What Happens When You Don’t Properly Maintain Your HVAC System

Having a well-running HVAC system can be the difference between having a comfortable home filled with clean air, or an uncomfortable home that can aggravate allergies and spread dust and dirt everywhere. Most HVAC technicians recommend having a bi-annual inspection of your HVAC system twice a year, once in the spring and another in the fall. Many homeowners opt to skip this routine maintenance – why waste the money when things appear to be just fine? But what may appear to be a working system could actually be a system in decline, leading to more money being spent on energy costs than is necessary.

Thermostat on the Fritz

Does your house feel warmer or cooler than normal? Maybe your system isn’t turning on and off the way it should. Regular HVAC maintenance helps to prevent thermostat problems, which can include temperature malfunctions. Not only does this keep your home and family comfortable and happy, it also saves you money by having a system that accurately maintains the proper temperature in the most efficient way possible.


Regular HVAC maintenance helps to ensure that your system is clean, including the coils, filter and blower. What happens when these components aren’t cleaned regularly? Dirt, mold, and mildew build up, and all that gross stuff ends up in your home. Even worse than a dirty home, you end up with an HVAC system that is inefficient, and that can cost you hundreds of dollars a year in the long run. Dirty coils can’t move air of the proper temperature efficiently through your system, and a dirty filter and blower can cause your system to require more energy for air to move through. Because the dirt can build up slowly, you may not even notice the inefficiency of your HVAC system until something major breaks.

Blocks & Leaks

Blocks and leaks are another major problem that can occur if your HVAC system isn’t properly maintained, leading to inefficiency, broken parts, and potentially costly repairs. Many blocks come from a system that hasn’t been properly cleaned, causing problems with air flowing freely through your home, as well as with parts that maintain the temperature of the air. Blocks also have the tendency to cause leaks, leading to air escaping in various parts of the system. All of these issues translate to a less comfortable home and larger energy bills.

Power Problems

Just like any other piece of equipment, components within an HVAC system have a shelf life, including the wiring and power delivering parts that keep your system running smoothly. Bi-annual maintenance checks ensure that these parts are operating as they should – when they fail, it can be a slow process, involving creeping energy bills and a home that just doesn’t maintain its temperature the way it used to. HVAC technicians can also make recommendations about the latest in HVAC advances, so you can find new ways to make your system the very best it can be.
