Maintaining proper humidity levels in our homes is crucial for both comfort and health, particularly as the seasons change from summer to winter. The ideal indoor humidity level is typically between 30% and 50%RH. When humidity levels fall outside this range, it can lead to a variety of issues, including…
Using R-32 refrigerant offers several benefits over traditional refrigerants like R-410A and R-22. Here are some of the key advantages: Lower Global Warming Potential (GWP): R-32 has a significantly lower GWP (approximately 675) compared to R-410A (around 2088). This makes R-32 a more environmentally friendly option, helping to reduce the…
Recent changes in refrigerant regulations, particularly the phase-out of high-global warming potential (GWP) refrigerants, have significant implications for HVAC contractors in the Northeast. Here’s what these changes mean: Transition to Low-GWP Refrigerants: Contractors will need to adapt to using new refrigerants with lower GWP, such as R-410A alternatives (e.g., R-32…
