Signs Your Furnace May Need Repair

Contact a qualified furnace technician if you notice:

  • The furnace will not start
  • The system is running but producing little or no heat
  • Some areas of the property remain colder than others
  • The furnace turns on and off unusually often
  • Airflow from the vents has become weak
  • The system is making banging, rattling, grinding, or squealing sounds
  • There is an unusual burning or electrical odour
  • Heating costs have increased without an obvious explanation
  • The thermostat and furnace do not appear to be communicating properly


When planning a furnace installation in Windsor, our team assesses the property and helps identify an appropriate heating solution. The objective is consistent comfort and reliable performance, not installing equipment that is unnecessarily large or poorly suited to the building.

When a Furnace Problem Becomes Urgent

A loss of heat during freezing weather should be addressed promptly, particularly in properties occupied by seniors, young children, or anyone vulnerable to cold temperatures.



Burning smells, visible electrical damage, repeated breaker trips, unusual combustion behaviour, or a carbon monoxide alarm also require immediate attention. If you suspect a gas or carbon monoxide emergency, leave the affected area and follow the instructions of your gas utility or emergency services before arranging routine HVAC service.

Frequently Asked Questions

See some of the most common questions we get from our clients.

  • How do I know whether my furnace needs repair or replacement?

    That depends on the system’s condition, age, repair history, performance, and the cost of the required work. A professional assessment can help you compare the value of another repair with the benefits of replacement.

  • How often should a furnace be maintained?

    Possible causes include restricted airflow, dirty coils, thermostat problems, electrical faults, refrigerant-related issues, or a failing component. Because several problems can cause similar symptoms, proper diagnosis is important.

  • Why does my furnace keep turning on and off?

    Yes. M&M Global provides commercial hvac services including cooling repair, installation, maintenance, and mechanical support for businesses and properties throughout Windsor and Essex County.

  • Do you service different furnace makes and models?

    Describe the item or answer the question so that site visitors who are interested get more information. You can emphasize this text with bullets, italics or bold, and add links.

  • Can you help with commercial furnace systems?

    Schedule preventive maintenance, replace filters as required, keep outdoor equipment clear of debris, and arrange service when you notice changes in airflow, temperature, sound, cycling, or system operation.

  • Is furnace maintenance included with a preventive maintenance plan?

    Plan coverage will depend on the selected maintenance arrangement and equipment. Contact M&M Global to discuss your furnace, other HVAC systems, and an appropriate service schedule. Our team is always happy to talk!
