Do not waste your money on a CostWay…
Do not waste your money on a CostWay mini split system sold by Home Depo. They will charge you for the unit. They will charge you for delivery of the unit. It is advertised as a DYI installation, but the installation instructions direct that you pay for professional installer. The unit ultimately will not have any coolant in it, although it is falsely advertised as being "pre-charged". When you call for customer service help, Home Depo will give you an incorrect number. When you Google the number yourself, a non-English person will claim to send you a troubleshooting guide via email. It will never be received. Meanwhile, you paid for an a/c unit that doesn't cool; a heating unit that doesn't heat, and paid two professionals to make a completely defective unit do what you paid it to do---yet it doesn't. Don't shop Home Depo.
