Recommended Customer Reviews

DNI heating & Cooling in Mead, CO. Came today and shut down 2 evaporative coolers. Their invoice charges for this service exceeded what I was led to expect. Upon setting the appointment the gentleman on the phone indicated I would get a discount for one cooler since I had two of them to shut down. After seeing the Invoice for the job there was no discount listed. The Tech then called the company and asked about it, but the discount was denied. I was also charged for a cover and shipping on the cover. Before install no one called to tell me the cost of the cover or that the shipping cost would be a third of the cost of the cover. I would have said no if they had. I called them back and requested a discount. They gave me the ""coupon"" discount which I didn't know existed until I went back into their website and saw it. However, I am disappointed with the company since I feel disadvantaged regarding the original invoice charges. There should never have been a charge for shipping, and it will remain in my mind and remind me to be more vigilant. Even through my disappointment I would still recommend this company on their service as the Technician did an excellent job. Also, in these trying times we are forced to live under, I would recommend DNI for acting immediately on my complaint and giving me the discount.

Chris Lucarelli, the tech, was earlier than we expected, did an amazing job, at a very reasonable price. I would recommend DVI to anyone needing HVAC service! 5 stars for sure!

Mike was great. Quick. Friendly. Knew his business. DNI seems to know mobile homes the best. Recommend!

Total rip-off! Unskilled technician misdiagnosed problem and replaced unbroken parts. When asked to put back the original part, he wouldn't then kept my old perfectly fine part. Said something else was wrong and said would order that part. A month later, no part, no call, no returns on call. Just keep getting bills. Charged close to $1000 for service call and repairing ""nothing."" Called three times and the owner did NOT return my call. Terrible communication skills and lacks professionalism. Just want your money for doing absolutely nothing. My appliance is still in the original broken state but with $1000 less money in my pocket. I paid like a good person would although I know I'm not obligated to pay for the ""nothing,"" but figured these people are snakes and would most likely keep adding late fees etc and send creditors after me to ruin my 815 credit score. Totally not worth it. I'll just let karma bite them back. Shame on you!!!!

They were professional, friendly, and careful not to damage anything in my apartment.

This is really nice. Thanks for sharing.

They came on time, were prepared, professional, and fair.
I was told by a different HVAC company that both my furnaces needed to be replaced, but DNI told me that was untrue. They saved me around $20k and I will never use anyone else again.

I needed my compressor replaced in my three door cooler. After one of the service guys came by to check out the job, he quoted me $1100 over the phone to replace the compressor. He did a good job, everything worked. When he wrote the bill, he added another $95.00 for a ""diagnostic"" fee. I'm a firm believer in doing what you say. If you say $1100, that's what i'll pay. The service guy and his partner were very, very rude to me and told me not to call them again because I didn't pay the extra charge. Beware of this company. They are not honest people. They also decided not to warranty the compressor and work they did. The warranty was supposed to be for a year :(

Woke up the other day to find we had no hot water running. I figured the pilot light went out on our boiler and wasn't sure how to light it. I called DNI and they were able to send someone out the same day and within a window I could live with. They arrived found that it was a defective part and did a complete review of the boiler. They got in and out and left me very happy. Great folks there.
