Rheem Ruud heat pump(s)

are the easiest to repair and service.

because the compressor and control panel

is located in a box.

Of all the heat pumps that I have worked on I have found Rheem Ruud to be the best to service. Unlike Carrier, York, Intertherm, Trane and others the controls can be gotten to by taking out two screws on the top.  If A fan motor needs to be changed they are equally easy to work on too. I am not saying that Rheem/Ruud will work any better but it easy to change a compressor.

    I have seem a lot of problems with Rheem/Ruud heat pumps that use a capillary system on the indoor coils where the coils will clog up and render the unit unusable. Please see the "ice" page for details and how to fix it.

    The absolute quietest unit I have ever seen in my life is a super efficient Rheem/Ruud unit that is 2. 3 ton units placed together with the compressor and other components in the center. The compressor is inside an insulated sheet metal box that preserved the tubing so it looked like it was factory new. The compressor had failed and we replaced it. When we were done the only way you could tell the unit was running would be to put pressure gauges on it. The fans were 850 rpm motors with a shallow pitch like 27 degrees. I mean this thing is quiet. It is also super efficient too since it has a 3 ton compressor with a 3.5 ton indoor section and as I described an immense outdoor coil. I would rate this unit in my top ten best. I wonder if it is still made? I advised the customer to never get rid of it if possible even though it is 20 years old.


    There is a rumor or myth that after so many years of service (like 5 or 10) a heat pump must be replaced especially if it is icing. The fact is that properly maintained a heat-pump will last for many years even 30 or more especially Trane.

    We have seen many cases where a system is leaking refrigerant 22 for many years and the leak is obvious and can be fixed easily instead of adding refrigerant constantly.

    We have seen situations were several different companies will simply keep adding refrigerant and charging the customer for it until the compressor is ruined. Contrary to popular belief an air conditioner only needs the correct amount of freon 22; adding more will make the system work harder and not cool as well.

  If your unit turns to a block of ice in the heating mode please read this.


Why heat pumps get a bad reputation

    Many of you who have heat pumps and those of you who have heard of them or considered adding one have heard all the bad things about them.
    While I prefer other means of heating especially radiant flooring I must contend that they are a good way to heat in certain situations.
 Lets address your concerns with this list of heat pump problems.

Reason 1: Gas and oil systems are usually sized larger than they need to be and as a result one gets used to having instant heat or at least having the house warm in a hurry.

Reason 2: If you push the thermostat up to get the house warm in a hurry you will usually cause the electric heat to come on and raise your electric bill.

Reason 3: Heat pumps are usually sized for cooling (for good dehumidification) and the heat is made up my electric resistance heat which is expensive. If heat pumps had two speed compressors and were sized for twice the cooling need then this would be less of a problem.

Reason 4: Heat-pumps loose their effectiveness  (not to be confused with efficiency) the colder it gets outside forcing you to either use the electric heat or stay cold. This is why ground source or geothermal systems work well.

Reason 5: System that are designed poorly the duct work is too small resulting in a lot of air noise and drafts of air that is not a warm as one would be used to on a gas or oil system.

Reason 6: Bad media campaigns have convinced homeowners that they don't work when they actually do quite well especially against propane or oil heat. Keep in mind that each fuel source has their lobbies.

Reason 7: If you have oil or gas forced air you may think that there is something wrong with your heat pump unit because the temperature of the discharge air is not as warm.

Reason 8: If the defrost circuit is not working right when the unit goes into a defrost to prevent icing you may get a blast of cold air thinking it is normal but it can be corrected.

    If you have propane or oil forced air or hot water consider adding a heat pump as a back up or primary system to save money or hold you out in case you run out of fuel. if you have us install your fossil fuel kit I can rig controls so if you run out of oil or propane you can be automatically switched over to heatpump operation so your house won't freeze. The kits I have seen especially Rheem Ruud don't have a provision to detect loss of fuel.
