Two-stage heating enables the furnace to heat at two levels of output: high for cold winter days and low for mild ones. Around 80 percent of the time, your home’s heating requirements can be met when the furnace is set on the low setting, allowing your two-stage unit to work for longer periods of time. Two-stage units also offer more even heat distribution, fewer temperature swings, quiet operation, better air filtration and energy efficiency.
Precise Comfort™ technology is an operating and control system used in Lennox furnaces. The technology can automatically adjust heat by increments as little as 1 percent, increasing energy efficiency and helping you experience more comfort.

Modern furnaces are developed with a host of innovative features older furnaces don’t have. Today’s heating systems give you more even heating and are better at regulating airflow. Although the air coming out of your vents may seem cooler than your old furnace, the airflow is much better and more efficient.

Another perk of modern furnaces is their ability to work with other HVAC products as part of a high-efficiency whole home comfort system. When combined with a high-efficiency air conditioner, furnace blowers can more easily accommodate add-on cooling. Other innovations, such as Precise Comfort™ technology and variable speed motors, will help your furnace run more efficiently and quieter than ever.

The Department of Energy recently raised the minimum efficiency levels for air conditions, and the standards vary by region. Contact Guidry's Air Conditioning & Refrigeration Service at 985-537-6795 to find out the requirements for the Raceland area.

Lennox carries a variety of HVAC products with high efficiency ratings, which can help reduce the amount of energy they require to operate. Aside from choosing products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can think through the following:

  • Maintenance – making sure your system receives regular maintenance by a trained expert can keep your system working at its peak performance.
  • Zoning – zoning systems allow you to only heat or cool only targeted areas of your home, so you won’t have to pay to heat or cool spaces that you don’t usually use.
  • Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home according to your schedule. They can be programed to give you the comfort you desire when you’re home, and increase or decrease the temperature while you’re not around, helping you save on heating and cooling costs.

There are many reasons to go with Lennox, but the top three are:

  • Lennox is a name you know and trust – known throughout the world for quality HVAC products, you can rest assured Lennox will provide you with high quality equipment.
  • Innovative and high quality products – Lennox has been on the leading edge of innovation in the heating and cooling industry for years. High quality furnaces, air conditioners and home comfort systems include innovative features to help your home stay more comfortable and energy efficient.
  • Reputation of excellence – high quality products are not the only arena Lennox excels in. Lennox dealers, like Guidry's Air Conditioning & Refrigeration Service, give you high quality service at all times, from your first consultation to your routine maintenance appointments.

Strategies to increase your indoor air quality can be as easy as vacuuming your home to something as large as adding a new ventilation system. Overall, good IAQ involves four strategies:

  • Eliminate – decrease the pollutants floating in your air by cleaning your home often, particularly vacuuming carpet, washing linens and safely storing household chemicals.
  • Ventilate – make sure your home is well-ventilated to move airborne pollutants out of your home. In newer homes, well-done insulation will inhibit ventilation, so Lennox systems such as the Healthy Climate® ventilation system can help. These systems bring fresh air from outside into your home and direct the stale air out.
  • Clean – correct air filters, such as our Healthy Climate® air filters, will make sure the smallest particles don’t get through and are let out into your home. Germicidal lights can kill the germs that do make it through, and purification systems like the PureAir™ will help get rid of odors and chemical vapors.
  • Monitor – keep your humidity levels in check with a programmable thermostat. High temperatures and humidity levels can increase concentrations of mold, mildew and germs. A programmable thermostat will ensure your home is comfortable without letting humidity run rampant.
Try using our Healthy Solution Finder, where you can pinpoint the indoor air quality issues that affect your home. After you select the items that apply, the system will show the IAQ products that match your needs. You can also call Guidry's Air Conditioning & Refrigeration Service and walk our techs through some of the concerns you experience. They can evaluate your home and needs and provide options and explanations.
Most homeowners believe that air conditioners make your home cooler, but it actually removes the heat from your home, directing the hot air outside. That hot air flows across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing the heat outside. This cycle continues until the indoor temperature reaches the desired level that you set on your thermostat.
Due to the high amount of energy used by heating and cooling systems, the Department of Energy (DOE) hiked up the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after January 1, 2015. These levels are determined by region and carry varying requirements based on your location. Guidry's Air Conditioning & Refrigeration Service will be able to answer any questions you may have regarding these minimum requirements and let you know what choices are available when you’re in the market for a replacement system.
You can find these numbers on a nameplate or sticker that is near your system’s service panel. The sticker should be white with black letters and have both of these numbers located near the top of the sticker. M/N signifies model number while S/N is your serial number.
There are a couple ways to determine what size system is right for your home, but the most reliable way to determine the right size system is by having your local Guidry's Air Conditioning & Refrigeration Service technician come out and perform a load calculation. This calculation considers your home’s: square footage, insulation value, amount of insulation, and a number of other factors.
Yes, because dirt and other debris can impede your system’s ability to work efficiently. For heat pumps, it is not unusual to have frost or ice on them during the winter, but they also are built with defrost controls to ensure they work efficiently in those kinds of weather.
Two-stage cooling means that your cooling unit has two levels of operation. When summer is its hottest, the high setting starts up, and when it’s cooler or more mild, it operates on the low setting. Usually, the lower setting is able to take care of your cooling needs, but even when the high setting starts up, you may not realize it because it can generate such even temperatures for your comfort. This also means a quieter cooling system, greater efficiency and better humidity control.
Your system could be freezing up for a couple of reasons, but the most typical are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something you, the homeowner, can take care of; however, you’ll want to call the professionals at Guidry's Air Conditioning & Refrigeration Service at 985-537-6795 for other problems or if you have other questions or concerns.
Choosing the best thermostat for your cooling system comes with a lot to think through. That’s why it’s nice to have such a great variety of choices from Guidry's Air Conditioning & Refrigeration Service. Whether you’re looking for a programmable or non-programmable thermostat or want to join the smart home trend, there are various thermostats that you have to select from. Some thermostats will depend on what type of heating and cooling system you have, but the experts at Guidry's Air Conditioning & Refrigeration Service will be able to help determine what options meet your needs and your budget.
Heat pumps can be a bit confusing due to their name, but they actually take care of both your heating and cooling needs year-round. When it’s hot outside it works like an air conditioner in that it removes heat from your home, but when it cools off, the process gets switched around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and may produce up to two or three times more heat than the energy it uses.
Of course we think you should also replace your indoor system, but this is why:
  • All outdoor cooling systems have a matching indoor unit that they are intended to work with to ensure efficient performance. When they aren’t paired with the other part as a total system, efficiency can be affected.
  • As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These developments most importantly include greater heating and cooling efficiency, but also consist of improved air handling, filtering and noise pollution reduction to name a few.
  • Heating and cooling systems that are more than 10-15 years old typically need to be replaced. Not only do they consist of outdated technology, but they are also less efficient than newer models. Adding a new indoor unit at the same time means you’ll have a matched system to provide you with better comfort and efficiency for years to come.
The communication module on your SunSource® Home Energy System sends the system’s performance information for each module to a website. You may visit this website to learn about the system’s status, energy production and environmental benefits. The site also shows carbon offsets in real time.
Yes, an Internet connection is required for you to take advantage of the online monitoring system, which includes accessing energy production and environmental benefit information. The system’s performance-monitoring website is maintained by an independent third party, Enphase Energy Inc., and the monitoring service is provided at no cost for five years.
In most locations, rain will naturally clean the solar modules. If you live in a dusty or industrial area, periodically spraying the modules with water may help improve performance. However, detergents and high-pressure hoses should never be used to clean solar modules.
The proper thermostat for you depends on your heating and cooling equipment. Guidry's Air Conditioning & Refrigeration Service has programmable and nonprogrammable thermostats that can help improve the efficiency of your HVAC systems.

Heating and cooling can contribute to a significant amount of your utility bill. The innovative and high efficiency HVAC products available from Lennox® can help lower these costs. If you’re looking for a new heating and/or cooling system, look for products with high SEER ratings for air conditioners and AFUE ratings for furnaces. SEER and AFUE are a measure of equipment efficiency, and the higher the number, the more efficient the product. Aside from purchasing a new home comfort system, consider these factors: 1. Is your product regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will opperate more efficiently after regular maintenance checks. 2. Do you need a zoning system? If there are areas of your home that are rarely used, a zoning system will allow you to heat or cool only the commonly used spaces of your house. 3. Are you taking advantage of a programmable thermostat? According to the U.S. Department of Energy, programmable thermostats can reduce your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
Zoning equipment gives you the the comfort of sectioning portions of your home and control the temperature differently in each room. These systems are ideal for when you have areas of your house that are infrequently used or when you and your family are often in disagreement of how hot or cold it ought to be inside. Zoning systems are almost noiseless and efficient, enabling you to have more control over the comfort of your house.
