Most of us have experienced a winter cold or flu. You usually feel it coming on by noticing familiar symptoms. This often happens at the most inconvenient time, so we start treating the symptoms right away in effort to keep them from worsening.

Just like people, our HVAC systems can get “sick,” too. Recognizing the symptoms and making sure they are “treated” quickly can help avoid a total breakdown, which is never convenient! Here are some symptoms that may indicate an appointment with an HVAC healthcare professional is needed for your system.


If your thermostat’s temperature seems to be wrong—like turning it higher than normal but not feeling any warmer in the house, or if your unit keeps cycling on and off without reaching a comfortable temperature, issues such as faulty wiring or inaccurate calibration could be the cause.


Cold spots in certain rooms of your home can signal blockages or leaks in ductwork. It might also indicate a problem with the fan or fan motor.

Unusual Noises

Much like coughing or sneezing noises from people, noises from your unit—running louder than usual, banging, buzzing or other unexplainable sounds—can indicate your system is coming down with something.

Sluggish Symptoms

When you get sick, you may feel sluggish as your body isn’t running as efficiently as normal. Your HVAC system may become sluggish and run less efficiently when it’s sick, too. Longer running times, more frequent cycling on and off, and higher than normal energy consumption (keeping the colder weather in mind) could be signs you may need to schedule a housecall for your unit.

Preventative Care and Treatment Options

Preventative care is important in caring for your heating and cooling system’s health. Changing your filters regularly and scheduling maintenance checkups for your unit can prolong the lifespan of your system. GVEC Home® offers Comfort Check plans to help keep your unit in good condition.
