Like any product you want to keep in good shape, HVAC equipment requires proper care in order to deliver the best benefits. Trained experts can service your heating and cooling products to make certain they’re working at their top potential and help prevent more costly repairs in the middle of the hottest or coldest months of the year.

With two-stage heating, furnaces may run on two different levels: high and low. Since you can heat your home on the low setting a majority of the time, a two-stage furnace can run 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 tiny as 1 percent, improving energy efficiency and helping you experience more comfort.

Modern furnaces are created 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 integrate 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 operate 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 Nisair Air Conditioning at 772-318-4252 to find the requirements for the Fort Pierce area.

Heating and cooling makes up a significant portion of your monthly utility bill. Getting new 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 consider:

  • Routine maintenance – regularly having an expert tune-up your equipment will keep it working at its highest 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 routinely used.
  • 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 many reasons to pick 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 Nisair Air Conditioning, 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 replacing a new ventilation system. Overall, good IAQ involves four strategies:

  • Eliminate – get rid of the pollutants floating in your air by cleaning your home routinely, 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 – the right 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 destroy 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 sure that your home is comfortable without letting humidity get too high.
Try using our Healthy Solution Finder, where you can select the indoor air quality concerns that affect your home. After you pick the items that apply, the system will show the IAQ products that meet your needs. You can also call Nisair Air Conditioning and walk our techs through some of the issues you experience. They can evaluate your home and needs and provide options and solutions.
You might be surprised to know that air conditioners don’t technically make your home cooler; they actually remove the hot air and direct it outside. This hot air moves 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.
Different regions have different minimum energy efficiency standards. Additionally, air conditioners, heat pumps and packaged units made after Jan. 1, 2015, have higher minimum efficiency levels than equipment manufactured prior to that date. The team at Nisair Air Conditioning can help you find out the minimum requirements for Fort Pierce, 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 is the model number and S/N is the serial number.
Since equipment size needs differ for each home, the best way to figure out the proper size equipment for your home is to have a technician from Nisair Air Conditioning come out to perform load calculation tests. The tests take things like square footage, insulation value and amount, and more into account to determine your home’s unique HVAC equipment needs.
Yes – debris can affect your system’s ability to function effectively. It’s normal for heat pumps to have frost or ice on them during the winter, but many include defrost controls so they can work efficiently regardless of the weather conditions.
When a cooling system uses two-stage cooling, it means that there are two levels of operation. This allows the system to work as efficiently as possible since there is one level for milder weather and another for harsher weather that demands the system work harder. Two-stage cooling also enables slight temperature changes so you don’t experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation and enhanced 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 Nisair Air Conditioning at 772-318-4252 for other problems or if you have other questions or concerns.
Nisair Air Conditioning carries a number of great thermostat options for your HVAC systems. The best thermostat for you will depend on a variety of 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 looking for something that can fit with a home automation system – call Nisair Air Conditioning 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 covers both your home’s heating and cooling needs, offering you one HVAC system that can be used in all four seasons. Throughout the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and moving 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 used.
At Nisair Air Conditioning, 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 maximum efficiency. When you replace just one of your systems, 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 over 10 years old, they need to be replaced. Older models have outdated technology that is likely costing you money 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 decrease your energy bills and keep your home more comfortable.
Yes. Your SunSource® Home Energy System has a communication module that sends 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 utilize the system’s online monitoring system. The system enables 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 ruin the product.
Nisair Air Conditioning can help recommend the right thermostat for you based on your home and current heating and cooling equipment. We carry a variety of programmable and nonprogrammable thermostats, which can help increase the efficiency of your home’s furnace and/or air conditioner. View our thermostats or give us a call at 772-318-4252 for more information.
Your heating and cooling equipment can contribute significantly to your monthly utility bills. However, these costs can be decreased with innovative and high efficiency products from Lennox®. Keep an eye out for high SEER and AFUE ratings when you’re ready to purchase a new air conditioner or furnace, respectively, as higher SEER and AFUE ratings mean higher efficiency products. If you’re not looking for 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 areas 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 enables you to section off different parts of your home and control the temperature by each area. 3. Programmable Thermostats: Programmable thermostats can help you reduce 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 air condition each area differently. While these systems function well for buildings that have parts that are seldom visited, they could also be great in situations where you and your family can’t agree on the temperature in various areas of your house. There are a variety of additional benefits of zoning systems, such as efficiency and comfort. View our selection of zoning systems or give Nisair Air Conditioning a call to see how a zoning system could benefit your home.
