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 kept on the low setting, permitting your two-stage unit to operate 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.
Lennox’s Precise Comfort™ technology is an operating and control system that enables a furnace to adjust heat and airflow by very small amounts, as low as a 1 percent change. The system is automatic and works 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 work with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers provide your heating system an extra bump so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help reduce 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 made after Jan. 1, 2015, since heating and cooling contributes significantly to a home’s total energy usage. The requirements vary by region, so call A2Z Air Inc for the efficiency standards for Boynton Beach.

Lennox has a host of HVAC products with high efficiency ratings, which can help cut back 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 about the following:

  • Maintenance – ensuring your system obtains regular maintenance by a trained professional can keep your system operating 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 typically utilize.
  • Programmable thermostats – using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programed to offer 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:

  • 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, giving you a huge line of innovative solutions for your home comfort needs.
  • Commitment to excellence – We are devoted to providing customers not only quality products, but also quality service. You can trust Lennox dealers, like those of us at A2Z Air Inc, to help you find the right system for your home, expertly install it, and keep it running smoothly every time.

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

  • Eliminate – poor indoor air quality leaves your home full of with air pollutants floating around your home, so to improve IAQ, the first step is to rid as many pollutants as possible. You can easily do this is by cleaning and vacuuming at least once a week, regularly 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 difficult for airborne pollutants to escape. Products like our Healthy Climate® ventilation system help swap out stale air for fresh, filtered outside air.
  • Clean – good ventilation and routine cleaning are a start, but Healthy Climate® air filters, germicidal lights and PureAire™ purification systems take your IAQ to the next level by picking up microscopic particles, killing germs and removing particles and germs while destroying chemical vapors.
  • Monitor – programmable thermostats will help you keep an eye on the humidity levels and temperature to help prevent particles and germs from accumulating and keep your home comfortable.
Our Healthy Solution Finder lets you pick details specific to your family and home and will help you find equipment best suited to meet your needs. You may also consult with A2Z Air Inc experts who can make a recommendation based on their evaluations of your home and your current indoor comfort system.
Many homeowners believe that air conditioners make your home cooler, but it actually removes the heat from your home, moving 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 it outside. This procedure continues until the indoor temperature reaches the desired level that you set on your thermostat.
Due to the increasing 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 by region and carry varying requirements based on your location. A2Z Air Inc can help 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 will best suit your home, but the most reliable way to choose a system is by having your local A2Z Air Inc technician come out and perform a load calculation. This calculation considers your home’s: square footage, insulation value, amount of insulation, and a handful of other factors.
Yes, because dirt and other debris can impede your system’s ability to work efficiently. For heat pumps, it is normal to have frost or ice on them during the winter, but they also include defrost controls to ensure they work efficiently in that type 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 will take care of your cooling needs, but even when the high setting is in use, you may not realize it because it can generate such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and improved humidity control.
When your cooling unit freezes up, there are a variety 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 completed by a professional like those at A2Z Air Inc. Contact them at 561-270-6228 with any further questions you may have.
Choosing the best thermostat for your cooling system comes with a lot to think about. That’s why it’s nice to have such a wide variety of choices from A2Z Air Inc. Whether you’re in the market for for a programmable or non-programmable thermostat or want to join the smart home trend, there are a variety of thermostats that you have to pick from. Some thermostats will depend on what type of heating and cooling system you have, but the experts at A2Z Air Inc 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 meet both your heating and cooling needs throughout the year. When it’s hot outside it runs 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 unit as a whole system, efficiency may suffer.
  • As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These advances most importantly include improved heating and cooling efficiency, but also involve improved air handling, filtering and noise pollution reduction to name a few.
  • Heating and cooling systems that are more than 10-15 years old usually need to be replaced. Not only do they feature outdated technology, but they are also less efficient than more recent models. Buying a new indoor unit at the same time means you’ll have a matched system to provide you with even more 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 can go to this website to learn about the system’s status, energy production and environmental benefits. The site also shows carbon offsets as it happens.
Yes, an Internet connection is required for you to take advantage of the online monitoring system, which includes seeing 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 at no cost 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 right thermostat for you depends on your heating and cooling equipment. A2Z Air Inc sells programmable and nonprogrammable thermostats that can help increase the efficiency of your HVAC systems. Browse our available products or contact us at 561-270-6228 to learn more.
Heating and cooling can represent a significant chunk of your utility costs. 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. Besides purchasing a new home comfort system, consider these additional factors: 1. Is your product regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will run 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 parts 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 systems give you the ability to section off parts of your house and control the air differently in each room. Zoning tends to be ideal for when you have areas of your house that are infrequently used or when you and your family are always in disagreement of how hot or cold it ought to be inside. Zoning systems are almost noiseless and efficient, giving you more control over the comfort of your home. Find out more about the equipment available from A2Z Air Inc.
