We just had a service call for a water heater issue and SAC went beyond our expectations by responding with a quick and high quality oriented solution. We have used them in the past for heating and A/C equipment issues and installations and have had a similarly excellent experience. I recommend them without any reservations.

I used SAC for checking my AC & Furnace. The technician Steve was very knowledgeable and professional. He explained step by step what he was doing and showed me all the possible future issues that I should keep my eyes on them. No pressure at all to do extra repair or fixing. I strongly recommend SAC for any heating and cooling job. They are one of the top.
