HVAC Cost Calculator
Compare the true 10-year cost of traditional HVAC ownership versus a Comfort Plan subscription.
Most heat pump quotes show you one number: the install price. That number leaves out the things that actually decide what a system costs you over its life, which are repairs after the first year, annual maintenance, the efficiency the system holds onto as it ages, and what you pay in interest if you finance it. This calculator puts both paths side by side over ten years so the comparison is honest.
Retail ownership means you buy the equipment outright or finance it, and you own the maintenance and the repair bills after the labor warranty runs out. The CellSun Comfort Plan is a monthly subscription that bundles the equipment, the installation, scheduled maintenance and covered repairs into one predictable payment, so an unexpected compressor failure is not a five-figure surprise.
The estimate below is a planning tool, not a quote. Actual numbers depend on your home's load calculation, your existing ductwork or lack of it, your electric rate, and which Connecticut incentives you qualify for, including Energize CT rebates of $1,500 per ton and Smart-E financing at 1.99% APR. For a real number, ask us for a written, itemized proposal.
Recommended system size: 3 ton
⚠ Systems over 10 years old are at higher risk for costly repairs.
