"Great Guy, Excellent Service, Quick, and Affordable. I chose this company to clean 3 a/c units as part of my move out inspection for my rental. They emailed me right away with a quote and even price matched. The guy that came out was super nice, explained what he was going to do and even provided me with an invoice with multiple pictures. I'm really glad I stumbled across this company. They made the move out process so much easier."

"Jason kept in touch with me until the assessment of the job. I sent photos of the old window units. He tried to figure out how much heat that needed to be removed from the space which included size of the room, heat making devices, sun on walls and windows. Light fixtures, fans and circulation within the space. Then calculated the BTUs required for each space. Then purchased the proper fitment for each space and the supplies needed to complete the job. Came back within ample time to complete the job of installing 2 window units in one day. It took him time to assess, install, clean up . I provided refreshments and beer after the job was done. I highly recommend Jason, on his ability to figure out what is needed by the customer. Aloha from a very satisfied customer. ð ¤"

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"Kyle, came to my house from kdr construction. I called him because I had some odd jobs around the house that needed to be done. He was very friendly, professional, and reasonably priced. He assured me that he and his company are basically a one size fits all. They can fix things, put in screens which is what I had done, fix holes in my wall, replace lights and the sky's the limit. Kyle worked quickly and efficiently and did a really nice professional job. I would highly recommend him for any future projects around your home or business"

FAQs for window a/c unit service or relocation projects in Kailua, HI

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
