Day & Night Gas Furnace Reviews | Consumer RatingsDay and Night Gas Furnace Reviews | Consumer Ratings - Day and Night offers two specific series of gas furnace models for use in residential and light commercial applications. The Day and Night Constant Comfort™ Series and the Day and Night Performance® Series. There are several different furnaces with various features to choose from among those in the two series models.

The efficiency ratings range from 80% AFUE up to 98% AFUE for Day and Night Gas Furnaces. With 80% AFUE being the minimum allowed for sale by any manufacturer in the USA these furnaces are usually the economy models. The other variety of furnace types available from Day and Night include modulating gas furnaces and two-stage gas furnaces with the lower end furnaces being single-stage.

Day and Night Gas Furnace Top AFUE

Premium model gas furnaces offer staging for the firing rate of the gas furnace. That allows the furnace to keep a better and constant temperature over single-stage gas furnaces. Day and Night meets this with their modulating gas furnace that is an Energy Star rated gas furnace. These furnaces are condensing type furnaces, which means they use a lot of the heat produced by the combustion process. Enough so that the moisture is condensed from the combustion gases use a condensation drain. Finally, they makes several of these types of gas furnaces.

Energy Efficiency and Gas Furnace AFUE

Just because you spend extra money to buy a high AFUE gas furnace does not mean you will have true energy efficiency. There are many factors to getting true energy efficiency. Among these factors are:

  1. Proper installation of the gas furnace
  2. Ductwork Integrity
  3. Home Insulation including energy-efficient doors and windows
  4. Home humidity levels

Day and Night also offers a communicating feature for their proprietary thermostat that is optional when you purchase their furnace. I say okay, but make sure they leave the conventional thermostat wire in the wall in case you decide later to switch back to a conventional thermostat. It will prevent you from having to run a new thermostat wire in case you do switch back. Furthermore, this may require you to call a professional to wire the new thermostat if you decide to switch back but at least the wire you need for the job is there and will save a lot of time.

Day and Night Gas Furnace Reviews | Warranties

The other area I always advise people about are the warranties that come with the new system. Moreover, make sure you read the warranty first of all and then make sure you comply with the requirements. Most warranties only cover labor. If you are by a premium model gas furnace, I recommend parts and labor warranty as labor can be quite expensive these days and sometimes cost more than the components. Lastly, make sure to register the warranty within the manufacturers required time frame.

Heat exchangers are another area to pay close attention to for gas furnaces. Day and Night has a good warranty on their heat exchangers, especially for the premium and mid-range models. You can’t get any better than a lifetime warranty on a heat exchanger. Furthermore, always read exclusions on any warranty. Some warranties expire when the property transfers to another owner. That can affect resale value. Additionally, always read the terms and conditions and understand what you are getting.

Day and Night Ion™ System Control | What is It?

Day and Night Gas Furnace Reviews

When you purchase a system that has the Ion™ System Control, you are buying a communicating system. It comes with the Ion™ System Control thermostat. Essentially, it gives you remote control and access through either the internet or from an app on your smartphone. Touted as an energy management system, Ion™ System Control gives you more control over your system than conventional thermostats. Ion™ System Control offers the following features:

  • Easy touchscreen control or use your smartphone
  • Scheduling for system setback
  • Maintenance reminders - never forget to change the filter
  • Real-time energy tracking
  • Local weather on the display
  • Zoning up to 8 zones
  • Dual-fuel heat pump compatible

Ion™ System Control is only available for specific models of Day and Night gas furnaces.

Modulating Versus Two-Stage Versus Single-Stage Gas Furnaces

What is a modulating gas furnace?

A modulating gas furnace has a variable firing rate that can modulate, typically, from ~40% to 100% of output heating capacity. Modulation requires a variable-speed blower and you will want a varialbe-speed inducer motor. If the demand is only 40% or lower why do you want your furnace running at 100%? A modulating gas furnace offers this capability over a single-stage gas furnace or a two-stage gas furnace. It also provides more even temperatures by reducing temperature swing.
