Regular maintenance is crucial for the optimal performance and longevity of your furnace. As a general guideline, you should schedule maintenance at least once a year, ideally before the heating season starts. This helps ensure that your furnace is in good working condition and can handle the increased workload during the colder months.  It is recommended to have annual maintenance starting one year after the furnace is install but especially important when 10-15 years for safety reasons and prevent carbon monoxide concerns. Please note that to maintain your manufacturer warranty, annual maintenance is required. Some signs that your furnace may need maintenance include: Strange noises: If you hear unusual noises, such as banging, squealing, or rattling, it may be an indication that something is wrong with your furnace and requires attention from our technicians. Uneven heating: If some rooms in your home are warmer or colder than others, it could be due to poor airflow or issues with the furnace itself. Frequent cycling: If your furnace is turning on and off more frequently than usual, it could be a sign of a problem that needs attention from our technicians. Increased energy bills: A sudden spike in your energy bills could be due to an inefficient furnace that's working harder to maintain the desired temperature. Reduced indoor air quality: If you notice an increase in dust or allergens in your home, it could be due to a dirty or clogged filter or issues with the furnace itself. Pilot light issues: If the pilot light is yellow or flickering, it could indicate a problem with the gas supply or ventilation, which requires attention from our technicians. Aging furnace: If your furnace is more than 10-15 years old, it's a good idea to schedule regular maintenance with Martino HVAC to ensure it's operating efficiently and to catch any potential issues early on. If you notice any of these signs or it's been a year since your last furnace maintenance, contact us to perform a thorough inspection, cleaning, and any necessary repairs. Regular maintenance will help extend the life of your furnace, improve its efficiency, and reduce the risk of unexpected breakdowns.
