Two-stage heating allows the furnace to heat at two levels of output: high for cold winter days and low for mild ones. Around 80 percent of the time, your homes heating requirements can be met when the furnace is kept on the low setting, enabling your two-stage unit to operate for longer periods of time. Two-stage units also give more even heat distribution, fewer temperature swings, quiet operation, improved air filtration and energy efficiency.

Modern furnaces are designed with a variety of innovative features older furnaces don't have. Todays heating systems provide more even heating and are better at controlling 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 work 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 James Heating & A/C, Inc at 336-853-6070 to learn the requirements for the Lexington area.

James Heating & A/C, Inc has a number of HVAC products with high-efficiency ratings, which can help reduce the amount of energy they require to work. Aside from choosing products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you might consider the following:

  • Making certain that your system receives routine maintenance by a trained professional can keep your system operating at its top performance.
  • Zoning systems enable you to heat or cool only certain areas of your home, so you wont have to pay to heat or cool spaces that aren't used.
  • Using a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programmed to give you the comfort you desire when you're home and increase or decrease the temperature while you're not around, helping you save on energy bills.
James Heating & A/C, Inc is well-known in the Lexington area and you can rely on them to provide quality home comfort products. We carry a variety of innovative and high-quality products. We are dedicated to providing customers high-quality service and will make sure you find the right solution for your home.

Improving your homes indoor air quality starts with four basic strategies:

  • Poor indoor air quality leaves your home full of air pollutants floating around. So, to increase IAQ, the first step is to get rid of as many pollutants as possible. You can easily do this by cleaning and vacuuming at least once a week, frequently washing linens and storing cleaning products safely.
  • Proper insulation is ideal for keeping your home warm in the winter and cool in the summer, but it also makes it challenging for airborne pollutants to escape. We offer products that help swap stale air for fresh, filtered outside air.
  • Good ventilation and routine cleaning are a start, but air filters, germicidal lights and purification systems take your IAQ to the next level by capturing microscopic particles, killing germs and eliminating particles while destroying chemical vapors.
  • Programmable thermostats will help control the humidity levels and temperature to help stop particles and germs from building up while also keeping your home comfortable.
We recommend that you meet with one of the professionals at James Heating & A/C, Inc and have them perform an evaluation of your home and current indoor comfort system. We can help you determine which equipment will be best suited to meet your needs.
Many homeowners believe that air conditioners make your home cooler, but it actually removes the heat from your house, sending the hot air outside. That hot air moves 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 temperature you set on your thermostat.
Due to the high 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 regionally and carry varying requirements based on your location. James Heating & A/C, Inc can answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're looking for a replacement system.
These numbers can be found on a nameplate or sticker that is near your systems service panel. The sticker should be white with black letters and have both of these numbers located near the top of the sticker. M/N stands for model number while S/N is your serial number.
There are a couple ways to determine what size system will best suit your home, but the most reliable way to size a system is by having your local James Heating & A/C, Inc technician come out and perform a load calculation. This calculation considers your homes: square footage, insulation value, amount of insulation, and a handful of other factors.
The short answer is Yes. Dirt and other debris can inhibit your systems ability to work efficiently. For heat pumps, it is normal to have frost or ice on them during the winter, but they also feature 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 starts up, and when its cooler or more mild, the low setting handles the duties. Most of the time, the lower setting is able to take care of your cooling needs, but even when the high setting is in use, you may not realize it because it can produce such even temperatures for your comfort. This may also mean a quieter cooling system, greater efficiency and improved humidity control.
Your system could be freezing up for a number of reasons, but the most frequent 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 James Heating & A/C, Inc at 336-853-6070 for other problems or if you have other questions or concerns.
Identifying the best thermostat for your cooling system comes with a lot of considerations. Thats why its nice to have such a wide variety of choices from James Heating & A/C, Inc. Whether you're searching 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 choose from. Some thermostats will depend on what type of heating and cooling system you have, but the team at James Heating & A/C, 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 take care of both your heating and cooling needs throughout the year. When its hot outside it works like an air conditioner in that it removes heat from your home, but when it cools off, the process gets turned around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and could 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 created to work with to ensure efficient performance. When they aren't paired with the other part as a total system, efficiency can be diminished.
  • As with a lot of products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These developments most importantly include greater heating and cooling efficiency, but also include 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 have outdated technology, but they are also less efficient than todays models. Buying a new indoor unit at the same time means you'll have a matched system to provide you with improved comfort and efficiency for years to come.
The communication module on your home energy system may send the system's performance records for each module to a website. You may visit this website to learn more about the system's status, energy production and environmental benefits. The site also displays carbon offsets as it happens.
In most regions, rain will clean the solar modules off automatically. If you live in a dusty or industrial area, periodically spraying the modules with water may 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. James Heating & A/C, Inc offers programmable and nonprogrammable thermostats that can help increase the efficiency of your HVAC systems. Check out our available products or contact us at 336-853-6070 to learn more.

Heating and cooling can make up a large part of your utility bill. The innovative and high-efficiency heating and air conditioning products available from James Heating & A/C, Inc can help lower these costs. If you're searching for a new heating 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 system efficiency, and the higher the number, the more efficient the product. Besides purchasing a new home comfort system, think about these additional factors:

  1. Is your system regularly maintained? Whether it's a furnace or air conditioner, HVAC systems will run more efficiently after regular maintenance checks.
  2. Would you benefit from a zoning system? If there are rooms in your home that are rarely used, a zoning system will allow you to heat or cool only the most used areas of your house.
  3. Have you installed a programmable or smart thermostat? According to the U.S. Department of Energy, programmable thermostats may lower 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 portions of your home and control the temperature differently in each area. These systems are good for when you have parts of your home that are infrequently used or when you and your family are always in disagreement of the perfect temperature for the house. Zoning systems are quiet and efficient, allowing you more control over the comfort of your family home. Find out more about the zoning equipment available from James Heating & A/C, Inc.
