I need to install a pump for condensation for my central air unit/furnace, because there is not a drain for it to dump into. The pump would have to be strong enough to pump the water overhead and across 15 feet to dump into a sink. The condensation tube is about 3-4 feet high coming out of the unit. I would have the water flow down to the pump and then have the pump send overhead. Is this OK to do? Are there strong enough pumps for the job? Is there a make and model of pump that can be recommended? Im in Chicago if that makes any difference in code, if any.And what price should I PAY ?And what size tubing(pvc) should I use? Does it matter?

Go to Home Depot or Lowe's and get one. They are all capable of doing the job. It should be 3/4" pvc pipe. Put a p trap in it as well.

Get a condensate pump with a box to contain the water. Also make sure it has a safety switch on it. A 3/8 OD copper or plastic tubing is all that is needed.
Set the box close to the furnace and coil, try to have it in a straight line below the drain on the Evaporator coil. Run a 3/4 PVC pipe down into the box, let it stick in about one inch. There will be a connection on the pump for the tubing to connect to, it will have a check valve in it. Run the tubing to where ever you are going to drain it to and secure it so that it will stay in place. There will be two 18 gage wires coming out of the box, and if your AC is just an AC and not a heat pump, you will have two wires going to the condensing unit out side, these may be inside one cable and you will have to cut the cover to get to just one of these wires. Cut one of these wires, (ONLY ONE) Tie one end of the wire you cut to one of the wires coming out of the box. Tie the other end of the wire you cut to the other wire coming out of the box. Put wire nuts on the wires for protection. Plug the power cord , that came with the pump into an electrical plug and you should be in business. To test it get a pitcher with a pouring spout on it and pour it in to one of the holes on top of the box, it should take about a half gallon. The switch should turn the pump on and the pump will pump the water out.

Thanks.a little advice goes a long way. This will be a project for an upcoming weekend soon!
