Day and Night Air Conditioner Reviews and Prices Guide 2019

Day & Night has a reputation for value – Equipment that is better than average yet affordable.

In fact, the brand is nearly identical to one of the best-known and most expensive AC brands, but costs much less. More on that in the Model Analysis section below.

This Day & Night air conditioner guide lists the brand’s features, pros and cons, model analysis and prices.

Day & Night Top Features – Day & Night Pros

Here are some of the top advantages of buying one of the 10+ Day & Night central air conditioner models.

Quality is better than average, according to accumulated user data. Cost is average, so as we noted, you get good value with a Day & Night air conditioner.

Three performance options are available: Single-stage, two-stage and variable-capacity ACs. The details are found in the model table and analysis below.

What this gives you is a range of options to fit your budget and your climate – the warmer your climate, the faster you will be paid back for buying an energy efficient air conditioner.

Day & Night warranties are some of the best available. First, each unit in the lineup – even the cheapest 13 SEER models – are backed by 10-year general parts warranties.

But there’s more. Five models are backed by “No Hassle” unit replacement warranties of 1, 3, 5 or 10 years. This means that if the compressor or coil fails in that time, Day & Night will replace the entire unit, not just the part. The 1 and 3 year warranties are a bit of a gimmick, since failure in that timeframe is rare when the unit is properly installed. But the 5 and 10 year replacement warranties are a warranty upgrade worth having.

That higher-cost, bigger-name brand that’s almost exactly the same doesn’t offer unit replacement warranties.

The Day & Night Ion control gives you remote access with WiFi connectivity. This allows you to monitor and control your HVAC system from anywhere using a smart device and the app. This convenience option will also reduce your energy use and costs. For example, you can turn up the thermostat to use less energy while you’re away – and use the app to boost cooling on your way home. You’ll always arrive home to a cool, comfortable house.

Day & Night Cons

This brand is one of our highest-rated AC brands. But there are a few things to be aware of.

The Observer Communicating System is available as an option on top models. It is technology that allows all system components to share data with the thermostat-rather than just receiving commands. The advantage is optimal cooling and dehumidification. That sounds good, of course.

The downside is a greater risk of system failure. Plus, the upgrade for the equipment and thermostat costs more than $800.

Currently, we do not recommend communicating technology, as discussed here.

Day & Night’s variable-speed AC has five speeds. It runs at the lowest speed possible for quiet operation, more balanced cooling than a single-stage or two-stage model is capable of and better dehumidification. Those are pros, of course.

But the con is that most variable-speed ACs have 70 or more stages of modulation. The climate control is even better with those units. If you are very particular about indoor comfort, a true variable-capacity AC is recommended.

As you can see, there are three basic series, Constant Comfort Deluxe, Constant Comfort and Performance. These roughly equate to Carrier Infinity, Performance and Comfort.

That’s right. When you buy a Day & Night air conditioner, it will be nearly identical to a Carrier model. There are minor differences in some models that do not affect quality or performance.

International Comfort Products (ICP) is the parent company of Day & Night. ICP also makes identical brands Tempstar, ComfortMaker, Heil and others.

ICP is owned by Carrier. With Day & Night, you get Carrier quality at a much more affordable cost. Take a look at what a carrier ac cost in our Carrier Central Air Conditioner Buying Guide and Review.

1). Constant Comfort Deluxe is Day & Night’s top series. Both models offer staged cooling for better indoor comfort. Each is backed by a 10-year replacement warranty.

Recommendation: These ACs are ideal for very warm climates when premium climate control is preferred. This is especially the case if you want to upgrade to make it a communicating system. Just note our caution above.

To have a complete communicating system, you might need to replace your furnace too and include the Observer communicating thermostat.

2). Constant Comfort models are all single-stage units that have replacement warranties. Just one is Energy Star rated.

Recommendation: When you want better durability but don’t need premium efficiency, these are a good choice. These are the second-best units in quality with mid-grade prices. The 13 SEER C4A3 is only suitable for cool climates or where the AC won’t be used much (vacation home, guest apartment, etc.). It’s not efficient enough for warm/hot climates.

3). Performance models make up the largest series and the most affordable. The SEER range is the largest too, so there’s a unit for every climate from the coolest to the hottest.

All models are single-stage ACs. That means lower cost but indoor climate control isn’t as good. You might feel slight temperature swings, and the units won’t remove as much humidity as a two-stage or variable AC.

Recommendations: When cost is your primary concern, choose a Performance series AC. They’re all backed by 10-year parts warranties, so the quality is very good.

Be sure to choose one suited to your climate – the warmer your seasons are, the higher the efficiency should be.

The Performance 14 N4A4**C is a designed for areas where coastal salt spray is possible. Day & Night says it has, “Full coverage powder coat paint over galvanized steel and epoxy-phenolic fins for better protection against harsh coastal climates.”

The Performance 14 N4A4**C Compact NH4A4 is ideal for installation where space is tight – under a deck or for attached townhouses with minimal yard space.

Day & Night AC Prices

This price list has two columns.

The System Only price is just the air conditioner (also called a condensing unit or outside unit).

The System Installed price is the cost of installation equipment and labor. This includes the indoor coil, refrigerant and line set, and a new thermostat, if needed.

The reason for the range of prices is that each model is produced in units from 1.5 or 2.0 tons (18K BTU or 24K BTU) depending on model to 5.0 tons (60K BTU) for all models.

Day & Night AC Prices by Size

This is another way to sort out air conditioner prices for Day & Night models.

For this information to be useful, you should know what your current AC size is. It’s possible you’ll find it on the air conditioner plate where the serial and model numbers are found.

The AC model number often includes the size too. Look for these numbers as part of the serial number:

Model NumberCapacity  
181.5 tons
242.0 tons
302.5 tons
363.0 tons
423.5 tons
484.0 tons
605.0 tons

AC Unit SizeHome sizeEquipment costInstalled Cost

2.5 ton1301-1600 sf$1,285-$3,075$2,300-$5,000
3.0 ton1601-1900 sf$1,400-$3,150$2,395-$5,225
3.5 ton1901-2200 sf$1,650-$3,285$2,700-$5,300

5.0 ton2601-3200 sf$1,800-$3,500$2,800-$5,600

* The “Home Size” column is a very rough estimate. The warmer your climate is, the bigger the AC must be relative to house size. Have a load test done to get your air conditioner properly sized.

Whenever you replace an air conditioner, it’s a good idea to have the technician do a load test.

This is especially true if you have made your home more energy efficient through increased insulation, better windows and doors or other upgrades. If you have, then your new AC should be smaller than the current unit.
