What People Are Saying

Real customer experiences from your community.

Kaleigh
Steve is an amazing salesman. Absolutely 10/10 if you are in the market Steve is your guy! Made sure we got the best bang for our buck. Made everything so easy. Can’t wait to deal with him for heat pumps in a few months. Norm installed and as you can see, it’s so clean and neat. Made sure we actually understood our system and how to make it work best for our home! Cannot thank them enough. We are so pleased!
Graham
Excellent response time for my emergency furnace repair. No run around, fast call back after hours and spoke with the repair person within minutes. He had the part replaced and furnace back on within 20 minutes of arrival. Exceeded my expectations in every way!! Definitely recommend.
Anthony
Overall experience was excellent Steve was very thorough during the initial walk through. Appointment was booked and the guys showed up as scheduled. Norm and Nick did a great job on the install. Norm was very informative on the heat pump being installed and presentation looks excellent. Happy with the service, keep up the good work fellas.

Prompt service, quality and quiet appliances,respectful serviceman about cleanliness also take time to explain asked questions. Also very friendly staff makes you fell at ease. Best of all sales will let you decide after properly thinking about your purchase. Not pushy people.

Awesome experience with DNM for duct cleaning done at my home. It was a pretty clean, quiet and pleasant experience for those 2-3 hrs spent doing the duct cleaning and getting my questions answered was much easier. Super friendly people and I do recommend using DNM for your next duct cleaning. 10/10.
Bill
We purchased a napoleon bbq from them just before Christmas. Quote and responses on email were answered very quickly. Had unit assembled and it arrived last day before Christmas. Even though the office closed early, service told me they would stay until our son got off work with his truck to pick up. Staff was extremely friendly. Would definitely recommend DNM!!
