How To Properly Maintain Your Furnace

One of the best ways to keep your oil furnace working correctly when the temperatures dip is to maintain it throughout the year. Some tasks Mac 5 Services suggests you should perform on the unit regularly are:

  • Schedule a yearly inspection with a furnace contractor in the late spring or early fall.
  • Change the filter at least every three months.
  • Install a carbon monoxide monitor. This should be inspected by a professional during your annual tune-up.
  • Have a heating contractor inspect your furnace ducts to ensure they are sealed properly.
  • Check the blower for any obstructions. If needed, apply lubrication.
  • Inspect the inside of the furnace chamber for defects that could include rust, holes, and separated seams.
  • Clean the burners with fresh water to remove dust and dirt.
  • Clean the sensor and pilot with a wire brush and emery cloth.
  • Check the “high limit” to prevent overheating.
  • Check the gas meter to monitor the rate of fuel usage.
  • Clean the area around the furnace to keep it free from debris.

If you do not feel comfortable with performing any maintenance on your own, our technicians can provide more thorough inspection and tune-ups for you. 

Common Signs Your Furnace Needs Repair

Over time, your gas furnace may begin showing signs of insufficient operation that indicate it needs repairs. Some of those signs include:

  • Irregular or insufficient heating: Insufficient or irregular heating may be a result of clogs in your furnace, a dirty filter, or a malfunction with your home’s thermostat.
  • Unusual noises or odors: If you notice any odd noises or strange odors from your furnace, these may indicate issues with your system’s internal components and potential fire hazards.
  • Frequent cycling: Is your furnace constantly turning on and off? This may indicate major internal issues that increase energy bills and reduce your comfort.
  • Failed pilot light ignition: A failure to ignite the pilot light could be trouble. This likely requires the attention of an experienced HVAC professional to diagnose any problems and determine the needed repairs or replacements.

At some point in the lifespan of your furnace, it may make more sense to replace it rather than continue repairs. Our technicians can advise you on the best route for your home in both the near-term and long-term to help you make an informed decision.

What Could Make My Furnace Stop Working?

There are several reasons your furnace may have stopped working. Some common issues include:

  • Thermostat problems: Trouble maintaining the desired temperature or even turning the furnace on may result from a malfunctioning thermostat. Our experts can diagnose any problems with your thermostat and implement the solution with upfront pricing.
  • Faulty ignition or pilot light: Your furnace won’t ignite if the pilot light or ignition isn’t functioning properly. Leave it to Mac 5 Services to assess any issues.
  • Electrical issues: Faulty or damaged wiring or tripped circuits can disrupt your electrical supply and cause your system to shut down. We’ll locate any electrical issues and swiftly make any needed repairs.
  • Clogged filters: Excess debris or dust can restrict airflow and lead to overheating, which will make your system shut down as a safety mechanism. Mac 5 Services will ensure the cleanliness and open airflow of your furnace so that it operates efficiently.

How Often Should I Have My Furnace Inspected & Repaired?

How often you should have your furnace inspected and repaired can depend on factors such as frequency of use, seasonal climate, etc. However, it’s typically recommended to have an annual inspection to ensure smooth operations through winter.

While you may not need your furnace all year, it’s best to stay one step ahead for the heating season by trusting the licensed and insured HVAC professionals at Mac 5 Services for dependable, same-day service in Brevard County and Melbourne, FL.

Our experience with Joe at MAC5 was above and beyond what we would have expected. We had problems with our plumbing and Joe assessed the issues and provided us with explanations for correcting the problems. Joe was very professional, explained everything in a way that we could understand, answered all of our questions and took great care with everything he did. He is an excellent professional, and I would recommend MAC5 because of the great work that Joe did. This work was done on September 3, 2026 (I am writing this review using my Google email ID, so my actual name doesn't appear).
