Central Air needs to be cleaned every other year?
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 |

Condenser coil is the coil on the outside of the house and can be washed out every year with a water hose and does not need removing at all to clean. The evaperator coil should not have to be removed and cleaned unless you are a very poor filter keeper upper . If you keep a good clean filter in it you should never have to pull it and clean it , but after about 20 to 25 year of use i might say pull it to clean it. Whay you have decribed on the furnace is a False start and you might have furnace service come check it out for it should not False start at all. TURTLE |

i meant the evaporator coil has been cleaned because the water wasnt
draining? wasnt going to touch it just wanted to know if it needed a filter where the incoming air vent is (there are two) and it has a filter where the blower is but i was thinking it wasnt good enough. the filter gets changed every 3 months thanks |

Any Cheap filter will keep the coil clean enough to not have to clean it. The Drain stopping up is caused by Fungues and not dirt. It is the same type fungues that grows in a swimming pool to clog it up. The stuff in the evaperator coil is white due to no sun lite and the swimming pool stuff will be green because of having sun lite to make it green. TURTLE |

The condensor is t hat which condenses (liquifies) something. The condensor
is already "out", it should be outside the house. The part th at gets cold is the evaporator. Now, I've known central AC that ru n for 10 plus years with the evaporator still in place. If it has to be cleaned that often, you have major problems with your air filtration. As for the ignition problems, it's time to call a heating repair co to fix that for you. -- Christopher A.
