24/7 Emergency HVAC Repair in St. Louis, MO

When the heat quits on the coldest night of the year or the air conditioning dies in the middle of a July heat wave, waiting until Monday is not an option. Meyer Heating & Air provides 24-hour emergency HVAC repair across the St. Louis area, 365 days a year. Our NATE-certified technicians service furnaces, air conditioners, heat pumps, boilers, and ductless systems, so a single call gets your home back to a safe temperature no matter which part of the system failed.

What Counts as an HVAC Emergency?

If a system failure is putting your safety, your health, or your home at risk, treat it as an emergency and call right away. Common HVAC emergency repair situations include:

• No heat during freezing weather: Indoor temperatures dropping toward the 50s put your family at risk and can lead to frozen and burst pipes.
• No cooling during extreme heat: A home that cannot stay cool is a serious health risk, especially with infants, older adults, or pets in the house.
• A gas smell or suspected carbon monoxide: Get everyone out of the house first, then call 911 or your gas utility. Call us once the home is clear so we can find and repair the source.
• Sparks, smoke, or a burning smell: Shut the system off at the breaker and call immediately.
• Signs of a refrigerant leak: Hissing from the lines, heavy ice buildup on the coil, or a complete loss of cooling.
• Water backing up around the equipment: A clogged condensate line can flood a basement or utility closet and cause real structural damage.
• A breaker that keeps tripping: Repeated trips point to an electrical fault that should not be reset over and over.

What to Do While You Wait for a Technician

A few steps can prevent further damage and keep your household comfortable until we arrive:

• Rule out the quick fixes. Check the thermostat setting and batteries, and confirm the breaker for the system has not tripped.
• Shut the system down if something looks or smells wrong. Ice on the unit, electrical buzzing, smoke, or a burning odor all warrant turning the system off at the breaker.
• If you smell gas, leave first. Do not flip switches or use your phone inside. Get outside, then call your gas utility or 911.
• In winter, open cabinet doors under sinks on exterior walls, let faucets drip, and close off unused rooms to hold heat where your family is.
• In summer, close blinds and curtains, run ceiling fans, skip the oven and dryer, and keep everyone hydrated.
