Barbara S.

I had a catastrophic failure with my 25-year-old home central air conditioning. I contacted SIMS Heating and Cooling, they responded promptly, and diagnosed the issue quickly. Due to the age and repairs necessary on my old unit, I decided to replace it. SIMS kept me informed throughout the process and had me cool once again with a new unit in no time!
