We had a unit that was working well but were informed that after the first of the year, we would no longer be able to get the unit serviced due to Freon no longer being available for private units, only commercial units.
Did some research, found out that was true and decided to purchase a new unit - mid August.
BIG MISTAKE! HUGE!!!
We were told that there was a "No Frustration" guarantee. We thought, 'no problem, we've had service with this company for over 10 years. '

Within two weeks, the unit started failing. We had to call b/c the unit stopped cooling on a Friday night. To their credit, they came out that night.

The first cold snap in October, the unit would not heat. They came out again. It started heating but within 30 minutes of their leaving, it shut down again. Someone else had to come out the next evening. Needless to say, we're frustrated. We had not had the unit 8 weeks yet and already, three service calls. We were told that the thermostat they installed wasn't that good for the heat pump. They offered to replace it if they had to visit again. Oh, and btw, before you find it, we'll go ahead and schedule someone to remove the trash in your attic before you find it b/c we know you'll be mad again when you find it. Yes, they left trash in our attic when they installed the new unit. That's the times someone had to come out in one week.

I brought up the no frustration guarantee. I was informed that my frustrations did not rise to the proper level of no frustration b/c we had not been without the use if the unit for more than 24 hrs.
So, I haven't had the unit 8 weeks and I've had to make 3 servings calls and your guys left trash in my attic, but none if that meets the no frustration guarantee. But we can offer two years of no payment if the monthly membership fee. I asked for that in writing.

A few more mild weeks go by and we don't really have to use the unit for a few weeks. Mid December, the outside unit causes the breaker to flip thereby causing the fan in the inside unit to run all night - and it's blowing cold air.

So again, we have a service call. Oh, and btw, we're we're charged teeth more monthly fees and I don't have that promise of no fees in writing. Could you take care of that? "We'll contact accounting and send you your letter, so sorry!"

The thermostat is replaced as is the breaker in the breaker panel inside the house.

First week of January, the unit is blowing cold air for over an hour. I have to go flip the new breaker, that isn't popped, too reset the unit and get some warm air so the fan will stop.
I still don't have my letter promising a two year period with no monthly membership fee.

I would rate this company a zero but one in the lowest they allow a person to go.
