Gregoire & Sons | Trusted HVAC Repair in Sanford, ME

A cracked heat exchanger is a serious safety hazard, as it can leak carbon monoxide into your home. Warning signs include a strange, chemical-like smell from your furnace, visible soot around the burner, or your furnace shutting off unexpectedly. If you notice any of these issues, turn off your furnace immediately and call us for a professional inspection. Our technicians use specialized tools to safely detect cracks that aren't visible to the naked eye.

Improving indoor air quality starts with your HVAC system. We recommend regular maintenance, including changing your air filters monthly during peak seasons. For Sanford homes, we often suggest installing advanced air purification systems or UV lights within your ductwork to neutralize allergens, mold spores, and bacteria. A professional duct cleaning from our team can also remove accumulated dust and debris that recirculates through your home, making a noticeable difference for family members with allergies or asthma.

Maine's harsh winters and variable seasons put significant strain on heating and cooling systems. Preventative maintenance, performed twice a year (before heating and cooling seasons), is crucial. It ensures your system runs efficiently to manage high energy costs, catches small issues like a dirty flame sensor or low refrigerant before they become major repairs, and verifies safety components like the heat exchanger are intact. This proactive care extends your system's lifespan and provides peace of mind during our coldest months.
