D J Heating & Cooling: Experienced HVAC Services Serving Livonia, MI 48150

Frozen HVAC components are often caused by restricted airflow or low refrigerant. We recommend regular maintenance, including checking and replacing dirty air filters monthly during high-use seasons. Our Livonia technicians perform thorough inspections to ensure proper refrigerant levels and clear drain lines, preventing ice buildup and protecting your system from costly damage during our harsh winters.

Key warning signs include a yellow, flickering burner flame (instead of steady blue), soot or rust around the furnace or vent pipe, excessive condensation on windows, and a stale, stuffy smell. Most importantly, if household members experience flu-like symptoms (headaches, nausea, dizziness) that improve when leaving the house, evacuate immediately and call 911, then call us for a professional safety inspection of your Livonia home's heating system.

Annual maintenance is your first line of defense against both safety hazards and system failures. Our tune-up includes cleaning critical components, checking for gas leaks and carbon monoxide risks, testing safety controls, and ensuring efficient operation. This proactive service helps prevent unexpected breakdowns during freezing temperatures, improves energy efficiency to lower your bills, and most importantly, ensures your family's safety throughout the heating season.
