Prevent carbon monoxide leaks, electrical fires, and $2,000+ repairs by recognizing HVAC warning signs most homeowners miss completely.

Summary:
Gas furnaces and water heaters produce carbon monoxide when heat exchangers develop cracks or combustion air becomes restricted, creating invisible threats that cause headaches, dizziness, and death in severe cases. Heat exchanger inspection requires professional equipment to detect hairline cracks that allow combustion gases to mix with circulated air throughout your home. Improper venting allows carbon monoxide to accumulate in basements, crawl spaces, and living areas where families spend time unaware of the deadly gas building up around them. Blocked flue pipes from bird nests, debris, or structural damage prevent proper exhaust ventilation, forcing dangerous gases back into your home’s air supply. Insufficient combustion air from sealed homes or blocked air intakes causes incomplete burning that produces higher carbon monoxide levels while reducing heating efficiency. Gas pressure problems from utility supply issues or regulator failures create incomplete combustion that generates dangerous gas levels even in properly functioning equipment. Carbon monoxide detectors provide early warning but cannot prevent the source problems that create these dangerous conditions in the first place. Professional combustion analysis measures actual gas production levels and identifies problems before they reach dangerous concentrations that threaten your family’s safety.
Electrical connections in HVAC systems carry high amperage loads that generate heat and create fire hazards when connections loosen or corrode over time. Overheated contactors, relays, and wire connections start electrical fires that spread rapidly through homes, particularly in attic installations where combustible materials surround equipment. Arc faults from damaged wiring create sparks that ignite insulation, ductwork, and structural materials without warning. Capacitor failures release toxic chemicals while creating electrical shorts that damage expensive compressors and motors.
Mold growth in ductwork and air handlers creates spores that circulate throughout your home, triggering asthma attacks and respiratory infections in sensitive individuals. Bacterial growth in condensate drains produces toxic compounds that cause legionnaires’ disease and other serious illnesses. Pest infestations in ductwork introduce allergens, disease vectors, and contamination that affects air quality for months after removal. All Fresh Temp technicians use specialized equipment to detect biological contamination before it spreads throughout your home’s air system.

Refrigerant leaks create both environmental damage and health risks while destroying expensive HVAC equipment through inadequate cooling and overheating problems. R-410A refrigerant displaces oxygen in enclosed spaces, creating suffocation hazards in basements and mechanical rooms where leaks accumulate without ventilation. Older R-22 systems contain refrigerants that damage ozone layers and carry significant replacement costs as production phases out completely. Refrigerant detection requires specialized electronic leak detectors that identify problems at 0.5 ounce per year leak rates—levels that cause equipment damage but remain undetectable through visual inspection. Indoor coil leaks release refrigerant directly into your home’s air supply, while outdoor leaks contaminate soil and groundwater around your property. Compressor damage from low refrigerant levels creates expensive repairs averaging $2,000-3,500 that could be prevented through early leak detection and repair. Improper refrigerant handling during repairs releases toxic vapors and violates EPA regulations that carry substantial fines for homeowners and contractors. All Fresh Temp technicians use electronic leak detection equipment and proper recovery procedures to identify problems early while protecting both your family’s health and the environment from contamination.
Combustion analysis testing measures carbon monoxide production, oxygen levels, and draft conditions to verify safe operation of gas-fired equipment. Electronic leak detection identifies refrigerant leaks at levels invisible to human senses but dangerous to equipment and environment. Electrical testing using thermal imaging reveals overheated connections before they cause fires, while amp draw testing identifies motor problems before catastrophic failures occur. Biological sampling of ductwork and air handlers detects mold, bacteria, and pest contamination that affects indoor air quality.
Carbon monoxide detector installation in sleeping areas and near equipment provides early warning of dangerous gas accumulation, while proper detector maintenance includes monthly testing and annual battery replacement. Emergency shutdown procedures include knowing gas valve and electrical disconnect locations for immediate system isolation during dangerous situations. Professional emergency services from All Fresh Temp provide 24/7 response for carbon monoxide alarms, gas leaks, and electrical hazards that threaten immediate safety.
