24/7 Emergency HVAC Repair in Marietta, GA

Heating or cooling failure that can't wait? We provide fast, around-the-clock emergency HVAC repair across Marietta and Metro Atlanta — day, night, weekends, and holidays.

When your system fails on the hottest afternoon or the coldest night, you don't have time to wait days for an appointment. Ultimate Home Services Plus answers emergency calls 24/7 and gets a technician to your Marietta home as fast as possible.

HVAC systems rarely break down at a convenient time — it's almost always during a heat wave or a hard freeze, when they're working hardest. A no-cool day in a Georgia summer or a no-heat night in winter isn't just uncomfortable; for young children, older adults, and pets it can become a real safety concern. That's why we keep the line open when other shops are closed.

When to Call for Emergency Service

No cooling during extreme heat — especially dangerous for vulnerable household members.
No heat during a freeze, with the risk of burst pipes.
A gas smell or suspected carbon monoxide — leave the home and call immediately.
Burning smells, smoke, or sparking from the system.
Water leaking from the unit and threatening floors or ceilings.
A complete system shutdown that won't restart.

What to Do While You Wait

Safety first — if you smell gas or suspect carbon monoxide, get everyone outside and call your gas utility and us.
Shut the system off if it's leaking, sparking, or making alarming noises — running it can cause more damage.
Check the simple things — thermostat setting, breaker, and the furnace/AC switch.
Stay comfortable — close blinds in heat, layer up in cold, and keep vulnerable family members in the most comfortable room.

Then call us at 404-484-0412 and we'll walk you through the rest.
