Drop-In Refrigerants

R22 is the most common refrigerant in residential and light commercial A/C applications. It has been phased out due to damage that it does to the ozone layer, so availability is limited to existing stockpiles and refrigerant recovered from decommissioned machines. The sale of new equipment containing R22 has been stopped. However, units R22 compatible to existing system components are shipped “dry”, and then can be charged with R22 when installed. But that still leaves a lot of equipment stranded that is not yet at end of life. Some market players are saying that drop-in replacements are safe and effective. Others are saying no, that the equipment all needs to be replaced with new gear designed around R410a, a higher pressure refrigerant. Drop-in refrigerants can’t be mixed with R22. Others say it can.

Energy Recovery Ventilation

An ERV system delivers a fresh-air feel, with little or no energy loss. It transfers heat and moisture from inside to the outside of the home, balancing humidity levels for improved comfort. The system also sends pollutants outdoors, making indoor air easier to breathe. The many benefits are:

1. Provides cleaner, fresher indoor air. 2. Designed to provide comfort in warmer, humid climates. 3. Transfers incoming humidity back outdoors. 4. Will not restrict airflow for proper filtration.

What is Furnace AFUE & BTU’s?

The annual fuel utilization efficiency (AFUE; is a thermal efficiency measure of combustion equipment like furnaces, boilers, and water heaters. The AFUE differs from the true ‘thermal efficiency’ in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment, including the operating transients.[ It is a dimensionless ratio of useful energy output to energy input, expressed as a percentage. For example, a 90% AFUE for a gas furnace means it outputs 90 BTUs of useful heating for every 100 BTUs of Natural Gas input. A higher AFUE means higher efficiency. Read more.

Electronic Air Cleaners

By Betty Stephens

Indoor air pollution is among the top five environmental health risks. Usually the best way to address this risk is to control or eliminate the sources of pollutants and ventilate a home with clean outdoor air. Air filters and other air-cleaning devices are designed to remove pollutants from indoor air. Some are installed in the ductwork of a home’s central heating, ventilating, and air-conditioning (HVAC) system to clean the air in the entire house. Portable room air cleaners can be used to clean the air in a single room or in specific areas, but they are not intended to filter the air in the whole house. Read more.

Who Invented Modern Air Conditioning?

Willis Haviland Carrier

Willis H. Carrier is the true American success story and symbolizes everything that is great about this country. Good old American ingenuity at its best!

Childhood:

He was the only child born to Duane William Carrier (1836-1908) and Elizabeth R. Haviland (1845-1888). Willis Haviland Carrier was named after his mother’s uncle-in-law Willis Hoag Haviland, with whom she lived after the death of her father in 1868. The family lived on a farm near the snowy eastern shore of Lake Erie in Angola, NY. Read more.
