If you’re not an HVAC expert, it can be hard to know how to address common HVAC issues. Today, we’ll go over some common issues and how to fix them. For those HVAC services where you need a professional, contact our team at Davis Heating & Cooling in Flemington! 

Dirty or Clogged Filter

Did you notice that you have a dirty or clogged filter? Or did you notice that the airflow from your vents has gone down? Some HVAC problems can be solved by replacing your filter with a new one! Your unit pushes air through the filter, so if that filter is not clean, your entire system will strain. We recommend changing your filter every three to six months in order to ensure proper airflow throughout your home. 

Thermostat Malfunction

Do you remember the last time you replaced your thermostat? Are you still using the original thermostat? Some problems with your HVAC system could be a result of an outdated or old thermostat. That’s because your thermostat controls your HVAC needs throughout your home. 

If you want to take a look at your thermostat yourself, check for dust (or even a dead battery). But if your HVAC isn’t properly heating or cooling your home, you might just need to replace your thermostat. Just give one of our technicians a call and we’ll get you set up with a new thermostat! 

AC Not Cooling Enough

When it comes to your AC, you never want warm air blowing out of your vents. This could be a sign that your unit doesn’t have the right amount of refrigerant to properly cool that air. If that’s the problem, that means that your unit probably has a leak. When this happens, it’s time to schedule an appointment with an experienced technician to make any necessary repairs. 


You never want to see moisture around your HVAC system. But if you see moisture on your system, there’s a good chance that there is a leak on your unit. Inspect your unit for signs of a leak or  water pooling around your unit. If you find any moisture, make sure you schedule an HVAC service technician to come out and make any repairs!
