Two-stage heating permits 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, allowing your two-stage unit to run for longer periods of time. Two-stage units also give more even heat distribution, fewer temperature swings, quiet operation, better air filtration and energy efficiency.

Depending on how old your previous furnace was, you could experience a host of differences. Furnaces today are designed to give 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 created to work 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 reduce noise associated with operating your equipment and easily meet your family's airflow needs.

The Department of Energy recently increased the minimum efficiency levels for air conditioners, heat pumps and packaged units created after Jan. 1, 2015, since heating and cooling contributes significantly to a homes total energy usage. The requirements vary by region, so call Gillman Heating and Air for the efficiency standards for Perry.

Gillman Heating and Air has a number of HVAC products with high-efficiency ratings, which can help lower the amount of energy they require to run. Aside from selecting products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can consider the following:

  • Making certain that your system receives routine maintenance by a trained technician 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 aren't using.
  • 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 desire when you're home and increase or decrease the temperature while you're not around, helping you save on energy bills.

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 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 weekly, frequently washing linens and storing cleaning products safely.
  • Proper insulation is good 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 removing 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 suggest that you meet with one of the experts at Gillman Heating and Air and have them evaluate your home and current indoor comfort system. We can help you decide which equipment will be best suited to meet your needs.
Most homeowners believe that air conditioners make your home cooler, but it actually removes the heat from your home, moving 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 process continues until the indoor temperature reaches the desired level that 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 by region and carry varying requirements based on your location. Gillman Heating and Air can help 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 denotes 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 determine the right size system is by having your local Gillman Heating and Air 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.
The short answer is Yes. Dirt and other debris can impede 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 are built with defrost controls to ensure they work efficiently in those types of conditions.
Two-stage cooling means that your cooling unit has two levels of operation. When summer is in its hottest weeks, the high setting kicks in, and when its cooler or more mild, it operates on the low setting. Usually, the lower setting will take care of your cooling needs, but even when the high setting is in use, you may not realize it because it can generate such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and improved humidity control.
When your cooling unit freezes up, there are a couple of reasons why it could be doing so. The most frequent 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 fixed by a professional like those at Gillman Heating and Air. Contact them at 478-202-3076 with any additional questions.
Picking 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 Gillman Heating and Air. Whether you're in the market for 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 select from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at Gillman Heating and Air will be able to help determine what options fit your needs and your budget.
Heat pumps can be a bit confusing due to their name, but they actually meet both your heating and cooling needs all year. When its hot outside it runs like an air conditioner in that it removes heat from your home, but when it cools off, the process gets reversed 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 advise you to 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 unit as a whole 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 improved heating and cooling efficiency, but also involve 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 consist of outdated technology, but they are also less efficient than newer models. Buying 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 might 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 shows 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 rinse solar modules.
The right thermostat for you depends on your heating and cooling equipment. Gillman Heating and Air has programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. Check out our available products or contact us at 478-202-3076 to learn more.

Heating and cooling can make up a big amount of your utility bill. The innovative and high-efficiency heating and air conditioning products available from Gillman Heating and Air can help decrease these costs. If you're shopping 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 larger the number, the more efficient the product. Besides purchasing a new home comfort system, don't forget 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. Could your home use 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. Are you taking advantage of 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 your home allows you you the ability to section off areas of your house and control the thermostat differently in each area. These systems are best for when you have spaces of your house that are rarely used or when you and your family are often in disagreement of the perfect temperature for the house. Zoning systems are nearly silent and efficient, allowing you more control over the comfort of your family home. Find out more about the zoning equipment available from Gillman Heating and Air.
