Key warning signs include a strong, unusual odor (similar to formaldehyde), visible soot around the furnace, rust on the vent pipe, or the burner flame appearing yellow instead of blue. A cracked heat exchanger is a serious safety issue as it can allow carbon monoxide to enter your home. If you notice any of these signs, it's crucial to turn off your furnace and call us immediately for a professional inspection.

If your air conditioner is blowing warm air, icing up, or making a hissing sound, a refrigerant leak is a likely cause. Refrigerant is the lifeblood of your cooling system, and a leak reduces efficiency and can cause costly compressor failure. Our technicians use specialized tools to locate and repair leaks, then recharge the system with the precise amount of refrigerant specified by the manufacturer to restore optimal cooling performance.

Our comprehensive maintenance service is designed to catch small issues before they become major repairs. We clean critical components, check for early signs of wear like stress on heat exchangers, test refrigerant pressure to spot leaks, and ensure safe operation. This proactive approach not only improves safety and efficiency but also extends the life of your equipment, saving you money and preventing inconvenient breakdowns during peak seasons.
