Hiatt Service LLC operates as a dedicated HVAC contractor serving Ottawa, Kansas and surrounding communities with a perfect 5.0-star rating drawn from 131 verified client reviews. The company maintains standard weekday operations Monday through Friday from 7:30 AM to 5:30 PM, providing service calls and new system installations throughout the greater Ottawa metropolitan area. Reviewers consistently reference the team when discussing their experiences, noting professional interactions with crew members including technicians named Cole and Austin. The business handles residential heating and cooling projects ranging from routine maintenance to complete system replacements.
What distinguishes this contractor from area competitors stems directly from reviewer accounts describing project scope and problem-solving capability. Clients note the team's ability to source difficult-to-find replacement parts within one business day, resolving furnace issues that previous contractors declared unsolvable without full system replacement. The technicians demonstrate versatility across multiple equipment types including forced air gas systems, ducted mini-split configurations, and various ventilation components serving bathrooms, kitchens, and laundry areas. Reviewers repeatedly praise the crew's clean working practices and efficient project completion timelines.
Customer narratives provide the most detailed picture of actual service delivery. Barb Griffin's review describes a scenario where competing companies demanded $5,400 for a new furnace claiming unavailable parts, yet Hiatt Service located the necessary component the same day the owner was contacted and completed the repair by the following day. Multiple reviewers mention specific technicians by name, with Austin receiving particular commendation for taking time to thoroughly explain system operation and answering technical questions. Jill Packer specifically notes the team's thorough cleanup following a new system installation, mentioning the crew removed all packaging materials and debris.

Four reviewers describe same-day or next-day response capabilities, with one reviewer contrasting this against competitors who claimed parts were unavailable.
