Installation FAQ
How much does a new HVAC system cost?
Cost depends on your home's size, the type of equipment, efficiency level, and whether ductwork or electrical upgrades are needed. After an in-home consultation, we provide a clear, written estimate so you know exactly what's included.
How long does an installation take?
Many single-equipment replacements are completed in one day. Complete system replacements or projects that involve new ductwork may take a few days. We'll give you a timeline with your estimate.
Do you offer financing?
Yes. Delcon partners with Hearth so qualified homeowners can explore monthly payment options. Financing is subject to credit approval.
Is a heat pump better than a furnace and AC?
It depends on your home and goals. Heat pumps heat and cool with one efficient electric system and suit the Bay Area's mild climate well, while a furnace and AC pairing may be a better fit for some homes. We'll walk you through the trade-offs.
How do you choose the right equipment?
We evaluate your home's layout, insulation, ductwork, and how you use each space, then recommend appropriately sized equipment rather than guessing based on square footage alone.
Should I repair or replace my system?
Not every problem calls for replacement. If your system is relatively young and the repair is reasonable, repairing often makes sense. When equipment is aging and repairs are frequent or costly, replacement may offer better long-term value. Our technicians will give you an honest recommendation either way.
