Heating, ventilation, and air conditioning systems are wonderful devices, aren’t they? They keep us cool in the summer and warm in the winter, tirelessly working in the background without demanding a single word of thanks. But since they’re mechanical devices, they experience the occasional hiccup, leading to diminished service, unpleasant circumstances, or even complete breakdowns. Here are the most common HVAC issues and how to resolve them. Most of the time, basic maintenance ensures your HVAC unit delivers comfort year-round!

Dirty Filters

How often do you check your HVAC system’s filters? If the answer is never, you’re setting yourself up for poor service and, eventually, costly repairs. Filters become clogged with dust, dirt, debris, hair, and more. That’s what they’re supposed to do, of course. But over time, all this can build up, prevent the free flow of air, and damage the system. Whether they’re disposable or permanent, filters require periodic inspection and replacement or cleaning. Check the owner’s manual, or talk to an HVAC technician about the proper schedule for inspection and repair. On average, you should inspect and clean them twice a year.

Thermostat Malfunctions

Keep an eye on your thermostat, even if you can program it and leave it to run your HVAC system unattended. If the heating or cooling seems wonky, check the thermostat. Frequently, a faulty thermostat may just need new batteries or have the incorrect settings. If little adjustments don’t make a difference, call in an HVAC technician to have a look. Something may be wrong with the wiring. Or it may simply be time for an upgrade to a smart thermostat, which will be even more on top of controlling the climate in your home.

Odd Odors

Conditioned air should be hot or cool, but it should never be stinky. Regardless, odd smells have a way of creeping into a mini split or similar HVAC devices at times. The reasons for bad smells vary. It could be that a duct system requires thorough cleaning. Look into hiring a company to blast out the dust and debris in the ductwork. Mini splits may experience clogs in the drainage system, allowing mold or mildew to grow. You can often remedy this by checking the device’s interior for impediments. Burning and acrid smells may occur due to melted wires or failing electrical systems. Less pleasantly, pests can take up residence in HVAC systems and pass away. In most cases, experienced HVAC techs should handle odd odors.

Staying on Top of Things

The best way to combat HVAC issues is by ensuring they can’t happen, and the best way to do that is by conducting regular maintenance. Schedule regular inspections and cleanings. That way, the technician can catch little problems before they turn into big ones. Your tech will look things over, clean out the system, find or prevent refrigerant and conditioned air leaks, and otherwise subject the system to several tests.

Those are the most common HVAC issues and how to resolve them. Hopefully, they’ll help you keep the air flowing and your HVAC system going!
