Do the systems come pre-charged?
Yes, all of our mini split systems come pre-charged with eneough freon (usually R410A) for the length of the included lineset (usually 25 feet). If the distance between the outdoor compressor and indoor air handler is longer than 25 feet, your HVAC installer will need to add additional freon at time of installation.
Do the systems come with installation kits?
Many of our package systems come with an installation line set, copper piping and other accessories required for installation. It is important to check the listing details to see if your system comes with these accessories. A multi-zone system where the sets are included will come with an installation kit for each air handler. For example, a tri-zone system come with 3 install kits. The length can be anywhere from 13′ to 25′ per run for our pre-packages where sets are included. The piping can be extended by purchasing additional piping – flares – couplers etc. at home depot or any local plumbing supply store. We also stock additional 16′ & 25′ lengths if you want to splice 2 line sets together to form longer runs.
How big will the hole in my wall be?
Generally, a hole 3″ or less in diameter is all that is needed to run the refrigerant and connection lines from the outdoor condenser to the air handler mounted inside.
What are the pros and cons of a mini split air conditioner?
- Less Complicated & Less costly to install than central air
- The noisiest components (compressor fan - condenser motor) are isolated outside freeing indoor space and reducing noise pollution
- The most effective and efficient “add on system” available
- Unlike Central Air, gives you the option of specifying which areas to receive the most / least benefit.
- Matches the effectiveness of central air without the expense of retrofitting ductwork.
- Instead of large, bulky exhaust hose, only a small 2-3 inch hole is made in the wall to connect indoor and outdoor units.
- More Advanced installation that Window-Portable Air Conditioners
- In most cases, requires an HVAC technician to conduct or complete the final steps of the installation.
- Unit is more expensive than Window or Portable AC’s of similar cooling / heating capabilities.
- Considered a Permanent Installation relative to Portable units.
How to I Choose the right size BTU Split Air Conditioner Hawaii?
Like all air conditioners, you need to know how many BTU’s accommodate the area you are trying to cool. It is important to remember that Ductless Splits cool – heat a larger area for it’s BTU capacity than Portable or Window Air Conditioners. The Below BTU key is good general guide for gauging zone capacities.
- 9,000 BTU: 350 – 400 square feet
- 12,000 BTU: 450 – 600 square feet
- 18,000 BTU: 650 – 900 square feet
- 24,000 BTU: 900 – 1150 square feet
- 30,000 BTU: 1200 – 1350 square feet
- 36,000 BTU: 1400 – 1600 square feet
- 48,000 BTU: 1800 – 2400 square feet
- 60,000 BTU: 2500 – 2800 square feet
How do I pay for my new system?
For installation, we do not require any down payment, however we ask for payment the day we complete the installation (unless other arrangements have been made in advance).
For new equipment (the ac system) we ask for a 50% downpayment.
We accept cash, checks and creditcards. You can pay online (website) or on location with one of our reps (mobile payment).
If I call, can I have a quote emailed to me?
Yes, you can receive a quote via email, over the phone or in person.
Why should i buy a multi zone AC System Hawaii?
A multi zone AC system is designed for the many ways you use your home. Maybe you have unoccupied areas that do not need conditioning. A multiple zoning system allows you to divide your house into separate areas, giving you the comfort and control you’ve always wanted.
The main benefits of zoning are:
Zoning meets the specific temperature and airflow requirements of one area, without affecting other areas.
A zoning system can save you hundreds of dollars in energy costs each year.
Zoning divides a space into different areas and comfort into different levels, giving you more choices and control than ever before.
Multi zone AC system allows your cooling equipment to deliver peak performance and efficiency without continually operating at peak capacity. Lower speeds mean lower sound levels and lower costs.
How does an air conditioner work?
An air conditioner seems as if it cools the air, but it actually makes the space less warm by removing heat from the indoor air and transferring that heat to the outdoor air.
Heat is extracted by passing indoor air across a refrigerant coil in the indoor unit. Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.
What is SEER and ton?
SEER (Seasonal Energy Efficiency Ratio) is a measurement of a unit’s efficiency, and ton is a measurement of a unit’s size.
SEER (Seasonal Energy Efficiency Ratio) is a system for rating the efficiency of cooling equipment. The higher the SEER rating, the less your unit will cost to operate.
When should I replace my existing air conditioning unit system?
All systems and units are different. Here are some rough lifespan guidelines to help you decide whether fixing or replacing is the right decision:
- Average Lifetime of an Air Conditioner: 10-15 yrs.
Keep in mind that these are just guidelines. Some units last longer than that with regular maintenance and replacement of parts. But if a unit has been repaired repeatedly, or has been run excessively, it might make more sense to replace it even sooner. Paying for repairs to an old or inefficient system often simply prolongs the inevitable.
How important is it to get the right size of cooling equipment?
Sizing AC Systems is very important from the standpoints of both comfort and energy use. Heating and cooling equipment that are over-capacity will not run as frequently or as long when it does run. In both cases, this may mean poor humidity control. It could also result in temperature variations or noticeable cycling. Over-capacity equipment will not be as energy efficient as properly matched capacity either. On the other hand, equipment that is under-sized, will obviously result in loss of comfort during temperature extremes.
How often should I have maintenance done on my air conditioner?
You should have maintenance done on your air conditioning system at least once a year - spring to early summer being the best times. This not only ensures maximum efficiency, it enables us to foresee any possible problems that may occur in the near future.
What are the installation costs?
This depends on the situations of the house, the number and size of the rooms and your cooling wishes. Do it yourself or do the prep work will save a lot of money. But is not recommended if you have no technical experience.
A ball park figure / estimate for outsourcing the installation:
- Electrical work $ 200-400 (to run one dedicated line)
- Installation $ 250-500 (per single zone system – handler and compressor)
- Material cost (covers, extra wire, extra copper line) $ 100-200
Call or plan an free estimate online and we can tell you within 1 day (installation is done by an outside company)
What is the delivery time?
After payment we deliver within 5 days (Oahu). Express delivery: 1 day =$50. Pick up = Free (Kaimuki). Out of stock systems are delivered within 2-4 weeks.
