Emergency HVAC Repair in Howell, MI 48843 - Dean's Heating & AC

First, check that your thermostat is set to 'heat' and the temperature is set higher than the room temperature. Ensure your furnace's power switch is on and the circuit breaker hasn't tripped. If these are fine, it's likely an issue with the ignition system, gas valve, or flame sensor—common problems during our harsh winters. Don't attempt to fix gas or electrical components yourself. Call us immediately for a safe, professional diagnosis and repair to restore your heat quickly.

Signs of a refrigerant leak include reduced cooling, ice forming on the refrigerant lines or evaporator coil, and a hissing or bubbling sound. This is a serious issue because low refrigerant makes your AC work harder, increasing energy bills and causing wear that can lead to a complete breakdown. More importantly, refrigerants are regulated substances. Our certified technicians can safely locate the leak, repair it, and recharge your system to the manufacturer's exact specifications, restoring efficiency and protecting your investment.

Regular preventative maintenance is key. Before winter, we recommend a furnace tune-up that includes cleaning the flame sensor and checking the ignition system and heat exchanger to prevent ignition failures. Before summer, an AC check should include inspecting coils, checking refrigerant levels, and cleaning the system to maintain efficiency and spot potential leaks early. Our seasonal maintenance plans are designed specifically for our local climate to catch small issues before they become costly, uncomfortable emergencies.
