As an HVAC contractor myself, I see both sides of the problem. When a customer calls for an install of a stove of any kind, they usually bought the stove somewhere already. Depending on who they bought it from, they may have the wrong stove for their application. If they do have the right one, they will usually have a lot of questions. This will usually take 2-4 phone calls. Then there will be the trip over to look at the project and assess their needs. This will take 1-3 hrs depending on the distance to the job. Then you will give them a price to do the install. Usually there is silence on the end of the phone and then the famous line " I will talk to my (wife or husband) and I will call you back". But now you have already spoke to them about the installation and it sounds like something they can do themselves. You as a contractor already have 2-3 hrs on the job and another 3-4 for the install and the homeowner thinks your price is outrageous. But you have overhead for the truck, ladder, tools, helper, workers comp, phone bill, gas, insurance etc,etc. Out of a standard install there might be 75-100 dollars left after paying everything and everybody and the homeowner says can I catch up with you next week so there are another 3-4 phone calls to get your money. Then they have a problem with a stove that you did not even provide and they hold up your payments because it isn't doing what the salesman said it would.Or the homeowner does not know how to operate it and soots up the whole house and wants you to pay for the cleanup because you installed it. Meanwhile the guy who sold it has already banked his 25-30% profit and is on to the next customer. Do this a couple of times and you will stay away from installing them for anybody.As they say "Been there done that". This is the normal scenario for this type of install. Talk to any stove shop and they will tell you they have a hard time finding a quality installer because of exactly these reasons. This is the truth.
