HVAC Services Mantorville MN | Call Comet Heating & Air

Often, thermostat issues like an unresponsive display or incorrect temperature readings are due to simple fixes such as dead batteries, tripped breakers, or calibration problems. Our technicians will first diagnose the root cause. If a repair isn't feasible or you have an outdated model, we'll explain your replacement options, including modern programmable or smart thermostats that can improve your home's efficiency.

A frequently extinguished pilot light is often a sign of a dirty thermocouple, a draft, or issues with the gas supply. While a relit pilot light might seem harmless, it can indicate a safety concern, such as a faulty gas valve. For your safety, we recommend calling us for a professional inspection. We'll clean or replace the necessary components and ensure your furnace is operating safely and reliably.

Before you call, a quick check can help: First, ensure your thermostat is set to 'Heat' and the temperature is set higher than the current room reading. Next, check your home's circuit breaker to see if the furnace switch has tripped. Finally, if you have a gas furnace, verify that the pilot light is lit. If these steps don't resolve the issue, give Comet Heating & Air a call—we'll get to the bottom of it promptly.
