They charged me $350 for just change transformer of furnace. Just 10 days later. It broken.
I called Ralph Cortez and never answer the phone.
$350 for transformer of furnace is too high. They over charged and did not repaired the problem.
The first time I left message to ask them for service, they responded very quickly.
The time they came to house for service, I was not home. They cheated my husband and told my husband the situation is very complicated. They did not tell my husband $350 first.
After finish, they told my husband the charge is $350. It is the way too high.
