Best Businesses in Oklahoma

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.

First time to use Aspen.  Electricians were professional and their work was top notch.

I have scheduled some more work with them next week.

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.
