Notice These Furnace Problems? Call Us

Your heating system gives off warning signs when it’s struggling, and catching these issues early can save you from expensive repairs or a complete system failure. If your furnace is blowing cold air, cycling on and off too frequently, or making unusual noises like banging or screeching, it’s time to give us a call. These symptoms can signal anything from a malfunctioning thermostat to a failing blower motor or heat exchanger.

Another common issue involves uneven heating. If one room feels like a sauna while another feels like an icebox, there may be a problem with your ductwork, thermostat settings, or the furnace itself. Poor air quality, indicated by excessive dust, unpleasant odors, or increased allergy symptoms, can also point to a problem within your heating system, such as a clogged filter or dirty burners.

Higher-than-usual energy bills without an obvious cause can also suggest your furnace isn’t operating efficiently. This could stem from a variety of issues, such as worn-out components or a lack of routine maintenance. Our technicians can diagnose the problem quickly and offer a solution that gets your system back on track.

Common Heating System Repairs

At EM Energy & Air, we’re familiar with all major heating system brands, including Lennox, Trane, and Rheem, and we have extensive experience handling a wide range of repairs.

Ignition System Failures

Modern furnaces often rely on electronic ignition systems, which can sometimes malfunction. Whether it’s a hot surface ignitor that has worn out or a pilot light that won’t stay lit, ignition problems can prevent your furnace from heating properly. These issues require a professional touch to safely restore functionality and ensure your system operates efficiently.

Blower Motor Repairs

The blower motor is responsible for circulating warm air throughout your home. When this component fails, you may notice weak airflow, unusual noises, or no airflow at all. Blower motor repairs typically involve lubricating bearings, replacing worn-out belts, or installing a new motor if the damage is severe.

Heat Exchanger Cracks

A cracked heat exchanger is one of the most serious furnace problems, as it can leak carbon monoxide into your home. Signs of a damaged heat exchanger include soot around the furnace, a strong odor resembling formaldehyde, or your carbon monoxide detector going off. This repair requires immediate attention to protect your household’s safety.

Thermostat Malfunctions

A faulty thermostat can disrupt your heating system’s ability to maintain consistent temperatures. Whether the thermostat is unresponsive, reading the wrong temperature, or failing to communicate with your furnace, we can repair or replace it to restore proper operation.

Ductwork Leaks

Leaky ducts can cause warm air to escape before it reaches your living spaces, leading to uneven heating and higher energy bills. Our team can locate and seal these leaks, improving your system’s efficiency and keeping your home consistently warm.

Burner Cleaning and Repairs

Dirty or malfunctioning burners can reduce your furnace’s ability to generate heat, and they can also contribute to poor air quality. Cleaning the burners or replacing damaged components can restore your system’s performance and improve the air you breathe.

Limit Switch Replacements

The limit switch monitors your furnace’s internal temperature and shuts the system off if it overheats. A failing limit switch can cause your furnace to run continuously or not at all. Replacing this small but important part can help prevent further damage to your system.
