Air Conditioner Ratings, A Repairman Reviews The Brands...

With our air conditioner ratings you can cut through all the sales hype and find value. We have taken the time to search the manufacturers' literature and compare the units based on our years of hvac service industry experience. It truly is like you were taking a repairman shopping with you!

Our air conditioner ratings are divided into three categories. This ensures a fair comparison of features and breaks them down into separate price ranges.

The first category is basic air conditioners. These are the least expensive models. To qualify the unit must have an efficiency rating (seer) of at least 13. This is the minimum standard set by federal law for sale in the U.S.A.

The next category is premium air conditioners. These units have an efficiency rating of at least 15. These are usually two speed units. They are the next step up as far as price is concerned.

The last rating is for ultimate air conditioners. These units have an efficiency rating of greater than 20. They incorporate the most advanced features on the market. But, they are typically the most expensive.
We have given each brand a rating of from 1 to 5 stars. A 5* rating means that, if we were shopping for a unit for our home, that is the unit we would choose. When more than one brand has a five star rating, we would choose the least expensive one. If NA appears in the place of stars, it means that brand does not have a product available in that category or we could not get enough information to make a good choice.

For your convenience, we have included the web address for the manufacturers. We have also included our comments concerning the advantages/disadvantages of their products.
