Indoor Air Quality

Do you find yourself frustrated with a home that feels either too hot or too cool? Or just as bothersome, a home that is too humid or too dry? At Polar Express Heating and Air we have a solution for you! One solution may be simply installing a Honeywell humidifier by one of our Guru's! It can help make your home more comfortable during the heating and cooling season. Just Call Polar Express Heating and Air today to get help with all of your indoor quality concerns, plus watch for our specials page... last month we gave away a year's supply of media filters to a client in Chenequa.

HEPA Air Filters

HEPA stands for High Efficiency particulate air filter. This filter does exactly what the name filters all the little particles that are circulating in your home.  HEPA filters help those who suffer from allergies, asthma and other respiratory illness. Call Polar Express Heating and Air for all of your HEPA filter questions and solutions. Plus, check out our blogs and specials...Bob Gilewski from Nashotah won a free HEPA filter at last years Lake Country Community Fest

UV Filters

What does a UV light filter have to do with your heating system? Well UV light filters work on purifying the air that circulates throughout your HVAC system. The UV light filter helps to destroy particles that are too small to be caught in a physical filter. For example, some areas found in Waukesha County that have high water tables can produce a musty smell in the air. UV filters can help eliminate or reduce these odors.  Ask one of our furnace Guru's during your next service visit or call Polar Express Heating and Air for more information.

Humidifiers / Dehumidifiers

Turning your temperature up in the wintertime will keep you warm, but it won't increase your home's humidity level. Daily activities such as showering, cooking and doing laundry don't produce enough moisture to keep your home's air from being too dry. According to medical experts, many viruses thrive in low humidity increasing the likelihood of catching colds, flu and upper respiratory ailments. A Whole-Home humidifier installed by Polar Express Heating and Air will deliver the perfect amount of moisture to your air making you feel more comfortable at lower thermostat settings. In fact, the EPA states that you can save up to 4% on your heating bill for every degree you lower your thermostat! For more information, call Polar Express Heating and Air.

Duct Cleaning

Why clean your air ducts? Well if your ducts look dirty...then they probably are! Think of your Duct system as the lungs of your home. If you have never cleaned your ducts, then think about it like a carpet in your home that hasn't been vacuumed in 10 years. Plus, dirty ducts or vents can contribute to health issues or harbor contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or environmental allergies. Duct cleaning or vent cleaning is a necessary task in most Lake Country homes at least every 10 years. Call Polar Express Heating and Air to find out more. Better yet...visit us at the Lake Country Community Fest where we gave away 3 whole house duct-cleaning jobs. Last years lucky winners lived in North Lake, Dousman and Merton.


Would you like to save 10% on your fuel costs? Then call Polar Express Heating and Air and have our Furnace Guru install a programmable set back thermostat in your home for energy savings. They are available for most gas and oil fueled central heating systems. Just try setting back the thermostat 5-10 degrees at night, then turn it up in the morning when the coffee is brewing and you will save up to 10% on your fuel cost...yes 10%! Many of our Polar Express Club members have had us install a programmable thermostat, like Joe B. who lives in Wales, and have saved as much as $15.00 per month. Call or Schedule an Appointment for more information, and look for us in the Hartland Hometown Parade!

Zone Heating Systems

Do you feel there are rooms in your home that always feel warmer or colder than others? There can be many reasons and explanations for this, but regardless of why a room's temperature is uncomfortable, there's one surefire way to even out your house's temperature...a zone heating system. System zoning involves multiple thermostats that are wired to a control panel, which operates dampers within the ductwork of your forced-air system. The thermostats constantly read the temperature of their specific zone, then open or close the dampers within the ductwork according to the thermostat's settings. For more information on Zone Heating Systems, call Polar Express Heating and Air! Our Furnace & Air Guru's service and repair all major brands of zoning systems such as Honeywell Zone systems, Trol-A-Temp Zone systems, and Dura Zone systems.

Hydronic Heating Systems

What is hydronic heating you ask? A hydronic heating system uses water to move heat from where it is produced to where it is needed, and recirculates it. A boiler is the piece of equipment used to heat the water, and hot water circulating pumps, distribution piping, and a fan coil or radiator dispense the heat throughout a home. While all this sounds technical and complicated, the Furnace & Air Guru's at Polar Express Heating and Air are here to help! We service and repair many boilers in the Lake Country area, and we are ready to help you with your hydronic heating needs wherever in Waukesha County you may live.

Carbon Monoxide Alarms

When you call Polar Express Heating and Air to come to your home, our Furnace & Air Guru's arrive in a fully stocked truck, including carbon monoxide detectors! In fact, Polar Express Heating and Air recommends that one be installed on every level of your home, in addition to one in the room where your water heater and furnace are located. We get calls every year from people whose carbon monoxide detector is alarming, and that's a serious concern! That also speaks to the importance of yearly maintenance of your furnace! Call us at Polar Express Heating and Air, or schedule an appointment to find out more, plus check out our specials page! During the Daylight's Savings Time and detector battery changing awareness, we gave away a carbon monoxide detector to two lucky clients from North Prairie and Genesee.

SIX Tips For A Healthy HVAC System

Now with summer winding down...keep your AC unit running at maximum efficiency with yearly maintenance! One of the most important parts of that maintenance is keeping the AC coils clean.


With Summer coming to a close, many of you may be planning some last minute travel in the next few weeks. Or whenever you plan on being away from home, even if it's only for a long weekend...Polar Express has a few helpful and important tips that we'd like to share for when you're planning to be away.


What a great question! Read on...
The inside of a furnace is pretty complicated from a component standpoint, but the principle of a furnaces operation is very basic. In order for a furnace to run it must be able to draw in intake air for combustion, evacuate the exhaust gases created from combustion, ignite the gas, move the warmed air through the home and dispose of condensation made during the process. All of these basic furnace functions can be interrupted if annual maintenance is skipped. In other words, as your furnace runs, it is creating problems for itself.
