Common Questions
Frequently Asked Questions
Everything South San Francisco residents need to know about their HVAC systems.
How often should South San Francisco homeowners service their HVAC?
Given our mild but variable coastal climate, we recommend a bi-annual schedule: an AC check in spring before warmer days, and a furnace inspection in autumn. This helps maintain efficiency and prevents unexpected issues during cold snaps or heat spikes.
Do you service older homes in South City?
Yes! We specialize in retrofitting and maintaining HVAC systems in South San Francisco's historic properties, including those in Old Town and Buri Buri. We understand the challenges of older ductwork and architecture.
What if my heater breaks down on a weekend?
We offer 24/7 emergency repair services. If your system fails during a holiday or weekend, simply call (323) 487-6504, and our on-call technician will be dispatched to your home immediately.
Do you offer financing for new installations?
Yes, we understand that a new HVAC system is a significant investment. We offer flexible financing options to help make upgrading your home's comfort system affordable and stress-free.
