Warning Signs to Call an Emergency HVAC Professional
While property owners may neglect minor issues, there are a few vital signs that the HVAC system requires immediate attention
Taking good care of the HVAC system is part of essential homeowner maintenance. However, while property owners may neglect minor issues, there are a few vital signs that the HVAC system requires immediate attention. This article shares some of the most urgent ones.
Unusual noises
Knocking, gurgling, or banging noises from HVAC units may indicate a severe issue. For example, an element could be stuck inside, or there could be a problem with the device’s hardware.
Warm air coming off the vents
AC units that blow hot or warm air from the vents need immediate attention from HVAC professionals. For example, there could be a faulty compressor or blockage that needs to be removed for the unit to blow out cold air again.
Too much humidity in the home
HVAC systems help reduce humidity inside a house. However, increased humidity levels can signal that the unit needs some repairing.
The ideal humidity levels are around 40%. Higher levels can encourage mold and mildew growth or make the atmosphere stuffy.
Broken outdoor fan
A properly working outdoor fan spins whenever the AC unit is on. It takes the hot air from the interior and releases it outside. A non-spinning fan is an emergency sign and requires immediate attention. Otherwise, the entire unit can overheat, which can cause significant damage.
Bad smells
The HVAC unit shouldn’t release odd smells. Homeowners who notice a weird smell from the unit should contact professional HVAC technicians and turn off the unit immediately.
A smell that resembles burnt plastic may indicate a ductwork issue. Chances are, the system needs a good cleaning. Repairs or replacements are sometimes necessary if the problem goes undetected for some time.
Wet carpets
Many homeowners realize they have an HVAC emergency when the carpet under the unit starts getting wet. Leaky units indicate irregular or malfunctioning drainage systems. The cause can be clogged drains or improperly installed AC units.
Low airflow
Slower airflow through the vents can indicate air duct blockage. However, it can also mean a motor issue. Either way, it’s a good idea to contact professional HVAC technicians to determine the cause of the problem and quickly fix it to avoid further issues.
Visible ice on the unit
If the HVAC system starts to ice over, it’s a good sign that the evaporator coils aren’t working correctly. Homeowners can double-check for ice formations on the outdoor compressor. These formations can happen because of a clogged filter, grime, or a leak. Any ice formations on the unit warrant a call to an HVAC professional. They can diagnose the issue and address it adequately.
Tripped breaker
An air conditioner that keeps tripping the home circuit breaker can indicate an electrical problem. Such issues can damage the AC unit and represent a significant fire hazard, so homeowners must call an HVAC professional immediately to repair the problem.
Don’t wait to call a professional for HVAC emergencies
Fixing HVAC issues can be rather tricky. Homeowners who lack tools and experience should refrain from performing DIY repairs, especially if any of the abovementioned problems arise. Instead, contact local HVAC professionals for a safe, secure, and long-lasting fix to the problem.
