A free, quick diagnosis for people staring down an HVAC decision — not sure whether to fix what you've got or start shopping for something new. Answer a few questions; we'll give you a straight answer and show our work.
Weak airflow, warm air, short-cycling, or it just won't keep up. Find out if it's worth fixing.
Start the cooling wizard →No heat, uneven heat, strange smells or noises, or it's cycling too often. Find out if it's worth fixing.
Start the heating wizard →Nothing's broken today, but you're wondering if you're due. Get ahead of the next breakdown.
Start the checkup →There's no single rule that settles a repair-vs-replace decision, but a few well-established ones get you most of the way there. We combine several of them into one straight recommendation, and we show you every reason behind it — no black box.
| The $5,000 rule | Multiply your system's age (in years) by the cost of the repair. If it's over $5,000, replacement is usually the better bet. |
| The 50% rule | If a repair costs more than about half of what a new system would cost installed, replacement tends to be the smarter investment. |
| Age & refrigerant | ENERGY STAR generally flags AC/heat pumps over 10 years and furnaces/boilers over 15 years for replacement consideration — more so if the system still runs on R-22, which is being phased out. |
These are starting points, not the whole conversation — repair history, comfort, planned renovations, and available rebates matter too. Our wizard walks through all of it.
