Accurately, No. A good appliance repair company will not provide any estimates by phone, it sets an inaccurate, bad expectation. Picture asking a car repair shop to give you an estimate for a repair on a car that the ac isn't working or is shaking. The root cause could be LOTS of different things. Any estimate they could provide would not be accurate until they could diagnose the issue. Having a good appliance repair technician onsite to perform a diagnosis will usually pinpoint the issue and give a clear path for estimates etc.
