3. Easier access

Single gauge metal cabinet allows for easier removal of high and low voltage redesigned knockouts
Metal condensate drain knockouts converted to rubber snap-in grommets for easier access
Electric heat knockouts replaced with a cover plate for easier removal during installation of electric heatstrips

4. Standardized cabinet fasteners

New Lennox Quantum™ coil improves reliability

More than 10 years of research and design went into the development of the Lennox Quantum condenser coils. These fortified aluminum tube and fin coils eliminate dissimilar metals which helps guard against fin loss due to galvanic corrosion. Although the coil is constructed of a fortified copper, the field connections to the unit are copper, allowing the contractor to use standard installation practices to install the unit.

Go Green and Save Money

Most people do not consider their heating and air conditioning when they are considering going green. People have tried to set their thermostat at a certain temperature and try to keep it there. Another idea is to set the temperature lower in the winter months when they are not home, but when they get home, they turn it up to warm up their house. This sudden burst of heat can make your bill go higher. The same is said when you are running your air conditioner. You walk into an overly stuffy house that does not even feel cool. This can also become a problem if a person suffers from any medical conditions that it is best if they do not get over heated. While the weather and your schedule may change, you can take control of the temperatures in your home, even while away.

Consider a Smart Thermostat

When you want to save money and not at the risk of health problems, you should consider a smart thermostat. With a smart thermostat you can control the temperatures in your home with the use of an app. This app can be downloaded onto your tablet, smartphone or any web enabled device. It can detect when you are leaving and it the app will automatically make adjustments so it will save you energy and money. When you return home, it can automatically adjust so you stay within a comfortable temperature. While you need to order Lennox air condition parts, ask about the IComfort S30, it can also monitor the quality of air in your area based off of your zip code. If you have for instance a high pollen alert, the system will automatically clean the air in your home by turning on a fan.

Benefits of an IComfort S30

  • Light Sensor
  • Motion Sensor
  • Climate IQ
  • 7 Day Forecast
  • Automatic Updates
  • Themed Screen Savers

Online Shopping Made Easier

It can be sometimes very difficult to find specific parts you need for your Lennox Air or Heating unit. This is why it is important to find and use the company that is very knowledgeable and has many parts, just not a few. When you are looking for a specific part, make sure you choose the online company that carries the most high quality parts for your Lennox air conditioner, while still being affordable. Lennox air conditioning parts are easy to find when you contact CozyParts.

Keep Your Air Conditioning Running Like New with Quality Parts

There is nothing better than walking into a cool air conditioned home after being out in the sweltering heat. People often do not think about their air conditioning until it finally breaks down on a hot summer day. Each year your unit loses some of its efficiency and over time the will begin to weaken and break down. That is why it is important to perform routine maintenance on your A/C unit each year. When you perform routine maintenance, you can replace the Lennox air conditioning parts to help keep your unit running efficiently and save you money by not having to replace your A/C. If a need to repair your unit, you should search online for a reputable company for your parts.

Why it is Important to Maintain Your A/C

During the heat of the summer, your electricity bill will rise from using your air conditioner. You want to make sure that it is operating correctly to help lower your bill. A well-maintained unit will use less energy than one that is not being properly taken care of. When you provide proper care and maintenance, it will keep the unit running more efficient saving you money. You will also save on major repairs if you replace parts before they become severely damaged. A dirty filter or even a small leak that is neglected can cause more damage to the unit costing you more money in the long run. You will want to provide maintenance to your unit to help save your warranty. Often in order for a warranty to be valid, you have to perform a routine maintenance on your air conditioner. The best benefit of having your unit maintained it will ensure that you and your family will stay cool during the summer.

Shop online with a Company you Can Trust

When searching for parts to your Lennox air conditioner search online for a company that can offer you the same service as if you were in their store. If you enjoy the convenience of shopping from home, but dislike not being able to speak with someone with questions you may have, you will want to find a well-established online store that provides representatives to answer any questions you may have. They will gladly help you find the right OEM part for your air conditioner and have your order on its way before you know it.

Lennox Announces Guidelines For Flood Damaged Furnaces and Air Conditioners

This information is created from Lennox Application Note ACC-63-11

Flood Damaged Heating & A/C Equipment


In the event Lennox HVAC equipment has been flood damaged or rendered inoperable due to a severe storm, the following steps should be taken before returning the equipment to operation:

  • Any unit that is or has been partially or completely submerged must have the electrical power supply disconnected immediately. The fuel supply to gas or oil burning equipment must be shut off.
  • Complete equipment service must be performed on the equipment. Safe and proper operation of the equipment must be verified. Failure to do so can cause further property damage and/or personal injury.
  • The extent of the damage will depend on the depth of the flood water, water type (fresh, brackish, etc) and the length of time that the unit was submerged.

Gas or Oil Furnaces & Heating Sections of Residential Package Units

  1. Ensure the electrical power supply to the equipment is off.
  2. The equipment must be thoroughly cleaned. This may require removal and disassembly dependent upon depth of water and length of time submerged.
  3. All electrical and safety components, such as those listed below, that have been under water must be removed and replaced with a new part:
    • Ignition control
    • Gas valve
    • Primary and secondary limits
    • Flame rollout switch
    • Combustion air inducer and pressure switch
    • Igniter
    • Blower motors
  4. Burners that have been under water must be thoroughly cleaned and/or replaced.
  5. Equipment insulation is secured to the cabinet with water-soluble glue. If insulation has been under water, it must be replaced with insulation of the same type, density and thickness as the original.
  6. Clean and thoroughly dry all electrical connections and any damaged wiring must be replaced.
  7. After repairs have been completed, an operational safety check must be performed on the equipment.
  8. The correct operation of all safety devices must be verified.

Air Conditioning or Heat Pump Systems & Refrigerant Sections of Residential Package Units

If the refrigerant circuit is damaged resulting in a refrigerant leak or is open to the atmosphere and has been under water, the complete system – (outdoor unit, refrigerant lines and evaporator or air handler) must be replaced.

If the refrigerant circuit is NOT open to the atmosphere, the following steps must be taken:

  1. Ensure the electrical power supply to the system is off.
  2. The equipment must be thoroughly cleaned, including the outdoor coil and evaporator in a furnace or air handler installation. This may require removal and disassembly dependent upon depth of water and length of time submerged.
  3. All electrical and safety components, such as those listed below, that have been under water must be removed and replaced with a new part: (this applies to both the indoor and outdoor equipment)
    • Electronic controls, defrost controls or electric heat controls and sequencers
    • Contactors
    • Motors
    • Refrigerant Pressure Switches (non-hermetically sealed)
  4. Equipment insulation is secured to the cabinet with water-soluble glue. If insulation has been under water, it must be replaced with insulation of the same type, density and thickness as the original.
  5. Clean and thoroughly dry all electrical connections and compressor terminals. Any damaged wiring must also be replaced.
  6. After repairs have been completed, an operational safety check must be performed on the equipment.

The correct operation of all safety devices must be verified.

System Accessories

All system accessories, such as thermostats, air filters, indoor air quality equipment, electrical devices and the air distribution system, should be evaluated using the guidelines listed above.


Flood damaged components are not covered by the Lennox limited warranty. New replacement parts carry a one-year limited warranty. Lennox further suggests making a thorough evaluation of the necessary repairs (labor and parts) in order to provide an accurate estimated the cost to the consumer. The estimate should also include an estimate for replacement equipment so the consumer can evaluate the options available and make the best decision for their situation and needs.
