Hi,

We have a central air unit, and I was wondering if it is excessive to have
the condensor taken out and cleaned once every other year.

It's a Payne natural gas unit, (GB1AAV036065) with a blue plastic?
cleanable
filter. They replaced the blue plastic filter with a fiberglass blue
filter.
It fits poorly.

The two air vents do not have filters. I was thinking that air is getting
sucked in and clogging the condenser unit? Is this excessive?

Also, sometimes when the is igniting, it sounds like the gas is on, but it
fails to ignite? Or it sounds like it does ignite but the unit fails to
notice it's ignited? It happens about once in every 4 cycles.

It has been cleaned before because it would not heat. It would try to
ignite
3 times and then just stop.

Just wondering if changing the vent opening and putting in a filtering
vent
would help it out.

Thansk guys. I appreciate it .

The coil in the furnace is the evaporator, is that what you are wanting to
clean? I have seen evaps so filthy that no air could get thru, but this was
in a case where the furnace was run for many months without a filter, and
the folks had multiple cats, dogs etc. that will plug one up pretty fast.
You can remove the blower on most furnaces and look up thru the heat
exchanger slots and see the evap. If it looks crudded up, can't see the
fins, etc. then a cleaning is in order. I have used a CO2 fire extingusher
on the output side to blow debris backwards thru the evap, but I can't vouch
for how well this will work for you. Actually pulling the evap and cleaning
it is a very expensive proposition, as you would have to cut lines, pull out
the freon, then pump back down, recharge etc etc.
Good luck,
Tom
