What is two-stage heating?
Two-stage heating permits the furnace to heat at two levels of output: high for cold winter days and low for mild ones. Approximately 80 percent of the time, your homes heating requirements can be met when the furnace is left on the low setting, enabling your two-stage unit to run for longer periods of time. Two-stage units also provide more even heat distribution, fewer temperature swings, quiet operation, improved air filtration and energy efficiency.
What sort of technology comes with the HVAC systems that JonAire Inc carries?
JonAire Inc has a variety of brands and models that are more efficient than ever and make it easier to find the best match for your home. There are innovative systems that make heating or cooling your home more automatic, functioning similar to cruise control to make tiny adjustments to help meet your comfort demands with energy efficiency. Give us a call at 775-751-2372 to learn more about the technology we carry.
How will my new furnace work differently from my old one?
Modern furnaces are designed with a number of innovative features older furnaces don't have. Today's 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 benefit of modern furnaces is their ability to work 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.
How can I reduce my energy costs?
JonAire Inc offers a number of HVAC products with high-efficiency ratings, which can help reduce the amount of energy they require to run. 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 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 desire when you're home and increase or decrease the temperature while you're not around, helping you save on energy bills.

What can I do to improve my homes indoor air quality?
Improving your homes indoor air quality starts with four basic strategies:
- Poor indoor air quality(IAQ) leaves your home with lots of air pollutants floating around. So, to improve 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 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.
How do I know which indoor air quality product will work best for my home?
We suggest that you meet with one of the professionals at JonAire Inc 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.
How does an air conditioner work?
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 goes 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 process continues until the indoor temperature reaches the temperature you set on your thermostat.
What is the minimum energy efficiency standard for air conditioners in my state?
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. JonAire Inc 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.
How can I confirm the model and serial numbers for my cooling unit?
These numbers can be found on a nameplate or sticker that is near your system's service panel. The sticker is white with black letters and will have both of these numbers located near the top of the sticker. M/N denotes model number while S/N is your serial number.
How do I estimate what size equipment I should purchase?
There are a handful of ways to determine what size system is the best fit for your home, but the most reliable way to size a system is by having your local JonAire Inc technician come out and perform a load calculation. This calculation considers your home's: square footage, insulation value, amount of insulation, and a variety of other factors.
Can frost, ice, dirt or other debris keep the outdoor unit of my cooling system from operating effectively?
The short answer is Yes, because 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 include defrost controls to ensure they work efficiently in that type of weather.
What is two-stage cooling?
Two-stage cooling means that your cooling unit has two levels of operation. When summer is the warmest, 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 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.
Why is my system freezing up?
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 can take care of; however, you'll need to call the professionals at JonAire Inc at 775-751-2372 for other problems or if you have other questions or concerns.
What is the best thermostat to use for my cooling system?
Choosing the best thermostat for your cooling system comes with a lot to think about. That's why it is nice to have such a great variety of choices from JonAire Inc. Whether you're searching for a programmable or non-programmable thermostat or want to join the smart home trend, there are various thermostats that you have to select from. Some thermostats will depend on what type of heating and cooling system you have, but the experts at JonAire Inc will be able to help determine what options meet your needs and your budget.
What is a heat pump?
Heat pumps can be a tad confusing due to their name, but they actually take care of both your heating and cooling needs all year. When it's 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.
When replacing the outdoor unit, should the indoor unit also be replaced?
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 intended 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 improvements most importantly include improved heating and cooling efficiency, but also consist of 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 consist of outdated technology, but they are also less efficient than today's models. Getting 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.
What is the best thermostat for my home comfort system?
The best thermostat for you depends on your heating and cooling equipment. JonAire Inc offers programmable and nonprogrammable thermostats that can help enhance the efficiency of your HVAC systems. View our available products or contact us at 775-751-2372 to learn more.
What is the best thermostat for my home comfort system?
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 JonAire Inc can help lower 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 higher the number, the more efficient the product. Besides purchasing a new home comfort system, don't forget about these additional factors:
- Is your system consistently maintained? Whether it's a furnace or air conditioner, HVAC systems will run more efficiently after regular maintenance checks.
- Do you need 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.
- Are you taking advantage of a programmable or smart thermostat? According to the U.S. Department of Energy, programmable thermostats may decrease your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.
What are the benefits of zoning systems?
Zoning equipment gives you the opportunity to divide portions of your home and control the temperature differently in each part of your home. These systems are good for when you have areas of your home that are rarely used or when you and your family are often in disagreement of what the temperature in each area of your home should be. Zoning systems are quiet and efficient, giving you more control over the comfort of your home. Learn more about the equipment available from JonAire Inc.
