Whole-home HVAC installation covers everything from a like-for-like system replacement to a full design-build for new construction or major remodels. We handle load calculations, equipment sizing, permit coordination, ductwork assessment, and heat pump rebate submission when it applies. We do not push any particular brand. We recommend what fits your home, your climate zone, and your budget.
What’s included:
- Load calculation (Manual J)
- Equipment selection across all major brands
- Ductwork inspection and sealing (or retrofit where needed)
- Permit pull and inspector coordination
- Full install with commissioning
- Rebate paperwork where applicable
- 10-year manufacturer parts warranty + 10-year labor warranty
How we size it:
Sizing is where most installs go wrong before a single tool comes off the truck. We run a Manual J load calculation, the method published in the ACCA and ASHRAE handbooks. It works from first principles: heat conducted through walls, ceiling, floor, and glass, solar gain through your windows, air leakage, and the heat your household and appliances give off. Each of those is driven by the difference between your indoor target, 75F in summer and 70F in winter, and the outdoor design temperature for your climate zone.
That outdoor design temperature is the value your area exceeds only about 1 percent of the year, not the hottest day on record. It runs near 81F on the East Bay coast, 92F in the South Bay, and 99F in the hot inland Tri-Valley. Sizing to a record extreme instead of the design value is the most common way a system gets oversized by a half ton, which then short-cycles and never runs at its sweet spot. We walk through that in what temperature your HVAC should be sized for. We size to the calculated load, not to a rule of thumb and not with a safety margin stacked on a number that already excludes the extremes.
Pricing:
- Basic replacement (single-stage AC + furnace): from $6,500
- Dual-fuel system: from $12,000
- Heat pump whole-home: from $15,000
- New construction or major retrofit: quoted per project
Timeline:
Standard like-for-like replacement: 1 to 2 days on site. Whole-home heat pump conversion: 2 to 4 days. New construction or major remodel: scheduled around your general contractor, typically 3 to 5 days of HVAC work. Permits add 1 to 3 weeks of lead time depending on city and inspector backlog.
What drives price:
Three factors move installation cost the most: equipment tier (single-stage vs. variable-speed), ductwork condition (intact vs. needs replacement), and electrical scope (existing circuit retained vs. sub-panel required). A house with intact ductwork and an existing 240V circuit installs faster and cheaper than a same-size home that needs a duct retrofit and panel work.
Ductwork:
Ductwork that is 25 years old or has visible damage usually needs to be replaced or repaired. Sealing leaky ducts can recover 15 to 25 percent of conditioned air. We inspect ducts on every estimate and tell you whether repair, sealing, or replacement makes the most sense for the new system you are considering.
What makes us different
Manual J load calculation. Every installation starts with a proper load calculation. Oversized systems short-cycle. Undersized systems cannot keep up. We size to your home's actual heat loss.
Every major brand, no favorites. We do not push any one brand. We recommend what fits your home, your climate zone, and your budget, then install it to manufacturer spec.
Owner reviews every quote. Every estimate gets my personal review before it reaches you. For installations and complex service, I meet you on-site. For routine calls, our trained technicians arrive with my license number on the invoice.
What to expect
Every job, repair or install, follows the same rhythm. No upsells dressed as "package tiers." No "today only" pricing. If the answer is "wait six months and re-evaluate," that is what we will say.
- On-site visit
Andrew measures, photographs, and asks questions about your existing system. $75 diagnostic, credited toward any repair over $200.
- Written estimate
Line-itemed, model-named, sized to a Manual J calculation. Sent same day, never verbal-only. Walk-aways are fine; no pressure.
- Scheduled install
Same crew start to finish. Permit pulled where required. 10-year parts plus 10-year labor warranty with bi-annual maintenance plan in force.
- Follow-through
We check the install at six months. If your utility bill did not move in the right direction, that is on us; we go back and find out why.
The diagnostic is seventy-five dollars and we credit it toward any repair over two hundred. If the answer is ‘your system is fine, here are the logs, call us next year,’ that is what the estimate will say.
HVAC Installation: common questions
Do I have to replace both heating and cooling at the same time?
How long does a full HVAC replacement take?
Do you coordinate ductwork sealing?
