With two-stage heating, furnaces may operate on two different levels: high and low. Since you can heat your home on the low setting a lot of the time, a two-stage furnace can work longer and more efficiently. Two-stage heating also operates more quietly than traditional furnaces and can provide more even heat distribution and fewer temperature swings.
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 better comfort.
The Department of Energy recently boosted the minimum efficiency levels for air conditions, and the standards vary by region. Contact Arnold's Air Conditioning of South Florida Inc at 772-205-3269 to find the requirements for the Stuart and West Palm Beach areas area.

Heating and cooling makes up a large portion of your monthly utility bill. Buying HVAC equipment with high efficiency ratings, such as SEER for air conditioners and AFUE for furnaces, is a simple step that can go a long way in decreasing energy output. Beyond these ratings, also ponder:

  • Routine maintenance – regularly having a professional tune-up your equipment will keep it working at its greatest potential.
  • Adding a zoning system – by focusing your heating and cooling on the rooms you use most frequently, you won’t have to pay to heat or cool areas of your home that aren’t used regularly.
  • Installing a programmable thermostat – the Department of Energy estimates that a programmable thermostat can reduce heating costs by up to 35 percent and cooling costs by up to 25 percent. Leave it up to your thermostat to turn down the heat when you’re not around and go back to your preferred temperature when you’re home.

There are a number of 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 at the forefront 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 Arnold's Air Conditioning of South Florida Inc, offer high quality service at all times, from your first consultation to your planned maintenance appointments.

Strategies to improve 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 regularly, 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 prevent 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 ensure even 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 diminish 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 make certain that your home is comfortable without letting humidity run rampant.
Try utilizing our Healthy Solution Finder, where you can select the indoor air quality issues that affect your home. After you choose the items that apply, the system will show the IAQ products that fit your needs. You can also call Arnold's Air Conditioning of South Florida Inc and walk our techs through some of the issues you experience. They can evaluate your home and needs and provide options and explanations.
It may come as a surprise that air conditioners don’t technically make your home cooler; they actually remove the hot air and transfer it outside. This hot air blows across a refrigerant coil on the indoor unit and then is sent to the outdoor unit where it is released. Your air conditioner pushes as much hot air outside as is necessary to reach the temperature you have set on your thermostat.
Minimum energy efficiency standards vary by region. Additionally, air conditioners, heat pumps and packaged units made after Jan. 1, 2015, have higher minimum efficiency levels than HVAC products manufactured prior to that date. The team at Arnold's Air Conditioning of South Florida Inc can help you determine the minimum requirements for Stuart and West Palm Beach areas, let you know if your current equipment meets those requirements or help you find a replacement air conditioner that does.
Your system’s service panel will have a white label on it, with your system’s model and serial numbers at the top. M/N stands for model number and S/N is the serial number.
Since equipment size needs differ for each home, the best way to figure out the correct size equipment for your home is to have a technician from Arnold's Air Conditioning of South Florida Inc come out to perform load calculation tests. The tests take measurements such as square footage, insulation value and amount, and more into account to determine your home’s HVAC equipment needs.
Yes – debris can inhibit your system’s ability to function effectively. It’s not uncommon for heat pumps to have frost or ice on them in the colder months, but many include defrost controls so they can work efficiently regardless of the weather conditions.
Your system could be freezing up for a number 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 homeowners take care of; however, you’ll want to call the professionals at Arnold's Air Conditioning of South Florida Inc at 772-205-3269 for other problems or if you have other questions or concerns.
Arnold's Air Conditioning of South Florida Inc offers a number of great thermostat options for your HVAC systems. The best thermostat for you will depend on a couple variables, such as whether you want one that’s programmable or not. No matter what kind of thermostat you’d like – or if you’re in the market for something that can fit with a home automation system – call Arnold's Air Conditioning of South Florida Inc to hear about which thermostats you can choose from. Our team will help you find one that’s right for your system, your family’s needs and your budget.
A heat pump can tackle both your home’s heating and cooling needs, offering you one HVAC system that can be used all year. Throughout the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and directing it outside; in the cooler months, this process is reversed. Heat pumps can be very energy efficient and may produce two to three times more heat than the energy it uses.
At Arnold's Air Conditioning of South Florida Inc, we do recommend replacing both your indoor and outdoor units at the same time because:
  • Outdoor systems are now built to work with their matching indoor system for the highest efficiency possible. When you replace one system but not the other, you may not see the same energy savings as if you had replaced them together.
  • Thanks to technological innovation, newer systems mean increased efficiency. This is true for HVAC products as well. While the advancements focus on greater heating and cooling efficiency, they also include benefits such as better air handling, filtering and noise reduction.
  • If your heating and cooling systems are 10+ years old, they need to be replaced. Older models have outdated technology that is likely contributing to higher energy bills due to poor efficiency. So by replacing your indoor system at the same time as your outdoor equipment, both your systems will provide better energy efficiency that helps you reduce your energy bills and keep your home more comfortable.
Yes. Your SunSource® Home Energy System has a communication module that transmits the system’s performance data to a website. The website includes information about your system’s status, energy production and environmental benefits, as well as carbon offsets in real time.
Yes, you will need an Internet connection if you want to make use of the system’s online monitoring system. The system allows you to view energy production and environmental information. The monitoring service is provided free for five years, and the performance-monitoring website is maintained by an independent third party, Enphase Energy Inc.
Rain will clean the modules by itself in most areas; however, if you live in a dusty area, you might see improved performance after periodically spraying the modules with water. Please note that high-pressure hoses and detergents should never be used to clean solar modules, as they can harm the product.

Your furnace and air conditioner can contribute significantly to your monthly energy expenses. However, these costs can be lowered with innovative and high efficiency products from Lennox®. Look for high SEER and AFUE ratings when you’re searching for a new air conditioner or furnace, respectively, as higher SEER and AFUE ratings mean higher efficiency products. If you’re not purchasing new heating and cooling equipment, consider factors such as: 1. Maintenance: Furnaces, air conditioners and other HVAC equipment run more efficiently when they are regularly maintained. 2. Zoning: When parts of your home are rarely used, you’re spending more money to heat or cool them to the same temperature as the rest of the house. A zoning system lets you section off different portions of your home and control the temperature by each area. 3. Programmable Thermostats: Programmable thermostats can help you lower your heating costs by 35 percent and your cooling costs by 25 percent, according to the U.S. Department of Energy.
A zoning system enables you to parcel your residence and heat or lower the temperature in each space differently. While these systems function well for buildings that have areas that are rarely occupied, they can also be great in situations where you and your family can’t agree on the temperature in various areas of your home. There are a number of additional pluses of zoning systems, such as efficiency and comfort. Browse our selection of zoning systems or give Arnold's Air Conditioning of South Florida Inc a ring to see how a zoning system could benefit your home.
