How Hard Is It to Add a Heat Pump to Central Air and How Much Does It Cost?

You need a lot more information to determine cost. You need to add an outdoor condensing unit, an indoor coil, inter-connecting refrigeration piping and control and power wiring. The difficulty of installation, size of unit, availability of power, cost of labor in your area will all greatly effect the price. Call a couple of local contractors. They give free estimates. If they do not do a load calculation to determine the unit size beware. They are just guessing

1. Why do people think gun control works?

Man, Ignorance is bliss, And they are a bunch of happy *******. (It's a case of media-perpetuated liberal stupidity.) Gun control is not about GUNS It's about CONTROL. The Left wants to CONTROL every aspect of your life. Historically this has been difficult to accomplish when the citizenry have legally owned weapons. In 1936 a power-hungry control-freak instituted the first modern gun-control legislation. In GERMANY. His name was HITLER. (The U.S. gun control act of 1968,(the GCA 68) is almost a verbatim translation of Hitler's gun control act of 1936. LOOK IT UP!) Tens of thousands of Americans die due to automobiles every year in America. Far more than die from being shot. They die Accidently, and on purpose, just like with guns. But you never hear the leftists crying for "car control"..... Hitler's GCA did not reduce crimes commited by German citizens. It instead ALLOWED a crime to be perpetrated UPON German citizens. And German Jews, And Polish citizens, And Russian citizens, And Lithuanian citizens, And French citizens, And Dutch citizens, etc. Allowing abuse of government power with no fear of reprisal from the people is what gun control is REALLY about.

2. What kind of return would I get if I installed a heated tile floor system?

Depends on the heating system your considering. If you have a boiler or hot water system now and can tie into it for a reasonable cost, Then it s a good selling point and you won t get a big return just a good return since its in the kitchen. Putting in a hot water system just for a tile floor wouldn t be cost effective on the return. For a long term investment for your personal use, thats different. If your planning a electric heat system they draw a lot of power foe a larger area and the heating mat and control can be expensive and I m guessing it won t be a good selling point because of the electrical part.

3. Advantages and disadvantages of buying one of these 3 dogs?

Based on what are the three breeds suitable? You say that presumably from scratching the surface of the three breeds listed, they are on the shortlist because of suitability, yet the question suggests you do not know even the basic information about them. To answer your question on the Doberman: It is NOT born with a naturally protective gene that strengthens as the dog matures. Unless working bred and pro trained it will look out for its own safety if the owner does not and not react defensively to protect human life. A strong watch dog instinct yes, the breed typically comes into its voice at puberty, but signaling when someone approaches the property is ALL that should be realistically expected from an untrained pet dog. It is a breed that NEEDS at active household that will provide an adult with a minimum of 2 hours daily exercise off the property. Scores high in trainability, intense focus and driven nature and willingness to work in partnership with its owner to achieve their goals, but for that to happen an owner must show the leadership qualities a dog needs to see in everything they do with it and possess natural quiet calm confident authority. Yelling or using the physical strength to break a dog's will not natural strength of personality and assertiveness will not earn a dog's respect or trust. Sharp as a tack intelligence, but intelligence and ability to solve complex problems can be used against an owner if they do not know how to take control of a stubborn, determined and willful breed that will not by nature always want to do things its owner's way. Pays to purchase a dog from health tested stock as it is prone to five health problems. Grain free dry food can be purchased at a reasonable price if a person shops around. NOT an outside dog, as it does not as a rule tolerate living in isolation kenneled outside well or left outside for prolonged periods of time. It is a one person dog breed that loves human companionship. I suggest your research all three breeds thoroughly and then make an informed decision which if any you can meet the needs of.
