The notes.
Section 1: Its Almost Summer!
The Heat Is Coming- Puts the fear into everyone!! Plan ahead now before it gets
hot. Landlord discussions etc.
AC’s are Weird- Can’t see much of the equipment but they are crucial. Nightmare
when they break down.
Recent Arrivals- Many people don’t have experience of AC’s in their home
countries. Some trepidation about them.
Technicians Arrive & Disappear Onto the Roof- No real idea about what they do & then the bill is
presented!
How Do You Work Out What You Need & What A Good Supplier
Looks Like?- Do they warranty their
work? Are their technicians qualified? Has the supplier been around for a
decent amount of time? Internet? Friends recommendations?
Section 2: Types of AC Within Dubai Homes & Work
Required
Chilled Water vs Split Gas- Usually split based on property type
Modern Apartment- chilled water
Villa- Split gas. Variations- Multi-systems, Package Units
Anomalies- Chilled villa’s- Green Communities, Jumeirah Islands,
villa complexes attached to residential towers- Mainly Marina. Gas Split
Apartments- Older apartments e.g. Satwa, Deira, Karama & International
City
Types of AC Maintenance Work Required (Gas Split):
AC Service-
Regular mechanical cleaning & checking that should be undertaken 2-3
times per year. Should take 30-45mins per unit.
Cleaning- Indoor
filters- All rubbish companies do. This is not a service!!, condenser coils- on
the roof, drain pan (disinfect), vents
Electrical & Mechanical Checks- Indoor fan motor, outdoor fan motor, compressor, power cable
& isolator, thermostat
It Needs More Gas!- Standard Dubai customer call! Rarely the case. Standard 65psi
(double a car tyre!). Only loses gas if a hardware defect. More gas= short-term
fix.
Service Review- Noise- fan housing, fan motors, Condition of insulation,
temperature of air coming out of the vents, coils & ducts, balanced air
flows
Duct Cleaning- Mechanical & chemical cleaning of the ducts leading from
the indoor AC unit to the vents. Once every 2 years
Equipment- Specialist
kit! Rotobrush vs negative air.
Rotobrush Process- Mechanical- Rotating brush with integrated vacuum. Chemical-
Fogging. Camera- Can be used to verify.
Coil Cleaning- Evaporator coil (indoor unit) cleaning. Really difficult but
massive benefits! 3-4hrs per unit
Traditional Method- ‘Open Heart Surgery’- Remove drain pan, fan
motor, cut out the coil, take outside, power wash with chemicals, WELD
BACK IN!!!, re-install all components, re-gas & test.
Our Method- ‘Keyhole
Surgery’- Adapted US Equipment designed for another purpose which allows us to
clean the coil without removing it from the unit. Scene from Crime Scene
Investigators (CSI). Faster, safer, better value.
Cheating- Ash on
coil raked with a comb brush- Only cleans (poorly) exterior of coil. Can’t
reach behind coil. Very poor!
PART 4
I have put down some
artificial timber tiles on my deck outside in the garden. Unfortunately they
have lots of white leaching going on and doesn't look very attractive. I was
wondering if there is a particular varnish or sealant that I could paint them with
so that they look nice like when they are wet but on a permanent basis thanks

Why do we even have water
tanks? Don't have in europe. Luke
Good evening gentlemen. Doc James my philosophy is
"If it ain't broke don't fix it, if it's broke don't try to fix it
yourself, call the professionals ". Sam
How easy is it to instal something to protect wall corners from
kids and chipping in heavy traffic areas?
Any garborators being used in the UAE?
The kitchen fume hood can it be easily ducted out of the
apartment?
Hand rail is loose at the base it is going into concrete
what do I need to do to secure it?
