Heating and cooling due diligence for Michigan IRA property

A furnace can start during a showing and still have an uncertain repair history, a damaged vent, or a distribution problem in the farthest room. An air conditioner can produce cool air without showing how it performs on a hot afternoon. Heating and cooling due diligence needs more than a quick thermostat test. The equipment, fuel, venting, ducts or piping, controls, drainage, records, and proposed use all belong in the same review.

For a self-directed IRA buyer, the operating plan matters just as much as the inspection. Service calls, replacement work, utility changes, permits, and emergency repairs need a clear payment path through the account. The plan should not depend on the IRA owner doing mechanical work, buying a furnace personally, or paying a contractor while waiting for the custodian to reimburse the expense.

Build the equipment record before testing the thermostat

Ask for installation invoices, permits, final inspection records, service reports, warranty documents, fuel-conversion records, equipment schedules, and manuals. Match each record to the equipment in the building. A receipt for an outdoor condenser does not establish the age or condition of the indoor coil, furnace, air handler, controls, refrigerant lines, or ductwork connected to it.

Record model and serial numbers when they can be read safely, but do not turn an online age estimate into a condition report. Equipment can be replaced in pieces. Labels can be missing or difficult to interpret. Prior maintenance, installation quality, sizing, operating hours, water exposure, and the condition of connected components all affect the review. Ask a qualified mechanical contractor to identify what is present and explain the limits of any age or remaining-service estimate.

• Every furnace, boiler, heat pump, air conditioner, mini-split, air handler, unit heater, rooftop unit, fireplace, and supplemental heater
• Fuel type, utility or storage arrangement, shutoffs, meters, tanks, regulators, chimneys, vents, and combustion-air provisions
• Thermostats, zone controls, pumps, humidifiers, dehumidifiers, condensate drains, filters, and other accessories
• Ducts, registers, returns, hydronic piping, radiators, baseboards, and equipment serving detached or mixed-use areas
• Permits, final approvals, service history, warranty terms, known failures, and areas that could not be operated or inspected

Map which system serves each part of the property

Start with a simple floor plan. Mark the equipment and the rooms, units, tenant spaces, outbuildings, and common areas each system serves. Then compare that map with thermostats, meters, lease obligations, and utility accounts. A duplex may have separate furnaces but one water heater. A storefront and apartment may share ductwork or controls. Those arrangements affect billing, maintenance access, temperature complaints, and the repair scope.

Look for spaces that were added, finished, or converted after the original system was installed. A basement room, enclosed porch, attic conversion, commercial kitchen, workshop, or new tenant use may place different demands on the equipment and ventilation. A register in the wall does not prove that the system was designed, permitted, or balanced for the space. Compare the current layout with plans, permits, and the proposed legal use.

Use the enforcing agency for the exact address

Michigan LARA says the Michigan Mechanical Code regulates the design, installation, maintenance, alteration, and inspection of mechanical systems. Its mechanical-permit page lists heating, ventilation, cooling, ductwork, refrigeration, fuel-burning appliances, chimneys, vents, and related systems within that framework. The same page explains that mechanical code enforcement may be handled by the state, a county, or a local unit of government and directs applicants to the Statewide Jurisdiction List.

That split matters in West Michigan. Nearby addresses can report to different offices. Ask the responsible agency for permit and final-inspection records tied to the property, then ask what it expects for the work under consideration. A closed permit addresses the permitted scope at a point in time. It does not prove that every later alteration was included or that the equipment is in good condition today.

LARA's page also says an appropriately classified mechanical contractor generally must perform installation, alteration, or service of listed mechanical systems, subject to a narrow provision for an owner who occupies or will occupy a single-family dwelling. An IRA-owned investment property should not be treated as though that owner-occupant provision automatically applies. Verify contractor licensing and the permit path with LARA or the local enforcing agency, and have the buyer's Michigan attorney review any uncertain ownership or occupancy question.

Give the mechanical contractor a property-specific scope

A general property inspection can identify visible concerns and basic operation, but a focused mechanical review may be needed when records are incomplete, equipment is older or altered, rooms perform unevenly, combustion or venting questions appear, or the buyer plans a different use. Give the contractor the inspection report, available service records, equipment list, floor plan, proposed use, and any seller statements that need verification.

Ask the report to distinguish what was observed, what was operated, what was measured, and what could not be tested. Outdoor temperature may prevent meaningful cooling operation. A vacant building may have winterized equipment, shut-off fuel, drained piping, or disconnected utilities. Occupied areas, locked rooms, unsafe access, roof conditions, stored materials, and concealed ducts or piping can also limit the work. Keep those limits visible instead of treating them as a pass.

The scope should follow the system rather than stop at the cabinet. That may include the heat exchanger or boiler, burner, ignition and safety controls, electrical supply, fuel connection, venting, combustion air, refrigerant components, condensate disposal, filter arrangement, blower or pumps, ducts or hydronic piping, thermostats, zoning, and visible equipment clearances. The appropriate checks depend on the equipment and building, so let the qualified professional set the safe testing method.

Treat combustion, venting, and carbon monoxide as one review

Fuel-burning equipment brings several connected questions. The appliance needs the proper fuel supply, combustion air, vent or chimney path, and operating controls for its installation. Changes elsewhere in the building can matter too. A new exhaust fan, sealed mechanical room, altered chimney, attached garage, or replacement appliance may change how air and combustion products move.

EPA describes carbon monoxide as an odorless, colorless, toxic gas. Its indoor-air guidance lists leaking chimneys and furnaces, back-drafting from furnaces or gas water heaters, and worn or poorly adjusted combustion devices among possible sources. EPA also recommends that a trained professional inspect, clean, and tune a central heating system, including furnaces, flues, and chimneys, annually. That general guidance does not diagnose one building. It does support a careful professional review of the complete combustion and venting path.

Document the location, power source, age information, and test status of carbon-monoxide alarms that are present, but keep alarm review separate from equipment inspection. An alarm is not proof that a furnace, boiler, fireplace, water heater, or vent is operating correctly. Ask the inspector, mechanical contractor, fire authority, property manager, and Michigan attorney which current alarm and maintenance requirements apply to the building and its use.

Follow air, water, and heat through the whole building

Uneven temperature can come from several places: equipment operation, duct leakage, blocked returns, poor balancing, failed zone controls, air leakage through the building envelope, insulation gaps, solar exposure, or an addition that was never integrated well. Hydronic systems add piping, pumps, valves, radiators, air removal, water pressure, and freeze protection to the review. A contractor should identify likely causes before the budget assumes that replacing the main unit will solve every room.

Trace condensate and other system water to an approved destination. Look for staining, corrosion, clogged traps, damaged pans, improvised tubing, failed pumps, floor-drain questions, and discharge near finishes or stored property. On a boiler system, ask about leaks, make-up water, expansion components, and the condition of visible piping. Mechanical findings may need coordination with plumbing, electrical, roofing, chimney, mold, or structural professionals.

West Michigan heating failures can become building failures when pipes or fire-suppression components freeze. Ask who receives low-temperature alerts, who can enter lawfully, which vendor responds, how quickly the custodian can release funds, and what temporary heat can be used safely. No one can promise the timing of a failure, so the account and property manager need a response process before cold weather tests it.

Compare the system with the proposed use

Capacity and suitability cannot be read from model numbers alone. The contractor may need building size, insulation and air-sealing conditions, windows, orientation, occupancy pattern, ventilation needs, equipment loads, zoning, and the proposed use. A plan to divide units, finish new space, change a commercial tenant, or add exhaust equipment may alter the answer. Ask whether a formal load calculation or design review is needed before relying on a replacement allowance.

For commercial or mixed-use property, identify equipment that belongs to a tenant and equipment the owner must maintain. Read leases beside the equipment map. Confirm who pays utilities, filters, routine service, major repairs, and replacement, and who can access rooftop or locked equipment. A current tenant's setup does not guarantee that the next lawful use will fit the same system, and no future tenant, rent, or occupancy is guaranteed.

Price a complete repair instead of one replacement box

Ask bidders to price the same written scope. Include equipment, controls, ducts or piping, venting, fuel work, electrical work, condensate disposal, demolition, permits, inspections, utility coordination, testing, startup, balancing, cleanup, and closeout records. Add roof work for rooftop units, finish repairs for concealed lines, and hazardous-material review when older materials may be disturbed. Different exclusions can make a lower total look more complete than it is.

Separate immediate safety or operating work from maintenance, optional improvements, and eventual replacement. Put each accepted item into the IRA budget with ordinary property expenses, including taxes, insurance, management, utilities, vacancy, and other repairs. Do not make a known mechanical cost disappear by assuming higher rent, full occupancy, lower utility bills, appreciation, refinancing, or an insurance payment. Those outcomes are not guaranteed.

Plan occupied work with consistent housing procedures

For an occupied rental, decide who receives no-heat or no-cooling reports, gives lawful notice, arranges access, authorizes emergency work, communicates service interruptions, and documents completion. Have the property manager and Michigan attorney review lease duties, local requirements, temporary arrangements, accommodation requests, and any health-related communication. Contractors decide how to perform the work safely; they do not decide the landlord's legal obligations.

HUD states that the Fair Housing Act prohibits housing discrimination because of race, color, national origin, religion, sex, familial status, or disability. Use consistent procedures for inspections, repair priorities, entry, temporary measures, and communication. Base decisions on documented building conditions, qualified recommendations, lease rights, accommodation obligations, and applicable law rather than a tenant's protected characteristics. Michigan and local protections may also apply.

Keep the work inside the IRA's process

Ask the self-directed IRA custodian how inspections, service calls, contractor deposits, permits, utility charges, repairs, warranties, insurance proceeds, refunds, and later maintenance must be authorized and paid. Confirm the purchaser name, signature authority, invoice wording, and funding lead time. If the seller will complete work before closing, have the purchase agreement define the scope, contractor qualifications, permits, inspections, access, completion records, and buyer verification.

Current IRS prohibited-transaction guidance includes selling, exchanging, or leasing property; lending money or extending credit; and furnishing goods, services, or facilities between a plan and a disqualified person. It also describes improper use of an IRA by the owner, beneficiary, or another disqualified person. Do not assume the owner can service equipment, change components, supply materials, let a disqualified person perform the work, or pay a contractor personally and seek reimbursement. The custodian, CPA, and attorney should review the people, contracts, signatures, work, and payment path before anyone acts.

No property, HVAC system, contractor, repair, ownership structure, or strategy is approved or endorsed by the IRS. Have your own self-directed IRA custodian, CPA, Michigan attorney, property inspector, licensed mechanical contractors, utilities, enforcing agency, insurer, property manager, and other qualified advisors review the account, building, records, proposed use, and work before taking action.

Leave closing with a mechanical file someone can use

Keep the equipment map, model and serial information, inspection reports, permits, final approvals, installation and service records, contractor credentials, scopes, estimates, utility correspondence, fuel records, alarm information, warranties, tenant communications, custodian instructions, and closing documents together. Add dates for follow-up work and routine service. Mark every area or operating mode that could not be inspected so the next contractor does not mistake missing information for a clean result.

Primary sources for the public-rule and safety portions of this review include Michigan LARA's Mechanical Permit Information and Code Books pages, EPA's Carbon Monoxide's Impact on Indoor Air Quality guidance, HUD's Fair Housing Act overview, and the IRS retirement-plan investment and prohibited-transaction pages. They provide the general framework. The answer for one property comes from current records, field inspection, the responsible enforcing agency, and the buyer's own qualified professionals.
