About Us

Trademark Heating & Cooling is your premier HVAC company, serving homes and businesses in North Idaho and Eastern Washington for over 17 years. Company owners Tony and Gwen Marmon take pride in quality craftsmanship and friendly customer service. We bring a wealth of experience with professionalism and courtesy to every project—we deliver on our promises! With prompt, efficient heating and cooling services, we have built relationships with customers, vendors, subcontractors, and our employees, who we are proud to call our partners.

Trademark Heating & Cooling was created in 2004. We operated it from Tony’s home garage, with a few tools, a second or thirdhand pipe threader, and a little green truck nicknamed “Old Greenie.” Many evenings and weekends were spent cruising the streets of new developments, searching for signs, or perusing the permits section of the local paper to obtain contact info and convince the builder or homeowner to use Trademark Heating & Cooling to do their HVAC work.

From this humble beginning, we built upon a foundation of quality, customer service, and relationships.

Tony has been in the HVAC trade since he was 18. He attended trade schools and continues to improve his toolbox of skills by studying a broad range of books, attending conferences, taking educational courses, utilizing mentors, and generally being a student of life. Born and raised in North Idaho, Tony and Gwen jealously guard Trademark's reputation for integrity and quality. We hold ourselves personally accountable to our Trademark Team, community, and customers who live, work, and play in the same beautiful area we do.

We have come a long way from our beginnings. When we started, we offered only residential new construction. We now offer many services, including commercial and residential installation and service. From zero employees, we are now honored and blessed to provide jobs to more than 100 people. They are teammates, partners, friends, and family. From working out of the family garage, we are proud to say today we have locations in Hayden and Sagle, Idaho, and Spokane, Washington.

Oh, in case you were wondering, “Old Greenie” still runs like a champ alongside a whole stable of newer, decal-wrapped siblings. Trademark strives for growth and excellence.

Our motto, “Excellence Is Our Trademark,” is our battle cry. Our team takes great pride in providing exceptional customer service. We have fun looking for ways to “WOW!” our customers. Our willingness to always do the right thing, along with a determination to grow as individuals and as a team, make us the company of choice for all heating and air conditioning needs in the markets we serve.

Our mission is to continuously improve and grow our character, relationships, and skills while providing excellence in service to our customers and community.
