Benefits of Central Air conditioning Hawaii

Benefits of Central Air conditioning Hawaii

What are the differences and benefits of a central air system? The best air conditioning system is the one you don’t have to think about. It comes on the moment the indoor temperature set on the thermostat requires cooling performance, and then runs quietly and efficiently when needed.  But when it’s time to perform routine maintenance, make repairs or replace your system, it’s helpful to understand how an air conditioning system works.

How does a Central Air system works?



The Refrigeration Cycle

    1. Using electricity as its power source, the refrigerant flows through a closed system of refrigeration lines between the indoor unit and the outside unit.
    2. Warm air from the inside of your house is pulled into ductwork by a motorized fan.
    3. The refrigerant is pumped from the exterior compressor coil to the interior evaporator coil, where it absorbs the heat from the air.
    4. This cooled air is then pushed through connecting ducts to vents throughout the home, lowering the interior temperature.
    5. The refrigeration cycle continues again, providing a consistent method to keep you cool.

Pro’s: Benefits of central air systems?

  • Pro: Consistent temperature all year long
  • Central air conditioning helps keep your home cool and reduces humidity levels
  • As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply duct-work that carries it back to rooms.
  • Quieter: the compressor-bearing unit is located outside the home, the indoor noise level from its operation is lower than that of a split air conditioning


  • Con: Need for ductwork: if you don’t have it yet – consider the fact installing ductwork is a major renovation that involves opening up walls and floors. Although it’ll certainly increase the value of your home in the long run, it’s a major investment that’ll require planning and a good budget.
  • Consider it carefully

    Central air is a great choice for general comfort and energy efficiency. Multiple window units are definitely less efficient than a single, central system that controls the entire home. However, concerns over budget, ductwork installation and maintenance, and increased energy bills can be major obstacles.

Cost to Install Split System Air Conditioner Hawaii?

Cost to Install Split System Air Conditioner Hawaii?

Any ductless air condition installation is going to demand a qualified installer. For this question, we will consider the costs of installing a ductless or “split” air conditioning system in a 1500 square foot home. The average price for the equipment and installation of a system sized appropriately for the cooling needs of a home of this size in Hawaii ranges $3500-$10,000. This would include the outdoor condensing unit and the air handlers as well as the necessary lines, but does not differentiate between single, double, triple or quad zone systems.

Cost breakdown single zone split AC System

Split AC system 36,000 BTU (compressor, air handler and lineset) $ 2499
– Electrical work $ 400-500

Additional costs

The costs given do not include such things as the addition of heating functions and lines, the removal of old equipment, and the managing of existing ductwork that is no longer required. These would vary from project to project, but must be taken into consideration when developing the budget.

Installers may increase costs if attic or basement space is very difficult to work in, or if special efforts must be made to get supply lines to the area of the rooms in which the air handlers will be mounted. The air handlers are mounted high on a wall or in the ceiling per the choice of the homeowner, and there are no costs differences in equipment selection.

What is a BTU?

What is a BTU?

A BTU, short for British Thermal Unit, is a standardized measurement of energy. Technically, 1 BTU is roughly equal to the amount of energy required to raise 1 pound of water 1 degree F.

In North America, the BTU is used to describe both the heat content of fuels and the power of heating and cooling appliances such as furnaces, air conditioners, water heaters, stoves, fireplaces, and barbecues. When used as this type of measurement, the term “BTU” actually refers to BTUs per hour (BTU/h).

When buying a heating or cooling appliance, be sure you understand whether the stated BTU capacity refers to the unit’s input or output. An input BTU refers to the fuel used; an output BTU measures the heat (or cooling) created.

In some cases, it’s necessary to convert BTUs into another form of measurement. Here are a few helpful conversions:

• 1 BTU equals 252 to 253 calories
• 1 BTU equals .293071 watt hours
• 1 watt is approximately 3.41214 BTU hours
• 1,000 BTU hours equal approximately 293.071 watts
• 1 therm equals 100,000 BTUs
• 1 “ton” of cooling equals 12,000 BTUs per hour
• 1 standard cubic foot of natural gas yields 1,030 BTUs

AC energy-saving tips Hawaii

AC energy-saving tips Hawaii

Follow the tips below to increase energy efficiency and save money.

1. Leave most of the air vents open in your home. Closing air vents in more than 10% of your total conditioned space creates a pressure imbalance and reduces the effectiveness of your cooling system.

2. Do moisture-producing chores when it is cooler and your cooling system won’t have to work as hard. Wash clothes and dishes or mop floors in the early morning or at night. If you are on an SRP Time of Day Price Plan , doing laundry during the off-peak hours will help you save money.

3. Prevent heat gain inside the house by taking these steps to lessen the load on your cooling system.

4. Air conditioners and heat pumps

Set the thermostat between 78 to 80 degrees when you are home and up to 85 degrees when you are away. For every degree you set your thermostat above 80 degrees, you can save approximately 2 to 3% on cooling costs.

5. Install a programmable thermostat.

Set it to allow the temperature in your home to increase by 5-10 degrees while you’re away and to return to a comfortable level an hour before you return. If you are on an SRP Time-of-Day Price Plan, set the thermostat to return to a comfortable level during off-peak hours.

6. Turn your air conditioning fan to “Auto.” This turns the fan motor off when the unit is not cooling. Using “Auto” rather than “On” can save you $15 to $25 each month on your energy costs.

7. Schedule maintenance service on your cooling system once a year by an SRP Certified Contractor to maintain its efficiency.
Buy a higher-SEER unit when the time comes to replace your cooling system. The efficiency of heat pumps and air conditioners is indicated by the Seasonal Energy Efficiency Ratio (SEER). The higher the number, the more cooling you will get for your dollar. Ask a qualified air conditioning contractor what level of efficiency is right for your home.

8. Buy the right size cooling system.

A unit that is too large for your house will cause frequent cycling, inefficient operation and higher operating costs.

9. Set your ceiling fans to blow downward during the summer to circulate air rather than lowering your thermostat.

10. Clean debris and obstructions from around outdoor air conditioning components.

11. Replace disposable air filters or clean permanent ones at least once a month. A dirty filter forces your equipment to work harder, causing higher energy bills.


Ten energy saving tips

Ten energy saving tips

To help keep your bills and your energy consumption as low as possible, check out the 10 tips below:

1. Warmer At Night Is OK: During the night time hours you don’t require the same level of conscious cool. Try turning your AC down (so it is running less) during your sleep hours or an hour or two before bed.

2. Close Off Vents: The basement is traditionally the coolest room in the home, so try closing all the vents in the lower portion of your home. The cool air will slink down there naturally and by closing those vents, you’re forcing all the air up top first, cooling as it comes down.

3. Service Your Unit: Some basic maintenance might be all your air conditioner needs, but most will greatly benefit from a good hosing out, especially if you’re plagued with pesky trees like Cottonwoods that drop seeds which stick to the filters and make the unit work 15% harder!

4. Check Your Ducts: Making sure the areas where your ducts run through parts of your home without air conditioning (like the attic) are properly insulated will keep the air coming in as cool as it can be. Paying for half cool air isn’t anyone’s idea of money well spent!

5. Rearrange Your Furniture: Furniture that obstructs air conditioning vents means you could be cooling the back of a chair or the bottom side of your sofa and although it might appreciate the thought, we’re pretty sure you’d rather have that chill instead. Although they make plastic pieces for your vents to help force air in the right direction, the easiest way is to just rearrange things for awhile!

6. Try 78 Degrees: 78 degrees is a good point for an air conditioner to run at its optimal performance level. Think of it as a car on cruise control headed across the flat Midwest prairie. It’s not chugging along going up hill, and is just is plugging away, steady as she goes. Taking your temperature even 5 degrees lower can make your air conditioner use up to 40% more energy!

7. Lighting: Turning lights off can help reduce your heat, but paying attention to how much light you let in from open windows can also play a significant role. Although it might neurotic to open and close your windows everyday with the changing of the sun, it makes a huge difference in how much heat your bought air is competing against.

8. Is Anyone Home?: If you can, while you’re away turn your AC up to 85 and make sure the windows and drapes are closed. Although it will be hot for a few minutes when you come home, the blinds will help keep out the sun out (allowing existing cool to stay that way for as long as possible) and the heat won’t be so substantial that your unit will have to work overtime to cool things back off.

9. Don’t Forget The Fan: We rely on air conditioners to keep things cool, but having the help of a few supplemental fans doesn’t hurt. Using them to circulate the cool air means you don’t need quite as much pumped into the room. They use less energy than your air conditioner unit, so having them around as backup is a great idea.

10. Buy Energy Star: Whether you’re buying a central air conditioner (which could qualify for a tax credit) or a room unit, efficiency matters. An Energy Star central air system will use about 14% less energy than minimum government standards, and a room air conditioner will save at least 10%.
