Best in Oklahoma City OK

Wired some lights for the eves of the house and some ground flood lights. Lights look great and work as advertised. Installation was very professional and cost was not inflated. Will definitely use again if I have any electrical needs.

I would not recommend this company.  Although the guys were polite and upon my request, removed their shoes to go thru the house and cleaned up afterward (including taking the box and manual for the item that I purchased myself and had them install, hopefully I won't have to return it for the warranty), they were over 20 minutes late, installed an item without discussing it (a new outdoor receptacle cover upon replacing the receptacle), charged a $12 trip charge that when I received the quote was told was around $10 if over 20 miles (upon bringing to his attention that Gai said only if 20 miles or more & I am under  that, Rodney removed the charge), in addition to charging for the materials they used, they charged a misc materials fee of $6, so by my estimations, a charge of 15 minutes travel time that I was not informed of during the estimate inquiry ($196.88 total charge for 1hr for two guys to run wire in the attic for the floodlight @$157.50/hr and 15 minutes drive time @ $39.38) $157.50 x .25/hr drive time = $39.38 + trip charge $12 + outdoor receptacle cover installed without my permission $17.65 + misc material fee $6 = $75.03 less the removed $12 trip fee = $63.03 overcharge.  I would've given 3 stars as the work was okay, however when I called to inquire why I wasn't told the time started when they were on their way, in addition to the trip charge, & other charges (mentioned above as overcharges), Gai said she was the Office Manager and I could talk to her; however part way thru, she interrupted me, became loud, sarcastic &  defensive, said they have a 5 star Google rating with no complaints (which they do have complaints, albeit they are few, which is one reason I chose them); I remained so quiet thru it all, that she asked me several times if I was still there, to which I answered Yes and later, I'm still here, I was just letting you finish.  She then calmed down so I went on to say One of the points I was trying to make, is that you should inform people the time begins with the drive time as this was my first experience with an electrician, so I wasn't aware of that and I'm sure there are others who aren't aware, and when I first questioned the charge, you verified the trip fee and that the time starts with driving to the job location & not upon arrival. Then later in the conversation, when I mentioned it again and that Rodney had removed the $12 trip fee, you said you don't know what all they charge.  Additionally, an electrical outlet receptacle cover was installed without asking me first.  She then said the cover should not have been installed without talking to me, that she would review the bill when the guys returned with it that evening, issue me a credit although, since the credit card had already been charged, she didn't know how to issue the credit and would have to find out and call me back the next day; that was Thursday, today is Tuesday and I've yet to get that return call or credit, so they don't keep their word and their honesty is questionable at best.  As the Office Manager, she should be aware of basic charge such as the amount of the $12 trip fee and that it is always charged in addition to the always charge of $6 misc materials fee and - how to issue a credit back to the credit card!!  Thru it all, at no time was an apology given for her outburst, the lack of information/clarity or any misinformation given, the part installed without permission, or the tardiness of the workmen.  One last note - Gai stated that the guys hurried for me and did it in less time than it normally takes however, when she initially scheduled the appointment for 8:30 the next morning, they only had an hour between my appointment and their next one at 9:30, so...

I had Harrison-Duncan come out to perform some electrical work at my house pursuant to my home warranty.  They called to schedule my appointment within a day of me making the claim with my home warranty company.  They had availability only a day later, so that was appreciated.  

I was quoted a time of 8:30 for the arrival of the electricians, and my doorbell rang at 8:28.  2 gentlemen went to work and within minutes had diagnosed and resolved the problem.  They were out of my house by 9:00.  They were prompt, courteous, and friendly.  No complaints in that department.

The reason I am giving 4 stars instead of 5 is that they did not clean up their mess.  In fact, they didn't offer to clean it.  It wasn't a large mess, but the fact that they didn't offer was annoying to me.  But, I am sure this was an oversight.  I'd recommend Harrison-Duncan and would use them again.

I used McKenna to install a new furnace and condensor unit installed in June 2016. Everything was fine until this past month when I went to fire up furnace and wouldn't turn on. Called McKenna who sent tech out who spent 10 minutes to discover a small hose was rubbing against a pressure switch which he simply moved. I was charged a $79 fee because it was out of warranty which granted it was by 4 months but it is also a brand new system I spent over 7k on and this type of fault shouldn't be occurring. After speaking with the office manager she said they would review my case and call me back with a decision. Today the fee was processed with no call and I am disappointed because it seems to be more about the money than common sense or good customer service.

Can't say anything good about this company!
I called and left messages several times and no one ever returned my calls or  left me a message! I would say if that's the way they handle their answering service part of their business; I don't want any part of the rest of their company.
