I can't rave enough about the superior customer service provided by SMW Refrigeration & Heating and their extremely knowledgable service technician, Paul Miller. SMW not only sent me an email appointment reminder but Paul also called to remind me about my checkup appointment, and he showed up on time.
Since air conditioning units are "out of sight, out of mind" I never remember to change out my ac filters. Now that I have purchased an SMW maintenance contract, I may actually remember to clean my filters regularly. It makes sense to have a maintenance contract if you live in the Valley of the Sun.
Paul was extremely helpful in explaining everything - how the ac system works and he even cleaned out the very dusty air filters. In short, you can't go wrong calling SMW Refrigeration & Heating. It's total peace of mind.
