Corrosion Our unit is only two years old & is suffering from corrosion according to the service man.  My wife uses a lot of vinegar in the house to clean and wash clothes as she has allergies to all regular household products.  Could there be a connection between the two?

I have found this in some industrial shops that I work on the air cons at. That the acid in the air does actually eat away the coil. Althou she would have to be using alot to eat away the coil in two years. I would get hold of a warranty agent and see if they could get a second opinion.

If they give you the same story get a coil cote to protect the coil or your unit wont be lasting much longer. I am in australia and use a product called Kirby Kote that is about 40aus and works a treat.

My wife and I just purchased a home built in 1900. It has two separate HVAC systems, with a package unit downstairs, and a traditional compressor/furnace combo in the upper. Most of the windows are in need...

With that large of an opening I would inspect the blower and as much inside the unit as I could get to as there is no telling what might have gotten in there and is obstructing air flow. I would remove squirrel cage and blowere motor and clean thourghly,clean burners and exhaust as best you can.
In thirty years in hvac and plumbing you wouldn't believe some of the things i've found in furnaces and ductwork. Cleaning and serviceing the blower motor should help.
Best of luck to you and your wife and hope this helps you. Thanks

Hi..we have switched on AC yesterday night after 3months. Water started to drip from the front. What could be the reason and fix to the problem?

Clogged drain condensation drain pipe. They use to recommend white vinegar for cleaning, but they now say even it can damage lines for being to strong. The sell a product Zest at home depot, it's like orange and environmentally safe made with oranges or something.

Anyways use that stuff.
I would first check the outside pipe for an obvious blockage like grass, dirt or dead animal. Then right by your indoor unit will be the start of the same pipe, if the leaking is there, then that's it, if it's somewhere else could be in the unit which you will need a repair man, nothing easy inside the main unit except lots of shocking things.

Open the pipe inside and try pooring some cleaner in , wait a bit then turn back on and see. If it's a bad clog, what I did was to take a long hose, run it in the house to the pipe. I put folds in the hose to do it alone, or have someone outside to yell to turn it on. Put the hose against the pipe inside flush as possible and that should force almost anything out. Be sure to have a couple towels ready cause it's nearly impossible to not spill some water doing it this way.

Every 1 minute it has a one second surge

Hello Dave,
The first place to start is with the line voltage supplying the condensing unit. Check ALL line voltage connections at the condensing unit, the service disconnect, and the electrical panel box. If you have a weak connection or overheating circuit breaker, it could create these surges.

Don't forget to ensure the filters and coils are clean to keep your system operating at peak performance & efficiency. :-)

We have RUUD AC, in second floor , that has a white pvc ope connected to condensate drain. other end of this pipe is inerted into large pipe neanr wall. looks a drain outlet. In the middle of this white...

Hello, W/D here.

There are a couple of things you need to check:
Look at where the drain connects to the A/C unit. There should be another pvc line right next to where the drain connects. This is the clean out/flush line, and is used for adding algeside to the tray internally, which thens go out the drain. Most importantly, there is a 1/8" hole between them, and usually, it's very hard to see. Make sure that this hole is open. If it is plugged, the condensate cannot drain from the unit while the unit is running and will create havoc with your drain system. The 'tee in the drain line is an air vent/vacuum breaker and can be used for a cleanout, but try the little vent hole trick first. Your drain line from the unit should be sloped to your house drain. If you do not have a clean out connection at your unit, then you can clean from the tee to the wall. Put one cup of white vinegar into the tee. It will work as well as bleach, without the corrosiveness of the bleach. If you have a cleanout on the unit, put the vinegar in there, and restart the unit, as the vinegar needs to get flushed by the condensate.
Your tray is designed to catch any leakage, and should drain to the outside. Look for your drain line and clear it. Tray drains generally plug at the ends, and not usually in the middle. You can clean the pan drain with a piece of stiff wire. I like to use electrical solid core wire, #12. Pass it dowh the drain from the pan, and back up the drain from the outside. Chase it with water. Usually the pluggage is either insulation, or dirt dobbers.
Best wishes and regards, W/D

I have a Goodman CPH 30-1fb heat pump... 3 days ago, unit was running fine @ 11 in the a.m. holding a 78 set at thermostat in 93 degree weather, I came home at 8 p.m. and thermostat showed 86 degrees in 89...

I always tell my clients that if the repair is more than half of the cost of a new system then they should consider their options..according to the DOE ( the average life of a standard air to air unit is about 12 years. Note.. there are only two things that cvouse a unit to freeze up.. low charge (leak or undercharge) and lack of air flow, (usually maintenance related) The temperature that is usually seen with a correctly operating unit is between 50-55 degrees at the closest supply register. You may also want to consider the fact that R-22 is being mandated into obsolecense, I would consider an upgrade to a new system with the new refirgerant (R-410a) before spending another $300 or more on a 15 year old unit. as far as brands... there are only a couple of places that make compressors, fan motrs, contactors and the componenets that are required to "build a unit" what you are buying when you buy a brand of a/c is the warranty, the service after the sale by the dealer, and the factory backing for the dealer, also what color and shape is the unit... verify the contractors BBB rating, ask friends for referrals, and verify what the warranty covers...(in writing!!) Hope this helps

Amana Air Command 80, 20 years old. Electronic ignition. Furnace does not start. Good power to furnace. Themostat properly set. Where do I start looking? Bob

Hello Bob,
Welcome to fixya,

You said, Amana Air Command 80, 20 years old.
Electronic ignition.
Furnace does not start.
Good power to furnace.
Thermostat properly set.
Where do I start looking?

Sounds like you possibly have one or more bad jets if the unit is a gas furnace!
Let me know how it goes.

WOW, listen to this story!
I understand you are looking for the solution to fix your furnace your self.
But I want to tell you my story about my smart wife and our furnace.
When we moved into this house the furnace was 20 years old and she suggested that we put a new one that it will save us money.
I laughed at her and replied if it's not broken why fix it!
Six years later it finally broke down and I replaced the whole furnace and central air unit with a new one.
Our utility bill went down $100 dollars a month!
That's $7200. that I lost over 6 years due to not respecting my wife's power of reasoning!
If you can afford it or can get financing replace any unit 20 years old and it will pay for it self.
Can you imaging $1200. a year for 20 years is $24,000 dollars I'm saving with a new and efficient unit.
Do the math!!!!!!!!!

Thank You,
Huuum, Hope I gave you some good fatherly advice.
Please remember to leave a rating
