Heating Repair Service Near Chicago

We understand the aggravation associated with a furnace breakdown and an unresponsive heating contractor. Our friendly comfort specialists work hard to address every service inquiry and schedule appointments in a timely manner. The NATE-certified technicians at Black Diamond will accurately locate the source of the malfunction and quickly replace faulty components. The furnace repair is not complete until we verify the system is operating to the manufacturer’s original specifications. After the job is finished, our invoice amount will never exceed the final estimate.

Furnace failures are usually caused by obstructions in the ductwork, clogged filters, broken relays, or faulty ignition systems. Mechanical problems can include worn bearings, a burned-out motor, a cracked heat exchanger, or impaired burners. It is essential that the service provider is well-qualified, since some furnace components can compromise the health and safety of the home’s occupants. Our HVAC contractors can work on gas, oil, and electric furnaces.

Signs You Need Furnace Repairs

Though you may feel like your furnace is out of sight, out of mind, there are some signs your furnace will give you that it needs repairs before quitting completely. Some of those signs include:

  • Increased energy bills
  • Strange noises
  • Odd odors
  • Weak airflow
  • Frequent cycling on and off

If you notice any of these signs, contact the experts at Black Diamond to resolve the issue and get you back to the warmth of your home!

Should You Repair or Replace Your Furnace?

Furnace repairs may seem like the best option based on cost alone, but sometimes repairs may not be possible or cost-effective due to the age or condition of the furnace. The service life for a furnace is typically 12 to 15 years, though some models can last up to 20 years with good maintenance practices.

If your furnace is less than 12 years old and only has minor problems like a faulty fan limiter, a broken belt, or a defective hot surface igniter, repair will almost always be the best option. As long as your furnace has a good maintenance record, you can realistically expect several more years of service.

If your furnace is over 12 years old, however, you may want to consider furnace replacement a bit more closely, especially if any of the following are true:

  • Your furnace has become unreliable or needs frequent repairs
  • A costly part like the control board, blower motor, or heat exchanger has failed
  • The furnace cannot keep your home comfortable or is inefficient
  • The heat exchanger is cracked and is leaking carbon monoxide into your home

A new furnace can offer reduced energy usage, lower utility costs, and significantly improved comfort. Call our team today at (866) 350-4793 or contact us online to request a furnace replacement estimate!
