When your heating system fails during a cold Massachusetts winter, it’s more than an inconvenience—it’s an emergency. A sudden loss of heat can disrupt your family’s comfort, compromise your home’s safety, and lead to more significant problems like frozen pipes. For homeowners in Wellesley, a reliable, fast-acting heating repair service isn’t a luxury; it’s a necessity. Lavallee Systems specializes in providing prompt, professional heating repairs for furnaces, boilers, and heat pumps, ensuring your home remains a warm and comfortable sanctuary all winter long.

With a deep understanding of the unique heating needs of Wellesley homes, Lavallee Systems is equipped to handle any challenge your system presents, from minor malfunctions to complete system breakdowns.
Sometimes, a heating system fails without warning. More often, however, it provides subtle clues that a problem is developing. Recognizing these signs early can help you avoid a complete shutdown and more costly repairs down the line. If you notice any of the following issues, it’s time to call Lavallee Systems for an inspection and repair.

Are some rooms in your house warm while others remain cold? Does the air blowing from your vents feel lukewarm or cool? This often indicates issues with the blower motor, ductwork, or the heating element itself.
Your heating system should operate with a relatively low, consistent hum. Banging, rattling, screeching, or grinding sounds are clear signs of mechanical problems. These noises can point to a loose component, a failing motor, or a problem with the ignition system.
A faint smell of burning dust when you first turn on your furnace for the season is normal. However, a persistent burning smell, the scent of rotten eggs (a sign of a gas leak), or musty odors from the vents suggest serious issues that require immediate attention from Lavallee Systems.
If your heater turns on and off more frequently than usual, it’s known as short cycling. This not only puts excessive wear and tear on your system but also drives up your energy bills. It can be caused by a clogged filter, a faulty thermostat, or an oversized unit.
A sudden, unexplained spike in your utility bills is often the first sign that your heating system is losing efficiency. It has to work harder and longer to produce the same amount of heat, indicating an underlying problem that needs to be repaired.
An increase in dust, allergens, or dry air inside your home can be linked to a malfunctioning heating system. Problems with the filter, humidifier, or ductwork can impact the quality of the air you breathe.
Lavallee Systems is equipped to diagnose and repair all types of heating systems commonly found in Wellesley homes. Our technicians receive continuous training to stay current with the latest technology and repair techniques for all major brands and models.
Furnaces are the most common type of heating system in the area. Our team has extensive experience resolving all furnace issues, including pilot light or electronic ignition failures, malfunctioning thermostats, cracked heat exchangers, and blower motor problems. We ensure your furnace operates safely and efficiently.
Boilers provide reliable radiant heat, but they can develop unique problems. Lavallee Systems technicians are experts in diagnosing and repairing boiler issues such as kettling (loud banging noises), leaking water, loss of pressure, and radiator cold spots. We work with both gas and oil boilers, restoring their consistent and comfortable heat.
Heat pumps are versatile systems that provide both heating and cooling. Common repair needs include a system stuck in one mode, refrigerant leaks, frozen outdoor coils, and electrical connection failures. Our technicians can quickly identify the root cause and perform the necessary repairs to get your heat pump running correctly.
