About Monaghan

Trusted local HVAC experts since 2004.

It started with a 12-year-old sweeping floors at a Hayden HVAC shop. Kevin Monaghan found his calling in sheet metal, and in 2004 struck out on his own — building Monaghan Mechanical on integrity and craftsmanship.

From custom homes to light commercial and kitchen systems, Kevin and his crew deliver personalized heating and cooling solutions tailored to North Idaho. Honest communication, reliable service, and treating every customer like family — that’s the difference you can feel.

“The greatest reward our customers can give us is the referral of a friend or family member. Thank you for your trust.”
