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.
