My AC unit just stopped working. What are recommended CA SEER and code requirements for 2015? I am getting conflicting messages. Our house is 2600 sq ft, 2 story, and had a Lennox HS21 2 stage 5 ton SEER 13.5 AC unit from 2002. Our heater from 1994. One pro said it wasn't worth repairing the leak, and that we should just get a new system and coil - $9500 for a Lennox XC14 SEER 16 5 ton 2 stage. The next pro said it would be $4k to even attempt the search for the leak (all 14lbs of Freon was gone) and repair and recharge the unit. He recommended replacing it with the "required as of Jan 1 2015" SEER 16 Lennox XC14. Oh, and it would be "illegal" for him to replace the AC without also replacing the heater, so the combined cost of AC, coil, heater and all labor/parts would be $15-20k. I can't find anything that says the new code is minimum 16 SEER. I also can't find any rebates for 2015 that apply to AC/Heaters for local or federal/state tax rebates.

My AC unit fan stopped working suddenly. I tested the 3 pole condenser (capacitor) and the it looks OK ( 45 uf , 5 uf is what is mentioned in the spec of capacitor). I tested the resistance in the the wires going to the fan motor and it turn out to be 30 Ohm 50 Ohm and 80 Ohm. ac unit standso there is no open in the motor. what to do with old window ac unitsDoes it mean Motor is fine?ac unit at big lots contractor should be OK (** and i am assuming it **) as it is powering the compressor correctly. What can be the way to debug it further. I can say with reasonable confidence the compressor is OK as i am still getting the cold air at vent also compressor temperature is rising up when the unit is ON. electrical hvac air-conditioning electric-motor

The problem was because the RPM of the new motor was different. So it burned out quickly. Make sure to use the same RPM motor apart from the HP and Amp of the motor. It really makes the difference. the AC guy now installed the same RPM motor and it works great.Browse other questions tagged electrical hvac air-conditioning electric-motor or ask your own question.Does my air conditioning need recharged? It works well until its put on a pull like going up a hill but returns to normal going straight or back down hill...Firestone is recommending a pressure test of over $200.00 and I don't want to pay out that much money if it just needs recharged. Can you help me? they could be right. i dont know why it would need to be recharged if it still works. it would need a recharge if it wasnt very cold any more. (like if it feels that luke warm temp) could be a bad hose. is your cruise set by chance when goin up hills when this occurs? 2 out of 2 people think this is Doesn't sound like it... and a pressure check shouldn't cost $200, find a new shop, they are bending you over their cash register.

When you are on level ground does it blow as cold as it normally would? Does it stay cool at idle(it should get a bit warmer but is it how it normally is?) It loosing cooling while going up hill is kinda odd. Normally that requires a down shift= higher RPMs. It's almost as if the AC clutch is slipping for some reason. Anyone, had a similar issue they can relate to? 1 out of 1 people think this is Ok here is what it sounds like to me. You either have A) Loose connection on a vacuum hose or B) A pinhole leak in a vacuum hose. I have seen a similar issue multiple times and that is what it sounds like with the fact that you are going up hill when this happens but first when you say it stops working you mean it doesnt blow cold correct? I had a van that did the exact same thing. The A/C high pressure switch (also called the A/C cutoff switch) was my problem. The system being overcharged would do the same thing. The high pressure switch is cutting the a/c out because it thinks there is a problem or because there is a problem.

I would have a system pressure check (about $65 at any Midas) and if all is ok then it is your high pressure switch. 4 out of 4 people think this is I have a 99 GC that had a somewhat simular problem. It was found that the vacuum check valve that prevents the AC controls from changing when the engine vacuum drops due to engine operation. The load on the engine as it pulls the hill will cause the vacuum to drop. This check is located on the passenger side of the engine compartment on the fire wall by the AC unit. Under warranty, the mechanic installed a new check valve and placed another check valve in series with the first to prevent the vacuum from bleeding off as the engine was placed under load. Kind of long, but may fix your problem. Mind has been working fine for about 50K miles since. 5 out of 5 people think this is Avoid that garage like they have a social disease. If they tried it once they will try it again. Thank god you got away without incurring any

Pass the word around. Places like that don't belong in business. a check valve or vacuum hose leak. 3 out of 3 people think this is We are approaching Maryland’s hottest months, and keeping cool is a top priority, for safety and comfort. That’s why when your AC in your car stops working, you’ll want to get it fixed as soon as possible. So what should you do if your AC stops working suddenly, or all at once, the answer is to get an appointment with your mechanic, here are some common Car AC issues that make keeping cool hard in the hot weather. One of the most common causes for a failed AC unit or one that slowly stops working is a leak in the system, this causes your cars AC to function with little to no refrigerant fluid/coolant gas. If your car is leaking coolant, do not top it off as a quick fix, leaking coolant is bad for the environment and it is what it is: a quick fix, it won’t last long. Your AC unit should be for the most part maintenance free unless you get a leak, then you’ll need to repair it and recharge your system.

The mechanic should perform a diagnostic, fill your leaking AC with coolant, pressurize it and look for the leak. In certain cases a dye may be used to help locate a tricky leak. Please don’t try to fix a leak yourself, beware of home repair kits, keep in mind if you don’t do it correctly you will release CFC’s into the air. The blower is a component that pushes air through the vents of your vehicle’s heating and air conditioning system, without it functioning the AC unit will not be able to circulate cool air within the car. Over time blowers and their motors can wear out, occasionally when the blower motor goes out your cars computer will display icons alerting you there is a problem. The problem can be as simple as a fuse or a melted relay. Your mechanic can identify if your issue is your blower motor and it is relatively simple to fix. The cars AC Evaporator works to exchange heat within the vehicle’s engine. Most cars have one, but some larger SUVs and Trucks have two.
