Why HVAC Failures Become Health Emergencies

What Makes an HVAC Failure a Health and Safety Emergency in Mehlville, MO

Heat-Related Illness Risk From Extended Cooling Failure in Mehlville

Indoor temperatures in a home without air conditioning in extreme summer heat can exceed outdoor temperatures by 10 to 20 degrees in Mehlville, MO.

Children under 4 and adults over 65 are at significantly elevated risk in Mehlville, MO.

Hypothermia Risk From Extended Heating Failure in Cold Weather in Mehlville, MO

At indoor temperatures below 50 degrees Fahrenheit, hypothermia risk increases for elderly individuals and infants in Mehlville. At indoor temperatures below 40 degrees, hypothermia risk is present for most people without adequate cold weather clothing in Mehlville, MO. A home that reaches 32 degrees indoors is a medical emergency for any occupant in Mehlville.

Pipe Freezing Risk From Sustained Indoor Temperature Drop in Mehlville

Water pipes in exterior walls and crawl spaces begin freezing when the surrounding temperature drops below 32 degrees Fahrenheit in Mehlville, MO. A burst pipe in a home without heat produces water damage that can significantly exceed the cost of the original HVAC repair in Mehlville. Prompt emergency HVAC repair prevents the heating failure from becoming a combined HVAC and water damage emergency in Mehlville, MO.

Carbon Monoxide Exposure From Faulty Gas Heating Systems in Mehlville, MO

Carbon monoxide from a cracked heat exchanger accumulates in the home's air with every heating cycle in Mehlville. Symptoms including headache, dizziness, and nausea develop as exposure continues in Mehlville, MO. At sufficient concentrations, carbon monoxide exposure is life-threatening in Mehlville. If the CO alarm has activated or household members are experiencing symptoms consistent with CO exposure, evacuate immediately in Mehlville, MO.

FAQ

Emergency HVAC Repair FAQs in Mehlville, MO

For a heating emergency in cold weather in Mehlville: gather household members in one interior room, use blankets and layers to maintain body warmth, open cabinet doors under sinks on exterior walls to reduce pipe freezing risk, and avoid using gas ovens for heating in Mehlville, MO.
