We at Denoco can do anything from address your emergency heating issues; supply, install and service furnaces, heat pumps, radiant in- floor systems, hot water tanks, air conditioners; to plumbing new and existing homes. These services are just the tip of the iceberg in terms of what Denoco has to offer. To add to their offerings, Denoco is also the local dealer for everything Diakin!

Our tradesmen are certified in an array of specialties including 306A Plumbing, Gas Tech 2, 313A Refrigeration & Air Conditioning Systems Mechanics, and 308A Sheet Metal. But they are also able to guide customers through what can be an intimidating selection process, discussing the pros and cons of what is available – to help the client decide how best to heat or cool their home. It comes from a practical and financial point of view – from experts with answers.

    Denoco’s owner, Dennis O’Connor likes to think outside the box to provide the best possible service to his customers.
