Air Conditioning Sizing

Sizing an AirCon to Stay Cool and Save Money this Summer

When it comes to AC size, should one go big or go small? Read on to decide.


Buying a higher capacity aircon is more expensive upfront, аnd саn unnecessarily run up your power bills during the summer. Еvеn wоrsе, it can leave your house humid. A small AC саn be a problem too. It works too hard tо cool a space аnd you still end up with high electric bills. An air conditioner that’s just the right size is what suits your home best. Study the guide below, but if you’re after more specifics, visit this Sydney A/C website.

DO THE MATH

AC cooling capacity is mеаsurеd in British Thermal Units, or BTUs. Yоu may also hear the term “tons”, which is thе equivalent of 12,000 BTU’s. Whilе it’s not necessary to understand thе science behind it, yоu should have а good grasp of capacity in relation tо the square footage yоu need to cool.

First, find out the area оf your room by multiplying its length by its width. For oddly-shaped rooms, rеасh back to the basic principles yоu learned in geometry class. Оnсе yоu’vе determined the entire square footage of your home оr the room you plan to сооl, multiply it by 25 BTUs. Thе resulting number is thе required capacity.

Keep in mind thаt this is a very rough estimate. It’s рrеtty adequate for sizing a room air conditioner, but other factors can also affect AC size.

  • For a heavily-shaded room, rеduсе the BTU capacity by 10%. If it’s sunny, inсrеаsе it by 10%.
  • If more than two people occupy a room regularly, add аn additional 600 BTU for each extra person.
  • Kitchens produce a lot of heat, sо add 4,000 BTU to your total.

OTHER AC CAPACITY FACTORS

When buying a new central AC, consult an HVAC specialist оr a large home improvement store thаt handles installations. Professionals use the sсiеntifiсаlly ассurаtе “Manual J” method tо determine the right AC size. Still, it’s а good idea to bе familiar with the factors involved.

The size of your home is оbviоusly one large factor in determining the right sizing. Equally important are other factors thаt often get overlooked:

  • Consider your home’s orientation rеlаtivе to the sun.
  • How well it’s shaded, taking into consideration the type of trees.
  • The number and size of windows аnd which directions they face.
  • How well your walls аnd air ducts are insulated.
  • Consider any major changes yоu plan to make to your house – adding skylights, large windows or another room. This will significantly add to your AC needs.

Play around with an online calculator tо get a general idea оf how all these factors come together.

IN CONCLUSION

Determining AC capacity is a critical move before purchasing and installing any unit. Once a unit is installed, it’s a permanent fixture, so get it right the first timе. If your air conditioner is brand new оr you’ve just moved into a new араrtmеnt, learn how to calculate the proper size. A рrореrly sized AC rewards you with energy savings аll summer long.

HVAC contractors need to have good reputations in the market. The person must have earned great respect from people they served in the past. Look for companies that have no complaints filed against them by past customers. You can ascertain this by visiting their business websites to see how they have been reviewed by those who they worked for before.

A reliable contractor must have undergone proper training. These professionals attend technical institutions to acquire skills and knowledge. A highly knowledgeable contractor can fix the problem with your AC unit fast and efficiently. This is because they have been trained on the same. Always ask to see the qualification certificates they have before making that vital decision of hiring.

The provider you need to hire ought to be licensed and insured. These credentials are extremely vital. The contractor should be licensed to work in your area.

A/C Maintenance

Tips for an Air Conditioning Tune Up

By following these A/C tune-up tips, you can keep your home cool and utility bills low during the oppressive summer heat. The key is making sure that your air conditioner is working efficiently.

It’s not difficult to keep cool during sweltering months without receiving high utility bills. Whether you have a window unit or a central air system, there are ways you can cool down all summer long and save money while at it.

Air Filters

Your air conditioning unit will work without hiccups if it’s fully clean. If the air filters are dirty, clean or replace them. We recommend cleaning once every month and replacing once in a 90-day period. Replace the filters frequently if your home is always dusty or you have pets because dust and pet fur build up in the filters.

Go “Auto”

Set your thermostat to the auto setting. In auto mode, your air conditioner won’t run non-stop. This reduces the amount of energy needed to keep the unit up and running.

Hour after hour, your air con circulates air in your home and removes moisture from it. When running automatically, it will shut off when the desired temperature is reached.

A/C Maintenance

On the outside unit, there’s a condenser coil that you should wash. Clean it once a year for your air conditioner to run at peak efficiency. A dirty coil is less efficient and runs hotter.

To tell if the coil is running too hot, check the copper tube connecting the indoor and outdoor units. If it is, professional service is in order. An air conditioning technician will inspect the unit for low refrigerant levels and clean it. Full of refrigerant and free of debris, your A/C will run smoothly come summer. Accutemp are professionals who highly recommend getting your A/C maintained regularly. They specialise in commercial air conditioning Adelaide services as well as a range of other HVAC related services. Learn more at Accutemp’s Facebook on A/C maintenance.

Home and Away

Always leave the air con on when going out, even if you’re going on vacation. Turn the unit off and it will strain to cool your house when you restart it. In addition, plants, pets and appliances may suffer if it gets too hot indoors.

Instead of turning the air conditioner off, be energy-efficient by raising the temperature. An increase of 10 degrees will ensure that your home doesn’t heat up, forcing your A/C to work harder and longer to bring the mercury down.

Programmable Thermostat

Save 5-30% on energy use using a programmable thermostat. Set the thermostat to a higher temperature, say 26oC, at night and when you’re off to work.

Smart thermostats are a better option. You can program the thermostat as you wish and control it from your phone or tablet wherever you are. For max efficiency and personalised comfort, go “smart.”

Expert Touch

Staying cool in the summer is an obsession for many. But it can drain your time, wallet and productivity if your unit isn’t running reliably. When your air conditioner goes on the fritz, call in an accredited HVAC specialist. An expert technician will respond in time and give you a prompt, reliable service.

Do it yourself air conditioning is money-saving but time-sucking.

Cheap Air Conditioning

Cost-effective Ways to Keep Your Home Cool

Cooling a home can be tricky. While air conditioning can do that, it can be too expensive. So how can you make your home a cool haven without breaking the bank? Below are ideas that will cool your home and save you money.

Natural Cooling

Air conditioning fights hot air coming into your home. Sources of the hot air are dark walls, poor insulation, lack of ventilation and light through windows. These problems you can overcome economically. Ceiling fans are cheaper than air conditioners and perfect when the temperature isn’t too high. If direct sunlight pours into your home through a door or window, consider installing awnings.

Install an openable skylight to expel hot air through the ceiling. Make use of cross ventilation to bring cool air into your home. Light coloured walls will reflect heat away from your house, but dark colours absorb heat and transfer it indoors. Good interior ventilation will cut air conditioning costs in the hot summer months.

Types of Air Conditioning Systems

Portable air conditioners are appropriate for a small room or apartment but expensive to run. Wall or window air conditioning is effective, but bulky and only cools one room. A better choice may be a split-system air conditioner, which has an indoor cooling unit connected to an outdoor unit.

Ducted air cons are great for cooling but cost a lot. Look at the Star rating on a ducted A/C. The higher the Star rating, the more you will save because the air conditioner will be more efficient. Evaporative coolers cool air using water and are the cheapest to run.

Size of an Air Conditioning System

The size of an air conditioner matters and getting the right size will save money. A system that’s too small for an area will cost more money as it has to work harder. Buying the right-size air conditioning unit is costly initially but cost-effective over time.

If your home has high ceilings, you need a higher capacity unit and an air conditioning specialist can suggest the right size. According to air conditioning Canberra, since not all rooms are of the same size, get a unit that can cool the largest room and use a zoned system that lets you turn off the air con in rooms you’re not using. See more from Southern Aircon & Refrigeration with their featured article on getting the most out of your air conditioner.

Save Money Cooling Your Home

Natural cooling methods can reduce air conditioning costs. Another smart way to lower costs is turning up the thermostat on your A/C. For every degree you raise the thermostat, you can potentially save 10-15% on energy bills.

Other ways you can maximise your air conditioning include: Servicing your unit regularly to ensure it’s working properly and efficiently. Turning off lights and making sure sunlight isn’t streaming through the windows. Using a ceiling fan instead of an air conditioner if the weather isn’t too hot or running both on hotter days.

Lastly…

Air conditioning alone can cool your home but is rather costly and unhealthy. Look for natural ways and use them as often as possible. You will feel healthier and your wallet will thank you.

Air Conditioning – Why Filter The Air

It might seem obvious that air filters (air conditioning or furnace filters) should be used but let’s look specifically at why that is so. Perhaps the most important reason to try to clean the air is the health aspect. Studies have shown that interior air is frequently more polluted and harmful than outside air. That may seem counter-intuitive to most of us because of two factors. The first is that interior air usually “looks” clean, in that it does not appear dirty like the air in a smog filled city might. Also, assuming reasonable cleanliness, most interior air does not contain strong odors which we usually associate with pollution.

Having said that, the obvious exception is when cigarette, pipe or cigar smoking occurs on a regular basis. Now the pollution can’t be missed, you can see it and you can smell it. The health concerns regarding smoking are well known and possibly beaten to death, so we won’t get into that. Not so obvious is the health impact of dirty interior air when we don’t notice it. Medical experts have concluded that symptoms ranging from headaches, asthma, bronchitis, allergies, and cancer among others, may likely be attributed to polluted interior air.

The next reason to use a furnace filter or air conditioning filter is to keep your heating and cooling system operating as it was designed and to prolong its life. For an air conditioning unit to operate at its peak efficiency it needs to be kept clean. The evaporator is the component in your system in which the air passes directly over and is cooled and returned to your living space. The surfaces of the evaporator are normally very cold and therefore wet with condensation. The moisture in the air condensates on the evaporator and subsequently drains to the exterior of the building. Imagine blowing dirty air across the cold wet surfaces of the evaporator. How long do you think it takes for the dirt to completely cover this wet surface? Once dirty, the evaporator loses efficiency and may begin to support mold and bacteria growth, after all, it is a dark moist environment.

The last reason for using an air conditioning filter and furnace filter is to help keep your house clean. Look at it this way, every time your air conditioner or furnace runs it is like someone is vacuuming the air of dust, dirt or worse. All of this for only a couple bucks per month seems like an obvious choice, your air must be filtered. What may not be obvious is which furnace filter and air conditioning filters should be used, we will try to help with that decision.
