Does Your Heating & Cooling System Make the Grade?

Posted by on in Resources

Home Heating and CoolingMost people confuse topics like an Energy Star rating with how efficiently their heating and cooling system is really operating. National Comfort Institute Certified Contractors use what they call an SER rating.

SER™ is a relatively new standard in the air conditioning and heating industry. It stands for System Efficiency Ratio. It's an efficiency rating of your installed system, including the effects of the ducting and the construction of your home.

When a typical heating and cooling contractor quotes the efficiency of the equipment (SEER or AFUE) and leads you to believe the new equipment will automatically deliver that efficiency, think again.

Typical installed equipment only operates at 55% to 70% of rated capacity. A 4 Seasons Heating & Air technician is trained and certified and will field-measure the installed efficiency of your old system. He may then recommend improvements while installing your new equipment and will then measure the new system's performance to prove the new system is functioning as designed. By taking this approach, we will help insure that you get the comfort and energy savings you're paying for.

It's Simple Math

Testing your HVAC system for the SER is Simple MathWhen we measure the SER™ of your system, the test reveals the ratio of actual heating or cooling delivery compared to the rated amount the equipment produced when the manufacturer tested the equipment.
For example if an air conditioner worked perfectly, it would be rated at a CSER™ of 100%. But if it only delivered half the cooling, the CSER would be 50%. In simple terms, 14 SEER air conditioning equipment could only operate like 7 SEER equipment. HSER™ and CSER™ HSER stands for Heating System Efficiency Ratio - it rates your heating system's efficiency. CSER represents Cooling System Efficiency Ratio and rates the efficiency of your air conditioning system.

This rating provides specific information about the performance of your system that has never been available to consumers before. More important, the testing that establishes the rating identifies exactly what needs to be done to your system to improve your comfort and efficiency.

You Can Increase Your SER Rating

While new high efficiency heating and cooling equipment may help, the number one factor in determining system efficiency is your duct system. Heating and cooling travels through ducts that are often too restrictive, damaged, poorly maintained, or improperly designed and installed from the beginning.

Your certified contractor can fix many of these problems and increase your SER. An NCI certified Combustion Analyst can also measure and adjust your furnace's combustion efficiency for maximum fuel savings.

Plan for Your Testing Today

Make sure to set aside ample time for your contractor to test your system. The time required depends on the size of your home. Normally, the testing takes between one and two hours. But stay for the show. The testing is clean, informative and entertaining.

It's important to understand that equipment ratings are only the potential efficiency of that component of the system under perfect conditions. Think of it as trying to rate your car's mpg based on just testing the motor by itself. Your expectations should be realistic. Most home's won't rate at 100% efficient. It has been done before, but it's very difficuem's efficiency depends on the duct system and the field-installation.

SER ratings of 90 or better are frequently achieved what s more important is that your system efficiency can often be increased by 25 to 50 the biggest benefit increase in comfort you will enjoy every day actually getting heating and cooling are paying for

Don't be fooled by imitations, as there are less than 5000 technicians in the world. 4 Seasons Heating & Air technicians are certified to perform this testing to protect your investment and to ensure the safety, efficiency, health, and comfort of your home.
