Two-stage heating allows the furnace to heat at two levels of output: high for cold winter days and low for mild ones. About 80 percent of the time, your home’s heating requirements can be met when the furnace is left on the low setting, enabling your two-stage unit to work for longer periods of time. Two-stage units also provide more even heat distribution, fewer temperature swings, quiet operation, increased air filtration and energy efficiency.
Lennox’s Precise Comfort™ technology is an operating and control system that allows a furnace to adjust heat and airflow by incredibly small amounts, as low as a 1 percent change. The system is automatic and runs similar to cruise control, making adjustments gradually to meet your comfort demands with energy efficiency.

Depending on how old your previous furnace was, you could experience a variety of differences. Furnaces today are developed to give more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces.

Additionally, new furnaces are created to operate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers offer your heating system an extra lift so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help decrease noise associated with operating your equipment and easily meet your family’s airflow needs.

The Department of Energy recently increased the minimum efficiency levels for air conditioners, heat pumps and packaged units created after Jan. 1, 2015, since heating and cooling contributes significantly to a home’s total energy usage. The requirements vary by region, so call Farnell Heating & Air Conditioning Inc for the efficiency standards for Mobile.

Lennox has a host of HVAC products with high efficiency ratings, which can help reduce the amount of energy they require to work. Aside from picking 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 gets regular maintenance by a trained expert can keep your system working at its top performance.
  • Zoning – zoning systems permit you to only heat or cool only specific areas of your home, so you won’t have to pay to heat or cool spaces that you use infrequently.
  • 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 away, helping you save on heating and cooling costs.

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

  • You know and trust the name – Lennox is recognized around the world for its quality home comfort products.
  • Innovation and high quality – Lennox is an industry leader, providing a complete line of innovative solutions for your home comfort needs.
  • Commitment to excellence – We are committed to offering customers not only quality products, but also quality service. You can trust Lennox dealers, like those of us at Farnell Heating & Air Conditioning Inc, to help you choose the right system for your home, expertly install it, and keep it working smoothly every time.

Improving your home’s indoor air quality starts with four basic strategies:

  • Eliminate – poor indoor air quality leaves your home filled with air pollutants floating around your home, so to improve IAQ, the first step is to get rid of as many pollutants as possible. You can easily do this is by cleaning and vacuuming at least once a week, routinely washing linens and storing cleaning products safely.
  • Ventilate – proper insulation is great for keeping your home warm in the winter and cool in the summer, but it also makes it harder for airborne pollutants to escape. Products like our Healthy Climate® ventilation system help swap stale air for fresh, filtered outside air.
  • Clean – good ventilation and regular cleaning are a start, but Healthy Climate® air filters, germicidal lights and PureAire™ purification systems take your IAQ to the next level by capturing microscopic particles, killing germs and removing particles and germs while destroying chemical vapors.
  • Monitor – programmable thermostats will help you monitor the humidity levels and temperature to help prevent particles and germs from building up and keep your home comfortable.
Our Healthy Solution Finder lets you choose details specific to your family and home and will help you find equipment best suited to meet your needs. You may also consult with Farnell Heating & Air Conditioning Inc experts who can make a recommendation based on their evaluations of your home and your current indoor comfort system.
Lots of homeowners believe that air conditioners make the air in your home cooler, but it actually removes the heat from your house, 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 hot air outside. This cycle continues until the indoor temperature reaches the temperature you set on your thermostat.
Due to the high amount of energy used by heating and cooling systems, the Department of Energy (DOE) raised the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after January 1, 2015. These levels are determined based on region and carry varying requirements based on your location. Farnell Heating & Air Conditioning Inc 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 is white with black letters and have both of these numbers located at the top of the sticker. M/N stands for model number while S/N is your serial number.
There are a few ways to determine what size system is the best fit for your home, but the most reliable way to size a system is by having your local Farnell Heating & Air Conditioning Inc 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.
The short answer is “Yes,” because dirt and other debris can hinder 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 feature 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 warmest, the high setting is used, and when it’s cooler or more mild, it operates on the low setting. Usually, the lower setting can take care of your cooling needs, but even when the high setting starts up, you may not realize it because it can maintain such even temperatures for your comfort. This also means a quieter cooling system, greater efficiency and improved humidity control.
When your cooling unit freezes up, there are a couple of reasons why it could be doing so. The most typical reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can change as a homeowner, but the others need to be done by a professional like those at Farnell Heating & Air Conditioning Inc.

Picking 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 Farnell Heating & Air Conditioning Inc. Whether you’re searching 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 pros at Farnell Heating & Air Conditioning Inc will be able to help determine what options are best for your needs and your budget.
Heat pumps can be a tad confusing due to their name, but they actually cover 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 reversed 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 suggest you 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 might be diminished.
  • As with a lot of 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 normally need to be replaced. Not only do they have outdated technology, but they are also less efficient than today’s models. Adding a new indoor unit at the same time means you’ll have a matched system to provide you with improved comfort and efficiency for years to come.
The communication module on your SunSource® Home Energy System sends the system’s performance records 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 real time updates of carbon offsets.
Yes, an Internet connection is needed 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 provided by an independent third party, Enphase Energy Inc., and the monitoring service is provided free for five years.
In most locations, rain will naturally clean the solar modules. If you are located in a dusty or industrial area, periodically spraying the modules with water can help improve performance. However, detergents and high-pressure hoses should never be used to wash solar modules.
The best thermostat for you depends on your heating and cooling equipment. Farnell Heating & Air Conditioning Inc offers programmable and nonprogrammable thermostats that can help improve the efficiency of your HVAC systems. View our available products or contact us at 251-471-2674 to learn more.
Heating and cooling can contribute to a significant portion of your utility bill. The innovative and high efficiency heating and cooling products available from Lennox® can help decrease 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. Other than purchasing a new home comfort system, consider these factors: 1. Is your equipment 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 spaces 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 using a programmable thermostat? According to the U.S. Department of Energy, programmable thermostats could reduce your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
Zoning equipment gives you the opportunity to divide portions of your house and control the air differently in each room. These systems are good for when you have spaces of your home that are rarely used or when you and your family are often in disagreement of the perfect temperature for the house. Zoning systems are quiet and efficient, enabling you to have more control over the comfort of your family home.
