What is Furnace Maintenance?

Furnace maintenance involves inspecting all your furnace components for failure. Any built-up debris will be cleaned thoroughly, and all parts will be tested for functionality. An Max’s Fix-it 24/7 technician will then inspect your ventilation system and pilot light to ensure that there are no issues with either and that your home is safe from natural gas or carbon monoxide.

The importance of maintaining your furnace

Your furnace will attract unwanted elements such as debris or other harmful materials such as rust or mold through regular use. Because your furnace affects your air quality, it is essential to clean your ducts to ensure good performance and clean air. Additionally, periodic maintenance will ensure better unit longevity, so you don’t waste money consistently replacing or repairing your heater.

When to consider Furnace Maintenance

So when do you need to consider furnace maintenance? Here are some primary reasons that you should call a professional:

Annual Maintenance and Inspections

Annual maintenance and inspection will provide a good summary on the current health of your furnace. Additionally, you can learn if there are any efficiency issues and how to better address them.

Updating to Higher Efficient Products

New and more advanced models are always available on the market and if your system is older than 10 years, consider a newer model. While it may be initially more expensive, it can drastically save on energy and repair bills in the future.

Smells or Odors From the Furnace

Your furnace is tied to the central air system of your home, so if you notice any odors from your furnace, it may mean the presence of mold and contaminants. Call a professional immediately to inspect your furnace and identify any problems.


Furnaces will eventually grow old and break down over time, leading to poor air quality and a potential fire risk. For the safety of your home, periodic maintenance will help identify when you need to replace your system to prevent any danger in the future.

Improve Air Quality

Your furnace is connected to the airflow system of your home, so maintenance ensures that your filters are clean and no contaminants are being dispersed throughout your home. If you notice a declining quality in your air, inspect your furnace and consult a professional.

Max's Fix-it 24/7 is phenomenal. I have a newer home (8 years) and I was told that both my units needed to be replaced. My neighbor recommended Max's Fix-it 24/7 Heating & Air and Rudy knows how to run a business. I had an issue that was caused by my maintenance man and because I was under the home warranty I was not charged for a visit. I promise no air conditioning is not a pleasant experience with the temperature this hot. My technician, Cody, was actually early, diagosed the issue in about two minutes and checked out everything giving me peace of mind as well. He was courteous, friendly and professional. I felt he gave me a thourough inspection as well. As a former Wendy's Franchisee I have dealt with the trades for over 30 years, please consider Max's Fix-it 24/7 Heating & Air for your HVAC needs.
