Energy News – Don’t Forget to Change Your Oil After Harvest

When the fieldwork is done, prior to winter storage, is the ideal time to change the lubricating fluids in your equipment. Don’t let the contaminants picked up during fall harvest and tillage sit in your engine’s crankcase or hydraulic system reservoir all winter long.

Drop that oil out now before it has a chance to corrode and shorten the life of your equipment.  Spring is busy enough without having to worry about changing oil. Replenish your equipment this fall with quality Cenex lubricants.

Plus, our Cenex Gift Cards for Gallons lubricants promotion is going on now. Earn a $50 Visa gift card for every 100 gallons of qualifying high-quality Cenex engine oils, hydraulic fluids, gear lubes, and greases purchased between November 1, 2020 and February 28, 2021.

Energy News – Winter Fuel Blending

With cold weather approaching, Landmark is here to help our customers prepare their fuel tanks and equipment for cold weather performance.  Following are some of the key points and characteristics of winter fuels and blending:

  • Cloud Point is the temperature (in degrees F) at which wax crystals begin to appear in diesel fuel.  For #2 based diesel fuel the Cloud Point can vary, however +14 degrees F is typical.
  • To insure proper fuel blending, the fuel (not air) temperature must be at least 10 degrees F above the Cloud Point.  Generally speaking, the fuel temperature needs to be +25 degrees F or warmer.
  • Cold flow additives (such as Winter Aid IV) do not reduce the Cloud Point of the fuel.  As the fuel cools below the Cloud Point, and wax begins to form, the cold flow additives modify the shape of the wax crystals and disperse them so they are less likely to plug filters.

Following are the Cenex Premium Fuels we offer here at Landmark and the operability temperatures our customers can be confident their equipment will perform down to when using these products:

  • Fieldmaster and Roadmaster Premium Diesel — Operability down to +15 degrees F
  • Winter Aid IV added to diesel fuel — Operability down to 0 degrees F
  • Seasonally Enhanced Fieldmaster and Roadmaster — Operability down to -15 degrees F
  • Wintermaster dyed and undyed — Operability down to -30 degrees F

Energy News – Propane Autogas School Buses Solve New Normal Challenges

While this school year is going to look different than any that have come before it, there’s still one thing districts can count on: propane autogas school buses can solve the challenges they face.

Quieter Operation: The buses operate noticeably quieter than diesel for a safe ride. Plus, all propane autogas school buses meet U.S. FMVSS and Canadian CMVSS motor vehicle safety standards, like conventional school buses.

Savings That Go Further: Propane autogas delivers the lowest total cost-of-ownership available. Districts could use those savings to afford more teachers, classroom supplies, and extracurricular activities.

Cleaner Neighborhoods: With propane autogas buses, students aren’t exposed to the emissions from older diesel buses that can aggravate asthma and cause other health issues.

Happier Drivers: Operators of propane autogas school buses report higher job satisfaction — they get to drive a quieter bus, and they don’t have to bring home the smell of exhaust.

Cenex® Premium Diesel Additives

Cenex® Premium Diesel has a more complete additive package for a more complete burn. Every gallon contains a tailored blend of seven additives that are terminally injected to ensure the highest standards of quality and performance.

As the final part of the Cenex Premium Diesel education series that kicked off in September, we will review the final three terminally blended additives that are found in Cenex premium diesel fuels, today we will focus on storage stabilizer, cetane improver and corrosion inhibitor.

Storage Stabilizer

For those who store large quantities of fuel for long periods of time, storage stabilizers are especially important. It works by forming a coating to prevent oxidation (a fuel’s process of breaking down), which help extend the life of the fuel. It also reduces gum and varnish buildup, helps protect the fuel with extreme changes in outdoor air temperature and increases injector life by optimizing combustibility.

Cetane Improver

Cetane measures a fuel’s ignition delay — or how quickly the air and fuel mixture combust in your engine. Cenex premium diesel has higher cetane content, which means a shorter delay and better ignition quality that lead to faster start-ups and reduced wear on the battery and starter. Not to mention, less pollution. Cenex premium diesel fuels have a typical cetane number of 47-49.

Corrosion Inhibitors

Corrosion inhibitors provide superior corrosion protection, preventing the formation of rust on metal parts. This slows the natural degradation of diesel fuel caused by exposure to oxygen and prevents leaks, blockages and breaks that can be caused by corrosion.

Cenex premium diesel provides a more complete burn to keep fuel and exhaust systems clean, increasing power and efficiency with less repairs or down time.

You Could Earn Tax Credits on HVAC Efficiency Improvements 

In December 2019, Congress passed legislation that renewed the tax credits for 2020 and made them retroactive back to 2018. For qualified HVAC improvements, homeowners may be eligible to claim the federal tax credits equal to 10% of the installed costs; a maximum tax credit of $500.

If you have purchased a system from Landmark Heating and Cooling in the past, or are thinking of purchasing a new system in the near future, you could be qualified for up to $500 in additional savings in the form of tax credits for 2018, 2019, and 2020! The tax credit is retroactive.

Be sure to consult your tax advisor before making taxes.

Landmark Heating and Cooling and Lennox Industries Team Up to Help a Neighbor

Landmark Heating and Cooling team members in Cottage Grove, WI, know that the frigid winter temperatures will be here soon. That’s exactly why they will be spending next Saturday morning installing a new furnace for helping a deserving Edgerton family. The recipients this year are the Gumbles. Teagan has health issues that are reactive to heat, cold, humidity, allergens and clean air so a program like Feel the Love can really make a difference in her quality of life.

For ten years the Landmark Heating and Cooling team has donated all labor and installation materials to install a brand new high-efficiency furnace, which is  generously donated by Lennox Industries, for a family whose existing unit is severely inefficient or unrepairable at no cost to the recipient.

The Wisconsin family was nominated and selected as part of the Feel the Love program, which asks members of the community to nominate people who are in need. Nominations for the program are accepted year-round, with recipients chosen based on specific criteria each September—before the temperatures start to drop.

“It’s such a rewarding program to be a part of,” says Tom Stangl, sales coordinator at Landmark Heating and Cooling, “There’s no better feeling than knowing that you’re bringing warmth and a sense of security to a well-deserving neighbor in your community. For me, it’s a great way to spend a Saturday.”

5 Tips To Beat The Heat

With exceeding temperatures ahead, here are a few tips to keep you “cool as a cucumber” this summer.

1.) Shut the Door and Close the Blinds

Closing the door behind you or shutting the blinds during the day is an easy step to keeping the hot sun from beating into the house and preventing the cool air from escaping. Closing off unused rooms in your home can also minimize the amount of area your air conditioner has to cool.

2.) Check Air Filter

It will not only improve air quality by removing the dust and dirt but also improve the energy efficiency of your HVAC system. Replacing your air filter every few months could save you some extra cash when it comes to your utility bill and extend the life of your air conditioner.

3.) Turn Off Lights and Reduce Stove Use

Keeping the rooms in your home darker can prevent extra heat escaping from light bulbs and the dim lighting will make the room seem cooler. Cooking with an oven set at 400-degrees will increase the temperature of your kitchen and surrounding rooms. If possible, try out a new grill recipe instead.

4.) Clean Vegetation Away from Outdoor Unit

Planting flowers or tall shrubs close to an outdoor HVAC unit can restrict the airflow to the system and it will become unable to cool properly. Plants should be at least 2-3 feet away from the unit so that it is also accessible in the event of repairs or maintenance.

5.) Program your Thermostat

A programmable thermostat will maintain a suitable temperature depending on the time of day instead of running a continual temperature all day. Consider investing in a programmable thermostat to keep the temperature of your home comfortable while still saving you money.
