What is two-stage heating? 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 lot of the time, a two-stage furnace can work longer and more efficiently. Two-stage heating also runs more quietly than traditional furnaces and can provide more even heat distribution and fewer temperature swings. How does Precise Comfort™ technology work? 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. How will my new furnace work differently from my old one? Modern furnaces are designed with a number 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 bonus 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 operate more efficiently and quieter than ever. What energy efficiency standard should I look for in an air conditioner in McHenry? The Department of Energy recently boosted the minimum efficiency levels for air conditions, and the standards vary by region. Contact Jett's Heating & Air Inc. at 815-459-4700 to find the requirements for the McHenry area. How can I reduce my energy costs? 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 ponder: Routine maintenance – regularly having an expert tune-up your equipment will keep it operating 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 used often. Installing a programmable thermostat – the Department of Energy estimates that a programmable thermostat can lower 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 away and return to your preferred temperature when you’re home. Why should I buy from Lennox? There are various reasons to choose Lennox, but the top three are: Lennox is a name you know and trust – known around 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 Jett's Heating & Air Inc., give you high quality service at all times, from your first consultation to your routine maintenance appointments. What can I do to improve my home’s indoor air quality? Strategies to boost your indoor air quality can be as simple as vacuuming your home to something as large as installing 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 hinder 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 – proper air filters, such as our Healthy Climate® air filters, will make certain 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 ensure your home is comfortable without letting humidity get too high. How can I find out which indoor air quality product will is right for my home? Try using our Healthy Solution Finder, where you can pick the indoor air quality problems that affect your home. After you select the items that apply, the system will show the IAQ products that fit your needs. You can also call Jett's Heating & Air Inc. and walk our techs through some of the concerns you experience. They can evaluate your home and needs and provide options and answers. How does an air conditioner work? 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 moves as much hot air outside as is necessary to reach the temperature you have set on your thermostat. What is the minimum energy efficiency standard for air conditioners in my state? Minimum energy efficiency standards can vary by geographic location. 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 Jett's Heating & Air Inc. can help you determine the minimum requirements for McHenry, let you know if your current equipment meets those requirements or help you find a replacement air conditioner that does. How can I confirm the model and serial numbers for my cooling unit? Your system’s service panel should 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. What size equipment do I need for my home? Since equipment size needs are different for every home, the best way to find out the correct size equipment for your home is to have a technician from Jett's Heating & Air 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 unique HVAC equipment needs. Can frost, ice, dirt or other debris keep the outdoor unit of my cooling system from operating effectively? Yes – debris can affect 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. What is two-stage cooling? When an air conditioner 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 better humidity control. Why is my system freezing up? Your system could be freezing up for a variety 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 should call the professionals at Jett's Heating & Air Inc. at 815-459-4700 for other problems or if you have other questions or concerns. What is the best thermostat to use for my cooling system? Jett's Heating & Air Inc. has 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 in the market for something that can fit with a home automation system – call Jett's Heating & Air 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. What is a heat pump? 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 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 used. When replacing the outdoor unit, should the indoor unit also be replaced? At Jett's Heating & Air Inc., we do recommend replacing both your indoor and outdoor units at the same time because: Today, outdoor systems are built to work with their matching indoor system for maximum efficiency. When you replace only one of your systems, you may not see the same savings on your energy bills as if you had replaced them together. Thanks to technological advancements, newer systems mean improved efficiency. This is true for heating and cooling 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 lower your energy bills and keep your home more comfortable. Is it possible to see whether my solar HVAC system is performing at its full potential? Yes. Your SunSource® Home Energy System has a communication module that sends the system’s performance data to a website. The website shows your system’s status, energy production and environmental benefits, as well as carbon offsets in real time. Does the SunSource® communication module use an Internet connection? Yes, you will need an Internet connection if you want to utilize 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 provided by an independent third party, Enphase Energy Inc. Do I need to clean off my solar modules? Rain will clean the modules naturally in most areas; however, if you live in a dusty area, you could 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. Which thermostat is best for my home comfort system? Jett's Heating & Air Inc. can help recommend the right thermostat for you based on your home and current heating and cooling equipment. We carry a selection of programmable and nonprogrammable thermostats, which can help improve the efficiency of your home’s furnace and/or air conditioner. Take a look at our thermostats or give us a call at 815-459-4700 for more information. How can I improve my utility costs? 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®. Look for high SEER and AFUE ratings when you’re in the market for 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 work more efficiently when they are regularly maintained. 2. Zoning: When portions 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 portions 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. Why should I buy a zoning system? A zoning system enables you to parcel your house and heat or air condition each space differently. While these systems operate well for homes that have rooms that are rarely occupied, they could also be helpful in situations where you and your family argue about the temperature in different portions of your residence. There are a variety of additional benefits of zoning systems, like efficiency and comfort. Look through our selection of zoning systems or give Jett's Heating & Air Inc. a shout to see how a zoning system could benefit your home.
