Common Questions
Frequently Asked Questions
Everything Half Moon Bay residents need to know about their HVAC systems.
How does the coastal fog affect my HVAC system?
The marine layer brings consistent humidity and salt air, which can accelerate corrosion on outdoor units. We recommend regular maintenance to clean coils and check for rust, and we can suggest corrosion-resistant coatings to extend equipment life.
Do I really need AC in Half Moon Bay?
While our summers are mild, recent years have seen more heat spikes. Many residents are opting for heat pumps, which provide efficient heating for our cool nights and cooling for those occasional warm days, offering the best of both worlds.
What if my heater breaks down on a weekend?
We offer 24/7 emergency repair services. If your heating fails during a cold weekend or holiday, 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.
