It’s been in the upper 90s for most of the last week and I’ve been trying to nurse this air conditioning through it and finally gave up and read and found good reviews for D & M and gave them a call on a Friday afternoon. And was not expecting anything to come anytime soon being it’s been a long week. I’m sure for these gentlemen but lo and behold. She said he might be able to come help me after his last call. And he did Dan came out and troubleshot it and got it going better than it has been and didn’t try to hard sell me on a whole new unit or any such thing in fact recommended trying to nurse it along for now And I can’t say I appreciate that enough because been a tough year and will be better next year and can really appreciate the hometown feel and a business that’s in it for the long haul and wants to be Who you call when you need help in the future. So thanks, Dan and I can’t remember the other half on the phone’s name but they were both wonderful and I can really say you’ll be getting a call from me anytime I need anything else you guys were great. Can’t recommend you enough and thanks again.

It’s been 97° most of the week and I’ve been trying to nurse this air conditioning unit and gave up and called D&M. Around 3 o’clock today this afternoon and he finished up what he was doing and came out here after working on extremely long week. I’m sure And got me running back in able to keep cool. I have nothing but great experience from the phone call talking to the receptionist who happens to be an owner and the other part of the owner came out and did the work and talk to him about the future that I’m gonna need a new furnace and air-conditioning unit and he said instead of trying to push and hard Cell me into getting one said milk this as long as you can And I can appreciate and respect the lack of a hard cell and understanding from another Demont homeowner and business owner that if we can wait till next year, it would be much better. Very very knowledgeable and I had a lot of questions for him and he had answers for all of them. Can’t say enough good about this company. Will absolutely use them again. Highly recommend.
