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, permitting 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, increased air filtration and energy efficiency.

Depending on how old your previous furnace was, you could experience a host of differences. Furnaces today are created to offer 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 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 Jett's Heating & Air Inc. for the efficiency standards for McHenry.

Jett's Heating & Air Inc. has 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 can 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 specific 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 need when you're home and increase or decrease the temperature while you're not around, helping you save on heating and cooling costs.

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 one time during the 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 carry 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 avoid particles and germs from building up while also keeping your home comfortable.
We recommend that you meet with one of the professionals at Jett's Heating & Air Inc. and have them perform an evaluation of your home and current indoor comfort system. We can help you choose which equipment will be best suited to meet your needs.
Most homeowners believe that air conditioners make it cooler in your house, but it actually removes the heat from your house, moving the hot air outside. That hot air flows across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing the heat outside. This procedure continues until the indoor temperature reaches the temp that was set on your thermostat.
Due to the amount of energy used by heating and cooling systems, the Department of Energy (DOE) increased 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. Jett's Heating & Air Inc. will be able to answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're searching for a replacement system.
These numbers can be found on a nameplate or sticker that is near your systems service panel. The sticker is white with black letters and have both of these numbers located around 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 choose a system is by having your local Jett's Heating & Air Inc. 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 hinder 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 that type of weather.
Two-stage cooling means that your cooling unit has two levels of operation. When summer is in its hottest weeks, the high setting starts up, and when its cooler or more mild, the low setting gets the job done. Typically, 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 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 Jett's Heating & Air Inc..

Choosing the best thermostat for your cooling system comes with a lot to think through. Thats why its nice to have such a wide variety of choices from Jett's Heating & Air Inc.. Whether you're searching for a programmable or non-programmable thermostat or want to join the smart home trend, there are a number of thermostats that you have to choose from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at Jett's Heating & Air 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 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 reversed 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 intended to work with to ensure efficient performance. When they aren't paired with the other part as a total system, efficiency might suffer.
  • As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These advances 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 normally need to be replaced. Not only do they have outdated technology, but they are also less efficient than more recent models. Buying a new indoor unit at the same time means you'll have a matched system to provide you with even more 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 should visit this website to learn more about the system's status, energy production and environmental benefits. The site also shares carbon offsets as it happens.
In most areas, rain will clean the solar modules off automatically. If you are located 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 rinse solar modules.
The right thermostat for you depends on your heating and cooling equipment. Jett's Heating & Air Inc. sells programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. Check out our available products or contact us at 815-410-1128 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 Jett's Heating & Air Inc. can help lower these costs. If you're looking 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, consider these additional factors:

  1. Is your system consistently maintained? Whether it's a furnace or air conditioner, HVAC systems will work more efficiently after regular maintenance checks.
  2. Could your home use a zoning system? If there are areas 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. Does your home have a programmable or smart thermostat? According to the U.S. Department of Energy, programmable thermostats may reduce 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 air differently in each room. Zoning tends to be good for when you have areas of your home that are seldom used or when you and your family are often in disagreement of how hot or cold it ought to be inside. Zoning systems are quiet and efficient, enabling you to have more control over the comfort of your house. Find out more about the zoning systems available from Jett's Heating & Air Inc..
