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 set on the low setting, enabling your two-stage unit to run for longer periods of time. Two-stage units also offer more even heat distribution, fewer temperature swings, quiet operation, increased air filtration and energy efficiency.

Modern furnaces are created with a number 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 bonus of modern furnaces is their ability to operate 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 run more efficiently and quieter than ever.

The Department of Energy recently increased the minimum efficiency levels for air conditions, and the standards vary by region. Contact Davis Heating & Air Conditioning at 540-369-3790 to find the requirements for the Rocky Mount area.

Davis Heating & Air Conditioning offers a number of HVAC products with high-efficiency ratings, which can help lower the amount of energy they require to operate. Aside from picking products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you should consider the following:

  • Making certain that your system receives regular maintenance by a trained expert 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 you don't typically utilize.
  • Having 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 want when you're home and increase or decrease the temperature while you're not around, helping you save on heating and cooling costs.
Davis Heating & Air Conditioning is well-known in the Rocky Mount 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 best solution for your home.

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

  • Poor indoor air quality leaves your home with lots of air pollutants floating around. So, to enhance 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 weekly, frequently washing linens and storing cleaning products safely.
  • Proper insulation is great for keeping your home warm in the winter and cool in the summer, but it also makes it harder for airborne pollutants to escape. We have products that help swap stale air for fresh, filtered outside air.
  • Good ventilation and regular 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 avoid particles and germs from building up while also keeping your home comfortable.
We suggest that you meet with one of the professionals at Davis Heating & Air Conditioning and have them evaluate your home and current indoor comfort system. We can help you choose 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 inside your home, directing 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 the hot air outside. This process continues until the indoor temperature reaches the desired level that you set on your thermostat.
Due to the 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 by region and carry varying requirements based on your location. Davis Heating & Air Conditioning can help answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're in the market for a replacement system.
These numbers are located on a nameplate or sticker that is near your systems service panel. The sticker will be white with black letters and have both of these numbers located around 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 is right for your home, but the most reliable way to size a system is by having your local Davis Heating & Air Conditioning technician come out and perform a load calculation. This calculation considers your homes: square footage, insulation value, amount of insulation, and a variety of other factors.
Yes, because dirt and other debris can hinder your systems ability to work efficiently. For heat pumps, it is common to have frost or ice on them during the winter, but they also include 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 is used, and when its cooler or more mild, the low setting gets the job done. Usually, the lower setting will take care of your cooling needs, but even when the high setting kicks in, you may not realize it because it can generate such even temperatures for your comfort. This may also mean a quieter cooling system, greater efficiency and enhanced humidity control.
Your system could be freezing up for a variety 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 should call the professionals at Davis Heating & Air Conditioning at 540-369-3790 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 great variety of choices from Davis Heating & Air Conditioning. Whether you're looking 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 pick from. Some thermostats will depend on what type of heating and cooling system you have, but the team at Davis Heating & Air Conditioning will be able to help determine what options meet your needs and your budget.
Heat pumps can be a tad confusing due to their name, but they actually meet both your heating and cooling needs year-round. When its hot outside it operates like an air conditioner in that it removes heat from your home, but when it cools off, the process gets switched around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and may produce up to two or three times more heat than the energy it uses.
Of course we suggest you 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 piece as a whole system, efficiency may suffer.
  • 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 typically need to be replaced. Not only do they consist of outdated technology, but they are also less efficient than newer models. Adding a new indoor unit at the same time means you'll have a matched system to provide you with better comfort and efficiency for years to come.
The communication module on your home energy system could send the system's performance records for each module to a website. You can 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 locations, rain will be enough to keep the solar modules clean. If you reside in a dusty or industrial area, periodically spraying the modules with water could help improve performance. However, detergents and high-pressure hoses should never be used to wash solar modules.
The proper thermostat for you depends on your heating and cooling equipment. Davis Heating & Air Conditioning offers programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. Browse our available products or contact us at 540-369-3790 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 Davis Heating & Air Conditioning can help decrease 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 consistently maintained? Whether it's a furnace or air conditioner, HVAC systems will operate more efficiently after regular maintenance checks.
  2. Would you benefit from a zoning system? If there are spaces 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 air differently in each room. These systems are ideal for when you have parts of your home that are rarely used or when you and your family are constantly in disagreement of what the temperature in each area of your home should be. Zoning systems are almost noiseless and efficient, allowing you more control over the comfort of your home. Learn more about the equipment available from Davis Heating & Air Conditioning.
