Once our NATE-certified technician identifies the problem, he’ll present you with options and the total cost of repair- including all labor and materials – BEFORE starting any work. Other companies charge by the hour, possibly leading to higher costs if you’re dealing with a slow or inexperienced technician. Our price doesn’t change – even if it takes us longer than expected to ensure the job is done right.
