When buying high efficiency HVAC equipment you must look past the brochure and find a dealer that knows the facts. Everyone wants to save money on there utility bills and purchase equipment that has a good rating but don’t let the brochure or a fancy sales man fool you into paying for extra efficiency you will never get.

Miller Plumbing Heating Cooling knows the facts about getting the best value when upgrading your old system. Here are a few quick tips to keep in mind.

1. High efficiency boilers are great for saving money on your gas bill. However when the water temperature is over 140 degrees as with cast iron radiators or cooper fin tube it is very hard to get over 90% AFUE. The lower the water temperature the higher the efficiency.

2.High efficiency forced air furnaces  need to be sized correctly to get the rated efficiency. Bigger is not always better. A high efficiency furnace that short cycles and dose not condence because the furnace is over sized   wastes money.

3. Air conditioners and heat pumps are sold based on there SEER rating the higher the number the less electricity it uses.

Right -WRONG. When installing a new furnace matching the correct A-Coil line kit and outdoor unit it is easy to get 13 / 14 SEER.

However just because the out door unit is rated at 15 SEER or above it is almost impossible to reach that efficiency level unless the furnace or air handler has a variable speed blower. Infact  15 SEER and above out door units  can be less efficient than standard equipment when not matched with the proper indoor unit.
