I just had my AC checked out today, it's a Trane that's 2 years old. He said everything looks good, but he would suggest a surge protector. He says it's $, but he can do it for $. He says it's a 240V that would cover the outside AC and inside heater. Does this make sense or is it just something he wants to add on?
(the first time they came to check the heater, they gave me a "free" water heater inspection and they put on a new nozzle and anode rod.)
