Heating and A/C companies

Floodwater and smoke can ruin furnaces, air handlers and outdoor units, and a house being dried out depends on its heating and cooling. These companies repair or replace the equipment.

Heating and cooling after a flood or fire

Furnaces, boilers, water heaters and air conditioners that sat in flood water should not be switched back on until a professional has inspected them. Gas controls and valves that were under water can fail dangerously, and the US Consumer Product Safety Commission advises replacing them rather than drying them out.

After a fire, smoke and soot reach the air handler, coils and ductwork, and the system can keep spreading odor until it is cleaned. A house being dried out also depends on its heating and cooling, so the equipment is often one of the first repairs.

What the federal agencies say about flooded heating equipment

These points come from the pages we read on 10/05/2026 and are linked, with the date each page shows. They are general guidance, not advice for your home.

  • Replace gas controls that were under water. The CPSC says: "Before using your appliances, have a professional or your gas or electric company evaluate your home and replace all gas control valves, electrical wiring, circuit breakers, and fuses that have been under water." (CPSC, flood victims, July 11, 2023)
  • They cannot be dried out. In a 1997 release the CPSC said: "Gas control valves that have been under water cannot be salvaged; they must be replaced," and that fans, motors, electric circuits and venting systems "should be evaluated by a qualified technician for continued safe operation." (CPSC, warning to flood victims, March 6, 1997)
  • If you smell gas. "If you smell or hear gas leaking, leave your home immediately and contact local gas authorities from outside the home." (CPSC, July 11, 2023)
  • Carbon monoxide. Ready.gov says: "Install working carbon monoxide detectors on every level of your home." (Ready.gov, power outages, updated 06/04/2026)

Questions to ask before you hire

Will you inspect the equipment before it is turned back on?

Ask for an inspection of anything that was under water or exposed to smoke before the system runs again.

Repair or replace?

Ask what can be repaired, what has to be replaced, and why, with prices for both where there is a choice.

Are you licensed and insured?

HVAC licensing rules differ by state. Ask what applies where you live, and ask for proof of liability insurance.

What warranty comes with the work?

Ask what the equipment and the installation are each warranted for, and for how long.

Does Restoration Advertising check these companies?

No. The companies supplied their own listings, and the directory does not rate, rank or vet them. That is why the questions above are worth asking whoever you call.
