North Alabama comfort, year-round — free estimates on every job
An Alabama summer without AC isn't uncomfortable — it's dangerous. A January night with no heat is worse. SMS is the family-owned HVAC team Decatur and the Tennessee Valley have trusted for 12+ years to fix it right the first time.
We install, repair, and maintain every type of heating and air conditioning system — residential, commercial, and industrial. Our licensed, certified technicians show up on time, tell you honestly what your system needs, and quote you a fair price before we start. We arrive on time, respect your home, and work within your budget.
Regular maintenance with SMS catches small problems before they become emergency breakdowns — and a well-maintained system runs 15–20% more efficiently, cutting your monthly utility bill. Ask about our Advantage Maintenance Plan for scheduled visits, priority service, and 15% off parts.
TVA Quality Contractor status means SMS customers qualify for EnergyRight rebates and flexible financing options on qualifying new equipment — more comfort for less out-of-pocket.
Free estimates on all HVAC work — no-obligation, in-home or on-site. Call 256-686-3444 now — we answer 24/7
