When choosing a company to service your heating, ventilation and air conditioning equipment in your home, we recommend looking for someone who is knowledgeable, honest, and reliable. Whether you choose
JANSEN or the competition, just make sure you receive the service or services that you have requested. In today’s environment it is far too common to be up-sold or for the quoted price to change once a service tech is at your home. Pressured sales and unnecessary products and service is not a sales tactic we subscribe to. We pride ourselves in being small enough to handle large tasks, but not too small to impact our friendly customer service. Established in 2001, we continue to grow and service of customers accordingly.
From a complete replacement of your furnace and air conditioning system to the modification of ductwork, rest assured that we have invested in the people and the most effective tools. This allows us to provide you with the best equipment to fit your home’s comfort.
We do not leave system installations to guess work. Proper sizing of furnaces and air conditioners is not left up to guessing your home’s square footage divided by 400 to 600 square feet per ton.
JANSEN utilizes state-of-the art software to calculate precise system requirements based on your homes design conditions. We calculate the actual heat that you are loosing from your home during the winter months to properly size your furnace, as well as the actual heat that you are gaining in your home during the summer months to properly size your air conditioner. Once the calculation is performed, we will provide you with a report and a written proposal for your review and approval.
With many brands to choose from we have performed the research for you, allowing you to make the best possible decision. Our equipment of choice is based on overall equipment reliability, performance, serviceability, and component integrity. While it is tempting to purchase the most widely advertised brand, we find that our near zero failure rate speaks volumes to the quality of our products that we install. Our equipment line must contain quality components backed by strong manufacturer warranties.
JANSEN understands that it is ultimately our responsibility to provide you with the best equipment and installation possible.
What does the efficiency percentage mean (95.0%, 92.5%, or 80.0%)?
In simple terms the percentage rating is related to the gas usage. The higher the percentage, the more heat (BTUHs) your furnace saves for heating your home. A furnace that is 80.0% will send 20.0% of the heat to the outside, likewise a 95.0% furnace will only send 5% of the heat outside. The less heat you send outside the more money you save.
Why should I consider a variable (EMC) speed motor?
Your furnace motor is one of the largest electrical wattage consuming appliances in your home. We recommend the ECM (Electronically Commutated Motor), since it is a super high efficiency programmable DC motor. On constant fan speed, the ECM consumes 60-80 Watts as compared to 400 watts for the induction motor. If you someone is spending $.09 and higher on kilowatts these are huge savings for our customers that run their blower on constant fan speed. Since, the furnace motor is used both in the summer and winter months, if there was ever a way to achieve considerable savings on energy efficient appliances, variable speed is the way to go.
What part of the furnace is unique to the manufacturer?
Generally speaking, a furnace is a box of assembled components purchased from other manufacturers. It is common for most furnace manufacturers to purchase components such as blower motors, contactors, transformers, inducers, pressure switches, limit switches, etc… verses making these components in-house. So the difference between one-furnace manufacturer from another is not the components in the furnace since most furnace manufacturers buy the same parts. The major difference is the design efficiency of the Heat Exchanger, and their warranty.
We are pleased to offer two stainless steel Heat Exchangers in our 95% efficiency systems.. Heat Exchangers have two parts, a primary and a secondary, the primary is made of 409 Ultra Stainless steel and the secondary is made of 29-4C superferritic stainless steel. From our no weld heat exchanger crimp design to, it’s “s-curve” shape, all the way to the 5 dimples that you see in the picture to the left, our heat exchanger is designed to give you the best possible heat for your home. We know of no other furnace manufacturer that makes 2 stainless steel heat exchangers.

Your air conditioning system is made up of two visible parts. The outdoor unit is called the condenser, which itself contains several components, the major of them called the compressor. The inside unit is called the evaporator coil and it is located inside your home either above or below your furnace. Both the evaporator coil and condenser are connected together via two cooper tubes. One tube is larger and is always insulated and the other tube is smaller and not insulated. These copper tubes carry the refrigerant in either a gas or liquid state and at times, a little mixture of both. The refrigerant in your air conditioning system will run at specific operating pressures and temperatures, based on manufacturer specification. It is important to install the system in accordance to these specifications in order to get the longest life and operational efficiency out of your air conditioning system.
Does it matter how it is installed?
The installation process for an air conditioning unit is not as simple as connecting two copper lines and turning the thermostat to cool. During the installation process it is necessary to ensure that inside these copper lines there are no particulates or outdoor air (oxygen, nitrogen, argon, etc…) that will contaminate the system. Proper brazing of copper lines requires using nitrogen to displace the oxygen, as to not create large amounts of carbon deposits inside the copper tubing, it also requires conducting a pressure test to evaporator coil specifications. Once this process is complete then the installer must evacuate or de-gas the system using a micron gauge to verify that the lines are in a vacuum. By always following these procedures you will eliminate those mysterious problems that occur with new air conditioners that occur just 1 to 4 years after their initial installation. Hint: Most problems that occur after a year of installation can be linked to a poor installation.
Why R22 or 410A?
The use of R22 will begin its major faze out in 2010, which means that it will be more difficult to purchase R22 refrigerant for your air conditioner. 410A is the next generation refrigerant and is safe for our environment. It contains no chlorine, so it meets the most stringent Environmental Guidelines.
What are louvers?
This is a metal jacket that surrounds all four side of your air conditioner, so that the internal coils are not exposed to the elements. This is a big must when considering a new unit, due to all the advantages and ease of serviceability.
What do I care about sound, the air conditioner is outside?
A loud air conditioner can be an annoyance; since it’s sound will travel inside at all hours of the day. Our
units are one of the quietest on the market today, which have a heavy-duty insulated sound blanket
surrounding the compressor to reduce noise and temperate transfer.

Geothermal Systems - certified by IGSHPA
Wherever you live, the temperature beneath your home remains constant regardless of the season. ClimateMaster® Geothermal Heat Pump Systems harness the stable underground temperature to provide heating, cooling, and hot water at remarkably high efficiencies. So high, in fact, that energy use can be cut by up to 80%. As the world’s largest and most progressive leader in clean, renewable geothermal technology, ClimateMaster leads the way with its award-winning Tranquility Series geothermal heat pumps.
Click the image below to view an interactive demonstration of how geothermal heat pumps work to save you up to 80% on your energy bills.

Nearly half the solar energy our planet receives is absorbed by the ground.
As a result, below the surface the earth remains a constant moderate temperature year-round. This provides an ideal source for heating and cooling your home. Geothermal systems use a sealed underground piping loop filled with circulating water and an ultra high-efficiency Tranquility heat pump to exchange heat between your home and the earth.
In the winter, the earth is your source of heat.
Water circulating in the piping loop absorbs heat from the earth and carries it to the heat pump, where it is concentrated and sent as warm, comfortable air throughout your home.
In the summer, the earth is your source of cooling.
The heat pump absorbs heat from the air in your home and transfers it to water circulating in the piping loop where it is absorbed by the earth. This provides cool, dehumidified and comfortable air throughout your home.
Unlike traditional systems that use the air to heat and cool your home, ClimateMaster® systems circulate water through a system of sealed underground piping loops that carry heat to and from the earth to the system. In the heating mode, the system uses the heat from the water to warm air that circulates throughout the house. In the cooling mode, the system reverses the process, taking heat out of the home’s air and circulating the resulting cool, dehumidified air instead.
Because the system has less work to do to reach the desired temperature setting throughout the year, the system is highly efficient and lowers operating costs. A fossil fuel furnace may be 80% to 90% percent efficient; a geothermal heat pump is amazingly 450% efficient.
Another advantage to a geothermal system installed in a new home is that from day one you will be cash flow positive, as the cost of the system each month is lower than the savings you realize on your monthly energy cost!
Boilers
People who use boilers for their main source of heat report that they love the kind of heat that a boiler provides, whether they have a steam boiler or hot water boiler. If you were thinking that there really is only one type of heat, you may want to reconsider. All you have to do is add adjectives to the beginning of the word heat. There is dry heat, wet heat, drafty heat, even heat, and uneven heat just to mention a few. The heat provided by a boiler will give you even, draft-less heat. That is opposed to drafty, uneven heat many forced air systems provide. There are many different combinations and configurations for boilers. There are gas boilers and oil boilers and a combination of the two with dual fuel burners. A boiler is simply a pressure vessel where water is heated for the purpose of providing heat somewhere for something. There are high pressure boilers and low pressure boilers. There are steam boilers and hot water boilers. Many of the same controls found on gas boilers and oil boilers are the same controls used on furnaces and water heaters.
