OUR HVAC INSTALLATION SERVICE

Full system design, installation, and commissioning

From $6,500

Brands we service & install:

Carrier Daikin Goodman Lennox Trane Mitsubishi Rheem American Standard York

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

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 can't keep up. We size to your home's actual heat loss.

Every major brand, no favorites

We don't 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 certified technicians arrive with my license number on the invoice. No high-pressure sales scripts. No passing of accountability.

We had a heater making some truly scary noises, so we called ADRIUM because several friends highly recommended them. Andrew was out here incredibly fast. He took the time to explain all our options — no pressure to upsell, just honest, considerate service. It’s rare to find this level of transparency and personal care these days.

FAQ

HVAC Installation — Common Questions

Do I have to replace both heating and cooling at the same time?
Not necessarily. If your furnace is failing but AC is fine (or vice versa), we can replace just one. However, if both are 15+ years old, replacing together often makes sense — shared install labor, consistent equipment compatibility, single permit. We walk through the math.
How long does a full HVAC replacement take?
Like-for-like replacement: 1–2 days. Heat pump conversion: 2–4 days. Major retrofit: 4–7 days. We schedule with you — you're not without HVAC for more than a day on standard replacements.
Do you coordinate ductwork sealing?
Yes. Leaky ducts waste 20–30% of HVAC output. We inspect duct integrity during estimate. If your ducts are undersized or leaky, we include repair or replacement in the proposal.
