Transparent pricing
What does a new HVAC system cost in the North Bay?
Honest answer: it depends on the system, your home, and your ducts — so anyone quoting an exact price sight-unseen is guessing. Below are typical industry installed ranges to set expectations. They are not an Enviro quote; your real, written price comes from a free in-home assessment.
Typical industry installed range · not an Enviro quote
$8,000 – $20,000
for a whole-home heat pump. Coastal Northern California often sits at the higher end. Your actual price depends on equipment, sizing (a proper Manual J load calc), ducts, and access — all confirmed on site, in writing, for free.
“Isn’t the cheapest quote the best deal?”
Not usually. A lowball quote often skips the load calculation, uses an undersized or builder-grade unit, or leaves out permits and proper duct work — costs that resurface as high bills and early failure. Compare line-by-line scope, equipment, and warranty, not just the bottom number. That’s exactly what our Free 2nd Opinion checks.
Ranges shown are illustrative industry figures for education and are reviewed periodically; they are not a price quote or guarantee.
Energy savings · estimate
What does my HVAC cost to run — and could a high-efficiency upgrade pay off?
Older equipment burns more energy to deliver the same comfort. Tell us what you run now and we’ll estimate your current annual operating cost versus a high-efficiency system, shown as an honest range. These are estimates at today’s PG&E rates — your real numbers come from a free in-home energy assessment (and a Manual J load calculation).
$100$700+
Estimated operating cost · not a quote
Running it now
~$560 / yr
at ≈ SEER 10
High-efficiency upgrade
$310–$370 / yr
at SEER2 17+ (≈ SEER 18)
Save ~$190–$250 / yr
roughly 33%–44% less energy — about $1,900–$2,500 over ~10 years at today’s rates (energy prices have historically risen, so real lifetime savings are usually higher).
“How is this calculated — and will I really save that much?”
The honest part is the efficiency ratio: a system rated ≈ SEER 10 uses more energy than a modern SEER2 17+ (≈ SEER 18) one to deliver the same heating or cooling, so the savings track that difference. We anchor the dollars on your own bill (or a home-size estimate) and show a range, because real-world savings land at about 75–100% of the lab-rated difference depending on your ducts, usage, and weather. Figures assume PG&E residential rates of roughly $0.4/kWh electricity and $2.75/therm gas (early 2026). The only exact number comes from a free in-home energy assessment and Manual J load calculation — we never inflate savings to push a sale.
Estimate only, for education — not a quote, bid, or guarantee of savings. Actual operating cost and savings depend on your equipment, home, usage, and current PG&E rate plan.
