Nice to hear lots of happy campers. Note, the M series FH model is the newest and most efficient. Some dealers will try to sell their older FE models, which are less efficient.

I have installed 15 of these units. I only use singe units. I find that three singles cost about the same as one three head unit and are more reliable. I am an experienced plumber and electrician, so I do the rough-in, run the gas lines, mount the condenser/evaporator and then have a LICENSED HVAC person connect the tubing - purge - evacuate - purge - evacuate and maybe yet again. This is the most important part. If any moisture remains in the lines, you WILL have problems. A licensed HVAC person must do the final install or no warranty. Find an HVAC tech who does these all day, every day and really knows them. Anybody know about rebates?
