Our Transition from Carrier to Day & Night: Commitment to Quality and Value

Our journey began in 1986 when Larry Ernst, a small-town Iowa farm boy, founded Intermountain Heating & Air Conditioning Inc. Larry's dedication to quality led us to become the first Carrier Factory Authorized Dealer in Idaho. Despite this strong start with Carrier, we decided to move away from Carrier in favor of Day & Night to better meet our customers' evolving needs for cost-effective, reliable HVAC solutions. For over 33 years, Larry dedicated himself to serving the Magic Valley and surrounding areas with a remarkable work ethic, a love of people, and a giant heart, becoming widely known among his customers and the community.

In 2024, fter careful consideration and thorough evaluation, we decided to transition from Carrier to Day & Night. This decision was driven by our unwavering dedication to providing our customers with the best possible value without compromising on quality. Day & Night emerged as the optimal choice due to its comparable quality to Carrier at a more competitive price. While our company's heritage is deeply tied to Carrier, we recognized our customers' evolving needs and preferences, who increasingly sought cost-effective solutions without sacrificing performance or reliability.

By embracing Day & Night, we can continue to uphold our standards of excellence while offering our customers enhanced value and affordability. This transition reflects our ongoing commitment to adaptability, innovation, and customer-centricity, ensuring that we remain at the forefront of the HVAC industry while consistently exceeding the expectations of our clientele.

Our decision to switch from Carrier to Day & Night in 2024 was driven by our dedication to providing our customers unparalleled value, quality, and service. We are confident that this transition will further strengthen our position as a trusted leader in the HVAC industry, and we look forward to continuing to serve our customers with excellence and integrity.

 

New beginnings

We lost our beloved founder in August 2019. We miss his infectious laugh and spontaneous sense of humor. Larry’s spirit will forever live amongst the employees of Intermountain Heating & Air. Before passing away, Larry asked his long-time friend and general manager Kosta to take over the company.

In April of 2020, Intermountain Heating & Air Conditioning was purchased by Kosta and his family. As a family and veteran-owned business, we aim to continue based on the principles Larry championed while working to make it easier for our customers to connect with us online.

Kosta came from a communist country with $42 in his pocket and three words of English in his vocabulary. What Kosta did have, was an eager spirit and a hard-working attitude. That attitude resulted in Kosta becoming a lifer at IMHVAC, eventually purchasing it after Larry’s passing. Kosta wanted to see Larry’s dream live on. So to this day, we hold onto Larry’s vision, rooting for the underdog, creating amazing employee and customer experiences, and constantly on the lookout for new ways to grow. 

That’s why, for the first time ever in the company’s history, we are taking massive steps to increase the benefits offered to our employees, including extremely competitive wages, full health and dental insurance, and even tuition reimbursement. We support those who support us. And right now is the best time to join if you want to be a part of the growth and set yourself up for a future position in leadership. 

Our Team

  • General Manager/Owner

    Kosta

    General Manager/Owner

    Our fearless leader and Larry's long-time friend and general manager. Boy, do we have Kosta and Larry stories. Those two were quite a team together. Larry knew that Kosta had the knowledge and experience to diagnose and repair any job. Kosta's experience in the industry and relationship with Larry made him the perfect candidate to continue his legacy at Intermountain Heating & Air Conditioning.

  • Carl

    Service Technician

    Carl is our part time service guy with all the knowledge. He has been in the industry over 30 years and has all the knowledge. He is usually out on the job most of the time but we sure love love his spunky personality and jokes when he is at the office.

  • Brody

    More information coming.

  • Teresa

    Office Manager

    Our trusted office manager started as a seasonal, part-time employee and quickly became an incredible part of our family. Larry hired Teresa full-time after a couple of months, and we could not be happier for that decision. We value her time, dedication, and knowledge and are thankful she chose to stay on full time. She is the friendly voice behind he phone and will quickly become your friend.

  • Silvanna

    Marketing

    Kosta asked his daughter Silvanna and son-in-law, John, to purchase Intermountain Heating & Air conditioning. He knew that while he had experience in HVAC, he needed 'young blood,' as he put it, to help him navigate change management and technological advantages.

    Silvanna is our marketing / social medial professional. While her experience lies largely in social media and Industrial/Organizational Psychology, she enjoys her new role in marketing.

  • John

    Owner/ Advisor

    John is our 'behind the scenes advisor.' He is a retired United States Air Force veteran. After spending 20 years in the US Air Force, John began working for a tech company remotely and joined the ranks of IMH as part owner. He is the behind-the-scenes team member, a valuable advisor, problem solver, and an overall 'ideas guy.' He is Kosta's son-in-law and Silvanna's husband.
