I bought my house in may 2002. It had a temp star 10 (rated seer 10) five ton nac060aka1 central ac with gas heating. The compressor is mounted on a concrete pad outside my house. The ac is a split unit with the heater mounted inside the house in the attic space with the other haft of the ac unit called a coil. The fan above the compressor was replaced last year ant the compressor disconnect was replaced at that time. I have not done any maintenance or other repair. The service repair man said the compressor is running two amp more than normal causing the disconnect terminals to overheat that cause the it to be replaced. the higher amperes are an indication that compressor will be failing soon. that was 15 months ago. He said that the unit used Freon R 11 which will be phase out soon and that the entire ac central ac unit would need replacement. The new AC units are rated 13 seer which the dept. of energy say is 40 percent better than a seer 10. so replacing it will be okay with me. The Tempstar 10 lasted 15 years and is still running- that's pretty good life. I have no complaints

Tempstar air conditioners are high-quality, durable, and reliable, and the company backs their products with one of the best air conditioner warranties in the industry. There are plenty of models to choose from in the Tempstar lineup. Many of them have great efficiency ratings, so you’ll save money by upgrading to a more energy-smart cooling system.

3 ton 16 seer heat pump 15 kw heat pack and it's been awesome. All I can say is, treat the guys doing your install like family and they will do you a good job. I feed them supper and we watched a movie after. I live in Waco, TX. It gets very hot here. It was 113 last week with 60% humidity. We keep the air on 65 and it has no problem. It cycles on and off like normal. Our energy bill went from $340 to $360. Now it's $120 to $130.

I have had four different units at my house live there for 50 years Tempstar has been there and is cooled the best for the past 5 years.

We have two zonal Tempstar central hvac units that were installed in 1995…have never really ever been serviced and are still going strong what can I say.
