Symptoms of an HVAC Unit That Is in Need of Maintenance

Has it been more than a year since you last scheduled HVAC maintenance? If so, then your unit is overdue for this type of service. The following are a few more signs that mean that your heating and air conditioning in Portland require service:

Your HVAC unit makes loud or strange noises.

Although you shouldn’t expect your heating and air conditioning to turn on and run in silence, some sounds can indicate a need for maintenance. If you hear clanking, banging, squealing, or grinding noises when your HVAC system starts up or while it’s running, this means that something inside of the unit isn’t working properly. To address the problem and prevent further damage, contact an HVAC technician right away if you hear loud or strange sounds coming from the system.

You see moisture where it shouldn’t be.

If you can spot puddles or other signs of moisture when looking at the area around the external part of your heating and air conditioning unit, then this could be a symptom of a leak. If the moisture is caused by water, then the unit’s drain tube, which is designed to remove the air conditioner condensation from the system, could be either damaged or blocked. In more serious cases, moisture around the unit could be due to a refrigerant leak. This type of problem can cause issues for the system and pose a health hazard for people and animals. For these reasons, schedule HVAC maintenance if you notice moisture around the unit.

You smell weird odors when your HVAC is running.

A third sign that can indicate something in your HVAC system needs to be fixed are strange or foul smells. Pungent odors can be a sign that the wiring insulation has deteriorated, while musty smells can be a sign that mold is growing inside of the ductwork. If you notice strange or unpleasant odors coming from your vents whenever your HVAC unit switches on, then contact an HVAC service to a schedule heating and air conditioning maintenance visit.
