Question about Heating & Cooling

1 Answer

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 degree weather... I shut it off and spent all sunday morning crawling under the house, opened air handler and as I suspected evap coils were still thawing out from ice, I removed all ice, cleaned coils with Frost King solution, dried and cleaned it out, blower was clean and unobstructed, turned unit back on and it worked like a charm, pumping out 62 degree air in with a full blast, the most I've ever felt. It did, however take 9 hours to go from 86 to 79... Today in 95 degree weather, the unit is still holding a 79 @ thermostat, but I check the suction line and see ice... I 'm feeling the end of the line for my unit... My question, is it worth the 300 bucks it will take for the local techs to find and fix leak/ recharge and clean condensor coils or should I just pump freon in and save up to purchase a new unit next spring... I do love the cold and so does my wife... usually keep windows open during winter... Or, is this 15 year old unit salvegeable? Paid 300 bucks last year for same service and the tech found a small leak on condensor tubing, other than that... seems to work o.k. If I do get a new system , which brand would anyone recommend other than Goodman?

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 (doe.gov) 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

I am working on a M # GPG13420901AB. This is a 3.5 ton package unit that replaced a 3 ton package unit on 1700sq/ft single level home. Old unit was working fine but was replaced when the home was...


It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.

New Goodman condenser unit run almost contiously using too much e


I'm not sure of the kilowatts. The 10 min on and 5 off is telling me there is to much heat by the thermostat or you house needs more insulation. The new compressor is designed for more efficient run time. The other thing is the unit to big for your house? It should run 10 -15 min when low humidity is in the house. Otherwise longer if its pretty warm inside.

Electric furnace runs but won't shut off on heat setting


I would insist that Sears either have a Senior tech come out and fix it or return it to the state it was prior to them touching. Then call some one else. Have them involve the Goodman rep in your area.

Replacing TSTAT for my Goodmans 3 ton heat pump. Only question I have is optimal setting for AUX heat CPH .. I think 5 or 6. ????


5 will be the most economical CPH means cycles per hour . So the thermostat will only let the heat strips come on 5 times a hour. You should not need the aux heat except on the coldest days.

Heat pump auxiliary heat does not turn on


Turn up your outside thermostat in the outside unit.
You should have about 3 degrees difference in one stage to the next. So I would change the thermosat with one that has three stages of heat.

Goodman a/c works, heater will work fine then fan will stop


you have a circuit board acting up. Try keeping the fan in the "On" position. It will keep the blower on all the time but it may work. There is a built-in delay not allowing the unit to come on after you reset it with the thermostat, wait three minutes or so to see if it comes back on. I still suspect a bad circuit board.
