At Marr's Heating and Air Conditioning, we encourage area homeowners to schedule annual air conditioning maintenance in Sudden Valley, WA. Routine AC maintenance may seem like an added cost, but it will actually save you money over the long term. As equipment ages, electricity consumption can rise by as much as 15% in a single season. As the years pass, that inefficiency can get even higher. ACs that homeowners don’t service are also much more prone to breakdowns.
