Furnace replacement in Ottawa, KS

Focus on the installation details behind the equipment label.

Separate diagnosis from a replacement proposal

Ask what failed, whether repair is practical, and which concerns a replacement would solve. We cannot evaluate a furnace remotely. Arrange any equipment or combustion-safety assessment with an appropriately qualified professional.

What a furnace proposal should explain

Equipment model, fuel type, efficiency rating, and proposed capacity.
How the contractor evaluated the heating load.
Whether existing venting, combustion air, gas or electrical connections need work.
Any changes to duct transitions, thermostat, filtration, or condensate handling.
The labor warranty and responsibility for future service.

If you are keeping the existing air conditioner

Ask the installer to document compatibility with the proposed furnace and indoor coil. Request an explanation of what is being reused, what is being replaced, and what that means for the warranty.

Bring the same questions to each appointment

A lower price may reflect a different model or a different scope. Use our comparison worksheet to reveal those differences before deciding.

Make the handover part of your plan

Ask for equipment model and serial numbers, startup records, operating instructions and warranty registration responsibilities. Clarify who handles follow-up questions and whether a later adjustment visit is included. Keep the final invoice and the original scope together.

Questions to settle before installation

Who handles permits and inspections?

Put that responsibility in the written agreement and confirm the applicable authority using your property address. A mailing ZIP code does not determine every jurisdiction.

How do I compare two installation proposals?

Line up exact equipment models, work included, exclusions, permit responsibilities, warranties and total installed prices. Ask about differences before treating the lower total as the better value.
