24/7 Emergency HVAC Repair in Vaughan

Tell us whether it’s your furnace, air conditioner, water heater or another urgent home-comfort issue. We’ll collect the essentials and follow up as soon as possible.

Before you submit

Choose the closest match

Common signs help us understand what you may need before we arrive.

No heat

Furnace will not start, blows cold air, cycles repeatedly or makes unusual sounds.

No cooling

AC blows warm air, airflow is weak, the outdoor unit stops or ice appears.

No hot water

Water stays cold, runs out quickly, temperature fluctuates or the tank leaks.

Other urgent issue

System shutdown, burning smell, water leak or another comfort concern.

Smell gas or suspect carbon monoxide?
Leave the area, call 911 or your gas utility from a safe location, and do not operate switches or equipment.

While you wait for follow-up

Protect people, provide access and avoid unsafe troubleshooting

These steps are general preparation only. They do not replace emergency services or a qualified assessment.

Put safety first

For gas, carbon monoxide, smoke, fire or immediate danger, leave the area and call 911 or the appropriate utility from a safe location.

Do not bypass the system

Avoid removing panels, repeatedly resetting equipment, operating unfamiliar valves or defeating safety switches.

Gather useful details

Note the affected equipment, error code, sounds, smells, visible water, operating pattern and when the change began.

Urgency indicators

Warning signs that change the next step

Some comfort problems can wait for ordinary follow-up; others require a phone call or emergency services. Use the safest path when conditions are uncertain.

Leave and call emergency services

Gas odour, a carbon-monoxide alarm, smoke, fire or immediate danger means leaving the area and calling 911 or the appropriate utility from a safe location.

Call the HVAC service line

Complete loss of heat, cooling or hot water, active leakage, repeated shutdown or a new burning odour should be discussed directly rather than left in an online queue.

Share household vulnerability

Tell the team when infants, older adults, medical needs or severe indoor conditions make the comfort loss more urgent so the situation can be understood accurately.

Urgent-service questions

What to know before requesting urgent HVAC help

Clear information helps you decide when to call and what to expect next.

Should I use the form for an active gas or carbon-monoxide emergency?

No. Leave the area and call 911 or the appropriate gas utility from a safe location. Do not operate switches or equipment.

What information should I provide?

Share the affected system, the symptoms, when the problem started, your contact details and the service address.

Is an online request a confirmed appointment?

No. A team member must review the request and confirm the next step. Calling is the fastest option for an active comfort-system breakdown.

Ready for a clear next step?

Tell us what changed in your home.

Describe the system and symptoms. M&M Home Comfort will review the request and help identify the appropriate service path.
