I have a absolutely old Heating and A/C device and I just want to update it

There are multiple things that I currently do not like about my Heating and A/C system, but i have a absolutely old system you could say.

It seems that nowadays my Heating and A/C system is absolutely out of date; The first thing I do not like is my control unit.

It is just a dial on the wall. I can adjust the temperature and that is about it. The other thing I do not like is the air ducts I have throughout my house. The collect dust and dirt, however all of that blows right into my property and after that my associate and I breathe it. I do not like feeling that my air quality is not that great. The last thing is that my boiler is getting pretty old. I have noticed a rise in my energy bills each month. I have also noticed that my property is not quite as warm as I would like it to be, then even some areas are spotty with heat, however some areas of the property are warm and others are cooler feeling. Since I have a problem with all of this, I am deciding to call a local Heating and A/C business to have them look at my system. I want to update everything that I have. I realize that this will be a absolutely extravagant situation for me, but however, it is something that needs to be done. I want to be updated with my Heating and A/C system. I want it to run better for my home. I want my air quality to improve. I want to be able to be in control of more things than just the temperature. I even want to feel warmth all over the property and not in only some spots.
