So they came to my house for the annual cleaning and also to fix my AC. I was told the amount would be 250.00!!!! The guy came upstairs with a bill for 451.13!!!!!! I nearly fell to the floor. They were here for 1.5 hours but left and my AC isn't even working!!!! Unbelievable!!! I will have them come back only this time to finish the job but I would definitely not recommend this company at all!!!!! Ripoff city So they just came back to fix the leak in my system which they found in less than 5 minutes. They were here maybe 1 hr if that. He came up with a bill for 424!!!! Labor costs for 190.00!!!!!!! Are you kidding me????? Don't hire these people !!!!!!! read more

***DO NOT HIRE THIS COMPANY!!!*** These guys are complete scam artists. After 3 visits and $500+ later, they never fixed our heating issue! If that wasn't enough, the owner of DDM Heating (pictured next to the work van on this Yelp ad), actually called us back & told us to take them off our contact list and to never call them again. What a complete scum bag!!! Don't waste your time or money on these guys! I honestly think DDM stands for Dooshbags, Dummies & Morons!! read more

This place is only out to rip you off folks. Do not hire these people. They are thieves!!!!! They charge you the labor of 2 people when the job requires only 1. Their prices are not consistent at all. The owners charge whatever they want. My 2 bills were 800 and they did absolutely nothing!!!! Their guys sat in their trucks for 90% of the time. Be very careful... they are shysters!!! Awful awful awful!!!!! Rip off city!!!!! Don't hire these folks people!!!!!! Mary and Dan are shysters!!!!! I don't know how they've been in business for 25 years cuz they are the scum of the earth!!! read more

We have had DDM heating service our boiler for the past two years. Recently we have had some issues with hot water, and they have been awesome. We had Jesse come out to look at it, explain our options, and fix it. Both times he was polite, efficient, and fixed the problem. He came this week during the COVID-19 quarantine, and when he did have to come up into the house he called to us, wore his mask, and gave appropriate social distance. This company has honest hard working people- I know we will get great work and a fair price whenever we call them. read more

Mary unprofessional and Dan's service skills are suspect at best. (1) The time DDM serviced air conditioner, it take about 2 hours for the Service person to identify a bad capacitor on the compressor motor, after the part was replaced, the started to work but wasn't blowing cool air so I asked the service tech to check Freon and charge the if needed, he replied I'll have to ask Dan, you probably guess already that Dan said "No" for him to end the service call and for me to call and schedule another service (more $ and another day off from work for me). read more

The oil service that we use on the house recommended a repair service when the boiler was acting erratically. After calling DDM the receptionist couldn't be less interested in helping anyone. And, funny my experience wasn't solitary based on the other reviews. When I asked them to help with our boiler, we don't do any work for anyone related to the company that had recommended them. Well, if you don't want to be in business, then don't be. And for cripes sake get that receptionist off the phone, your business already is a 1.5 star. You can't get much lower, but, keep trying for a zero. Please make sure that don't use DDM -- I would think all the 1 stars would give you all the information you need. read more

Jesse arrived on time, and installed my new vanity, repiping was needed as my vanity had drawers, so pipes needed to be relocated within the wall. All went smoothly for a 100 year old home. I think the job was completed professionally and within reasonable time. Jesse was great, very knowledgeable and I was comfortably having him work in my home. Jesse explained everything he did when he was finished, including showing me where under the unit I could find the water shut off. I am thrilled with the results and would not think twice before calling DDM again. Elizabeth in Hudson read more

My experience with DDM Heating and Air has been extremely unpleasant and left me with a large invoice that I never gave authorization for. I called DDM in the middle of July to check on a noise my AC unit was making at my rental unit. As this is a rental unit, my tenant was present for this service appt. I was called by Dan at DDM and was informed that the noise was simply a piece of plastic on top. He did however suggest I have the unit cleaned because it was very "gross". At this point my unit was working fine. Then a week later, the fan stopped working and the unit was no longer producing cold air. I called DDM and they went to the unit and apparently fixed it. I was not called and made aware of the fix or any issues that were found with the unit. The unit worked for another week then the fan stopped working again. Again I called DDM to check on the unit. At this call, Dan informed me that at his previous visit, he discovered the switch was broken and that he simply "jammed it into place". He suggested that the switch was turned off. At this time, I asked if this is something I could fix and he said "well yeah. You could jam it up with a screwdriver but then you'd be dealing with the electricity." My father is an electrician so I know the dangers of electricity. So I told Dan to go look at it. He said he would send a technician to check it out and change the switch box. I received an invoice last week for $500 for 3 hours of labor, a new switch and new motor. I was NEVER called and asked if I wanted to have this repair done. If I had been, we would probably have had the whole unit replaced. All I expected was a phone call for authorization of additional work. When I called DDM this morning he said that it isn't there policy to get approval for these types of services. I pointed out that he called me a month earlier to up sell me for additional service on a completely functioning unit. Dan tried to tell me he did me a favor because my tenants would withhold rent if he hadn't fixed the unit so fast. My tenants made a point of saying to me that they hoped I wasn't getting charged much because no real work had been done. During this call he laughed at my numerous times and spoke over me. When I informed him, that while I will pay my bill in full, I would be contacting the Better Business Bureau and review DDM on Yelp. He said to "go ahead because those things are jokes." The one thing that was very pleasant was that I received a call from the owner Mary apologizing for any confusion. She has been a pleasure to deal with at DDM. read more

I am not sure how their technicians are, but their office staff has quite a bit to learn on how to be courteous and professional. Their receptionist very rudely told me first to hold, where I did hold for 20 min and called back she said I told you to hold and she hung up on me. Not impressed and not a great first impression. Will not be using this company in the future. read more
