HVAC Emergency in London, ON?

Call for Emergency Service Immediately If You Notice:

1. You Smell Gas or "Rotten Eggs"

This is the most critical emergency. Natural gas is odorless, so utility companies add a substance called mercaptan to give it a distinct rotten egg smell. If you detect this odor near your furnace or anywhere in your home:

1. Do NOT operate any electronics, light switches, or lighters.
2. Evacuate everyone from the house immediately.
3. From a safe distance, call your gas utility's emergency line (e.g., Enbridge Gas at 1-866-763-5427).
4. After contacting the utility, call us for 24/7 furnace repair to address the appliance.

2. No Heat During Freezing Temperatures

In a Southwestern Ontario winter, a complete loss of heat is a serious threat. When temperatures outside are below freezing, a home without heat can quickly become dangerously cold, posing a risk to your family and your property.

• Risk to Property: The primary danger is frozen and bursting pipes, which can cause thousands of dollars in water damage.
• Our Response: Hawana HVAC prioritizes no-heat calls in winter to get your system running and protect your home. This is a clear-cut HVAC emergency in London, ON.

3. No Air Conditioning During a Heat Wave

While often seen as a comfort issue, a lack of cooling during an extreme heat advisory can be a health emergency, especially for households with young children, the elderly, or individuals with medical conditions. If your AC fails completely on a 30°C+ day, you need emergency AC repair.

4. Loud Banging, Grinding, or Squealing Noises

Your HVAC system should operate with a gentle hum. Loud, sudden, and persistent mechanical noises are a sign of serious internal damage.

• Banging or Popping: Could be a major issue with the ignition or a broken component inside.
• Grinding or Scraping: Often indicates a broken motor bearing or fan blade.

Action: If you hear these noises, shut off your system at the thermostat and the breaker immediately to prevent further damage and call for service.

What Might NOT Be an Emergency?

Some issues, while frustrating, can often wait for a regular service appointment:

• A single vent isn't blowing air: This could be a blockage or damper issue, not system failure.
• Your system is a little noisier than usual: Minor rattling can often wait unless it's a sudden, loud noise as described above.
• A minor water leak from your AC in summer: If you can contain the drip with a pan, it's likely a clogged drain line that can be addressed during business hours.
