Most systems don't fail overnight. They slip — a little less comfort, a little more cost — until something finally gives.
- Rooms that never reach the set temperature
- Energy bills climbing with no change in usage
- A system that short-cycles or runs nonstop
- Dust that returns days after cleaning
- Equipment 15+ years old or still on R-22 refrigerant

Everything You Need to Know About HVAC & Air Duct Systems
Your HVAC system is more than the box in the garage or the unit beside the house. It's the furnace or heat pump, the air conditioner or outdoor condenser, the thermostat, and the ductwork that carries air to every room. When one piece is mismatched or underperforming, the whole system pays for it — in comfort, in efficiency, and in how long the equipment lasts.
That's why we start every HVAC project with the house, not the equipment catalog. We look at square footage, insulation levels, window exposure, and duct condition, then recommend a system sized for how your home actually gains and loses heat. An oversized unit short-cycles, wears out early, and leaves rooms clammy; an undersized one runs nonstop and still can't keep up.
Because Attic Star works in attics and crawl spaces every day, we see what many installers skip: crushed or disconnected ducts, missing insulation on supply lines, and leaks that dump conditioned air into the attic instead of your living room. Fixing those during a new install is often the difference between a system that performs as rated and one that never quite does.
Whether you're replacing a failing furnace, adding air conditioning for the first time, or moving to an all-electric heat pump, we'll lay out your options clearly — equipment, efficiency, and price — so you can make the call that fits your home and budget.
HVAC & Air Duct Systems at a Glance
What to Know Before Replacing Your HVAC System
In California, replacing a furnace, air conditioner, or heat pump generally requires a building permit, and Title 24 energy rules often require the ductwork to be tested for leakage as part of the job. Skipping the permit can create problems at inspection, at resale, or with your insurer.
Heat pumps have become the default recommendation for many Bay Area homes. One system handles both heating and cooling, runs on electricity, and handles the region's mild winters efficiently. Under rules the Bay Area's air district adopted in 2023, new furnaces sold and installed here are scheduled to meet a zero-emission standard starting in 2029 — another reason homeowners replacing equipment now are looking hard at heat pumps.
Efficiency ratings describe what equipment can do under test conditions: SEER2 for cooling, HSPF2 for heat pump heating, and AFUE for gas furnaces. Real-world performance depends on the installation — correct refrigerant charge, proper airflow, and sealed, insulated ducts — which is why the install matters as much as the equipment.

FAQ
How much does hvac & air duct systems cost? +
Cost depends on the size of your home and the scope of the work. We provide a free, no-obligation inspection and give you an exact quote before anything begins — no surprises.
How long does the work take? +
Most jobs are completed in a single day. Larger or more involved projects may take longer, which we'll confirm during your free inspection.
Do I need to be home during the work? +
You don't need to stay in the work area itself, but we do ask that someone is available at the start and end of the appointment. Our crew works cleanly and keeps you updated throughout.
Are you licensed and insured? +
Yes — Attic Star is fully licensed, bonded, and insured, and has served Bay Area homeowners for over 25 years.
Should I repair my HVAC system or replace it? +
If the equipment is under 10–12 years old and the problem is a single component, repair usually makes sense. If it's 15+ years old, needs a major part like a compressor or heat exchanger, or runs on phased-out R-22 refrigerant, replacement is typically the better investment. We'll give you an honest recommendation either way.
Is a heat pump a good fit for a Bay Area home? +
For most homes, yes. The Bay Area's mild climate is well suited to heat pumps, which heat and cool from one system and run on electricity. We'll check your electrical panel, ductwork, and layout to confirm it's the right fit before recommending one.
Do you replace the ductwork when you install a new system? +
Not automatically. We inspect the existing ducts with every install. If they're in good shape, we seal and reuse them; if they're undersized, leaking, or damaged, we'll show you what we found and quote repairs or replacement separately.
Do I need a permit for a new HVAC system? +
In most Bay Area cities, yes — replacing heating or cooling equipment typically requires a permit and a final inspection. We'll walk you through what your city requires before the project starts.
