With two-stage heating, furnaces may work 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 operate 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.
Lennox’s Precise Comfort™ technology is an operating and control system that allows a furnace to adjust heat and airflow by very small amounts, as low as a 1 percent change. The system is automatic and operates 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 provide 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 designed to integrate 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 lessen noise associated with operating your equipment and easily meet your family’s airflow needs.

The Department of Energy recently raised 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 James Heating & A/C, Inc for the efficiency standards for Lexington.

Heating and cooling makes up a large 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 reducing energy output. Beyond these ratings, also think about:

  • Routine maintenance – regularly having an expert tune-up your equipment will keep it operating 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 decrease 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.

Improving 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 eliminate 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 more 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 frequent 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 building up 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 James Heating & A/C, Inc experts who can make a recommendation based on their evaluations of your home and your current indoor comfort system.
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.
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 products manufactured prior to that date. The team at James Heating & A/C, Inc can help you find out the minimum requirements for Lexington, let you know if your current systems meets those requirements or help you find a replacement air conditioner that does.
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 is the model number and S/N is the serial number.
Since equipment size needs vary by home, the best way to figure out the correct size equipment for your home is to have a technician from James Heating & A/C, 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 limit your system’s ability to function effectively. It’s normal for heat pumps to have frost or ice on them in 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 more even temperatures so you don’t experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation 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 done by a professional like those at James Heating & A/C, Inc. Contact them at 336-853-6070 with any further questions you may have.
James Heating & A/C, Inc 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 James Heating & A/C, Inc to hear about which thermostats you can choose from. Our team will help you find one that’s best 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 in all four seasons. During the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and transferring 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 James Heating & A/C, 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 the highest efficiency possible. When you replace one system but not the other, you may not see the same energy efficiency levels as if you had replaced them together.
  • Thanks to technological innovation, newer systems mean increased efficiency. This is also true for HVAC systems. While the advancements focus on higher heating and cooling efficiency, they also include benefits such as better air handling, filtering and noise reduction.
  • If your heating and cooling systems are more than 10 years old, they need to be replaced. Older models have outdated technology that is likely adding to your energy costs 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 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.

Your heating and cooling equipment can contribute significantly to your monthly utility bills. However, these costs can be reduced with innovative and high efficiency products from Lennox®. You’ll want to 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 signify 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 work 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 may 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 lets you parcel your residence and heat or lower the temperature in each part differently. While these systems operate well for buildings that have areas that are infrequently occupied, they could also be helpful in situations where you and your family can’t agree on the temperature in different portions of your residence. There are a number of additional pluses of zoning systems, such as efficiency and comfort.
