Why HVAC Failures Become Health Emergencies

What Makes an HVAC Failure a Health and Safety Emergency in Bay St. Louis, MS

Heat-Related Illness Risk From Extended Cooling Failure in Bay St. Louis

Indoor temperatures in a home without air conditioning in extreme summer heat can exceed outdoor temperatures by 10 to 20 degrees in Bay St. Louis, MS. At indoor temperatures above 90 degrees Fahrenheit, heat exhaustion risk increases significantly for most people in Bay St. Louis.

Hypothermia Risk From Extended Heating Failure in Cold Weather in Bay St. Louis, MS

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

Pipe Freezing Risk From Sustained Indoor Temperature Drop in Bay St. Louis

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

Carbon Monoxide Exposure From Faulty Gas Heating Systems in Bay St. Louis, MS

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