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.

If you’re looking for a company to come service, your furnace or air conditioner, they will not take advantage of you will tell you the truth give you the best advice and be sure that your satisfied and back up their service and installation then look no further than D&M. Dan and Jon have both been up to look at the furnace and air-conditioning in our top notch, very knowledgeable and straight shooters. I know for the average person we don’t know a heck of a lot about furnaces or air-conditioning, but they’re very explanatory and informative as to what they need to do and why they’re doing it. I can’t say enough good about them both. Highly highly highly recommend you’ll be very satisfied. Testimonial written by Bob Hughes on this site.

I am so impressed with this company. In a world where good service at a decent price has gone out the window, D&M let you know there are still GOOD and HONEST repair services. From the moment I called to schedule someone to come out, you felt like you mattered. Dan arrived on time and got right to work and within an hour had my issue solved. I've already asked to be put on the list to have regular spring and fall maintenance done to head off problems... but I will 1000% recommend D&M to anyone that asks for a recommendation for HVAC folks! D&M keep doing what you do so very well!

Was so impressed with this company - from the phone call to set up the service to the actual appointment - this company truly is top notch. They don't fix things that aren't broken. Sometimes you leave a repair place or have a repair done and you just feel like you've been taken advantage of, never once time did I feel this with D&M - I will always recommend them to anyone asking for HVAC company!
