Blanchette's Heating And Cooling | Reliable HVAC Services in Gilmanton, NH

Not necessarily. Thermostat malfunctions are a common issue here and often don't require a full system replacement. We'll first diagnose if it's a simple thermostat calibration, wiring issue, or battery problem. If your system is over 15 years old and inefficient, a replacement might be recommended for long-term savings and reliability, but we always provide a clear, honest assessment of your most cost-effective option.

Annual maintenance is your first line of defense. During a tune-up, our technicians meticulously inspect your furnace's heat exchanger for cracks, check the flue for proper ventilation, and ensure the system is burning fuel correctly. These steps are critical for detecting issues that could lead to dangerous carbon monoxide leaks. For added safety, we always recommend installing CO detectors on every level of your home, especially near sleeping areas.

While maintenance is preventative, repairs address active problems. Watch for signs like uneven heating/cooling, strange noises (banging, screeching), a sudden spike in energy bills, or the system constantly cycling on and off. Any smell of gas or burning is an immediate red flag—shut off the system and call us right away. If your thermostat is unresponsive or your pilot light frequently goes out, these are also clear signals a professional repair is needed to restore safety and efficiency.
