Furnace Repair Warning Signs Every Homeowner Should Know

The Furnace Repair Warning Signs That Mean Trouble Is Coming Fast

Your furnace is one of those things that runs in the background all winter and you barely think about it until that first really cold night when it decides to quit and then you are stuck searching for furnace repair while your house temperature drops and you are layering up every blanket in the house just to stay warm. Strange noises coming from the furnace are the most common furnace repair warning sign that people ignore for way too long because a healthy furnace should be relatively quiet and any banging popping screeching or rattling is the system telling you something is wrong and needs furnace repair attention before it fails completely. A furnace that is short cycling meaning it turns on runs for a few minutes then shuts off and starts up again a few minutes later is screaming for furnace repair because short cycling puts enormous stress on the components and wastes energy and the cause is usually a dirty flame sensor a clogged filter or an overheating heat exchanger that is tripping the safety limit switch. If your energy bills have spiked for no obvious reason and you have not changed your thermostat settings that is another furnace repair red flag because a furnace that is losing efficiency is working harder and longer to produce the same amount of heat which means something is degrading internally and needs professional furnace repair attention. Yellow or flickering flames instead of a steady blue flame in a gas furnace is a furnace repair warning sign that indicates incomplete combustion and possible carbon monoxide production which is a life threatening situation that needs emergency furnace repair immediately. Uneven heating where some rooms are toasty and others are freezing is often a ductwork issue but can also be a furnace repair problem where the blower motor is failing or the system is not producing enough heat to properly serve the whole house.

Carbon Monoxide and Other Furnace Repair Dangers You Need to Catch Early

Carbon monoxide is the scariest furnace repair issue because it is odorless colorless and deadly and a cracked heat exchanger is the usual culprit that lets combustion gases including carbon monoxide mix with the heated air that gets blown through your house. Every home with gas appliances needs working carbon monoxide detectors on every level and if those detectors go off you need to get everyone out of the house immediately and call an emergency furnace repair technician and the fire department because carbon monoxide poisoning kills hundreds of people every year and the symptoms like headache dizziness and nausea are easy to mistake for the flu. A furnace repair technician can test for a cracked heat exchanger using a combustion analyzer and a visual inspection camera and if the heat exchanger is cracked the furnace repair solution is usually a full system replacement because a cracked heat exchanger cannot be safely repaired and continuing to run the furnace is gambling with your family’s lives. Gas leaks are another furnace repair emergency that you might notice as a rotten egg smell because the gas company adds that odorant specifically so you can detect leaks and if you smell gas you need to leave the house without touching any electrical switches and call for emergency furnace repair and the gas company from outside. Regular furnace repair maintenance including an annual inspection where the technician checks the heat exchanger cleans the burners tests the safety controls and verifies proper venting is the single best way to prevent carbon monoxide dangers and keep your furnace running safely and efficiently all winter long. And if your furnace is more than fifteen years old and needing frequent furnace repair calls the cost benefit analysis usually tips in favor of replacement especially with the efficiency gains of modern furnaces that can cut your heating bills by thirty percent or more.
