*SEER2 = Seasonal Energy Efficiency Ratio (2023 standard). The higher the SEER2 number, the less energy is consumed by an air conditioner. Estimates are the costs that are given and depend on the size of the unit and efficiency.

Understanding Residential Central AC Systems

Residential central air conditioners are ducted systems which cool the entire house using a system of air ducts. They are mainly divided into split systems and packaged units:

• Split-System Central AC: This is the most usual configuration. The sections are divided into exterior and interior. A furnace or air handler has an indoor coil that is connected with an outdoor condenser (condenser and compressor). Cooled air is forced to all the rooms by a blower in the furnace or air handler through the ducts.
• Packaged Central AC: A self-contained unit that houses the compressor, coil, and blower together in one outdoor cabinet. Packaged units sit on a slab or roof and connect directly to the home’s ductwork. They are often used in homes without basements or crawlspaces, or in warmer climates. Some packaged units also provide heating (gas or electric) in the same cabinet.
• Ducted vs. Ductless: The split and packaged central AC systems employ ducts. Ductless mini-split air conditioners (such as Mitsubishi) are ductless air conditioners that cool down zones. This article is all about the conventional ducted central air conditioning systems to cool the entire house.

Key Factors in Comparing Central AC Brands

• Energy Efficiency (SEER2): The SEER2 rating will give you the efficiency of the AC in cooling and the higher the number, the less your electric bills. The best brands construct units that are more than 13.4 SEER2, the minimum requirement of new central ACs in the United States. Lennox, Carrier, Goodman and others have models in the low 20s SEER and mid 20s. The greatest savings are experienced with homeowners in hot regions, but these high-efficiency units are expensive.
• Cooling Performance & Technology: There are two common types of compressors applied in modern central air conditioners. Units at entry level have single-stage compressors that are either on or off. Two stage or variable speed compressors that regulate output are better models. Carrier, Trane and Lennox top models employ inverter-driven variable-speed compressors. Most of the time they run at lower speeds, thus cooling is more consistent, humidity is easier to control and noise is reduced. Greater comfort and efficiency are achieved with advanced technologies like Carrier Greenspeed™ intelligence and Trane TruComfort™ system and multi-speed blowers. Other units even have an air purifier or UV lights to have purer air indoors. Most of the brands can be connected to heat pumps or solar panels.
• Noise Levels: The noise of the AC is expressed in decibels (dB). The lower the numbers, the quieter, and the quiet units are important in case the outdoor unit is placed close to bedrooms or patios. Some of the quietest are the Affinity series by York and the Infinity series by Carrier, and they run at 51-55 dB in low-speed mode (roughly equivalent to a quiet conversation). Single-stage units are 70 dB or above, and they are audible when they come on. Sound blankets on compressors, insulated cabinets, and sophisticated fan blades can assist leading brands to reduce noise. In case noise is an issue, select quiet models, which are labeled as such, and have a low dB level, and also consider vibration pads.
• Warranty & Support: Brands can be divided by warranty coverage. Some of them even provide 10-year limited parts warranty upon registration. The new Endeavor series offered by Rheem, as an example, can have up to 10 years parts and compressor warranties, a 5 year unit replacement or labor warranty, and 15 years rust-through protection on some models. Amana (Goodman high-end brand) is unique in that it offers lifetime limited warranties on compressors to original owners of some of the high-end models-in the event of compressor failure they will replace the compressor (sometimes the whole unit). ICP brands such as Heil have a warranty that is called the No Hassle Replacement that offers a free replacement of the unit in case of a major part failure. In comparing brands, look at the duration of warranty, which parts are covered, whether it is full unit or labor and whether extended warranties are offered. A good warranty will help you save on repair and indicates that the manufacturer has confidence. There is also a big network of authorized dealers (as in the case of Carrier or Trane) to get service or parts in case of need.
• Price Range & Value: Costs vary. The premium brands (Carrier, Trane and Lennox) tend to be the most expensive up front, often twice or even thrice the cost of the budget brands such as Goodman. These increased prices can incorporate improved build quality, increased efficiency and features. Budget brands continue to provide good cooling and could be a fit to homeowners with low budgets or limited time in the house. The mid-range brands (Rheem, York, American Standard, and others) are focused on the balanced prices, performance, and efficiency. To find the best value, compare the price of purchase to operating cost (energy efficiency), the anticipated service life and warranty. A more expensive unit will save on the bills and repairs. Obtaining multiple quotes of the same capacity unit allows you to determine price-to-value.
• Reliability & Durability: Home owners will desire an air conditioner that will serve them long. The reputation of a brand of being reliable is normally a result of good design and good quality control. Trane and American Standard have a reputation of being thoroughly tested (their slogan is something like nothing stops a Trane), and surveys of homeowners put them high on long-term reliability. Carrier and Bryant also have good build quality and durability when well maintained. Lennox is one of the best performing units, some HVAC professionals state that their proprietary parts are costly to replace, which may negatively impact perceived reliability or repair expenses. Goodman (and Amana) was previously perceived as more economical and with possibly shorter lifespan, however, with Daikin as its owner, the quality of the brand has increased greatly. Modern Goodman units have such features as heavy-gauge coil guards, improved corrosion protection, and all units are tested in the factory. Finally, the quality of installation and frequent maintenance is also a determinant of longevity, even the best AC brand may break down prematurely when it is not installed properly or maintained. In comparing brands, it is possible to get the insight of which brands are the strongest in the real world by reading consumer reviews and expert surveys.

Carrier

Carrier is a very well known and trusted brand of home heating and cooling. The company was started by Willis Carrier in 1915 and he also invented modern air conditioning.

Carrier offers a wide range of residential central air conditioners, including basic, efficient and high-efficiency smart systems. The Infinity® series offers variable-speed compressors and Greenspeed™ intelligence, which provides exacting cooling, and the SEER2 rating of 24.0, among the highest in the industry. Carrier units are constructed in such a way that they are quiet with some having a low decibel level of 51 decibels, which makes them one of the quietest options.

Carrier also has smart thermostats, its humidity control, and various air-purification options, which homeowners also appreciate to enhance indoor comfort.

Carrier has a reputation of developing powerful, dependable systems that are well tested prior to their exit out of the factory. Many of the Carrier central ACs will last 15-20 years with proper care. Carrier also provides 10-year parts limited warranty (including the compressor) on registration on its central ACs, which is the same as the industry. In order to maintain that warranty, the units have to be installed and serviced by NATE-certified or factory-authorized technicians.

A disadvantage is that Carrier is typically a high-end brand, so the upfront cost is typically higher than most competitors (installations can cost anywhere between ~3,000 dollars to 15,000 dollars or more on large, sophisticated systems). The company does not provide numerous models of the so-called budget type; even the Comfort series, which is the cheapest line of the company, is aimed at the quality and not the lowest price. Since not all the technology that Carrier utilizes is open-source, it may be difficult to replace some of the parts or repair them, and this may cost the company dealer network, which may increase the price of repairs.

It is worth speaking about Carrier sister brand Bryant. Carrier designs Bryant air conditioners and they are very similar in style and performance with slightly lower prices. The best Evolution® series by Bryant is as efficient as Carrier Infinity® (up to 24 SEER2) and has 10 years parts warranty. The two brands have a lot of dealers and other support systems. In sum, Carrier (and Bryant) are fine selections when homeowners seek a high-end, dependable air-conditioning system, and they are ready to pay more up front to get high efficiency, near-silent operation, and a large system of professional services.

Cons: 

Trane

Trane is commonly referred to as one of the most superior central air conditioners. It is engineering oriented on excellence and reliability. Trane is a tough unit builder, part of Trane technologies (previously Ingersoll Rand). It is demonstrated by its slogan, which is, It is Hard to Stop a Trane, as every AC is tested. The residential product line of Trane consists of XR (standard), XL (enhanced) and XV (premium variable-speed) series. The best models such as the Trane XV20i have inverter-driven compressors that are capable of varying capacity to meet precise cooling demand. These may reach as high as 21.5 SEER2 efficiency and maintain indoor temperatures constant. Trane systems also include all-aluminum Spine FinTM™ condenser coils (an exclusive proprietary design that allows greater heat exchange and corrosion resistance), and ComfortLink II communicating technology on more upscale models to allow integration with smart thermostats and diagnostics of the system.

Trane products are also purchased by homeowners since the brand is renowned to be durable and effective in the long run. Trane (and its close relative American Standard) scores well in customer studies, in the number of breakdowns. The compressor and the coils are also made to be durable. Several decades ago, many Trane systems are still in operation. The company provides a 10-year limited parts warranty and compressor (registration required) similar to Carrier. Some of the parts, e.g. Spine Fin coil and some controls, must be purchased through Trane dealers even when a Trane system requires repair. Also, in order to enjoy all the advantages of a communicating system, you typically require an official Trane thermostat and professional installation.

Another major problem of Trane is its prices. The Trane central air conditioners are usually very costly in the market. A Trane system may be at the higher end of the price range when installed on-site premium models in large sizes can cost up to $10,000-20,000 and more. The middle range two-stage units are even more expensive than the rival brands of equal products. Trane being very high quality oriented also has fewer models than some of its competitors and instead of having many niche products it has a few high quality products. Trane offers great comfort, low noise and confidence in the long term performance to those who can afford it. Tighter budget homeowners may then choose an American Standard unit (typically 5-10 percent cheaper), or consider other brands with a lower initial cost.

CONS:

Lennox

Lennox is a premium HVAC brand that is known to have ultra-high efficiency innovations. Lennox was founded in 1895 with a long history of heating and cooling experience, and it was frequently on the forefront of efficiency limits.

Lennox has three lines of residential central AC units, 1. the Merit series (low-end, low-cost comfort), 2. the Elite series (mid-range performance), and 3. the Dave Lennox Signature Collection (top-of-the-line models with the newest technology). The Signature Collection features such models as SL28XCV with the efficiency up to 25.8 SEER2, one of the highest SEER2 ratings of any central AC. These high-end Lennox models employ variable-capacity compressors, advanced control technology and integrate such features as climate-sensing and adaptive demand defrost (on heat pump models) to achieve maximum efficiency. Lennox also focuses on ecologically friendly refrigerants and has sold systems such as the SunSource® integration (utilizing solar panels to reduce power consumption).

A Lennox central AC can reduce the daily cooling expenses and make the home comfortable to the homeowner. It has variable-speed technology that provides consistent, effective cooling and good dehumidification. A lot of Lennox models are compatible with the iComfort® smart thermostat, which means you can control settings and set schedules using your smartphone even when you are not at the house. The majority of Lennox units operate in mid-50s to low-60s dB, which is a bit louder than the quietest Carrier and York units, but quieter than a number of other high-end brands. Lennox also enjoys a wide dealer base; there are Lennox Premier Dealers all over the country that ensure professional installation and service.

The two major disadvantages of purchasing Lennox are the price and the maintenance. The premium Lennox systems are priced just as expensive, or even more expensive, than the Carrier and Trane systems, which is too expensive to afford by most people. Lennox also applies proprietary parts and technology. When one of these components fails you might have to purchase original Lennox components which are sometimes costly and only accessible through Lennox dealers. According to some independent HVAC technicians, some of the Lennox replacement parts have a lower chance of being in stock in supply houses, which may result in a longer repair time should a dealer be located far away. It has also been reported once or twice that certain Lennox models are fussy and require professional tuning to perform. Lennox units however are very efficient and reliable in cooling when installed and maintained properly. They are an excellent option to those who desire the very best in efficiency (to reduce environmental impact or utility costs) and are prepared to spend to get a high-end system.

CONS:

American Standard

Trane has a sister brand called American Standard, which is produced by the same company (Trane Technologies) and has almost the same products. To the homeowner, this translates to the fact that an American Standard central AC provides you Trane engineering and reliability, at a price that is sometimes a little more affordable. The American Standard has three lines Silver (basic single-stage models), Gold (mid-range, some two-stage models), and Platinum (high end with variable-speed compressors and communicating technology) . The Platinum series ACs are as high as approximately 21.5 SEER2, and this is equal to the best of Trane. Practically, Trane XV20i is identical to an American Standard Platinum 20 variable-speed unit; the only difference is the badge on the unit and the dealer network available.

In terms of quality, American Standard is synonymous to Trane. They are manufactured in the USA and are tested through the same strict testing program. Most of the models even share the same parts (compressors, coils, electronics) as the Trane-branded ones. The owners of the American Standard ACs have been reported to be very satisfied with the cooling efficiency and durability of the ACs. The dealer network of the brand is a bit different than that of Trane, some HVAC contractors prefer one brand to another, but there is usually authorized American Standard service available in most locations. The warranty is also 10 years on parts and compressor when registered just like Trane.

The most efficient models of American Standard are compatible with Wi-Fi thermostat and are very silent. They are mid-range to high-end, as Trane is, and they do not compete on the cheapest of ends of the market. Their entry-level Silver series models are also dependable yet they cost more than the products of low-end brands.

Since the brand is not as popular as Trane among ordinary people, not all homeowners may take notice of it. However, the people who are familiar with it know it is basically Trane in a new package.

The same as Trane are the replacement parts and service procedures. You might have to use dealer channels to do some repairs. The positive side is that there is a well established chain of supply of parts due to the large market share of Trane/American Standard.

In case you desire Trane-level quality and you do not care whose name is on the unit, American Standard is a wise decision, which will save you some money. It is a good combination of performance, efficiency and reliability.

CONS:

Bryant

Bryant is a reliable brand of air-conditioning, which belongs to Carrier Global Corporation. Bryant products are based on Carrier technology but they are sold under the Bryant name and generally at a lower price.

Bryant is a company that has been operating in the home-comfort industry over one century. It is reputed with quality high-quality central air conditioners. The product line of the company is similar to that of Carrier: the highest Bryant Evolution® series is the equivalent of the Carrier Infinity series, the middle Bryant PreferredTM series is the equivalent of the Carrier Performance series, and the Bryant LegacyTM series is the lowest, the cheapest.

Bryant air conditioners are no less strong than Carrier as a brand: they are efficient, quiet, and have smart controls. The Evolution Extreme 24 air conditioner has the capacity to achieve 24 SEER, variable-capacity cooling, and it even regulates the humidity inside the house to the same level of comfort enjoyed in most Carrier Infinity systems. Sound-dampening insulation and smooth fan designs make most Bryant models quiet and keep them in the low-50 dB range when operating at low speed. Durability is comparable to that of Carrier units since they are made of the same parts and are produced according to the same manufacturing standards. The homeowners are guaranteed 10 plus years of quality service and most Bryant models have 10 years parts warranty once they are registered, which indicates how the company trusts the reliability of their products.

Both the Bryant and the Carrier offer the best quality air conditioning systems although the former is likely to be less expensive. To take an example, the Bryant Evolution system may be a few hundred dollars less expensive than the Carrier counterpart. This appeals to the shoppers who desire a high-end product at a lower price. Bryant also provides more local sales promotions since it is at times referred to as the attainable one. However, most of the Carrier trained dealers also sell Bryant, thus the same treatment is given to the units installed by the technicians.

The potential disadvantage is that Bryant operates the same designs as Carrier, which means that its key selling point is price. Depending on the location, Carrier may be more readily accessible than Bryant, and thus there may be a difference in model selection. The finest Bryant models (such as Carrier Infinity) employ superior electronics and possibly require expert installers and service technicians who are conversant with Evolution Connex control systems. In case you choose these models, you should make sure that your contractor is familiar with them. Briefly, Bryant is a good choice when you need the quality and efficiency of Carrier but are not willing to pay just to have a Carrier brand.
