Jim is always very helpful & professional. We have had him convert our oil furnace to gas, install central air & put in a new water heater. D&D is awesome and we have more jobs lined up for them!

Jennifer Dvorak

Chose D & D to replace 26 year old furnace and AC as the heating season began after getting bids from other companies and upon advice from a friend who has had D & D do installs at multiple family homes. The entire transaction from original bid to installation was done within the same week the bid was accepted. D & D produced excellent workmanship with the install & modified ductwork as well as fixing a previous cobbled done by another company. I will continue to use D & D for future HVAC seasonal checkups as they have earned my business with their friendly professional service! It’s great feeling to have peace of mind that my HVAC needs are taken care of by D & D.


Great Guys. If you need any sort of help with your air conditioning or heating don’t even bother calling other HVAC companies. I got bids from 5 of the top HVAC companies in Dane county and D&D came through with a bid lower than the rest. The attention to detail and professional personalities will make me a return customer and pass their name to everyone I know. Save yourself the time and call D&D.-
