Get Your Free System Design Consultation

Call or text (218) 525-5914, email kevin@designheat.net, or submit the contact form on this page. We respond to most inquiries within one business day and schedule a free in-home consultation to measure your home, review your existing system, and discuss options.

We design and install HVAC systems throughout Duluth, Hermantown, Proctor, Cloquet, Pike Lake, Esko, Carlton, Two Harbors, MN, and Superior, WI. We also serve the broader Northland and North Shore on a project basis. Our office is located in Duluth, MN.

Our free in-home estimate includes a walk-through of your existing system, a tape-measure heat-loss assessment (followed by a full ACCA Manual J calculation for any quoted project), discussion of equipment options and fuel types, and a written fixed-price quote. There is no charge, no obligation, and no high-pressure sales.

During winter months we make our best effort to respond to no-heat calls within 24 hours for existing customers. For new customers, we recommend calling our office first and we'll do everything we can to help or refer you to a trusted partner. We are not a 24/7 emergency-only service.

It helps to know the brand and approximate age of your existing equipment, the type of heat (forced air, hot water, electric), your home's approximate square footage, and any specific issues you're experiencing. Photos of the equipment label and mechanical room are also helpful but not required.
