Now, it should be said that every brand’s communicating system is different, proprietary. Quite a few HVAC techs recommend that their customers remove the communicating control and run the system as a standard two-stage AC. Worse, many HVAC pros steer clear of communicating systems because they can be challenging to diagnose when issues arise. The wall control offers WiFi connectivity with an app, and it’s attractive but costly. Communicating components and the thermostat/wall control ($350+) are expensive. The more important issue is communicating technology, and what we say is true for all brands that offer it. If you live where summers are scorching hot and/or extremely humid, you might want an AC with 20+ efficiency. While that’s quite good, the most efficient ACs from other leading brands range from 20 SEER to the Lennox XC25 with a 26 SEER rating. The most efficient models have a SEER rating of 19. The first is minor, in our opinion, but the second is of greater concern. These are among the Comfortmaker and Tempstar AC pros along with a good range of products are most efficiency and performance levels. All models, from top of the line to the least efficient have 10-year general parts warranties.įinally, the Comfortmaker NH4A4 and the Tempstar NH4A4 are compact 14-SEER ACs ideal for locations where space is tight. Other models have 5-year or 1-year replacement warranties. This means the entire condensing unit will be replaced if either part fails in the first 10 years. The Comfortmaker CVA9 and CVA7 and the Tempstar TVA9 and TVA7 have 10-year replacement warranties on the compressor and coils. While not a technology feature, we also like the warranties these brands offer on their top models. Data is constantly being shared, so the compressor will speed up and slow down, like cruise control, for the most balanced cooling and dehumidification. For example, in the TVA9 and CVA9 just mentioned, the communication between components would determine which of the 5 speeds the system runs on. Communicating technology allows system components such as the AC, thermostat and air handler (furnace) to share data to precisely balance the air conditioning level. The Observer Communicating technology on top models from both brands (see the Models table under the Communicating row) must be paired with the Observer Communicating thermostat to take advantage of this feature. an infinite-speed model, and the cost of these units is slightly less. You’ll notice little difference in cooling consistency with a 5-speed vs. Variable-speed models from most other brands have “infinite” levels of operation between 40% and 100% capacity. These are also called variable-speed compressors, since the compressor uses rotary technology and speeds up to deliver more air conditioning or slows down for less. The Tempstar TVA9 and Comfortmaker CVA9 have variable-capacity compressors with 5 levels of operation. These are solid brands with good efficiency and performance, but their features don’t necessarily set them apart. Comfortmaker/Tempstar Central Air Conditioner Unique Features Comfortmaker and Tempstar units have both “fancy” names like the Deluxe 19 AC with SmartSense and standard model numbers like TVA9. Most ICP product lines are unique, but some of the 13 SEER and 14 SEER models, including those designed for coastal environments where salt spray is an issue, seem to be identical to Carrier/Bryant. ICP is owned by United Technologies, the parent company of Carrier and Bryant too. Tempstar and Comfortmaker are International Comfort Product (ICP) brands along with Heil, Day and Night, Keep Rite and several others. Note: Before you dive into the specific brand review, we highly recommend you to read our elaborate Central Air Conditioner Buying Guide in advance, there are several crucial steps you need to take before you even start to think about the brand.
