How old is your aircon? I bought some cheap Chinese "mini split" 3.5kW units locally for about 350 euros that go down to about -15 at about 2.5x effective heating to input (watts). They're closer to 4x at higher temps. Cooling runs at about 7x.
Aircons have become much cheaper and more effective over time. It might be worth looking at replacing your unit, assuming it's not something much more elaborate.
- jfengel 3y agoOld enough that I'm not gonna say out of sheer superstition. Old enough to raise eyebrows on the repair guy. When it finally has to be replaced the new one will assuredly be more efficient. But since it's already quite cheap to run (the very most expensive bill is perhaps $200 during a very hot August with me working from home), I'd love for this one to keep going as long as possible.
- dkjaudyeqooe 3y agoI'm cooling an approx 30m2 apartment with brick (cinder block) walls that are not insulated and I run the aircon continuously 24/7 all summer and use about 200kWh per month (approx $35 for me). Daytime temps are usually between 31 and 37 celsius and nighttime around 21 to 25.
