Signs It's Time To Repair Your Furnace

The St. Louis-based heating systems contractor Hoffmann Brothers prescribes a furnace inspection if you notice the following scenarios:

Inflated energy bills. Even as certain utility and energy companies are raising prices across the country, higher utility bills are often an indication that something is wrong with the furnace.

Continual thermostat resetting. A need to continually raise the thermostat to higher temperatures is another sign that something may not be working properly with the furnace. Sometimes it’s a matter of replacing air filters with a new one.

Broken parts. When the furnace’s heat exchanger is cracked or the burner is improperly burning fuel, it can release carbon monoxide. The symptoms of carbon monoxide often mimic those of the flu. Individuals afflicted with CO poisoning feel lethargic, weak and nauseous.

Faulty pilot lighting. An inability to keep the pilot light on is another sign of a faulty furnace, necessitating the expertise of a licensed and certified HVAC contractor.

Furnace continually cycles. Although many HVAC experts attribute a broken thermostat as the cause of a perpetually cycling furnace, it is still advisable to contact a heating systems contractor to evaluate the unit.

Leaking gas. The smell of gas near the furnace requires the immediate attention professional, as a leaking furnace can be detrimental to a household’s safety.

Furnace Heat Exchanger Repair for St Louis Properties

A furnace heat exchanger is the portion responsible for separating the air that you breathe from the toxin-producing combustion happening at the same time. The air in your St Louis area home or business blows across the hot metal surface of a heat exchanger, gets heated and then distributed throughout the property to provide warmth.

Furnace heat exchangers can and do fail, mainly due to fatigue of the metal involved. A typical shelf life for these is between 10-20 years, but they do require maintenance. If you suspect a failure or malfunction of these furnace systems, Hoffmann Brothers can provide experienced furnace heat exchanger repair by our team of trained technicians. Call us today and we’ll be happy to investigate and provide a full repair or best next steps should your unit merit furnace replacement.

Why Is My Furnace Blowing Cold Air?

If your furnace is blowing cold air, the good news is your blower is working. This fact provides little comfort as the temperature drops outdoors in St. Louis, MO. Here are some potential reasons your furnace could be malfunctioning and solutions to help solve your problem.

Did you just switch your furnace on?
If your furnace has been dormant since last heating season, be patient. Like preheating your oven, it takes a few moments for warmer air to stream from your vents. Remember the parking in tandem rule. Existing cold air must exit the vents first, followed by warm air.

You turned on a furnace in the basement that needs to activate, blow air over the heat exchanger to warm it, and send the warm air to your ductwork to displace the existing cold air. The air flowing from your vents should change from cold to warm momentarily.

Have you checked your thermostat?
Your thermostat provides two clues to a case of cold air. First, ensure your system is neither off nor in cooling mode, it should be on heating mode. Second, the fan may be ON rather than AUTO mode. ON is not a problem, but realize the air continues to circulate whether it’s being conditioned or not.

When was the last time you had your furnace serviced or replaced the air filter?
An annual furnace check is always recommended. Besides restoring your St. Louis furnace to peak efficiency, damage is addressed early and all parts are cleaned. If you haven’t replaced your furnace air filter regularly, it may be dirty. A clogged air filter can damage the heating components of your furnace. The damage can accumulate and cause furnace failure.

Is Your Furnace Sensor Covered with Dirt?
One of the common reasons for cold blowing air from a furnace is a dirty sensor. The sensor detects the burner. If a lit burner goes undetected, the gas supply to your furnace is shut off as a safety precaution. No gas equals cold air from your furnace. In the same way, an extinguished pilot light on older furnaces shuts off the gas.

Whether the solution to cold air from your furnace is simple or complex, a Hoffmann Brothers qualified HVAC contractor can help. Call (314) 664-30111 in St. Louis, MO. for a reliable fix when your furnace is blowing cold air.

Pay Attention to Unusual Burning Smells In Furnace

A burning smell from your furnace may sometimes fit the alarm category.

When a Furnace Burning Smell is Normal
A burning smell from your furnace the first time you flip it on for the season is normal. Dust accumulates on the components of your heating system during its dormant seasons. When you switch the furnace into operation, the dust is scorched and the smell travels through your ductwork.

Expect the burning smell to last for a couple of hours. One tip is to turn on your furnace on a mild day when you can open the windows.

When a Furnace Burning Smell is Bad
Sometimes a burning smell from your furnace shouldn’t be ignored. “If the smell after you switch on the furnace for the first time doesn’t dissipate, the problem may be larger than an initial layer of dust,” warns a licensed contractor in Fenton, MO.

A burning smell could be due to a clogged air filter. A dirty filter isn’t doing its job of removing the dust, so the dust burning continues. In addition, a clogged filter causes the furnace to work too hard. Components like the blower can’t achieve adequate air flow across the heat exchanger. Your heating system parts can overheat.

Some burning smells originate from the electrical components of your heating system. Worn electrical parts can overheat and cause a fire.
