We had a Unico system installed last year in our Northern Michigan summer cottage. We did a lot of research, and received a lot of good advice from the Breaktime readers. It worked beautifully last summer, cooled the house and took out the sticky humidity.
We were busy congratulating ourselves on our good sense.
We had the system serviced and closed up for the winter by the very reputable firm that installed it, and then they started it up again in the spring.
Now the problem. It doesn’t heat well, and it doesn’t cool.
The company that installed it says that after 6 years of installing these systems without any problems they are having a raft of problems this summer.
Does this sound familiar to anyone out there? Misery loves company!

Too many variables to guess at... but if it worked fine last year...
You won't know anything until a tech comes out and connects gauges to the system.
It could have a leak... a leak in a factory made component or a leak in a field joint.
There have been industry wide QC problems with TXV valves since the 13 SEER mandate has taken effect- that part could have gone bad.
Just because a company is "reputable", that doesn't mean that they use a vacuum pump, a micron gauge or use nitrogen when the copper lines are being brazed. Shortcuts here during the installation process take time to show up, then the customer is stuck with the bill (again). R410-A systems are not forgiving to sloppy installation practices like R22 systems. Customers seeking the lowball price will pay dearly later.
