Q. How is efficiency rating measured and should I always buy the best efficiency rating?
A. Gas or Oil Furnaces are rated in AFUE (Annual Fuel Utilization Efficiency), Heat Pumps in HPSF (Heating Season Performance Factor) and Air Conditioners in SEER (Seasonal Energy Efficiency Rating). With gas furnaces you should buy a model with a 92% rating if you run the blower continuously for better air filtration as it has a more efficient blower. However, if you allow the air to turn off when not heating, a 95% model will save you energy in the long run. On the A/C side it has more to do with comfort as you get to the higher SEER ratings in our climate. The base A/C is a 13 SEER for each point you go higher it uses about 10% less energy to run.
Q. Could my allergies be getting worse from not changing my HVAC filter?
A. Yes, as your filter gets too dirty its ability to capture and hold particles decreases and more dust and dirt can come through the filter. It’s important to use a good quality filter, typically in the 8-12 MERV range. Below MERV 8 it does not capture enough particles and above MERV 12 it is too restrictive to air flow.
