Every homeowner should already know that regular maintenance of their heating system improves efficiency and prolongs the life of the system. Furnace maintenance in the greater Jacksonville area isn’t just highly recommended; it’s essential for both your physical and financial well being. J&W Heating and Air is here to help!
When money is tight, it makes sense to wonder, “Is furnace maintenance really necessary?” But with roughly a century of experience in the heating and air conditioning world, we know that yes, without a doubt furnace maintenance is necessary. Skipping your annual maintenance might save you a couple of bucks today. But doing so allows your heating system to slowly degrade. Its efficiency will suffer, forcing your energy bills to rise.

Professional, Personalized Furnace Service for greater Jacksonville
With our furnace service, your burners will be pulled and cleaned. To ensure the best possible efficiency, we can adjust your heat-off delay. Our professionally certified HVAC technicians will also provide you with a detailed combustion analysis. This report measures efficiency, allowing us to identify potential issues to reduce energy costs and keep you safe.
But that’s not all!
Our technicians will check the oxygen levels of your furnace and fine tune them for optimal performance. The factory settings for oxygen levels on furnaces are usually a touch too high to provide maximum efficiency. We make sure your furnace’s performance doesn’t suffer from such a simple oversight.
In addition to oxygen levels, we also test carbon monoxide levels. CO affects the performance of your furnace. But more importantly, it can be incredibly dangerous to your health if the levels get too high. Our technicians will measure your CO levels and inspect your furnace for any signs of leaks to ensure your system’s integrity and your family’s safety.
And for customers with older units, we’ll do all we can to extend the life of your furnace and keep it running in peak condition for the remainder of its life. That said, you may want to consider upgrading to a newer, more efficient model. There’s a good chance that doing so could actually save you money in the long run thanks to their reduced energy consumption.
