Quality Assurance Maintenance
• The Quality Assurance Maintenance (QAM) is responsible for
understanding how and why incidents and errors occur in system
maintenance and support functions, and for instigating remedial
change.
• QAM is also responsible for managing Sentinel, a database of
completed engineering safety reports, which helps to identify
reoccurring errors and failures in practises, procedures and/or
components.
3

Quality Assurance Maintenance
• QAM designs and implements audit programs to monitor actively
all aspects relating to the compliance of regulatory authorities'
requirements.
• It ensures all applicable elements of the quality system are in
place, documented and implemented effectively to ensure that
the corporate commitment and obligations to regulations, safety
policy and quality standards are followed.
4

Introduction to HVAC
• Heating, ventilation, and air conditioning (HVAC)
• It is the technology of indoor and vehicular environmental
comfort.
• Its goal is to provide thermal comfort and acceptable indoor air
quality.
• HVAC system design is a subdiscipline of mechanical engineering,
based on the principles of thermodynamics, fluid
mechanics and heat transfer.
5

Introduction to HVAC
• The HVAC system, like any other installation, requires regular
maintenance and care.
• If you don’t clean and maintain the system, its performance will
start to slip and eventually the entire system will fail.
• This will force you to spend money on heating system
replacement.
• Regular maintenance ensures the HVAC delivers consistent
performance and lasts after a long time.

Importance of maintaining of HVAC System
• Regular maintenance ensures the HVAC delivers consistent
performance and lasts after a long time.
• The HVAC keeps the environment with your property comfortable
and clean.
• The HVAC system filters trap all kinds of dust, debris, germs, and
clean the air.
• They're responsible for maintaining the indoor air quality.
8

Importance of maintaining of HVAC System
• The HVAC keeps the environment with your property comfortable
and clean.
• It ensures all stale air is recycled and helps maintain the indoor
temperature regardless of the hot or cold climate outside.
• As HVAC is such an important aspect of any residential or
commercial building, it’s important to that invest some time and
money in its maintenance.

What is Involved in HVAC Maintenance?
• Inspecting and Changing Filters
• Visual Inspection of the Entire
System
• Cleaning and Removing Debris
• Checking the Condensate Drain
• Checking the Thermostat Settings
• Checking the Electrical Connections
and Voltage
• Lubricating Moving Parts
• Inspecting Exhaust Outlets
• Checking Fuel Lines and Connections
• Checking the Refrigerant Levels

1. Inspecting and Changing Filters
• Filters can get dirty easily, especially if you
live in a location that can be dusty.
• The HVAC system filters trap all kinds of
dust, debris, germs, and clean the air.
• They’re responsible for maintaining the
indoor air quality. If they’re not cleaned and
replaced regularly, your HVAC system will
eventually stop performing as you expect it
to.
• The heating and cooling will be inefficient
and the indoor air quality will worsen.
Inspecting and changing the air filters is one
of the most important aspects of HVAC
maintenance.
11

2. Visual Inspection of the Entire System
• You should get your HVAC system visually
inspected at least once every year to make
sure all the systems are working well.
• This inspection is an important aspect of
HVAC maintenance.
• If you don’t get your system inspected, you
won’t notice a problem until it stops working
in the middle of winter. That’s the last thing
you want because you will have to hunt for
alternative heating sources until the system
is repaired.
• Regular inspection and maintenance also
helps keep it in good shape and prolongs its
life.
12

3. Cleaning and Removing Debris
• Dust and debris don’t just settle in the
filters.
• They can also collect on blowers, moving
parts, condensing units, and other such
important aspects of your HVAC system.
• A light layer of dust is unavoidable but
too must debris can cause a lot of
damage to the HVAC system.
• A professional will carefully clean all the
accumulated dust and debris and make
sure there’s no corrosive damage to the
internal systems.
13

4. Checking the Condensate Drain
• The condensate drain in your air conditioner
and heat pump should be free of all clogs and
debris.
• Clogs can obstruct the flow of condensed
water and cause moisture accumulation within
the system.
• Excess moisture can cause problems like mold,
water damage, high levels of humidity in the
property, uneven temperature regulation,
bacteria, and compromised air quality.
• A professional maintenance technician will
flush and clean the condensate drain to ensure
all excess moisture flows away from the
system.
14

5. Checking the Thermostat Settings
• Most HVAC systems now have programmable
thermostats that allow property owners to
control the temperature and set it on a
schedule.
• For example, you can set the thermostat to
lower the heat when you’re not in home to
save money on the energy bills and ensure the
system isn’t overburdened.
• A professional technician will check the
thermostat during the annual maintenance to
ensure the actual temperature and the
temperature on the thermostat matches. If
there’s a difference in the temperature, the
technician needs to check the thermostat’s
performance or assess the entire HVAC system.
15

6. Checking the Electrical Connections and
Voltage
• Most people don’t realize that the HVAC
connections and systems can come loose
or break over time. That can
compromise the performance of the
system and eventually damage it enough
that you need to invest in furnace
replacement or AC replacement.
• The maintenance technician will
carefully examine the connections and
evaluate the performance of the system.
They’ll look for frayed and damaged
wires and replace them in order to
minimize the risk of fire and component
failure.
16

7. Lubricating Moving Parts
• HVAC systems have moving pasts
in compressors, circulation units, and
furnaces.
• These moving parts need to be
lubricated regularly to minimize friction
and the resultant wear and tear.
• The technicians will carefully clean and
remove all traces of debris from the
moving parts and apply the required
amount of lubricant to control friction.
• This process should be repeated often to
protect the HVAC system from excessive
damage.
17

8. Inspecting Exhaust Outlets
• The exhaust outlets allow all dangerous
gases to escape your property so there’s
no risky buildup of carbon monoxide and
other such gases.
• If the exhaust outlets are clogged, they
can lead to a dangerous build-up and
compromise your safety.
• The technician will assess all of these
aspects of your system and check the
chimney flue and vent stack as well.
They will look for signs of corrosion,
leaks, and back draft and repair the
problem during their maintenance runs.
18

9. Checking Fuel Lines and Connections
• The fuel lines that supply gas to your furnace
should also be inspected regularly.
• Leaking gas and fuel can be a fire hazard.
• Disconnected fuel lines can compromise the
efficiency of the HVAC system as well.
• Soot can accumulate in burners and
cracked heat exchangers can have an impact
on the system’s efficiency as well.
• The maintenance technicians will assess all
of these aspects of the furnace and carefully
and remove all clogs and traces of soot.
19

10. Checking the Refrigerant Levels
• Your air conditioner should have
enough refrigerant in it to cool the
air efficiently.
• If there isn’t enough refrigerant,
the compressor will have to work
harder to achieve the desired level of
temperature.
• That can cause extensive damage to
the system and eventually force you
to replace it.
20

WHEN SHOULD I DO HVAC MAINTENANCE?
• For a system that heats and cools: perform maintenance in the
spring and fall
• For cooling system maintenance only: perform maintenance at
least once a year, before the cooling season
•
For furnace maintenance only: perform maintenance at least
once a year, before the heating season.
21

HVAC Maintenance Tips
• Inspect, Clean, or Change Air Filters Once a Month
• Schedule Seasonal HVAC Maintenance
• Clear the area around your HVAC system
• Clean Evaporator and Condenser Coils (once or twice a year)
• Maximize Air Flow
• Install a Programmable Thermostat
22
