Furnace Replacement & Installation in Washington Township, MI

Decide from the findings, not the furnace's age alone

Compare safety, the diagnosis, repair cost, overall equipment condition, parts availability, efficiency, airflow, comfort, and how long you expect to own the home. Ask which problems a repair would solve and which would remain after a replacement.

If the immediate issue is no heat, ignition trouble or repeated shutdowns, start with furnace repair in Washington Township. That page also explains the urgent steps for gas odor or a carbon monoxide alarm; do not wait for a replacement estimate in an emergency.

What to review in the installation scope

A useful proposal explains the equipment and the work around it. Review these items with the contractor before authorizing an installation:

1. Home and equipment assessment: heating requirements, existing equipment, insulation, access and the comfort concerns you want addressed.
2. Ductwork and airflow: supply and return restrictions, filter access, transitions and any changes included in the proposal.
3. Venting and connections: the selected model's combustion-air, venting, gas or electrical, and condensate requirements, plus applicable permit and inspection responsibilities.
4. Startup and commissioning: the equipment-specific checks and recorded results, including applicable airflow, temperature-rise, combustion, control and safety checks.
5. Handover: thermostat operation, filter guidance, equipment documents, warranty terms and registration responsibilities.

The Department of Energy's furnace installation guidance explains why equipment sizing and the distribution system affect performance.

Compare AirEase and Ducane by the proposed model

AirEase and Ducane are among the furnace brands Cooley Mechanical discusses with homeowners. Compare the proposed model's heating stages, blower type, efficiency rating, thermostat requirements, service access and documented warranty terms against your home and priorities.

Features vary within each brand. A brand name alone does not establish that a furnace is modulating, has a variable-speed blower, qualifies for an incentive or is the right match for existing components. Use the current AirEase furnace information and Ducane furnace information to review the exact equipment under consideration.

For an electric heating system, review our electric-furnace diagnosis, repair and installation services. Fuel availability, electrical capacity, the existing system and the proposed work need their own assessment.

Compare the written scope and total installed price

Ask the proposal to identify the exact model, included installation work, any duct or venting changes, controls, removal of old equipment, permit responsibilities and exclusions. Confirm timing and any follow-up commitments in writing. Do not assume a fixed installation duration or a diagnostic-fee credit.

For the broader questions to ask, see our HVAC replacement cost guide. Financing information is a separate part of the decision; confirm current provider terms and eligibility before applying.

The federal Section 25C furnace tax credit no longer applies to equipment placed in service after December 31, 2025. Some Michigan utility rebates may still be available, but eligibility depends on the customer’s utility, the exact equipment and efficiency rating, the property, contractor participation, installation timing and remaining program funds. Any incentive should be verified for the specific home and model before it appears in a proposal.

See the IRS credit information for the federal program's dates. Ask for the exact model and current program documentation before including any proposed incentive in your budget.

Furnace replacement questions

Can the existing ductwork stay?

That depends on its condition and suitability for the proposed equipment. Have the contractor explain any airflow or duct changes included in the scope; a new furnace alone does not resolve every comfort problem.

Will I need different venting or a new thermostat?

The answer depends on the selected model and existing installation. Confirm venting, drainage, wiring and control compatibility before comparing final quotes.

How long will the work take?

Ask for the expected schedule after the site assessment. Access, equipment availability, duct or venting work and inspection requirements can affect timing.

What should I receive after installation?

Ask for equipment identification, operating instructions, relevant startup findings, warranty documentation and clear registration and maintenance responsibilities. Keep these records together for future service visits.
