Perma Services

Perma Services holds a 5-star rating across 18 verified reviews in San Francisco, California. This HVAC contractor serves residential customers throughout the city, handling heating and cooling systems in homes both old and new. Reviewers consistently mention the company as locally operated and family owned, a detail that surfaces repeatedly when customers describe their experiences. The business maintains a dedicated phone line at (800) 815-6404 for customer contact.

What distinguishes Perma Services is their commitment to single-appointment resolution. Multiple reviewers highlight the ability to move from diagnostic directly to repair without scheduling a follow-up visit, a convenience that proves especially valuable during San Francisco's occasional heat waves. The technician Danny earned specific praise for explaining repair options clearly and arriving on time, while Yahyl was recognized for troubleshooting a hard-to-find furnace part for an older heating system. Reviewers also note reasonable pricing compared to other quotes received, with one customer reporting work completed faster than expected and at a lower cost than alternative proposals.

Customers describe specific scenarios that illustrate the company's responsiveness. Rick Lopez needed urgent AC service because his father requires a constant ambient temperature for medical comfort, and Perma Services dispatched a technician within the hour. Another reviewer needed heat restored during cold November mornings, and Yahyl answered calls right away, located a rare replacement part, and extended the furnace's operational life. The technician who installed GG's AC unit took time to educate the homeowner on potential future issues and cost-saving maintenance approaches.
