Most heating and cooling specialists recommend yearly HVAC maintenance to prevent potential problems and help systems reach their maximum lifespans. Even with comprehensive HVAC yearly maintenance, though, problems can still arise and sideline seemingly healthy AC units and furnaces.
Learning what issues require immediate HVAC maintenance is necessary can help you avoid more costly repairs later. Take a closer look at the signs you need to schedule an appointment right away.
Strange Odors
New, unpleasant smells can indicate serious problems. Here are some common odors and what they indicate:
- Skunk or Dead Animal: Possibly a dead animal in the ducts
- Rotten Eggs: Potential gas leak
- Vehicle Exhaust: Burning oil or lubricant
- Musty or Moldy Odors: Likely buildup of mold and mildew
- Paint-Like Smells: Leaking fluids in the AC unit
- Burning Electrical Odors: Shorts, bad circuit boards, or failing motors
Not only can the sources of these smells pose health risks, but they can also mean your HVAC system could fail soon.
Unexplained Noises
Normally, your HVAC system should operate relatively silently. You may notice when the furnace starts up or the AC kicks on, but these noises shouldn’t be jarring. Consider these common sounds and what they can mean:
- Hissing: Ductwork leak, blocked airflow, or high compressor pressure
- Buzzing or Humming: Loose fan motor or other loose parts
- Clicking: Possible electrical control issues
- Squealing: Failing bearings or loose belts
- Banging: Dirty burners in the furnace
- Grinding: Failing compressor
When one part fails, it can lead to the failure of connected parts. If you hear any of these sounds, make sure to schedule HVAC maintenance service immediately.
Poor Heating, Cooling, and Humidity Control
While systems that are over or undersized for a property never heat, cool, or dehumidify spaces well, a system that suddenly stops controlling temperature may have a serious issue. The solution could be as simple as replacing the filter and unblocking some restricted vents. Alternatively, it could be a sign that refrigerant levels are too low.
Such problems could also mean the AC coils need cleaning. This is where HVAC maintenance plans become valuable, as routine inspections and repairs usually catch these issues in advance.
Higher Energy Bills
Well-functioning HVAC systems operate efficiently, which means they control temperature while using the least amount of energy. If your utility bills have suddenly started increasing, your HVAC system may be using more electricity or fuel than it normally does.
Scheduling a maintenance appointment can help you discover the source of the issue and solve it.
Leaks
Puddles forming around your AC unit generally means the condensation line is leaking. If the puddle is refrigerant, however, the problem is more concerning. Leaking liquids is not only a sign of damage but can also lead to further damage. Some leaking liquids, such as refrigerant, can be extremely harmful to you and your family as well.
