Hey everyone! 👋 I'm Ryan Mitchell from Connecticut! 🏡 I work with the team at Crocco Mechanical, helping people stay comfortable with reliable heating and cooling solutions. ❄️🔥 I'm interested in HVAC technology, energy efficiency, and home comfort. Excited to join Mastodon, connect with new people, share ideas, and learn from this community. Looking forward to connecting with you all! 😊 #Introduction #HVAC #Connecticut

Questions for people who control their environmental temperatures with heat pumps (and only people with first-hand experience):

1. What is the optimal operating temperature range for your heat pump? (I.e., lowest temp it operates in efficiently for heating, highest temp for cooling)

2. When you can't use it because temperatures are outside that range, what do you use a back-up heating and cooling alternatives?

I keep reading about Corsi–Rosenthal boxes as DIY air purifiers that outperform all commercially available air purifiers. You literally only duct-tape four HVAC filters together and slap any regular PC fan onto them. US-Americans recommend the brand #Filtrete for MERV-rated HVAC filters, but in Europe that brand costs at least twice or thrice as much as in the USA. Are there any equivalent affordable HVAC filters in Europe with a MERV rating of 8 or 13? Or do I simply have to swallow the additional cost because HVAC filters aren't as ubiquitous in Europe as they are in North America? #DIY #CorsiRosenthalBox #CorsiRosenthal #HVAC #HEPA #MERV #AirQuality #AirPurifier #AirFilter

3 days during Maryland heat dome event. HVAC used 41kWh + 15kWh, so 56kWh with heat pumps keeping the house at 75f. My personal data center used 78kWh 😆 But it was all solar powered....and my neighbors too! #solar #heatdome #renewables #hvac #airconditioning #energy
