    COOL GUYS MECHANICAL Business Card!
    Donovan H.

    Well, We Had A Situation. Our Original HVAC Contractor Here On The Big Island Was Unable To Fulfill Our HVAC Contract Due To Unforeseen Circumstances. I Had A Close Friend Recommend (John Bonilla) at "COOL GUYS MECHANICAL" On Oahu. We Talked and Texted For A Bit And Was So Fortunate To Have John Match Our Original Contracted HVAC Quote With The Same Fujitsu 45k BTU Central HVAC System, Plus Fly To The Big Island (Waimea) To Get This Job Done In An Efficient And Timely Manner. "COOL GUYS MECHANICAL" Comes HIGHLY RECOMMENDED. It Should Be Known That He And His Technicians Take PRIDE In What They Do, As If They Have The Same OCD As Me And Are True 'Perfectionists' At Their Trade!!! *See My Photos For This Awesome HVAC Install.

    Just gorgeous!

    This is for call back due to defective double kitchen sink…read more Plumber Korey was on it and he was assigned the job and did great job and due to my earlier frustration with slow office support (they should just say they are understaffed and slow) that he would follow-up with me. They are on the higher $ide but are worth it. I joined Ohana Club for just in case.

    Plumbing repair by Steves plumbing. Water is leaking from my…read moreshower so i contacted steves plumbing and they showed up promptly, while checking the fixture the tech checked the water pressure which was over 200 psi. He said i need to change the prv valve before any repairs could be done as the water pressure should be around 60psi. I have changed the prv in the past, about 4/5 years ago so i told him to go ahead and change it as im pressed for time havjng to work and prepare for the incoming typhoon. He didnt have a valve so needed to go to city mill to get one which they had in stock. The total repair came out to $4100, of which and i'll break it down cost wise. Costs gotten at a consumer pricing from Home Depot Now mind you this is the retail pricing for an normal consumer, not professional pricing (what you or i would pay if going into the store) Prv valve $89 5' length 3/4" copper pipe $50 Fittings $50 Ball valve shut off $ 19 Total of parts $208 $4100 minus the parts needed $208 $3892 labor 18 minutes to complete the repair, say 30 to make it easy $7784 in labor charge per hour I guess i should have purchased a solderless crimper and done it myself for a savings of $3900 Work was done professionally and quickly as promised and the area cleaned up before completion but the labor cost is whats bugging me- guess i got into the wrong profession

    The KK Air conditioning team was fast to respond, professional, reliable and a high-quality AC…read moreservicing team. Myra (office manager) was very sweet and got back to my quote and questions very fast, explained to me whats was included with maintenence cleaning my split AC indoor and outdoor units and was able schedule maintenance with my day time preference in 2 days. They partner with Hawaii Energy and gave me $150 off instant rebate for maintenance cleaning both my indoor and outdoor units, which made their rate very competitive compared to all the other company quotes. Cleaning day I was notified in advance when the technicians were on their way. The 2 technicians were professional and came on time with their company KK air conditioning truck and van. They were both very nice and patient with my 2 curious toddlers and dogs. The cleaning work was phenomenal, and both indoor and outdoor units were squeaky clean when they were done. 3.5% fee for credit card payment and received an email invoice receipt. Im very grateful to the KK air conditioning team and will definitely be calling them again. Thank you KK Air Conditioning!

    In mid May 2024, I had our central air conditioning serviced. I contacted this company after…read morereading the reviews. The appointment was made very promptly and Myra was very friendly. On the day of the appointment, we noticed the two technicians were consulting with someone on the phone. We found out later it was the owner of the company. Long story short, they were confused about the drain lines and had to spend additional time "unclogging " them ( which we were charged for). We paid over $500 for this "service"! We were grateful for what we thought at the time was their due diligence and thoroughness. I even wrote a very complimentary review on their website. Fast forward to August 31, 2024 when we discovered a leak originating from the upstairs ceiling. The origin of the leak was an overflow of the drain pan from the air conditioning unit because the drain was not working properly! I immediately called KK air conditioning to let them know and Keith the owner came out. He informed us that the installation of the condensate pan was improperly installed (this is not true because this is not a new installation and we have had it assessed by two other AC companies since then and they did not mention improper installation) which caused the leak and that the technicians cleaned out the secondary drain because the primary drain was difficult to access as it was underground?!? I asked him why weren't we told this at the time since we're not the air conditioning experts and he replied, "they're just technicians " . Keith felt he was doing us a BIG favor by not charging us a fee for coming out to check on this problem. The cost for the damages of the leak was over $53 thousand dollars and took 3 months to resolve. Our homeowners insurance was increased 278 percent for 5 years!
