"This is an excellent young company whose owners are professional and responsible. They used to work for a large company that our old central air condo uses but unlike THAT company, these guys are HONEST and actually do the work at a fair price! I called 8 other companies and had 2 other companies to our condo and they did absolutely nothing except charge me for work that they should have done. Chris and Steve did all the maintenance and cleaning work on 4 central air units and discovered a ticking time bomb in the master bedroom right over hubby's work closet. The overflow sensor was not working, and the pan was full to the lip and would have ruined everything in the closet and the teak floors below. These guys will be back on a regular basis with us and hopefully our condo association will be open to spreading the word amongst the residents who are getting ripped off by the other companies who are often here."

"Jae was professional, friendly, and incredibly knowledgeable. He quickly diagnosed the issue as a faulty fan, explained everything clearly, and ordered the necessary part right away. As soon as the part arrived, Jae called me to schedule the installation and had my AC back in top shape in no time. His efficiency and dedication were impressive, and he even took the time to inspect the entire system to ensure it was running smoothly. Highly recommend JK AC Service."

"Jonathan was the first Plumber who was at our home in Pearl city he was very competent and fair. And did a great job. He also explained to us very well how the very old waistline pipes were clogged with corrosion over over 65 years and gave us a quick and fair price to do more aggressive cleaning of the main waistline to the street. Steve’s brought over a very experienced waistline Cleaning Employee who did I terrific job of descaling the old pipe and saving us thousands of dollars. We have few thieves for HVAC and plumbing and have always been happy with their fairness, communication, and service. We will continue to use them and are always amazed at their service. I would highly recommend their Plumbers. They also are quick!"

"The technician from Air Conditioning Concepts showed up on time and got started immediately on checking and cleaning our split AC units. We have a mix of old Friedrich and newer Mitsubishi units, and he knew how to service both with no problem. He was able to get 2 of the old units up and running by adding coolant to both and retaping the wiring on one of them. Throughout the process he was very polite, had a positive attitude and took the time to talk to us about the age and duration of our units, what he found while maintaining them, and how he fixed them. Mahalo Juvanny!"

Heating and Air Conditioning questions, answered by experts

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.
