Why HVAC Failures Become Health Emergencies

What Makes an HVAC Failure a Health and Safety Emergency in Aliso Viejo, CA

Heat-Related Illness Risk From Extended Cooling Failure in Aliso Viejo

Indoor temperatures in a home without air conditioning in extreme summer heat can exceed outdoor temperatures by 10 to 20 degrees in Aliso Viejo, CA. At indoor temperatures above 90 degrees Fahrenheit, heat exhaustion risk increases significantly for most people in Aliso Viejo. Children under 4 and adults over 65 are at significantly elevated risk in Aliso Viejo, CA.

Hypothermia Risk From Extended Heating Failure in Cold Weather in Aliso Viejo, CA

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

Pipe Freezing Risk From Sustained Indoor Temperature Drop in Aliso Viejo

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

Carbon Monoxide Exposure From Faulty Gas Heating Systems in Aliso Viejo, CA

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