12 Signs Your HVAC System Needs Maintenance or Repair
Does Your HVAC System Need Maintenance or
Repair? 12 Signs To Look Out For
SEO Title: 12 signs to determine if your HVAC System needs maintenance or Repair
Meta Descriptions: HVAC systems show telling signs that go unnoticed by most users. These
are 12 signs to know if your HVAC system needs maintenance or repair.
Heating, ventilation, and air conditioning (HVAC) systems have become the backbone of every
home, providing relief from heat and cold. A malfunctioning HVAC system is a big headache for
every homeowner.
These complex systems have a way of revealing inherent faults that go unnoticed by most
homeowners.
This article will highlight the 12 signs that indicate your HVAC system needs maintenance.
1. Poor Airflow
Inadequate airflow from your HVAC system commonly indicates an issue with the filter or air
blower (fan) and can also mean a leak along the duct line. A filter clogged with dust reduces
airflow, which can be solved by cleaning the filters.
A weak blower will reduce airflow and cause the HVAC system to work more, increasing energy
consumption.
2. Gas and Water Leaks
Refrigerant gas in an HVAC system is important for the cooling produced and would cause
issues if insufficient. Though hard to notice except by experienced technicians, refrigerant
leakages reduce the cooling efficiency of your HVAC system.
Water leaks occasionally signal a blocked condensate drain, which can be solved by flushing
the drain line.
3. Strange Noise From the HVAC System
A smooth-working HVAC system is super silent and makes humming sounds. Strange noises
ranging from rattling to squeaking or banging are telling signs your system is due for
maintenance. These noises can mean numerous things and require inspection by a qualified
technician.
4. Rising Energy Bills
Higher energy bills are often associated with HVAC systems, which consume much of a home's
energy. But if you notice a sudden increase in your energy bills with the same frequency of
usage, then it is time to call your technician.
A sudden surge in energy bills could be caused by a faulty motor, leaking air ducts or dirty coils.
All of these reduce the efficiency of your HVAC system and thus increase the energy
consumption.
5. Slow Pick-up Time
A perfectly working HVAC system should respond to changes made on the thermostat in
seconds. When you increase or reduce the temperature from the thermostat control and notice
a delay in the temperature adjustment of the room, then your HVAC system needs to be
checked. It’s probably time for maintenance. The culprit is likely the thermostat.
6. Frequent Repairs
The ideal HVAC unit is designed to go years without issues while maintaining the same
level of efficiency. If your system develops problems repeatedly and requires frequent repairs, it
might be the right time to get a new HVAC system.
7. Frequent Cycling
An HVAC system is designed to go off and on at intervals as it runs. When the desired
temperature in a space is obtained, it goes off and comes on when this temperature drops.
This on-and-off is ‘cycling’ and should not be frequent.
Frequent cycling causes stress to your air conditioning system and can lead to a breakdown.
The main culprits causing frequent cycling are faulty thermostats, bad compressors or oversized
units. This would require a visit from your technician.
8. Low Humidity Takeout
An air conditioning unit is designed to take out hot air and moisture in a space while
simultaneously providing cool air. This creates a balance and ensures cooling occurs fast. If
your room feels damp and humid then the HVAC unit needs to be checked for faults.
9. Blowing Warm Air
This is one easy-to-spot issue with a system. An air conditioning system is meant to provide
cold air but if not then it has to be diagnosed by a technician.
10. Formation of Ice
When you see ice formation on your AC vent or refrigerant pipes then you need to get your
system checked fast. HVAC systems can provide low temperatures of 13 degrees Celsius which
does not cause freezing. So once freezing occurs either at the vents or pipes then it is surely
time for your technician to come check out your system.
11. Lack of Maintenance
It is recommended to schedule routine maintenance sessions with your technician to inspect
and affirm the working conditions of your AC. Waiting for problems to occur before calling your
technicians might be dangerous to your unit.
Routine inspections prevent a sudden breakdown of your system and ensure you spot problems
early. It is recommended to schedule a routine check once in 6 months of continuous.
12. Usage Span
Like any complex machine, your AC has a life span for usage. Your manner of usage and
maintenance practice determines if this lifespan is reduced or extended. For most HVAC
systems, the lifespan ranges between ten to fifteen years.
The frequent visits of your technicians might mean that your system has passed its lifespan and
needs a replacement.
Be Quick
It is important to call for your technician immediately if you notice any of the signs above
as delay can lead to a total breakdown of your HVAC system.
