What We Do — and What We Don’t

We provide emergency HVAC inspections, furnace and water heater assessments, and equipment replacement after flooding.

We do not provide flood cleanup, sewage cleanup, water extraction, or general property restoration. If you need water removed or your basement dried, a restoration company handles that part — we handle the mechanical equipment the water damaged, and we work alongside restoration crews every day.

Emergency HVAC Services After Flooding in St. Catharines

St. Catharines has declared a state of emergency, and thousands of Niagara basements took on water. Basements are where the furnace, water heater, and ductwork live. Here’s what we handle, 24 hours a day:

Flood-Damaged Furnace Inspection

A furnace that stood in floodwater is not safe to run, even if it starts. Floodwater contaminates gas valves, control boards, and burner assemblies — and manufacturers require water-exposed gas controls to be replaced, not dried out. We inspect, test, and give you a straight answer on repair versus furnace replacement.

Hot Water Tank Assessment & Replacement

Gas controls, thermocouples, and heating elements sit low on the tank — exactly where the water was. If the waterline reached them, the tank needs replacing. We stock units and can often restore your hot water the same day.

Ductwork Inspection After Water Exposure

Ducts that took on floodwater can hold moisture, silt, and contamination, then blow it through the house once the system restarts. We inspect the ductwork before anything gets turned back on. See our ductwork services.

Air Conditioning & Heat Pump Inspection

Outdoor units hit by standing water and debris, and indoor coils or air handlers in flooded basements, both need checking before the next hot day. Full HVAC repair and safety certification.

Emergency Heat Restoration

No heat after the flood? That’s the priority call. We get safe heat back in the house as fast as parts and equipment allow — 24/7, with no after-hours premium.

Insurance Documentation

Written inspection reports for every affected appliance: waterline measurements, model and serial data, and a professional assessment of what’s repairable and what isn’t — the paperwork adjusters ask for.

Why Call an HVAC Company After a Flood?

Because a dry basement isn’t a recovered home. Restoration crews extract the water and dry the structure — that’s their job, and they’re good at it. But when they leave, the furnace, water heater, and ductwork are still damaged, and those need a licensed gas technician.

  • ✅ TSSA-licensed gas technicians — legally required for gas equipment work
  • ✅ Furnace inspection, repair, or replacement after water exposure
  • ✅ Hot water tank replacement, often same-day
  • ✅ Ductwork inspection before the system is restarted
  • ✅ Written insurance documentation for the mechanical damage
  • ✅ We coordinate directly with your restoration crew

Of everything sitting in a flooded basement, the two most expensive items are usually the furnace and the hot water tank. Those are ours.

What Happens When You Call

  1. Phone triage (24/7) — safety first: is the power off, is there a gas smell, is it safe to be in the home.
  2. Technician dispatch — a TSSA-licensed technician assesses every affected appliance.
  3. Written assessment — what’s safe, what’s repairable, what needs replacing, documented for your insurer.
  4. Repair or replacement — heat and hot water restored, often the same day for in-stock equipment.
  5. Prevention — backwater valve and equipment-elevation advice so the next storm costs you less.

Will Insurance Cover Flood-Damaged HVAC Equipment?

Sewer backup and overland water coverage are optional add-ons on most Ontario home policies — whether you’re covered depends on your specific endorsements. Furnace and hot water tank replacement are often significant line items on a flood claim, and adjusters want professional documentation. Our technicians provide written inspection reports for every affected appliance.

Not sure what your policy covers? Call anyway — 289-962-4811. We’ll document the equipment damage so you’re ready either way.

Flood-Damaged HVAC FAQs

No — treat it as unsafe until a TSSA-licensed technician inspects it. Floodwater contaminates gas valves and controls, which manufacturers require to be replaced, not dried. A furnace can run normally for weeks after a flood and then fail dangerously.

Yes — it's one of the most common post-flood jobs we do. If the waterline reached the gas control or heating elements, the tank needs replacement. We stock units and can often restore hot water the same day.

No. We do not provide water extraction, sewage cleanup, drying, or property restoration. A restoration company handles that work. We inspect, repair, and replace the heating, cooling, and hot water equipment the flood damaged, and we coordinate with your restoration crew.

We dispatch 24/7 across St. Catharines and Niagara, with same-day service wherever possible. During the state of emergency, call early — technicians are triaging by severity, and homes without heat or hot water get priority.

No. Book the HVAC inspection while drying is underway. Equipment assessments feed your insurance claim, and replacement parts and units often need ordering — starting early means heat and hot water come back sooner.

Correct — 24/7 emergency response at the same rates, including weekends. Flood emergencies don't schedule themselves.
