outside coil where it releases heat and cools down.

It moves back inside, and is circulated through the indoor coil.The hot air inside your home is blown over this cold coil (and filtered and dehumidified at the same time) where it cools down and, in turn, cools your home. During this process the refrigerant warms up and moves back outside to repeat the cycle. (Your domestic fridge is a good example of this process.) When heating your home, warmth is generated by ‘reversing' the operation of the air conditioner. Instead of expelling the hot air and circulating cool air it does the reverse - hence the term ‘reverse cycle' air conditioning. Where to locate your Air Conditioning unitTo ensure optimum performance, single package units or the outdoor section of split systems should have adequate ventilation and, if possible, be placed in a shady area.Direct sunshine and restriction of air access will reduce the air conditioner's performance.Adequate clearance from obstructions is essential to ensure that exhaust air is not re-circulated back through the outdoor coil.

Saving EnergyGenerally the best temperature to set your air conditioning to is around 24 - 25°C in summer and 17 - 19°C in winter.You can save considerably on the amount of energy consumed for each 1°C of cooling or heating that you do without. For example when it's 35° outside, setting your air conditioner to around 25, rather than say, 22, can save a significant amount of energy without your system running constantly. Balance between comfort and efficiency of the system.Shade your windows in summer with curtains, awnings, or shutters to reduce heat absorption by up to 80%. Heavy linen curtains with pelmets will also help trap heat in winter. This all helps in reducing the overall running costs of your air conditioning..au Caring for your Air Conditioning unitAir conditioning maintenance is always based on individual use, but in general you should check filters once a fortnight and replace the batteries in your remote control (where applicable) once a year. At the same time check the outdoor unit is clear of leaves, shrubs or dirt build up.

To clean, simply brush or hose the outdoor coil. Please read the filter section below for more information. FiltersThe primary purpose of filters is to protect the indoor coil from dust build up which could reduce the overall performance of the air conditioner. It is important to regularly check and clean your filter. The majority of service calls are due to a dirty or blocked filter and in most cases a service fee is charged even if the air conditioner is under warranty.Most air conditioners in the split range now have a specially treated additional filter that traps fine pollens etc which greatly helps people suffering from allergies.Ducted systems can now have electrostatic air filters fitted, which is the ultimate in home or office filtration.Air conditioning maintenance is just one simple fortnightly operation. Because the air filter in any air conditioner screens out dust and pollen particles, it should be removed regularly and washed. This simple operation is covered in the individual unit's instruction manual.
