Bought unit in 2020 and asked for 12 year warranty (parts &labor). Most of the contractors did not hesitate. Did pay roughly $13k for the unit but peace of mind is important.

I would just point out that the SEER rating measures the efficiency of the unit, not the cooling ability. The cooling ability is measured by tonnage rating, 3 tons, 4 tons, etc.

Second question: What indoor temperature do you prefer in the summer?

When you come to Florida and stay for any length of time, your blood thins out, especially as you get older. Set your thermostat at 78 degrees.

I also find the location of the thermostat to be critical as it needs to be more in the center of the house not near the garage or front door.

During 3 weeks of August 2022 I had no air conditioning. SunKool’s tech came every month and I complained that my temp setting would be fine in the morning but by afternoon my temp would rise to over 80. He gave me the same excuse over and over and told me nothing was wrong. Well, 8/2022 I had a complete ac breakdown. I had countless “Freon” boosts with no avail. That led to a coil replacement, then a capacitor replacement and not one but two replacements of my compressor ( the first one was defective). It wasn’t until a tech went into my attic and found a kink in a copper line that was likely the problem all along! Thankfully I was 3 months away from my 5 year parts and labor (actually have 10 year labor). I have switched to another maintenance company but I will always have a backup ac. I have leant it to several neighbors since then. My best advice is to be prepared. You don’t want to go through what I did.

The more important thing to be sure of is that your unit is sized correctly for your home...and you have adequate insulation, especially in the attic. We have no problem keeping the temp 20 degrees or more below outside temps. And more importantly our unit keeps the humidity at a reasonable low level compared to the summer outdoors.
