Sentry Heating, Air Conditioning, Plumbing, & Electrical

Since 1985, Sentry Heating, Air Conditioning, Plumbing, & Electrical has served Birmingham area homeowners with 24/7 emergency availability and a 4.8-star rating across 387 reviews. Based in Vestavia Hills, the multi-trade contractor operates across 25 cities in the Birmingham metro, offering licensed and certified professionals for HVAC, plumbing, electrical, and generator needs. The company holds 12 industry awards and provides flexible financing options for major installations.

What distinguishes Sentry from single-trade competitors is their ability to handle complex, multi-system projects in a single visit. The company installs and services Carrier and Lennox equipment including heat pumps, ductless mini-splits, furnaces, and air conditioners. Beyond comfort systems, their licensed electricians install Generac generators, and their plumbers handle water heater replacements and PRV valve work. This breadth allows homeowners to coordinate a generator install, HVAC upgrade, and plumbing repair through one trusted team.

Reviewers repeatedly cite specific technicians who went above and beyond. Hannah described how Sentry installed a new furnace within 8 hours of her call during February's freezing temperatures, returning Monday to complete her AC installation. Joseph James praised Devonn and Ryan for thoroughly explaining their water heater and PRV replacement, noting the estimate beat a competitor's price. Jackie T. highlighted Hannia's clear communication while repairing her furnace control board, and Denise Franks called Jamie and James "top notch" for her garage mini-split installation.
