$180 Maintenance Rebate Guarantee

Service Legends Guarantees that your SAVE-Certified System Rejuvenation will qualify for a $180 rebate through Mid-American Energy. If the maintenance performed by our SAVE-Certified Technician does not qualify your furnace or air conditioner for the full $180 rebate, we will take the rebate off the price of your investment. Homeowners must utilize Mid-American Energy for their gas on the furnace and Mid American must supply the electricity for the air conditioner. Only available on Service Legends SAVE-Certified System Rejuvenation.

SAVE-Certified System Rejuvenation Rebate Qualifications

Starting on Jan 1, 2014, homeowners are able to qualify for up to $360 in rebates to have the heating and cooling system professionally cleaned, serviced, adjusted and tested. Each piece of equipment can qualify for $180.

Not every heating and cooling technician is qualified to perform this level of service on the HVAC System. For a homeowner to receive the rebate of $180 per unit the following must take place:

1. The furnace Tune Up must be performed by a SAVE-Certified technician
2. The furnaces efficiencies must be improved by 10% of its rated capacity (10 SAVE Points)

SAVE-Certified stands for System Adjustment and Verified Efficiency. Technicians that are SAVE-Certified have taken part in specialized training regarding furnace and air conditioner performance. Part of this training is an exam that certifies the technician’s abilities to maintain and install heating and air conditioning equipment to produce the highest possible efficiencies and BTU output for your home.

How does this verification work?

The first step of obtaining a SAVE Tune Up rebate is to schedule a Service Legends SAVE-Certified System Rejuvenation. The SAVE-Certified technician that we send to your home will begin with a series of tests that determine the furnace or air conditioner’s current performance levels. This must be done before any work begins on the Tune Up. The reason for this pre-test is that the utility company wants to know how much improvement the tune up makes on the delivered performance of the system.

For the Geeks Out There That Really Want to Know: Measuring Your HVAC Systems Performance

The pre-test of your furnace or air conditioner consists of taking measurements of air speed and air temperatures at the unit to determine how much hot air a furnace is creating or how much heat an air conditioner is removing in a home. Think of going to the Dr. for a checkup. The first thing they do is take your vitals, temperature, weight and blood pressure. The technician will measure the systems temperature the same way a doctor does. This reading will show how effectively a furnace heats air entering the filter to the air leaving the furnace after its been heated. This is called the temperature rise. When the air conditioner is being test in cooling mode your technician will measure how much heat is being removed by the indoor part of the central air conditioner which is called an evaporator coil. An evaporators primary function is to absorb heat and humidity from the air in the home and then to transfer that heat through the refrigeration process to the outside. This is of course called temperature drop. There are several measurements that are taken from the furnace and air conditioner to determine how much heat is being removed or put in to your home.

dirty fan wheelThe next measurement your heating and air technician will take is called a static pressure test. This measures how hard the fan is working to move the air throughout the home. Think of this as a Dr. testing your blood pressure. This test will tell your technician how restrictive the ductwork is or if the fan is working harder than it should to heat or cool the home. It will also show if the filters are too dirty or restrictive in the system. This measurement is taken for heating and cooling modes as the fan works at two different speeds most times depending on what mode the system is in. Proper static pressures are absolutely critical in the performance of an HVAC system. Imagine running a marathon while breathing through a straw, how effective could you really be? That’s what happens with a heating and air conditioning system that does not have the proper air flow moving through it. Restricted airflow can be caused by dirty or undersized filters, improperly sized ductwork and dirty equipment.

The final calculation determines the amount of heat delivered in the home in comparison with the rated capacity of the furnace relative to the temperatures within the home during testing. For the air conditioner we would be calculating the amount of heat from your home relative to the outdoor ambient temperatures. Your technician will use your furnace or air conditioner manufactures data combined with all of the other testing to determine if your systems current efficiency can be improved by a large enough factor to qualify your heating and air conditioning system for the SAVE Rebate of $180 per unit.

How are the Adjustments Calculated?

To qualify for the SAVE Rebates the systems delivered performance must increase by 10 SAVE Points. The SAVE Points are a measurement of efficiency increased based off of the systems rated efficiency.

efficiency of furnaceFor example if we were to test a 100,000 BTU furnace we also must calculate what the rated output is. If the furnace is designed to be 80% efficient it means we should see 80,000 BTU of heat produced by the furnace. If after our measurements we see that we are only producing 65,000 BU of heat delivered from the furnace we can calculate 15,000 BTU is being wasted or not going to where it is supposed to. At this point it is obvious that the calculations indicate a significant improvement could be made to the system in performance. At this point it is time to begin the SAVE-Certified  System Rejuvenation. After completion of the furnace Tune Up we again measure the performance of the system to determine the improved output. For example the new measured BTU delivery is 75,000 after performing the furnace calibration and adjustments so we have improved the efficiency by 12.5 SAVE Points This is calculated by taking our

  • BTU Gained / Rated BTU in this case 10,000/80,000 = 12.5
  • This system would now qualify for a $180 rebate.

Performing the calculations for the air conditioners improved efficiency are slightly different. The capacity to remove heat with an air conditioner changes based of the temperature outside. The cooler the air outside the less heat a central air conditioner can remove from inside the home. When a manufacture builds an air conditioner the rated size that they classify it at is based off of a certain outdoor temperature that calculated during the engineering of the air conditioner. If we test at any temperature other than that number we will get a different rated efficiency. Because of that reason manufactures have rated capacity charts for equipment based off the outdoor conditions. We simply record the conditions outside and use that to determine the rated capacity at the time of testing. For example if a 36,000 BTU cooling unit is rated at 36,000 on an 85 degree day, its capacity may be 30,000 on an 80 degree day. This means if we test the system when it is 80 degrees the most we can get for capacity would be 30,000 BTU.

We use the same measurements of temperature change and fan performance to determine the delivered amount of cooling for the air conditioner as we did for the furnace. After we verify the operation we then are able to determine if we will be able to have the adjustments qualify for rebates.

For example if our rated BTU is 30,000 based off current outdoor weather conditions and we only measure 23,000 btu delivered we know we have 7000 btu that is not being delivered to the home. When we perform the SAVE-Certified System Rejuvenation on the central air conditioner we make changes to the system efficiency and it improves the BTU of heat removed from the home to 28,000 BTU and we have now increased our efficiency by 23 save points.

  • BTU Gained / Rated BTU 7000/30,000 = 23.33

What Adjustments can be made to Increase the Efficiency?

To gain efficiency is not an easy task. Being able to test the system is much easier than being able to improve the systems performance. The steps we use are similar to how a Dr. would improve your health based of the measurement that the Dr. takes when he first sees you. To explain better…

The first measurement we take is the systems Temperature. Similar to at the doctor’s office. We know that a healthy person’s temperature should be about 98.6 degrees. A furnace has a recommended temperature output based off the model and type of furnace it is so we want to get the delivering supply temperature as close to that number as possible. We do this by making sure the furnace is bringing cleanly and completely. This can involve cleaning gas burners or calibrating the amount of gas entering the furnace. Once we know this is correct we move to the next step.

The next step we take is the Static Pressure Measurements, like the blood pressure measurements the Dr. takes. If you have high blood pressure it is unhealthy the same way high static pressure is unhealthy for your furnace or central air conditioner. To correct high static pressures means sometimes cleaning the fan motor and fan blade that actually moves the air to reduce the amount of work it has to do. Often times cleaning the evaporator coil of the air conditioner will allow the proper amount of CFM (cubic feet per minute) of airflow. If the static pressure is high this may also doing duct modifications to the supply air plenum or the return air drop of the furnace. Think of a blocked artery in a heart. It causes high blood pressure. Sometimes it is minor and can be fixed with diet changes and exercise. Sometimes we can improve a systems performance performing high quality maintenance and cleaning procedures. A blocked artery may require a very in-depth surgery to correct as well which could be compared to changing or modifying the ductwork to allow better flow.

With the air conditioner we do not calibrate the gas pressures, we calibrate the refrigerant levels. This means getting the proper airflow inside first and then adjusting the refrigerant to properly remove the heat as the manufacture designed it. This is done by measuring the amount of heat absorbed inside, which is called super heat. And measuring the amount of heat removed by the outside unit. This is called sub cooling. Each manufacture has specific design standards and each system is calibrated using different numbers. No one system is the same so the technicians doing the work must be well trained to make these adjustments. This is often a great challenge in our industry as technicians that are not trained properly will often over charge or undercharge the system. Even just a couple ounces of refrigerant either direction will significantly reduce the performance and efficiency of the air conditioner.
