Sullivan Service Co

Sullivan Service Co has kept Birmingham comfortable since 1959, making it one of the oldest continuously operating HVAC contractors in the greater metropolitan area. The company holds a Spire Certified Gas Contractor license and maintains an A+ rating with 102 verified client reviews averaging 4.8 stars. Serving residential and commercial customers across Alabaster, Hoover, Homewood, Mountain Brook, Vestavia Hills, and Pelham, this locally owned outfit brings over 50 years of hands-on experience to every service call.

What distinguishes Sullivan Service Co is their specialization in wine cellar climate control, a niche rarely found in standard HVAC companies. They back all labor with a 30-day workmanship warranty, and as a certified dealer for Trane, Mitsubishi, Daikin, and Carrier systems, they can match homeowners with equipment that fits both performance needs and budget considerations. Their financing program makes new system installation accessible without upfront full payment, while their indoor air quality division tackles filtration, dehumidification, and air purification beyond basic heating and cooling.

Homeowners consistently praise technician Alex, who guided Jan Love through a dual-system replacement with patient explanations of efficiency ratings and sizing. When Nancy Austin's AC failed unexpectedly, Richard arrived the same day and resolved both a maintenance need and a separate cooling complaint in a single visit. Bex Lauren Turner recalled comparing five different company bids before choosing Sullivan for a complete HVAC upgrade, noting Alex's honest assessment helped select equipment appropriate for her family's specific layout rather than upselling a more expensive model.
