Having problems with your Air Conditioners ?

I had two very different quotes for installation. They recommended different models and different blowers. 15k vs 17k mxz4a36na vs mxz3a30 model. By getting the less expensive model and smaller blower am I going to be with less power and/or higher electric bill to run?

Answers :

The last two numbers in the model number indicates the Btu ratings. The mxz4a36 indicates that this unit is capable of putting out 36,000 Btus and only 30,000 Btus on the other. I would be concerned that the second unit is large enough to satisfy your cooling load. Forget the power, make sure the unit is sized properly.

On the 22nd Sept.2010 I received my replacement remote for Model RAS-09CHA1R/RAC-09CHA1 A/C The price with GST & PP was almost $200.This is the only Hitachi A/C I have. My other A/C remote cost about $39 for a different A/C manufacturer. I find this extremely expensive and 1/3 of the cost of the Hitachi A/C.If the replacement costs are going to be this expensive I would be most reluctant to ever purchase another Hitachi product. Would you please explain the reason for this exorbitant price.

With unit set to air conditioning, the controller board will not turn on the blower motor and the cooling coil freezes up. McNutt tells me the controller board is kaput and they want $550 for it. In the meantime they have jumpered over the controller so the blower runs constantly. Was hoping someone might be able to tell me where to get it for less. It is HSCI Furnace Controller For Use With All Gasses 1012-940, model HK42FZ011

Hello, I have a Amana Air Command 80 model #GHI90A50, 22 years old. This furnace is on its third ingnition module (last one two yeras ago).

The sequence is as follows: Cycle start (small blower turns on), followed by the ignition module illuminating (yellow) for 3 seconds then turns g

Short Cycle I have an Intertherm Model 497580 in a manufactured home. It continually short cycles. The blower will cut on and cut off about every 2 mins. I have had two different "professional" HVAC people come out and it still does the same thing. One replaced what I think was a relay. Small round black disk with two wired. That was $138.00. The other came (twice) and check Tstat adjusted something on it. That was $50.00. It does seem to run longer if the grate and filters are off and

Model TWEO36C140A1 blower will come on if I throw the breaker switch...but thermostat doesn't seem to be in sync. Fan will run in "on" position and once blower is running, in auto. Blower ran for quite awhile, a couple of days, until I touched thermostat as we were roasting. I knew that would be a mistake! This morning, blower won't run when I switch breaker back on even after letting the motor cool for several hours. Is there a relay switch somewhere? I don't see it. Or does thi

I have an old RUUD central AC unit that started blowing hot air. I set the thermostat to off and set the temp gage higher than air temp to turn the unit off and save money, but inside blower unit runs constantly. I'm trying to save money to have it serviced, but noticed my electric bill was higher that last month when the ac was working. The bill was about 4 times higher than the winter when ac is off and the gas heat kicks in. Can the blower running constantly cause this power usage and what is

Just installed new Goodman 95% updraft furnace with 3" supply and vent lines going out through wall. Gas valve won't open. Circulation blower runs in manual on, A/C system runs fine. I have used an ohmmeter and voltmeter to do checks. The entire series of safety switches are closed. When the small blower is running, both pressure switches close. The igniter comes on but there is no voltage to the gas valve. Just after the igniter goes off, I hear a relay click, the circulation blower seems

Make sure you have bled your gas lines. If any air is in the lines, it will cause the unit to do exactly what yours is doing. The relay "click" you hear is the gas valve opening, but if there is no gas, it will not ignite. This is common for a new in ... Goodman Air Conditioners

My 8 yr old Amana heat pump, model RHE48A2D with Honeywell progammable thermostat in heat mode has the blower running constantly. When there is a 6 to 8 degree differnce between room temp and thermostat setting compressor runs as it should, the closer it gets to thermostat setting, it will run about 30 seconds, blower continues to run until getting just cool air, about 5 minutes, compressor kicks back on for 30 sec., continues to do this, thermostat shows it has reached set temperature,

Hi, I have Lennox gas furnace Model G12Q3E-82 (about 30 yrs. old). When running the A/C, I noticed there was water leaking or dampness around the bottom of the furnace. I removed the hose from the drain spout on the evaporator and noticed it was plugged and unplugged it to drain some water out of it. I also removed some water that accumulated in the bottom of the frame that wraps around the blower motor and fan wheel. I have a problem where now the blower motor runs for about 1 to 2 minutes then

My compressor unit outside runs and cools Freon but the inside blower has a problem running. the model # is 2TEE3F31A1000AA. The fan control, in fan run control mode, shows a bright green for the fan LED and the CFM selection LED varies with the rotational speed of the fan. The motor tries to start showing , initially, a jerky back & forth movement. It squeaks some and may, or may not, start rotating. If it starts the CFM LED goes bright/on no flicker and the motor runs briefly (5 seconds) then

Have six year old Bryant electric furnace with heat pump, no gas. Old blower motor was going out and replaced with another generic blower motor. Wired the new just like the old and changed capacitor. There are some differences between old and new. Old says "Volts 208-230" and new says "Volts 115." Problem is blower turns on and of, over and over again. Help?!?

I have a Arcoaire Gas Furnace (Model# GNJ100N12A1), that will not fire up. It has a White Rogers Digital Stat. First the Stat seems to be faulty, since it reads 70plus in a house that has a temp of 30 or below. I can adjust the Stat and the blower motor will run. The rollouts (3) were reset; the inducer fan would run; then the unit would cycle and shut off. Now the inducer won't run. The ignitor is good, but would never glow. A friend tested the current coming from the Stat, and found 24

The model number as listed on the receipt is CKQ24. The Blower moter in the air-handler is not running. When the fan-only switch is turned on, the blower motor will attempt to spin by pulsing for about 2 seconds. It will repeat the pulsing cycle in about 2 second intervals. There is no smell of burning. When the unit is set to AC and auto, the evaparator coils do chill. The blower motor is a variable speed motor with an external ECM. How do I test the ECM and/or motor? What should I look for in

I have this model of air conditioner and it shuts off from time to time. It will run for a while and then power down. Then when you try to restart it will run for a few mins and shut down again. But I tried it in a different out let and it will run for a longer period of time. It is not tripping the breaker on any outlets. Is this an issue with the compressor getting over work and it shutting down to cool off?
