Installation & replacement

Brown Chimney offers furnace installation and replacement in Ann Arbor, Michigan. A new furnace should be selected for your home's current heating demand, available energy supply and air-distribution system.

The size of the old unit is useful background information, but it is not enough to establish the right replacement capacity. Insulation upgrades, window changes and additions can all change what the home needs. Ductwork and airflow also need to suit the selected equipment.

For a fuel-burning furnace, the installation plan must account for venting. A replacement model may need a different arrangement from the old unit, particularly when switching equipment types. Those changes belong in the project scope before installation begins.

The Work

What needs to be planned before installation?

Heating capacity: A load calculation helps determine the output required for the home rather than selecting solely by square footage or matching the old unit.

Fuel and equipment compatibility: Confirm that the proposed furnace suits the available energy supply and the installation location. Fuel changes can introduce additional work.

Ductwork and airflow: Existing supply and return ducts should be evaluated for the selected system. Replacing the furnace alone does not resolve every airflow issue.

Venting and drainage: Requirements vary by appliance. Some high-efficiency furnaces need a different vent arrangement and condensate drainage, which must be reflected in the scope.

Plan your installation

When does a new furnace make sense to evaluate?

  • You are planning a full heating-system replacement.
  • You want to compare a new furnace with a heat pump or dual-fuel setup.
  • A renovation or addition changes the home's heating needs.
  • You are changing fuel type or moving the equipment.
  • You want to assess whether the existing system's capacity fits the home.

What to expect

What happens during furnace installation in Ann Arbor?

Furnace installation starts with the home's heating demand and the connections the new equipment needs. The five steps below cover assessment, the written scope, preparation, installation and startup checks, including venting where applicable.

01

Heating assessment & furnace sizing

Your home's heating demand, existing ducts, energy supply and venting arrangement are reviewed. Furnace capacity is based on the home's needs, rather than simply matching the size of the old unit.

02

Furnace selection & written quote

The selected furnace and installation scope are set out in writing. Equipment, duct transitions, venting changes and any required supply upgrades are identified, along with permit responsibilities, before work is approved.

03

Furnace removal & site preparation

The work area is protected and the installation location prepared. For replacements, the existing furnace is safely disconnected and removed as agreed, with retained connections assessed before the new equipment is fitted.

04

Furnace installation & connections

The new furnace is positioned and connected to the air-distribution system, energy supply and controls. Venting and condensate drainage are installed or adapted where required by the selected equipment.

05

Furnace testing & thermostat walkthrough

Startup checks cover heating operation, airflow and safety controls, with combustion and venting checks for fuel-burning equipment. You receive a walkthrough of the thermostat and operating instructions for your new furnace.

Moe (and team) did a great job with our chimney repairs! Moe’s inspection was thorough and he took the time to explain each task in the quote. Scheduling the repairs was easy and after the work was complete, he explained everything they did. Moe also took lots of pictures before and after the work to document, which I appreciated.

FAQs

Questions about furnace installation in Ann Arbor

1 icon

What size furnace does my Ann Arbor home need?

The appropriate size depends on the home's calculated heating load, including insulation, windows, air leakage and local winter conditions. Matching the old furnace or choosing solely by floor area can lead to an unsuitable size.
Faq Number

Can a new furnace use my existing ducts?

Possibly. Existing ducts need to be evaluated for condition, size and airflow compatibility with the proposed furnace. Necessary changes should be identified in the estimate.
3 icon

Will a replacement furnace use the same chimney or vent?

Not necessarily. Venting requirements depend on the new appliance and its installation instructions. A change to a different furnace type may require a new venting arrangement rather than reuse of the existing chimney connection.
4 icon

Should I choose a furnace or a heat pump?

The decision depends on heating demand, available energy sources, cooling needs and installation constraints. Compare complete proposals for the property, including supplemental heating where relevant, rather than equipment prices alone.
