What California neighbors say
Ricky walked me through the hows and the whys of the install of my humidifier prior to, during, and after. Install looks clean. After install he went through and explained the system (how it works, to use it, to check it). Post install there was no leftover debris or anything (to be honest looked better after the install than before). 10/10 would recommend. Great professionalism and cares about the work he does.
I couldn’t be happier with RE Graves. Responsive, reasonable, fair and everything else you want. Ricky also goes the extra mile…like installing a refurbished part temporarily until my new part could come in - allowing me to have heat when I otherwise wouldn’t. Customer service is top notch and then some!!!
