Dan's Service: Qualified HVAC Repair Serving Somerville, MA 02143

Key warning signs include a yellow or flickering burner flame, sooty stains around the furnace, and excessive condensation on windows. More serious symptoms like headaches or nausea in the home are a major red flag. Dan's Service performs thorough safety inspections, checking heat exchangers for cracks, ensuring proper venting, and testing for CO levels. We provide the expert maintenance and repairs needed to eliminate these risks and keep your Somerville home safe.

In our area, a frequent culprit for ignition failure is a dirty or faulty flame sensor, which safety shuts the system down if it doesn't detect a flame. Other common issues include a faulty igniter or a blocked condensate line. A Dan's Service technician will first diagnose the exact cause, clean or replace the sensor if needed, and ensure all ignition components are functioning correctly. We get your heat restored quickly to protect your home from freezing temperatures.

We recommend an annual professional tune-up, ideally in the fall before heating season. This preventative visit allows our technicians to clean critical components, test safety controls (including carbon monoxide production), check for wear, and ensure efficient operation. This regular maintenance by Dan's Service is the best way to catch small problems before they lead to a no-heat situation or a safety hazard during a Somerville cold snap.
